How to Make your own Oyster Mushroom Grow Blocks WITHOUT Sterilization

- Typically mushroom grow blocks are grown out onto a sterilized sawdust substrate in a clean, controlled environment. However, you can make your own blocks at home with this low-tech method, bypassing sterilization and still getting some impressive results!
***UPDATE: we have now trialed this kit with other Oyster varieties and it is now available in Golden Oyster!

Psychedelics saved me from years of uncontrollable depression, anxiety and illicit pill addiction. Imagine carrying heavy chains for over a decade and then all of a sudden that burden is gone. Believe it or not in a couple years they'll be all over for treatment of mental health related issues.
Please does anyone know where I can get them? I put so much on my plate and it really affects my stress and anxiety levels, I would love to try shrooms
I was having this unbearable anxiety and depression because of mental stress from school, work and life generally. Then I came across a mycologist dr.joeshroom He saved my life honestly.

I find that setting my stovetop burner on medium-low with a stainless steel pot full of water results in temps from 166 - 178F, perfect pasteurization temps. Throw your substrate in a cheesecloth bag and throw it in the pot or an hour.
My left ear enjoyed this
Very useful, thank you!🤗
I've found that sourcing soybean hulls and cottonseed hulls can be quite challenging and expensive for most people, especially if they're not buying in bulk. Do you have any recommendations for more accessible and pasteuriz-able alternatives for sawdust supplementation? Thanks!
I would maybe look online for "masters mix" which is just fuel pellets and soy hull pellets, but there are companies out there that sell them pre-mixed. We use grain and molasses as supplements for certain species, but I would say for oysters the best bet would be to purchase a "masters mix".
Great vid. (Although audio only played through the left side)
Thanks for another interesting and practical video!
Do you know of any source for organic cottonseed hull pellets or organic soy hull pellets? I would buy them from ff if you offered them.
Great Video !~~any tidbits on keeping spawn in the dark for those 20 days or is ithat not necessary?
It's not necessary! The blocks can be kept in the dark if you choose, but indirect light is also fine.
Can this be done in containers other than disposable plastic bags? Can you use these pellets in a bucket, or is that too big for something this dense?
You can use buckets, but I would suggest going with something no larger than a gallon. The biggest hurdle you run into is mimicking a filter patch so that the mycelium can breathe.
Could i just skip the pellets and use aspen wood chips instead?
I can't say for sure as I haven't tried it, but I don't see why that would work. I would likely be less productive as there is less substance, but it should still produce mushrooms.
How do you store the grain spawn and substrate materials if you want to do consecutive plantings a couple weeks apart for each block?
The substrate can be stored dry, but the grain spawn should be resealed and stored in a refrigerator. Unless it's pink oyster- pink oyster needs to be used once opened. Keep in mind that once grain spawn is opened it does increase the risk of contamination as it has been exposed to airborne contaminants.
Any tips for finding pelletized cottonseed hulls? Or would non-pelletized cottonseed hulls be okay to use?
We buy them in bulk, but if you do a quick online search there are a few sources that come up!
it looks like my pohu oysters have spawned in less than a week . there are some big white mounds about 1"or so.. should I roll up the bags now to finish the process?
Wow! That was fast. Yes, roll up the bag and finish the process!
Thanks for this! I grew your pink oysters in bags inside, and since I have quite a few acres I put them outside when they seemed 'done'. They flushed again though not as strongly. Will they survive a 6b winter, and if so can I give them anything to get going again in spring?
Oh, and, what can I do to get mushrooms to take over my forest :D (Unless that's an 8-hour per day project, haha)
@@rambunctiousmrsraines Try a patch of wine caps...and grow on from there
I second what Christina said! Start with Wine Cap. You'll eventually want to inoculate logs as logs last quite a bit longer than any bed mushroom.
@@FieldandForestProducts Thanks. Would adding chips to the wine cap bed I started help them come back? What time of year, how much?
@@rambunctiousmrsraines I have found that adding fresh wood chips to winecap beds will feed the mycelium and the bed will continue to produce mushrooms although they might pop up in different locations. It may help to find the colonized woodchips from the previous inoculation and relocate some with the new fresh wood chips. This way you can maintain your beds for many years.
Greetings from New Hampshire. In an effort to reduce the carbon footprint of mushroom cultivation through the use of plastic bags, are there other containers that could be used for non-sterile cultivation, and if so, could you do a video on how? Thanks
Yes excellent question! The biggest hurdle is the need for the filter patch, but we're experimenting right now with upcycled containers. Once we have it figured out we'll definitely be sharing!
@@FieldandForestProducts I have tried a using a bucket with 1/4" holes drilled in it with limited success. I am going to increase the hole size to 1/2" and use micropore tape for colonization phase the remove it for fruiting.
@@lambbrookfarm4528 Keep us updated! We're trying with smaller containers (like yogurt containers. So we'll see where it goes!
I made 20 bags like this using 50/50 soy hulls and hardwood fuel pellets. Every single one fruited great. Zero contam
OK, but why not sterilize? When I did this with Lion’s Mane, I saw green mold contamination during incubation. It went away and the mushrooms were yummy and healthy. But U-Tube has plenty of videos on sterilization of grow blocks. If you don’t have a pressure cooker you might have an Insta-pot. Next time I’ll try that.
Sterilizing will definitely allow you to stretch your spawn further, but if you don't have a pressure cooker or instantpot this is an easy alternative.

Unfortunately the audio was recorded in a mono-audio format - you'll need to use both channels of audio if it's not coming through.
