Experiments with fine furniture sawdust as fruiting substrate
#20967711 - 12/12/14 05:04 PM (9 years, 5 months ago) |

Hey folks,
I'm curious if anyone's got any recipes for furniture sawdust (alder and oak) as a substrate for edibles/medicinals. Furniture sawdust is very fine with some wood shavings in it and a lot of dust. For that reason, I'm experimenting with adding coarse vermiculite to prevent compaction and poor colonization. I'm also making small substrate bags to make sure they colonize all the way through, at least this time until I'm sure the substrate will work.
I've got some grain spawn ready of several Ganoderma, L. edodes, and Pleurotus cultures that I'm running on different recipes. I'm pasteurizing some mixed with 50% coarse verm and others mixed with only 10% verm. I'm sterilizing some with no verm and no N supplement (for L. edodes), and others with 10% verm and oat bran. Finally, I'm adding some pine woodchips to the recipe for one bag of Ganoderma resinaceum. I don't have reliable access to mill sawdust and woodchips that are not pine. I'm using high inoculation rates for all combinations. All will get a small handful of gypsum.
Does anyone use furniture sawdust? What have your results been? Do you have any advice for me? I'll update this thread as my experiment progresses.
Thanks!

nobody's growing on furniture sawdust? seems like a fairly abundant resource around my area...

I've been using a mix of fine sawdust and shavings at 2 parts fine and three parts shavings. The shavings are like pet bedding but they came from a place that makes wood moldings.

from what I've read on this site, most people seem to be using a much more coarse media than fine dust. Chips seem to be preferred and one of the guru's of this site has suggested chainsaw shavings as the finer end of the spectrum

Never tried it but I think coarse verm is a good idea. I ought to see if I can find a place like that near me but I think they are hard to find here.

thanks for the feedback, guys. i really appreciate it. if there aren't many people using it, I'll definitely report my findings with pictures and whatnot. Since I can't find anything on the search function.

the sawdust i get has probably 10-20% shavings in it. every once in a while there is a chip zied piece. i'll take a photo of the mix

Last night I mixed up some experimental substrate that I plan to noc up with my G. resinaceum wbs spawn. Here's what I did:
8 1/2 cups dry volume of furniture sawdust (hardwood)

5 cups dry volume aged pine woodchips

1 cup dry volume aged pine sawdust

1/2 cup oat bran
1/8 cup gypsum
3 1/2 cups hot water into sawdust/bran/gypsum
soaked chips in boiling water 1/2 hour (they were already wet from snow)
Each recipe fills one unicorn 3T filter patch bag. Sterilize at 15psi for 2 hours.

I'll spawn them tomorrow, I have more substrate to make today and that gives them ample time to cool. We'll see what happens.
I'm also planning another recipe for my shiitake. Something along the lines of 50% furniture sawdust, 50% coarse vermiculite, with a handful of gypsum and a handful of oat bran. I have to go buy more verm, first, though.

Today I made some pasteurized substrate bags with the furniture sawdust. I mixed some 50/50 with coarse vermiculite and pasteurized btwn 170 and 180 for 1 hour. Then, I inoculated the substrate with a quart each bag of 1. Pleurotus ostreatus var. columbinus; 2. Pleurotus ostreatus wbs spawn.
I also mixed some furniture sawdust with pine wood chips and pine sawdust just like the recipe above but pasteurized it instead of sterilizing it. I noc'd it up with a quart of G. resinaceum wbs spawn.
More pictures to come....

Sorry to keep posting on my own thread. I just found a potential perfect solution to my problem. Someone directed me to this thread:
http://www.shroomery.org/forums/showflat.php/Number/13497853/fpart/4/vc/1#13497853
in which, RR and a few others mention they had good luck using sawdust and straw 50/50.
the straw may serve to prevent compaction of the fine dust. Since my dust is so fine, i'm going to try adding it to straw at different ratios less than 50% until I find the optimal combination for the strains I have. I'm currently cultivating shiitake s75, 3870, and TS1. I also have wild cultured G. resinaceum and a G. lucidum from spore depot. I also have a few oyster cultures I'm cultivating, P. ostreatus columbinus, a gray oyster (p ostreatus) and a wild oyster I cloned. I'm going to try the straw/sawdust experiment next time its nice out. Its currently snowing....
I'm hoping the pine sawdust and wood chips recipe posted above will work for the G. resinaceum. I also spawned a bag of that recipe with the 3870 shiitake. But more options are good. I have unlimited access to pine sawdust and wood chips but straw is easy to get, too. Its the hardwood sawdust that is hard to find.
I hope this information is able to help some other people. The thread is serving as a space for me to collect my thoughts and record my experiments, as well. Thanks, shroomery!

Your picture of the furniture sawdust looks almost like the mixture ratio I use. I'm sure by itself it would still be less compact then using fuel pellets which still work well.

Oh, good! I'm happy to hear that, Yappi...we'll see how it goes. some of my bags are on day 5 of colonization and they look fine. It would be great if I could use that sawdust mix without adding verm because the sawdust is free and verm isn't the cheapest stuff...

These are the bags i sterilized in my experiment. the two on the left are the furniture dust and pine chips recipe, the two on the right are 50/50 furniture dust and coarse verm.
If you were to number them from left to right 1, 2, 3, 4, numbers 1 and 3 are the same culture, shiitake 3780. 2 is Ganoderma resinaceum, 4 is an unknown L. edodes culture from a trade. They were noc'd up on 12/17.

here's some of the pasteurized furniture sawdust bags with pine spawned on the same day.

i also made up some furniture dust and verm bags and noc'd them up with oyster grain spawn 10 days ago. i'm having trouble keeping the temps up since its getting down to 10 degrees F at night now and some are beginning to pin already. its a little too soon but they're almost fully colonized. that's 10 days from spawning. we'll see if the bags spawned on 12/17 catch up.... [edit: that's 10 degrees outside, my room's min temp is around 65, i want it at 70]

my current incubation space is in the indoor garden. warmest spot in the house

This is really cool, Niki- thanks for sharing. I don't have consistent access to good sawdust and based on my resources and climate, it's hard to grow certain species here (too hot). I'm looking forward to trying shiitake 75 on 50/50 straw/sawdust mix, too.
Lol we have opposite problems when it comes to climate.

haha, yup. temps pretty moderate here but its way dry.
i had an issue with trich on my pasteurized bags. i punched holes in them for air exchange and around the holes there are colonies of trich growing. very sad. i lost 4 bags so far, out of about 10. my guess is the spores are just in the air because i keep them in the same room as my indoor garden. its the only space in the house that is warm enough for my fungi. i think next time i'll put micropore tape or tyvek over the air exchange holes after i pasteurize and see if there is an improvement. my sterilized bags are doing great. especially the G. resinaceum on furniture dust and pine chips. its already fully colonized! just gotta clean the fruiting chamber, then i'll put it in there.
hope everyone had a wonderful solstice, festivus, hanukkah, christmas, etc. don't drink and drive. peace

I notice that my sawdust blocks will contaminate around gas exchange holes if I have over pasteurized the sub. If you're soaking in boiling water I would imagine that the sub is getting too hot, 180 is the max temp for pasteurizing imo.

I thought that might have been the case, too. it was all one pasteurization batch that contam'd. and i was guessing at the temps because i broke my thermometer last month and hadn't yet replaced it (i got one now). weird that wood will contaminate. you wouldnt think so.
thanks for the input
