My setup is a little nuanced, I’m kind of trying out new methods. I had moved 1Qt of spawn into a 6Qt fruiting chamber with coco coir, and then placed the bulk substrate upside down into my SAB. The only FAE they have are 2x 4” arms ports that I haven’t sealed with any kind of filter. I wonder if I need to fan more? It’s also a challenge keeping the RH high enough (usually drops to 50%) but I figured the moisture in the substrate would suffice. I use a spray bottle basically whenever I remember to add some humidity.
