Heat/humidity control

I am converting a fridge in to a grow box, I have read that heat and humidity are hard to control. Is there a large enough exhaust fan that can combat this issue?750cfm? Would a secondary exhaust on a temperature/humidistat work? Any input appreciated. Pics to come!!!


Welcome to the forum

If the fridge will be your “grow room” it isn’t a very large space so I would think a 4” inline fan would be more than enough for that space.
Temps and humidity I guess would need to be controlled using the air you would be pulling into it with the ducting from the room the fridge is in and you would want to control the rooms environment I would think.
I haven’t used a fridge but I think others here have.
Use the search feature located at top right (magnifying glass) and type in your key words and you’ll be able to look through the results.

Good luck with your grow
