So basically you say to sterilize in the microwave, and then do an open air, G2G transfer?

:popcorn:

I can feel the storm comming...

Please show us all the mushrooms you grow using this method.

RogerRabbit is a mycologist too. He cultivates Shitake for a living (and many others I imagine).

Open air innoculations, be it grain to grain or any other method has been tried many many times before. It is probably the number one cause of contamination.

not here to argue wildernessjunkie,this is straight from my mycologist a new and tried method,like i said wont knock it till ive tried it,was put up to help others out.
Know if you have your oven in the busiest part of the house,in the morning where the air is going to be more disturbed than settled,you would get contaminants,being clean quick and efficient is the method for your comprehension.
Thats all ive got to say on the matter take it and learn or just leave it, BYE happy shrooming.

It's not new really, people have been doing this quite a bit, and yes it does work, but the contamination ratio's are far too high to be viable for anything other than amusement.

It is cheaper to pasteurise unsupplemented subs with hot water.

I steam all my bags using a microwave, but a little differently than oz.  I put wood shavings, wood chips, straw, gypsum, and rice bran in a 50 lb polyproplyene bag (Ol' Roy bag, chicken feed bag, etc.).  After mixing the ingredients dry, I add 2 or 3 cups of water ONLY, and put bag into microwave (I add enough ingredients to fill my 17" nuker).  I cook for 5 minutes, then rotate the bag, and cook for 5 more minutes, rotate, etc., until it's cooked for 20 minutes.  I let it set in the steam for another 20 minutes... and it's sterile.  Before I add more water (10 lbs) to the steamed bag, I add a little clorox to the water to make sure it's sterile (our water is unclorinated).  I always PC my grain jars so I know they are sterile.

Now, I know there is probably some bacteria over in the Congo, or in some hospital, that steaming won't work on- but for me steaming kills everything floatin' around in my house.  The only time I've had contams is when the bag gets punctured, and I had let the bag sit in the water that came out of the hole.  I've learned to put the bag on a towel to test for punctures, then turn over if I have one.

For me, steaming in a nuker is easy, not messy, and works.  But if you add the full amount of water before steaming, it takes forever to get hot... if ever.  Just go 2 or 3 cups of water and the bag will be so steaming hot after 20 minutes that you can't touch it.  That's why I recommend those PP bags that they sell chicken feed in.  After adding the grain and water, I transfer to another bag made from tubing, and put a homemade tyvek filter on it.  Try it before deciding if it's right for you... but I make up about 2 bags a day using this process and I'll never do anything else.

Damn that sounds like a lot of work.  But whatever works for you.

No mycologist would ever recommend that. 

Anyone recommending microwave 'sterilization' followed by open air inoculation is a brand new noob.  We get posts like this nearly every day.  Just search back and you'll see them all.  If you want to succeed and not just waste time and materials, stick to proper procedure.  They've been developed over the last half century by people who actually succeed.

Each to their own. everyones got their own ways of doing things just because its not to your liking,tis tis,maybe in the past it hasnt succeeded because of their work habits ,environment,or mixtures wrong,have you guys actually tried it,or just going by other peoples word?

:facepalm:

When you can produce actual mushrooms with this dreamed-up daily fail routine, then you can defend it.  Until then, your bright idea isn't going to work. Period.

Asking us to try it is like telling a surgeon to perform open heart surgery in a garbage dump by using a used cardboard pizza box as an operating table, and until he does he can't say it won't work.  You go ahead and waste your time, but not ours. You're arguing with real mycologists here, not kids.  Sorry.
