Lime Tek: Pasteurizing Sawdust Pellets with Lime 3
#19367080 - 01/04/14 07:09 AM (10 years, 27 days ago) |

The lime bath method for pasteurizing straw has had such an immense impact on my vision of mushroom production. Though we currently don't use straw on our farm; im sure at some point we will. When we do, we will be using the lime bath method. For now, Id like to experiment with sawdust and lime. I know there is some info about this; but I would like to do some trials and have a basic discussion thread on using lime to treat sawdust for spawning. THANK YOU SOLARITY for the lime to H2O ratios; and my bluelab trimeter verified it 
Approximate ratio of lime:water to achieve a PH of 12.5 is 2g hydrated lime : 1L of H2O 1/3/2014 - Started Brown Oyster "213" experiment. -Made 9L of warm lime water(5g/L not 2g/L) poured it onto 9KG oak pellets and .5KG pelleted gypsum. -Mixed in cement mixer for 10 minutes. -Added 1.8KG of brown oyster "213" rye grain spawn. (200g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes. -Loaded into a large column type bag (and filled 1 filter bag as well) -Poked holes in bag; incubate at room temp *Possibly too much lime in water; slow growth?- 1/13/2014 -Fully colonized with no contams (10 days); Begin consolidation - 1/31/2014 -Put into FC (28 days incubation); Pins formed invitro within 3T bag - 2/8/2014 -Harvested 1st flush (9 days in FC); YIELD: .5lbs; pictures on page 5 1/6/2014 - Started Blue Oyster "PL" Experiment -Made 9L of warm lime water(2g/L) poured it onto 9KG oak pellets and .5KG pelleted gypsum. -Mixed in cement mixer for 10 minutes. -Added 1.8KG of blue oyster "PL" rye grain spawn. (200g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes. -Loaded into a large column type bag (and filled 1 filter bag as well) -Poked holes in bag; incubate at room temp - 1/16/2014 -Fully colonized with no contams (10 days); Begin consolidation - 2/3/2014 - put into FC (28 days incubation); cut 2 X's in bag - 2/15/2014 -Harvested 1st flush (12 days in FC); YIELD: .5lbs 1/6/2014 - Started Shiitake "Jumbo" and "3782" Experiment- Made 2 batches of 12L of warm lime water(2g/L) poured it onto 12KG oak pellets and .6KG pelleted gypsum. -Mixed in cement mixer for 10 minutes. -Added 1.8KG of shiitake "Jumbo" rye grain spawn to the first batch and 1.8KG shiitake "3782" rye grain spawn to the second batch. (150g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes. -Put on gloves and loaded into 8 3T-filter bags at 3.3-3.6KG/Bag - 1/16/2014 -Minute amounts of green mold growing on both the Shiitake batches. So minute that most of the bags have already ate the green, and the small amount left looks like it will be consumed soon. Besides this, the blocks look great. Contam sources: Not enough spawn (used less than oysters) or not enough lime. - 1/30/2014 -Green mold has been fully consumed by mycelium. 3/13/2014 - Started Brown Oyster "213" %20 bran experiment.-Made 13L of warm lime water(4g/L not 2g/L) -Added 2.4KG of bran to the lime water and stirred to saturate bran -Poured Lime H2O + Bran slurry onto 9KG oak pellets and .5KG pelleted gypsum. -Mixed in cement mixer for 10 minutes. -Added 1.8KG of brown oyster "213" rye grain spawn. (200g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes. -Loaded into 9 3T-filter bags at 2.7KG/Bag 3/13/2014 - Started Shiitake "Jumbo" Experiment-Made 11L of warm lime water(4g/L not 2g/L) poured it onto 12KG oak pellets and .6KG pelleted gypsum. -Mixed in cement mixer for 10 minutes. -Added 1.8KG of shiitake "Jumbo" rye grain spawn to the first batch (150g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes -Loaded into 9 3T-filter bags at 3KG/Bag 3/13/2014 - Started Shiitake "3782" %2 bran Experiment-Made 12L of warm lime water(4g/L not 2g/L) poured it onto 12KG oak pellets, .6KG pelleted gypsum, and 220g bran -Mixed in cement mixer for 10 minutes -Added 1.8KG of shiitake "3782" rye grain spawn to the first batch (150g wet spawn per 1KG dry sawdust) -Mixed in cement mixer for 5 minutes -Loaded into 9 3T-filter bags at 3KG/Bag NOTES:- Using 4-5g/L of hydrated lime in H2O instead of 2g/L showed only a slightly slower growth rate, but seemed to be much more resistant to contams. I am thinking that since I am using lime H2O to hydrate and not to soak the sawdust, that if you add more lime to the point that it precipitates out of the H2O it still ends up in the sawdust after re-hydration (which wouldn't happen with soaking). This "extra" lime may provide long term resistance to contams, as it may keep the PH up for longer periods of time. More experimentation to be done on this.

