Nice thoughts and suggestions-- thank you coorsmikey and Jinroh
And Jinroh, as far as the quantity factor (or space optimization, specifically) I can't imagine it would be a problem to stack several of the flattened bags on top of each other, or even lay them together sideways like books on a shelf. So long as the filter patch isn't blocked, it shouldn't matter much?
I would honestly think it could be a better way to pack in many more bags/lbs per cubic foot if they were thin and flat vs. fat and brick'ly since you'd be using all the bag interior that's wasted when in it's typical form -- I may try it both ways myself--
Either way, great conversation --
I can see this method possibly reducing condensation which can be a problem if it gets out of hand. The only issue I am thinking about is flattening the bag after sterilization and inoculation. The filter patches on the cheap bags I buy do not flow very well. I assume because they are .2 micron or low quality, which seems to be common with bags. I know the better quality bags have more options related to micron rating and bag shape/size. It takes a lot of care and patience to force out the air in my bags once they are sealed and inoculated. I have broken the heat seal on them in the past doing that. I would probably eliminate most of my bag issues with better quality bags. I can't seem to find good bags that come in small quantities since the really nice bags are sold in bulk to professional mushroom farms in lots of 500 or 1000+. I guess I should just bite the bullet and buy a lot and never have to worry about it again.
