So I have 3 trays in my fruiting chamber right now, but i'm gonna be gone for about 5 days. I am using a 10 gallon aquarium as my FC with a lid that has holes in it. The dimmensions are about 24''x10''x12''. The humidity is stable and I fan about 2 or 3 times a day. Since I am gonna be gone, will one of those aquarium air pumps work to exchange the air in there, running 24 hours? Thanks for any help.
Aquarium pump, particularly if set up to bubble air through water using a bubble stone, is a good means of air exchange, yes.