nice to see some serious experimenting being done
but wouldn't it be better to use it on un-pelletized sawdust? as pellets will do fine with just hot water poured over them, and ''normal'' sawdust will have more contaminants

Well, im using what I have; and that is pellets. I think pellets have a higher chance of success, but I think success with sawdust would have much stronger implications. I am going to do this with hot water too. But I want to try it with lime, because eventually I may want to try supplementing with low bran %'s. Also boiling gallons of water takes longer than mixing lime water.

Am in midst of trying this out with Reishi, King Oyster and Pink Oyster. I used two different concentrations of lime, curious to see how that goes. I was wondering about the gypsum, should it be added after the soak? Since it buffers pH?

I like the idea of figuring out an upper limit with supplements of like usage would be an excellent find indeed. Since my basement farm is no more right now I played around with some oyster spawn I had laying around. I'm sure some of you have seen the guys video using food grand H2O2. I basically tried to replicate that. I didn't make lime water, but I did toss my pellets in it to evenly coat them. I added the peroxide and gypsum to hot tap water, somewhere around 130 F. I also added a supplement I was using when in was pasteurizing straw, a store bought composted chicken manure product. I mixed everything together in a tub, let the substrate cool to 100 F then added my spawn and portioned out into filter bags.
Here's my recipe:
15.5# oak pellets 25# hot tap water 1 C. 35% food grade H2O2 2 Oz lime 12.4 Oz chicken manure 4 # oyster rye spawn
The temp read 125F after mixing and took about 2 hours to cool down to mixing temps. Unfortunately I don't have a pH meter anymore so from that stand point I can't say where I'm at. This was on 12/24 and the bags are nearly colonized now.
I know this isn't exactly your experiment Aleon, but my plans were to next time cut the peroxide out and just use lime and varying amounts of the chicken compost for supplement until I hit an upper limit. I guess I should try bran also and get another pH meter to keep in line with what you started the thread for. Keep us updated.

cool! but like forrest was getting at, you probably could have just added hot water and been fine. with the pellets that is. Now bran, that's dangerous- but I like it!

Aleon, did you check the ph of the limewater with smaller amounts of Ca(OH)2 - As it reaches saturation point at 1.5g/L the rest will just precipitate out (hence the milky look)
I used straw soak to make up a test run of 30 small straw bags inocc with Pl.Ost, - great results! Then I did a run of 50 - also great. Then I did 146.... and got 146 contaminated bags. I have also repeatedly tried with KO (straw/Sawdust/Alfalfa and mixes thereof) but only got contams, though I think this may be to do with the slow KO strain I was using. About to try with some hopefully more aggressive strains.

I have oyster and king oyster on small straw logs pasteurized using a lime soak. It is 34 Celcius here (90-110 F) and both king oyster and oyster bags have fully colonized within 2-3 weeks. I am just waiting for my fruiting chamber to induce pinning.
I had some contaminants but it was expected the straw was too wet, not chopped enough and some bags not compacted enough.
One bag that looked really good showed up trich spots. I removed the collar to try and fruit it and separated it.
I am waiting for fuel pellets and it was my intent to mix straw with pellets and pasteurize the whole thing using lime. By using higher grain spawn ratio you shouldn't need to supplement shiitake blocks so I don't have to sterilize any substrate. I'm all for lazy options 
I will post my results here in the coming months...keeping an eye on your progresses

I hope your fruiting chamber is a lot cooler than that or you may have trouble getting your kings to pin!

Why do you think your biggest batch failed, Solarity? Could the PH have been too low? different sawdust mixture than the first two trials? different strain?
*Just noticed you are using straw instead of sawdust.

I'll have to look at my notes at the time but the sub was the same the spawn was the same. Could have been soak time could have been ratio, the amount of water is eyeballed in a 750L tank. They colonised just fine for 10 days then day 12 was trich city. These were for kits so they are abt 1.4kg straw in a filter patch bag. I dumped all of the contaminated bags outside with a cut in them, quite a few fruited.

