i don't know if a pringles bottle/jar is good enough but i do know that you can get quart jars
for reallly really really really cheap, you buy 6 a box for like +/- $10.00

i used to grow shrooms and those jars are what i used to grow the mycelium

go to wal-mart, if canning is in season they will have it. otherwise fi you ask one of the old women that work there you'll get a stupid look and a stupid answer
