I couldn't decide where to put this post - it's mostly a general sterilization question about PCing bag spawn. I remember reading recently that bag spawn has to be sterilized for considerably longer than jar spawn. I'm assuming you've just got to have considerably more water than usual?
I'm also a little concerned about the gas required to PC bags for hours on the stove. I'm thinking about creating a solar collector and heating up the PC that way. I've seen some pictures - seems slick. So this is pretty related to the other thread I just posted about a solar oven for pasteurization.
Maybe the right answer is to get the biggest AA PC I can find ( I guess that's the 941 - 41 qts) and running an outdoor burner. With the help of the sun, probably wouldn't require a lot of gas.
Sure would like to have an actual autoclave - has anyone ever priced them? Are they even buyable as general population?