I've been experimenting with lime too and I feel its promising to use on grain/coffee/sawdust without PCing, it just needs to be dialed in.. I have a test grain spawn and rye seed jars that have yet to develop any mould or anything after a week only boiled in lime water.. so I think its gonna work:)

Add gypsum for the minerals not its effect on PH. Add it whenever.
Chef- Interesting experiment; keep us updated, especially on the chicken manure as a supplement

I prefer to do lime bath. Im planning on making 100's of bags a week like this if it works. Im not going to carry 5 gallons boiling H2O from my stove, down the stairs, pour it into a cement mixer 10-20 times a day. I know a few people who have nasty scars from spilling boiled water doing things like this. Lime water can be mixed in a second (whereas it takes me about 1 hour to boil 5 gal H2O which is expensive since im on LP out here in the country), and is safe to the touch unlike boiling water. Also, on a side note, im a chemical kind of guy 
Solarity- thanks for the tip on lime ratios; I will try yours and see if it gets me to PH 12.5 then update the OP with the new ratio. Also it aint over till 14 days after colonization. Green molds can appear late in the game.
Forrester- what kind of yield are u getting from your blocks made with the hot water tek; and how long incubation?

I don't grow commercially so I've never bothered weighing, or if I did I've forgotten. They usually incubate for 2 - 2.5 months. Yield seemed decent enough for my purposes but I've never supplemented to compare so I'm not much help there

So far everything looks fine. The first experiment im pretty sure i added too much lime (THANKS SOLARITY). Its growing but super slow. I did 3 other batches of this; 1 jumbo shiitake, 1 3782 shiitake, and blue oyster. The blue oyster is already further along than the OG test. SO im blaming it on too much lime. I found that 1.5-2g/L lime was right (i used 2g/L) to get PH 12.5. I'll update OP. Also i have not been "soaking" the pellets in lime; im hydrating them with lime water in 10 minutes. No excess lime water to create a disposal hazard. I also got some chick-a-dee doo doo bagged chicken manure that i would like to experiment using as a supplement once i get some pure lime sawdust runs in.

I did another batch on 1/6. Again, and sorry for not really being within the parameters of the OP experiment, but here's what I have. The main goal of my wanting to supplement pellets using a high lime concentration, possibly peroxide if it helps me push the upper limits of supplementation, is for my grow your own kits for the up coming farmers market. I had a bag of spawn in the fridge dated 2/12 of last year. Its FF's pohu strain. So I decided to go very heavy just to use it up. Again not what I would do in my commercial scale. Here's the latest recipe used.
Oak pellets 3.1# warm water 5# F.G. 35% H2O2 1/4 C. Lime .4oz Chx compost 5oz Gypsum .4oz Spawn 4#
 
Both nearly ready to fruit. Next batch im going to drop the H2O2 and use a regular spawn amount.

The 1/3/2014 experiment has colonized successfully. The other experiments are looking very good (i highly doubt contams will come in) especially the Jumbo shiitake; which is growing faster with less spawn than the oysters.
Now that i know contams are not the problem; what about speed and yield? These are what i will be closely recording. Well speed is already slower as this oyster strain (213) always goes into fruiting at 8-10 days Inc.on sup. sawdust, But i am willing to be patient and also experiment with supplements to increase speed and yields if they are lacking initially.

I have been adding lime to my bucket tek water to make oyster buckets and it works great and seems to speed up colonization and I havent had the contamn problem I had for a few buckets. per bucket its been about 7.5 qts of water to 8 qts of pellets with a tbsp or 15ml volume of lime added. I know i'm not going as deep into the numbers as you guys but its working. I am still heat pasteurizing though. Not sure why my buckets were contamning. Maybe they were too wet. I can't seem to get any of my azul strain oysters to even fruit out of buckets :/

i am looking for a bulk patereusation method as my PC cant handle the amount of substrate i need anymore... lime sounds interesting... but i thought lime method was for straw substrate only, no bran, no supplements no sawdust.... as you can not drain it...
do you drain your substrate mix? as i noticed you use oak as well... you just put all ingredients together and bag it? or you let it drain...?

Yeah me 2. I mainly wanted to learn/explore this for shiitake since i only use 2-5%bran when i sterilize anyways. I am expecting a 4 month colonization time, so it will be a while lol! I actually made my blocks huge (8lbs or 3.6KG) because i didnt need to sterilize or mix them after they had been loaded into bags. This will increase my yield/ft3 and decrease the use of plastic.

Hey Aleon. One question, did you use the same ratio of spawn for the shiitake blocks (200g wet for 1000g dry sawdust)?
ok two questions do you expect 4 months before browning?
thanks for sharing your experiment.

I need to update the OP with these other experiments. I did 150g wet spawn to 1KG dry pellets for the shiitake.
I expect it to be ready to fruit at 3.5-4 months.

the idea about lime pasteurisation is creating a PH of 12 right? is it therefore ok to use another material for creating ph of 12, instead of using lime? i can get my hands on KOH. so would like to try the lime method with KOH. it only cost me 0,74ct/kilo and liquid so easy to mix with the water....would this be a good idea?
hydrated lime that i can get has a high Mg content and i believe that is not good.

