petris
Oh yeah, you could also look at the fungiperfecti website for climate control systems.
Why would you need a thousand petris though? The whole idea of agar work is to isolate productive strains and then use them for expansion of mycelial mass through grain to grain transfers...I suppose if you were doing multiple species and required a constant rotating catalog of genetics, but why not just do agar slants and keep em cold? I think the bigger issue would be where your going to find a thousand half gallon jars....
Bulk composting would probably be the most efficient way to go about this, rather than a sterile lab...agar to grain to bulk grain to compost.
