I'm new to mushroom cultivation and don't own a pressure cooker. Would it be OK to bake the jars in the oven at around 200 degrees to sterilize the substrate?

Invest in a Pressure Cooker it is manditory I got a 100% success my first grow all cuase I bought that 100$ PC buy buy buy IT boiling your jars and sticking them in your oven wont work. Putting them in the oven they will dry out and the jars will proably crack and it doesnt strelize it good peace and good luck

No, this will dry out the substrate making it useless for cultivation. Also, 200 degrees (F) is not hot enough to sterilize much of anything and 200 degrees (C) is too hot and will carmalize most sugars.

I read in one of the tek's that you can boil the jars in a pot with the lid on for like two hours and it might also work. Does anybody know if this technique is also bad?

This is how I began. I put it on med/low boil for around an hour with the lid on. Out of 10 jars (7 1/2 pint and 3 1 pint jars) I didnt lose one jar. However my house is extrememly clean. I dont think it would've worked so good in some houses around me.

Boiling your jars is risky business. Invest in a pressure cooker. It is well worth the money. It will pay for itself over and over again.

ive been told that w/ the pf tek a pressure cooker is not neccisary. ive done it both ways w/ pressure cooking and boiling. both ways i had clean and contaminated. its just the matter of chance. you don't need a pressure cooker. so fuck all them that think its manditory. cuz it isn't. its just more likely to work better. thats all. its psycological. you THINK its better w/ the pc cuz everyone says it is. if you have one, use it. if you don't fuck it. only if you're harcore into this hobby, then fork out the money to get one. but it aint neccissary. good luck.

yea im pretty sure its just with the PF tek. Ive tried other methods like rye and failed miserably. Things like that require a pc. But you probably shouldnt try routes like that untill your experienced.

afof used the pftek and boiled jars 1 hour each, never got anything below three solid flushes before seeing anything green, and never lost a jar to contams. works fine as long as you stick with brf and verm if you move to grain you need the pressure though. he has moved on now but for starters it works just fine, baking though I don't think is a good idea. in the long run I would suggest buying a pressure cooker but believe you me you can grow a good bunch of mush without one.

ya, i started by boiling it worked great out of 12 jars i only lost 1 to contams.

but pressure cooking is the way to go, i bought one at wally-mart for 20 bucks!!!

it only holds 5 jars but who cares it gets the job done and one thing you need in this hobby is patience
having a litle extra work to do is better than sitting there staring at your jars everyday waiting for them to colonize
it gives you more stuff to do... so have fun

The shrewmen are on their second batch of cakes and still don't have a pc. Boiling is fine as long as you do it right. Have a large pot with a tight fitting lid. Make sure you have a grill or dishrag under the jars so they don't directly touch the bottom of the pot, or they could crack. Fill with water about halfway up the jars. Bring to a boil, then cover and boil for an hour. Allow the jars to cool completely before removing the lid. To further lessen chances of contam, bake the verm and brf on seperate baking sheets for 2O minutes at 35O before mixing. If you plan on using whole grains you'll need a pc, but for verm/brf this works just fine.
