Morthos, there is no secret to the setup I have, just lots and lots and lots of rubbermaid bins, filled to the brim with jars. I use seperate lamps overlooking the tops of the bins to give them light. Nothing to it
And the mushrooms fruit just as well in 500ml jars than in 250ml, if anything you get more out of the 500ml because they have room to grow longer and fatter. I get at LEAST 3 grams dry off of one 500ml (as opposed to 1-2 grams with 250ml), plus it will flush again.
It just takes a LONG time to make and cook 200 jars (but the process becomes much shorter with the help of four pressure cookers).
I know there is a way for better yields (straw logs, casings) but if you want bulk INIVTRO, then my method is the best way. There is only so much one can harvest from a single invitro jar, you might as well make a ton of them if you want bulk.