A high Mg content is not good. Im using the HI-Yield Brand of hydrated lime now. Id be interested in your results as i always have KOH around for hydro solutions too. If it is just a PH thing (which i think it is) you should give it a try Also the added Potassium could boost growth as well. I think that the calcium in hydrated lime provides additional calcium for nutrition to the mushrooms as well?

What I don't understand is...the ideal ph of substrates for a lot of strains is they say, 6. If it's soaked in ph 12, what is the end ph?

As the fungus colonizes the substrate the PH decreases due to the acids the fungus create. Hopefully by the time the mushroom colonizes the substrate or shortly thereafter, the PH should be ideal for fruiting.
Lime will work for the Calocybe sparkle. You should give it a try!

I was mixing a very high amount of lime into my casing for king oysters. I would assume, if you don't already, adding a good dose of lime to your casing will help eliminate your weed mushrooms sparkle.

i'm thinking there is still a lot or room for adjustment of the procedure to species that now won't tolerate the lime treated substrate.
for example like i mentioned in another thread afterwards adding an acid to neutralize, then the substrate would be at the same point as heat pasteurized when it's cooled down before inoculation, unprotected against new invaders except by the (wanted) micro-organisms that survived the treatment.

I think ph buffering is never a real requirement for a substrate, and here you want to create a pH swing, so a buffer is the last you'd want...

Ok yeah, that makes a lot more sense. So if I'm understanding this... Hydrated Lime is used for making a ph swing. Calcium carbonate is added to create a ph buffer. Gypsum is added to improve physical properties of substrate (and does not effect ph). Finally hydrated lime will decompose into calcium carbonate and also helps swing the ph. Is this correct?

yeah pretty much i'm not sure how fast the conversion of hydrated lime to calcium carbonate is, it might be really slow, and the main reason for the dropping of ph after adding it to a substrate might be by acids secreted by the fungi or bacteria. and gypsum is also a ph buffer (if i'm not mistaken)

I think just the overall ph of the straw or sawdust does it. Since we only do about 60 percent water to bring it to capacity, the other 40 percent is of a lower ph. Or at least that is my way of thinking.

do you have a source of straw or sawdust neutralizing an alkaline solution? pH is only applicable to liquid, but you mean the straw or sawdust release acids into the water?

I probably didn't word it correctly. But the ph of the tea or whatever you would call it of whatever in the straw leeches into the lime bath. I'm still unsure how to word it lol. I just know that when I create a lime bath and get it to 12 it drops to 10 or maybe lower after soaking the straw in it. Not sure what in the straw does it but I'd guess it'd do similar with the sawdust. I'm just guessing though since when I've used it with sawdust I just add the proper amount of lime to the water to reach capacity. With straw I just make a bath and do multiple batches of straw and have to add more lime each time even with the same amount of water to achieve the same ph. On the subject arent there testers to test the ph of soil? Or I thought you could test the ph of a non liquid by adding equal amounts of the non liquid and water which should be 7 but usually isn't then taking the mean value of the two? If not I shoudl probalby quit posting this late lol

Ok so in keeping in line more with the OP's parameters I have done a little project to test the limits of supplementation with this process. I have used composted chicken manure, soybean meal, cotton seed meal, and corn gluten for supplementation's in this experiment. I made 4 bags with each supplement at 5%,10%,15%, and 20% dry weight to total dry weight of the substrate. I used a ratio of 40% dry weight to 60% lime water in this experiment. Well, kind of. After I did the first two batches with this ratio I began to think the water levels too high so I cut them back to 55% water to 45% dry. But still kept the dry ratio of supplementation the same.
Here is the basic recipe I used:
1L H2O= 1000g( slightly over but used 1000) 1L H2O to 2g hydrated lime
Each bags make up totals at 2300g 920g Dry(40%) to 1380g water(60%)
5% Supplementation
46g Supplement 4.6g Gypsum(.5% total dry weight) 2.76g Lime(.002g/1g h2o) 869.4g Oak pellets 1380g Water 212.5g Spawn
10% Supplementation
92g Supplement 4.6g Gypsum 2.76g Lime 820.64g Oak 1380g Water 212.5g Spawn
15% Supplementation
138g Supplement 4.6g Gypsum 2.76g Lime 774.64g Oak 1380g Water 212.5g Spawn
20% Supplementation
184g Supplement 4.6g Gypsum 2.76g Lime 728.64g Oak 1380g Water 212.5g Spawn
Now I came to a few realizations I all of this. First, check the Ph of your tap water before you assume any lime to water ratio. My starting ph of warm tap is 10.2(+/-). I know my area is known for lots of lime in the water and I guess this is the result of that and treatment. So I used the 1000g to 2g ratio and came up with water having a ph of about 14.2-14.8

