Blue Oyster basement farm

Hey guys, long time lurkers here ready to show off what we managed to build over the last 6 months thanks to your knowledge and positive attitude! We're open to all comments, critiques and questions 
 Right now we have a 10'x 13' (2m x 3m) space in our basement dedicated to growing blue oysters.
 Our farm produces ~30lb (15kg) a week with half going to a local CSA and the the rest to the farmers market.
 We use 8" diameter bags that are stuffed at a 1:8 wet ratio of rye and coffee grinds with a hydrated lime 3 day soak of organic local straw. To reduce back strain we're stuffing 26" columns weighing in at a total of ~10lb (5kg).
 Straw is shredded with a leaf blower/mulcher.
 Each bag produces about 2.5lb over the course of 3 flushes, with a 21 day delay between inoculation to first flush. The bucket above has been producing for almost 4 months!
 We use a large pond fogger (which I don't recommend) and a dedicated HRV for climate control and supplement heat with a inline duct heater during the winter months.
 Our current plans are to double in sq.ft. size over the next month and hopefully reach +75lb/week production.
Thanks for reading!

op, so you say you don't recommend the fogger unit? what were the issues?
ive used them in the past pumped into smaller green houses that worked well. but the clean air is forced into the humidified air and pushed into the green houses. a mixing box was used. ive seen larger setups with mixing boxes using a squirrel cage fan.

After first flush I'd say 7-10 days, later flushes add about 4-5 days extra, ie: second about 2 weeks after the first and maybe 2.5 weeks after that flush for a third.

Depending on your ceiling height you could probably get a at least 10lbs a week easily from that space! Good luck, we'll try to keep the updates coming!

The fogger heads clog too easily, and eventually jiggle themselves loose enough to allow water down into the mechanism, shorting out the disc vibrator head. We're on our second head unit and after dropping $250 I expected something more. We're looking at a farmtek fogger.
I'm realising now I should have replied to you guys all in one comment rather than spamming this thread 3 times. Won't happen again!
Thanks for all the replies!

This can be remedied by tightening up the disks every few weeks. I typically do monthly maint on my foggers and humidifier. I wipe them down with a clean wet paper towel tighten them and clean my humidifier with soap and 10% bleach. The discs also have to be replaced every couple months for proper output. They are definitely not maintenance free.

You should check out the Minifogger. I'm using the larger Hyrofogger and I've been very happy with it.

We're looking at those as well and are now leaning towards a domestic mist irrigation system.
The first thing we need to do is get the BE higher, any thread suggestions?

I would stay away from those low pressure misters. It will leave your mushrooms over-saturated and a lot of standing water. As far as the B.E. maybe try another strain or higher spawn rate.

One commercial application where i have seen the misters they sprayed downwards between the isles, so only the fine drifting mist would hit the mushrooms. A majority of the water goes directly to the floor where it will evaporate. And those foggers would only need a minute or two every few hours to keep puddling down. Some water valve timers do go down to 1-2 min increments, just not all. I would definitely integrate a filter into that mister unit to reduce clogged nozzles.

Have you been supplementing your straw at all? If you haven't, possibly look into sourcing some horse poo and try 10-20% for bigger yeilds in the same space.

So this is where the cool kids share their edible secrets. Very nice setup 
I've been looking into buying a fogger for myself and was trying to decide between the 3 and 5 disk unit. A misting setup doesn't seem practical for my small setup and my store bought humidifier has to be refilled too often.
I found a cheap source for sawdust, have you tried sawdust bags vs straw logs? I'd think you could pack more of em into the same amount of space for higher total yields.

I read the best is to use a brass nozzle mister with a high psi pre-pump to get the mist as fine as possible. Right now we get condensation using the ultrasonic so I'm not too worried about a little water on the floor.
Our water is pre-filtered with a 10 micron whole home filter, which is great for no sediment clogging but bad for bacterial growth since the chlorine is removed.

We're going for certified organic, so the fewer ingredients in our mix the easier it is. Right now we're using, organic rye and coffee as our grain spawn into organic lime soaked straw. We're hoping our gypsum experiments will bare more fruit. Does the hpoo need to be sterilized or just pasteurized?

Everything I've read says sawdust is better, we use straw because our farmer grows all organic and most commercial sawdust trees here a heavily sprayed with insecticides and herbicides.

