Nolan's gonna be a genius! Taking it all in, those are curious eyes right there.

I haven't found a good economical supplier for soybean hulls, and I'm just a hobbyist so I've been experimenting. I use whole corn for grain spawn because its easy to get and cheap here; so I tried just adding 15% rinsed whole corn to my bulk substrate (hardwood pellets & gypsum) and it works pretty well as a nitrogen supplement. I didn't notice any more contamination in my bags than wood + soybean hull. I pressure cook the substrate for 2.5 hrs at 15psi prior to inoculating. The highest percentage of corn I've added to a bag is ~%30 and it colonized fine and fruited.

For something that is really trash and would be hard to get rid of it certainly is very expensive at least in Pennsylvania ....

I'm curious about cornmeal substitute for soy, but using oat spawn

Picked up a chestnut culture from 3F a few weeks back. Just put it to grain two days ago and wow is it an aggressive culture. Looking forward to trying out more!

[@weed_monster_grows]

Thanks for sharing the information as always great job ❤❤❤🎉🎉🎉🎉🎉🎉

I grow a lot of mushrooms in just straight cattle corn. Pressure cook them until they start getting soft but not mushy and do a run of straight corn. Try the oysters.

[@DrowSkinned]

it's so pretty out there. Makes me wish i could move out there.

[@yoyofd]

question . let’s say my mushrooms started pinning and i need to go take a plane and be out for 2 weeks . can i put it in the fridge while i come back and place it back to fruiting as soon as i get home ?

[@SirBoden]

Other than changing the carbon / nitrogen ratio a minuscule amount, I can’t imagine how having bits of corn in there would matter.

[@FreshfromtheFarmFungi]

some people claim they carry more contam loads

[@davidmartnick7195]

​@@FreshfromtheFarmFungiI used corn and wheat for my AIO bags with master's mix. I had approximately one bag contaminated in 300. I don't think there is any legitimate premise to this experiment. If you are looking for a solid experiment for your channel, can you look into caramelization of grain spawn inhibiting growth of mycelium? I have personally been seeing that some of my AIO bags are not becoming inoculated from the LC in bags that have caramelized.

[@tdtrecordsmusic]

maybe whole kernels that would need a longer time @ higher temp to fully penetrate a thick dry corn grain... I've never heard this myth btw

[@thematrixcentre]

Can we used mixed sawdust, (from different wood) for growing oyster mushroom. And what % of supplement in the substrate to be pasteurize not sterilize.

[@FreshfromtheFarmFungi]

yes I began this way - watch this video kzbin.info/www/bejne/bpCvcmR_arR_hZosi=7JBEQoaPZ8FrmV7c

[@pain_lamo3022]

This question isn’t really related to the video but how do you get mycelium onto agar plates? I tried looking it up but nothing answered my question, hopefully you’ll be able to!

[@FreshfromtheFarmFungi]

there are many ways check out this video - kzbin.info/www/bejne/r4umnXV4jd-IqLMsi=A4VmtgtlgFO0AKIi

[@reidnorton6794]

I just watched your video about isolating a single spore...Do you have a video about what you do with it afterwards? Thanks

[@FreshfromtheFarmFungi]

yes check out our breeding projects - here is the next step kzbin.info/www/bejne/sIGwkqiEnsaboKMsi=ExdV2UiRRahKXezt

That grin at 7:06 haha

[@alansarthou3276]

Have you ever tried doing those cooked mycelium bricks that have amazing thermal insulating properties? Just a curiosity, but I'd love to try that 😅

[@FreshfromtheFarmFungi]

Ive seen them at telluride but never manufactured them

[@willit007]

So beautifull!!!

[@Superfluous123]

Is Master’s Mix supposed to be pasteurized or sterilized??

[@FreshfromtheFarmFungi]

I use an atmospheric pasteurizer and it works great - not perfect but well enough at this altitude

[@mikearts6836]

Hey gary what happen to the air science hood?

[@FreshfromtheFarmFungi]

it’s still in my building in storage waiting for the new lab to get it up and going - we are moving slowly but surely on that

[@mikearts6836]

@@FreshfromtheFarmFungi - I am considering buying one i just wanted to make sure it will work well . What do you like better the wall you have now or the air science?

[@SirBoden]

I can imagine someone will give you grief for using oysters as they will eat damn near anything. 🤓

[@FreshfromtheFarmFungi]

I also threw in a bear’s head which can be finicky

[@triple_gem_shining]

🔥🔥🔥

[@noqsw5058]

Try Jerusalem Artichoke

[@tensiondriven]

I bet you could time how long it takes to fill those two steel water containers, and then fill the bags directly from the hose with the use of a stopwatch… save some time

[@FreshfromtheFarmFungi]

yes 👍 they also make volumetric baggers now that automate this