I still used this 14.6 water for all of my hydration based off of Aleons notes about additional amounts.
The spawn I used is about a year old, but a good commercially made Pohu. It seemed ok and had been refrigerated.
Here are some pics of the process.
  Top left= Soybean meal Top right= Cotton seed meal Bottom left= Corn gluten Bottom right= Chicken manure compost
 Dry ingredients portioned out
 Batch mixing Everything went into filter patch bags and was sealed. So now we wait. Im really in this to see how much we can push this with out contamination. I don't have a fruiting room set up so not sure how yields will come out but I may use my outdoor greenhouse to fruit. Ill keep posted.

I forgot to mention I did a control bag with just sawdust, lime, gypsum, and water with the same spawn ratio. This morning all bags were starting to jump off. So far so good. Ill be keeping track of speed of colonization as well as contamination. Inhave them incubating at 72F with the bags with the greater amount of supplement on the cooler parts to avoid heat buildup from supplement. The bags with the original ratio of water that I thought might be to wet are probably fine, just on the upper limit of hydration. I think the 55%/45% water to dry is a better ratio for these pellets.

I fall in this crowd. Hello everyone, I've been reading the forum for a while and am very interested and new to mushroom (medical and culinary) growing. The main idea of this thread is to not have to sterilize or pasteurize your bulk material correct?
And, if I'm new to growing mushrooms, would this 'lime-tek' be a good way to start? It seems really easy w/o the pressure cooker...

Buy some ph test strips and recalibrate your ph meter. I would be surprised if you water had ph that high.

Ha I know that's what my dad said. I calibrated it before I left that day with 7ph calibrating solution. But test strips would be a bit more reassuring. I remember getting similar results with my home tap water when I was doing aquaponics. But my solution is a few years old so not saying its entirely accurate. Its a cheap meter also.

Damn. That's crazy. Our's is 6.1. Seems like that would corrode ur pipes pretty quick with lime scale huh.

Ya lime scale is a constant problem. I find lime pebbles in my drip irrigation filter about every month. C.L.R. is a staple around these parts.

I just bought a ph meter, because test strips were telling me my ph was 10 no matter how much lime I added. Either that or I'm color blind lol. Did tests in a five gallon buckets, and I kept getting the same shade of blue everytime the ph went over 8.
I'm still struggling with the lime tek on my farm, going back to heat for a little while till I can get it sorted out. I get slow growth and then bacteria on most bags. I thought the problem was my spawn, and it may be somewhat, but I got some commercial pohu from a friend and same issues. I wonder is the water temperature has some effect? On the days I've made logs, ambient temps were in the low 50s. Could the cooler temp of the straw slow the myc down long enough to allow contams to take over? THe bags wre immediately placed in a 75F room. *shrug*

are you trying lime bath on straw or sawdust. The strain of oyster makes a huge difference in my opinion. you want a super vigorous strain that tolerates high ph. AKA- commercial strain like gray dove, brat, etc. I am leary of lime tek for sawdust personally. I think part of the problem is that sawdust is already very low ph. It may be more difficult to change the ph of sawdust by soaking in lime than it is for straw. that said, folks are trying it and having some success on sawdust.

Lime water tops out at pH 12.3 add more lime and it just goes into suspension to give the milky look.

I was getting pH readings in the 14ph range. There was lime that settled out of solution, but it still read that high. Now like I said earlier, it may just be my pH meter. But my starting pH is also very high. Is there a maximum pH lime can produce or is this just the highest you have seen polarity?

Amanita, I'm using straw. Guess I just need to keep experimenting with strains.
So according to that info, chefin, I'm guessing it's impossible to add too much lime? Or will the non soluble particles mess with mycelial growth in some way? If the average strain likes a ph of 6, it probably won't be thrilled running into solid particles of lime sprinkled through the substrate

Thats it's max. The linked doc concurs. Though if the water was very cold then you are approaching 14. Sus pH meter!

The fact that only so much will dissolve and using that table and a thermometer would make lime a good pH meter calibration solution!

I have the same problem with testing my lime solution. My strips just never go higher than 10 no matter what I add. I just add til i get a reading of ten then add one more 1/3 cup to my 25gallon or so solution. Probably much less :/ I feel like I'm wasting lime though. I need to get an electronic ph tester. my water is usually no warmer than 50 degrees i bet. So this is a good temparature range to just wait for no more to mix into the solution then stop? I always have a white milky mixture. But it should never have any white appearance when its at 12? If so I will just start eyeing the solution to tell me.

