dual cool tube

[Markers]

Just another cool tube idea.

very interesting I think that will work quite well for you. however you will have to put a carbon filter on the output side of your exaust to take up the odor within the grow space.

How do you adjust the light height ?

I like it! I think that you get a lot better cooling when you connect your ventilation like that.

In my flowering space, I do not really move my lights up and down, but move the plants and keep the light pretty stationary.
