Good morning, we bought a 4" inline exhaust fan, however there is not a timer on it.
Does it run all the time to keep the 1-3 minute circulation? Or do we need to find some kind of heat controlled timer? Reading your book and watching your videos but we are still confused.
Help please.
I have 2 tents and my fans stay
on all the time and it seems to work good for me. Here's some photos of my current grows.
4x4 tent growing papaya stomper photo period with 6" exhaust fan on 24/7.
3x3 tent growing gorilla glue #4 auto, critical purple auto, and Tangerine Dream auto with 4" exhaust fan running 24/7.
I am sure MGI will chime in but until then if you would like-
Did you see the video where he sets up a tent? What kind of fan did you get? Does it just have the speed controller?
I actually just replied to your YouTube comment asking this question. I'll post it here as well in case anyone reading here is wondering: 1-3 minutes is general guidance. Basically, the plant needs CO2 in order to grow so that's why the air is exchanged. If the plant is a seedling in a 4x4 grow tent for example, then the air in the environment doesn't need to be changed as often as larger plants that fill up the whole grow space. Hope that helps.