I have purchased two types of ph strips, one i got from a brewery supply shop, the color chart on this brand only goes to 10 and from my testing this is true, it only goes to blue (10) and wont read any higher.
The other strips i bought from a local lab supply store and the color chart goes to 12 (purple). the same water that will read 12 on these strips will read 10 on the other strips.
So to those of you who cant get a reading over 10, i would suggest using different ph strips. The strips that give a reading of 12 are easy, cheap and reliable.

Won't work as well with sawdust. The reason pellets work is that the extrusion process generates a lot of heat. So the pellets are semi sterile. Sawdust is FULL of microbes. I guess it depends on the quality of ur sawdust though. If it is kiln dried and straight out if the wood workers mill it might still work. But pellets and sawdust are two different animals in terms of contamination IMO.

Just made some bags today and yesterday with a mix of lime past. rice hulls, soaked for 18hrs, and saw dust done in this fashion. Supplemented with cotton seed hulls. Looking to speed up colonization by adding some materials to aerate the substrate, without having to use/chop straw. I don't have the recipes on me but ill post more later.

Right now, as per the chart I found and posted earlier in the thread, im using 1.8g lime to 1L(1000g) water. I have taken temperatures of water and added differing amounts until precipitation and the chart is pretty accurate. I should be getting my test strips in the mail Monday. My ph meter is still reading high, though calibrates accurately when the ph is near or at 7 in calibrating solution and distilled water.

So here is the latest batch of experiments. I bought some par boiled rice hulls from the greenhouse supply place. It was 50# for $15. I am still looking for a source of soy hulls, but cant find a place that I don't have to buy a ton. Not a problem when I have my space, but no where to put them now. Any way, my aim is to aerate the wood substrate in hopes to speed up colonization, and still get yields I need, plus only using lime to process the substrate. I did a few different things.
On 1/31
I mixed two bags, one with soaked rice hulls and one with dry hulls. I used about 20% hulls to 80% oak pellets. I wasn't sure if just mixing dry hulls in with the dry pellets and adding the lime water would be enough to hydrate the hulls, as they don't hold much water. Though I think it worked just fine. Here is the bag with dry hulls added in.

Here is the bag with soaked hulls(just in water not lime soaked):

Both of these bags were supplemented with 20% cotton seed meal and about 8% spawn. The recipes are on the bag if you can read them, if not ill edit them in.
So after I got done mixing these bags I thought it might be a better idea to soak the rice hulls in lime water for 18 hours like you would with chopped straw. So I did that and mixed some more bags. This time though I did a 50-50 mix of rice and oak pellet by dry weight, 20% supplement by dry weight, and lime water. The advantage of adding sawdust to a hull is you don't have to press the hulls or even really drain them that much. Just adjust the additional water added to the dry pellets to leave them dry enough to soak in the excess water from the hulls. Seemed to work well. I just filled some 1mil poly bags I had at work.

You can see from the pics that the 80-20 bags made 1/31 are almost fully colonized already. So im seeing the advantage of the extra expense of the hulls, as long as the yield is there.
Here is the just for fun millet spawn bags I put together. Surprisingly not contaminated and nearly fully colonized. I posted about these in the other thread on this subject, just don't feel like doing another post right now.
 
Someone else please try this. It seemed to work. I cant imagine it having consistent results though. But who knows?

that's great! it will probably serve best as a low tech method for people new to mushroom cultivation, for those who don;t have a pc yet, like the pf-tek, but will indeed probably not give consistent enough results for more intensive growing.

The coolest thing is the ability to use the method in third-world countries, backwoods grow ops, or anywhere you only have fire as a heat source. Could be great for cloning wild specimens too, if it pans out.

Hey there folks, had enough of winter yet? I wrote this on another page and I don't know why I didn't post it here before, but...
Quote:
On the three that are cased I used Red Oak sawdust, vermiculite, wheat bran, and hydrated lime and oven pastuerized at 200F for 3 hours. The casing was pasteurized 50/50 fine verm/peat moss. The 4 un-cased tubs were Red Oak sawdust, straw, hardwood mulch, wheat bran, cottonseed meal, and hydrated lime (done in the oven the same way). Each tub was 4-5 qt of substrate spawned with a 1/2qt of grain spawn. I don't think is was the oven pasteurizing that worked. I believe it was the lime. I vacuum sealed all the mixed dry ingredients months before hand, and just added water before putting it in the oven. I'll have to dig out my notes, but I think I used 16 cups sawdust, 12 cups of coarse verm, 8 cups of bran, and a cup of lime per batch. Don't quote me on that though, I may be wrong. I still have a couple "logs" I think.
These are the pre-packaged "logs" of dry mix I was talking about above.

