I was thinking something a little bigger, like a 500 sq ft facility
Hi, i've seen someone build a breeding room with a few smaller separate chambers side by side. They were probably 2'x2'x3' each and had their exhaust air openings connected to one bigger ventilation line so there was always the same negative pressure in the chambers and nothing (pollen) would be mixed up. I thought i've seen it here but can't find the thread.
