I don’t have time to do all the required air exchanges for my fruiting tub, so I worked out an automatic ventilation rig that I’m pretty happy with, and thought that I would share it with all of you.
What you see, from left to right, is a small Dirt Devil HEPA filter, taped to a 3” to 4” PVC pipe reducer, a 4” duct booster fan, a short-cycle digital timer from Amazon, a length of 4” ducting, taped to a 3” adhesive toilet seal. I attached the fan to a piece of wood with 4” tension clamps, and put anti-vibration pads on the bottom of the piece of wood.
I cut a hole in the tub + stuck on the toilet seal + piped in the reptile fogger + put the lid on = happy cakes. Timer works perfectly, blowing HEPA-filtered air into the tub for two minutes out of every ten, total cost about $60.