I can't find my notes on the ratios I did for either of the substrate mixtures now. Oh well. I did 3 cased and 4 uncased each of King and Pearl Oyster, and two small vertical logs of the Pearls as well. I flushed each of the 14+ blocks I made twice, then put them in fresh filter patch bags to be stored until spring outdoors growbed time. They still haven't shown any type of contams on any of the blocks. I'm confident in saying supplemented sawdust doesn't need PC'ing at all. Lime works just fine. Here's a wall of pics.

To be honest, the oven thing was mainly because I got the mixture a bit too wet and wanted to dry it out some. I have read that oven pasteurizing will usually fail, but I figured the lime would balance it out. I put a solid clay brick in the center of a metal washtub and poured the substrate all around it to help equalize the heat better, then covered it with foil (holes poked in it to allow evaporation). Half way through the bake I opened the tub and thoroughly stirred the substrate.

Good stuff guys. Inspiring Ghia!
Here's a quick update (also updated in OP):
For the Oyster "213" 5lb block i got .5lbs mushrooms on the first flush on 2/8. It took 36 days from inoculation till first flush (28 days incubation). With %20 bran i get 1st flush in 16-21 days from inoculation, and get 1-1.25lbs on first flush (also using 1/2 the spawn). Very dense and high quality mushrooms, but lower yield. Still acceptable in my eyes because of how easy it is to make-up (its perfect for a low tech home grower just getting into the hobby! Or making sawdust spawn to inoculate outdoor beds!) Next im going to try some bran in there as well and see if i can up the speed and yields.

The Shiitake's are still consolidating; nicely.

Thanks, Aleon. My idea of adding the lime to the dry mix before vacuum sealing was because the fresh sawdust (got it coming out of the chute at the sawmill) still had moisture in it and I didn't want the bran to mold. It was mainly an experiment on pre-packaging supplemented substrate for later use, and sale. That's why I saved a couple logs. Gonna test them out on this next round. Not sure what I'll spawn it with yet, gotta wait and see what grain bags do the best first. Test fruiting all the species I collected for the first time is kind of a pain in the ass, but is exciting none the less. After getting two mislabeled plates in a trade I wanna make sure everything is what it's supposed to be.
That is quite a difference in yield between the two on the first flushes. How many flushes you going for per block, as many as you can?

So here are some of the results from my initial two projects. The first one with the peroxide, lime, and chicken compost mix with pellets. It took about 40 days to colonize then about 8 days to fruit. Now I did have them in our cold room at work which stays a constant 55F, so may of been the reason for the slow fruiting. Off a 5# block I harvested 1#1oz. Not bad for a mix and bag preparation. Here is a 8oz cluster and the block pinning in my make shift SGFC.
  
Mind you, that spawn bag was a year old.....
Now here are some of the bags pinning that have the varying supplement at different rates. I had a few of them grow green, but those were the ones I thought to wet from the beginning. They did colonize and I will still fruit them.
 This one is 10% cotton seed meal.
 This one is 20% corn gluten. It is pinning like crazy!
They all took about the same amount of time colonizing, about 30-35 days. Which when was running 20% bran supplemented sterilized blocks this was about the same.
Here is one of the first "grow your own" bags I made up

I have everything at home in my orchid greenhouse, so far everyone is getting along.

Recently I have been playing aroung with adding rice hulls to the pellets to expedieate colonization. Its working well. I have done 20% rice to 80% pellets, and 50/50 rice to pellets. I have done a few preperations with both. I have lime soaked rice for 18 hours, drained, then added pellets to the mix to help absorbe excess water and give the substrate better water holding capacity.

Here is a close up of what the sub looks like.

This spawn run is closer to that of straw logs. The bags I made on 2/8 are about 50% colonized already. They are in poly tubing not filter patch bags as well.
 
Then 2/9 I mixed up a bag by simply putting 50% rice and 50% pellets dry, then 10% supplemented with chicken manure. The recipe is on the bag. I then simply added 12.5 ph lime water and mixed for 10 minutes until the pellets were broken up and the hulls were hydrated. To this I added about 30% lime processed millet spawn. I know its a lot of spawn, but I didn't have anything else besides the experimental lime millet spawn I made.

All in all everything seems to be going well for low tek, simple, quick preparation methods.
PS- sorry for the long winded post......