Horse, cow, or chicken poo only needs to be pasteurized but heat pasteurized not lime. Once thing with adding poo is you need to watch your colonization temps as they will be higher with all the nitrogen. If you're really trying to be "green" and "organic" lime pasteurization is not good for the environment especially on large scale. You have a lot of toxic runoff in the form of high PH water. All that water eventually returns to the ground via a sewer plant or cesspool. Have you considered going to hot water bath? If you have a hot water heater that goes to 150-160 that should be all you need for a heat source, and ifs its an on demand style even better! Otherwise you would need a hot water heater element in your tank to bump up the temp.

Not that using lime is environmentally friendly in all ways - but, there should be no runoff from lime use. Do not soak and drain. use only the lime that you need and only hydrate your substrate. works perfect every time and is also a more consistent method. Not positive about the teks but if I find and when I find them I will post them here for all.

I'm only just now starting to experiment with straw logs and such so I'll probably start by using a hot water bath to play with small batches.
At what scale does lime pasteurization become economical? The fuel savings from not using my stove/propane burner would be nice.

That is all dependant on your fuel, electric, and lime cost. I can tell you electricity is typically much cheaper especially vs propane. Natural gas and electric are pretty close in cost but electric is more efficient at transferring heat to the water.. To heat 45 gal of water to temp it costs me less than a dollar in electricity per batch. 1500w for 5 hrs starting at room temp.

I have a 15gal keggle I used for brewing I'm considering re-purposing for a hot water soak. It has a 1500w hot water heater element and takes 1.5 hours to reach pasteurizing temp. Is it really worth switching from lime to hot water, or just wait and jump to steam when the money starts rolling in :P

I have very limited experience with it. It has worked for me - but I have only done it a couple of times. Here is a discussion that you will enjoy.

Another thing... When you use this method you are not pasteurizing like the typical heat pasteurization. It works by raising the PH high enough that no spores or bacteria can grow. At the same time mycelium seems to have no issue colonizing high PH(12). It is also a good idea to use a higher spawn ratio so that the substrate gets colonized relatively quickly - before the PH drops back down and opens up a window for contams. I hope this makes sense!

I've done a couple pasteurizations in my 15.5 gal brew kettle, good for about 10 gals of substrate. I've since hooked up a 1500w element in a 55 gal drum and insulated it for 30-35 gals of substrate. I get 1 degree per 5 min with 40-45 gals with 98F+ ambient temps, takes less than two hours to get to temp when i use hot water out the tap to start.

I was wondering about this. Where I live in New England, soil pH is generally low because of geological deficiencies and acid rain. Home owners typically apply several bags of lime in the fall to raise pH to more suitable levels. I forget the exact coverage rate, but it's on the order of several 40 pound bags per acre. It doesn't take much lime for pasteurization, does it? A few pounds I read? Doesn't seem like it would have much effect.

Btw, I'm finding a propane burner to be quite efficient. I have a 185k BTU jet burner underneath a 55 gallon metal drum. One 20 pound propane tank (17 dollars per fill) lasted me enough to bring the water up to 155, and then maintain it for an hour, on three occasions. 95% of the fuel is used bringing the water up to temperature. After that point, the burner can be dampened to a very low flame.
I just built a wire basket so that I can remove straw while keeping the hot water in the barrel. So I only need to heat it up once. I should be able to get 5+ bales done on one cylinder full of fuel.

We also run a basement farm with oysters, but using straw and coffee grounds. We make own spawn on barley from spores. As you can see, we couldn't make up our mind what size, shape and filter type should the bags have. 
We switched too recently to rehydrating straw with lime water instead of soaking, so we better control moisture content. For coffee grounds, we simply mix it with lime, gypsum and spawn, and add dry pellets to absorb excess moisture.

Nice! What's your spawn to straw ratio, those look like some big clusters!? I'm curious about your choice of using filter bags, did you get a awesome deal on them to make it cost effective versus poly tubing? I've seen some major operations (the San Fran guy) who uses solely filter bags but I assumed he bought in bulk to make it worth while.

Thanks, should we make a basement farm photos thread We used 25% spawn rate. Coffee grounds and pellet are much less voluminous than straw for the same weight, that's why the clusters looks big compared to the bags. We use PP bags with tyvek (from a painting suit) filter we make ourselves , it's very cheap (about 5-10 cent the bag), we mostly use it when sterilizing substrate in pressure cooker. We also use bags with polyfill and bags with punched holes. So far, each solution has pro and cons, now we try to perfect punched holes bags.