Interesting results (actually amazing), by my calculations (given 70% moisture content) a 5lb block at 100% BE would be 1.5 lbs of mushroom. so chef and aleon, you are both close to achieving that on the first flush.
It seems you would expect a little higher yield if you had sterilized, any hypothesis as to why lime pasteurization with supplements is less than sterilized substrates?

Give mixing the two a try. Shredded straw supplemented with supplemented sawdust, or vice verse. Toss some wood chips in there too. It'd be like eating at the Golden Coral for the mycelium.

Two ideas on this: 1. Lime brings the ph of the actual substrate to a level more suited for mushroom production. Also gives some calcium
2. Cooking in hot water is breaking down nutrients in the straw. Think of a compost pile...the hotter the pile, the more nutrient (especially nitrogen) lost to the air. Lime treated sub only loses what is leached out in the water

We have also been experimenting with SRA on lime straw and Shittake straw on lime straw. We have also had great success with bigger flushes and overall yield by adding well rotted manure to the lime soak water. It has no effect on contam. In fact, we have run about 50 buckets at this point and had zero contamination including ones where we used slightly moldy spawn to inoculate. What has not worked for us is using sawdust spawn. It just sits there and never colonizes the straw. Glad to see yalls results on sawdust. we are going to try this soon. Keep it up. A woman came in the store today and asked if we ever "experimented". I laughted and told her that growing mushrooms WAS a great big experiment.

bummer. it works great for us, except yellow oyster. we use a ridiculous spawn rate though- 5 or 6 lb block for a 60lb straw log- 30%.

I have several batches of shiitake on a mix of lime sawdust/lime soaked rice hulls that are colonizing very well. All spawned with sawdust at about 12% wet weight. They are supplemented at 10% with cotton seed meal. I also made a batch yesterday with just lime pellets, much in the same fashion Aleon described for his later projects. I mix water, lime, gypsum, and supplement together then added to the pellets and mixed. Once mixed I add the spawn and mix until incorporated. I also have made a few batches this way with king oyster, using grain spawn and different supplements at different rates. I have been having very good success with my mixes of rice hulls and pellets as well as just supplemented pellets. As soon as I figure out how to post an excel file ill share my data so far with some pics I have been taking.

OICU- The shiitake are browning up. At this rate, they should be ready in april sometime.
Chef- Im excited to see the yeild on your supplemented lime subs.

Let us know how the straw goes for those 2. Thanks for the tip with manure; how much are you adding again? What are your thoughts on using bagged/dried chicken manure? Sawdust span never worked well for us either with straw; when we tried years ago. But for sup. sawdust, sawdust spawn is my favorite!

Well here it is. I don't computer very well so this is the best I can do for now. I'm not sure why it changed the format? Didn't feel like paying for a dropbucket account......
Basically, and these results have yet to be reproduced, but the 5% corn gluten and soy meal at 10% and 15% gave the best first flush yields. The ones without numbers contaminated. Its been hard to really get consistent results as my grow space is very limited. I couldn't even fruit all 16 blocks to get a good judge of speed of fruiting. But all in all the results have been promising for such little effort. And the idea of mixing up a batch to make 100 blocks at a time with no cook time involved with decent yields may be worth it.
Ps- sorry for the recipe in metric and yields in ounces. Old habits.

Great for home growing. Although, those yields are too low for commercial viability; and at the extremely high spawn rates your using. Lower yields (by .25lb-.75lb/block) and 4-8 times the amount of spawn i normally use does not sound like a good alternative to heat sterilization; but i do see progress! Keep experimenting, as you may find that golden ticket

Amount of manure? shit... if varies. it doesnt seem to matter what kind either, so long as it is well rotted. we have used rabbit and horse. havent tried chicken. pelletized chicken might be a bit too rich compared to what we are using though so go easy. do a test run.

Here is one of the bags of rice hulls and wood pellets with 15% cotton seed meal. The rice hulls were lime soaked for 16 hers, drained then wood pellets added to absorbs excess moisture, and hydrated to field capacity with additional lime water, cotton seed meal, and gypsum slurry. This bag weighed about 6# 2oz. The bottom 1/4 didn't colonize due to too much moisture. This cluster was harvested yesterday from the outdoor greenhouse and weighed 1# 4oz. Always amazing the difference environment makes. These are the same species I'm also growing in the basement greenhouse.

Cute kid 
Nice work! How much spawn and strain did you use? And are rice hulls used as a supplement or as a base substrate?

Be really keen to hear an update on this if possible Aleon as I'm just starting out something similar.
One other question: How clean is your cement mixer? Do you clean it out/bleach it?
Thanks
