This is fascinating! In my opinion having your exhaust fan outside is totally fine as it is still drawing air out of the top of the tent. It does the same job, just remotely!
Ahh geez Beez now you're just making me feel bad there . I wouldn't be surprised if you had many lurkers watching and following, as its an interesting topic, and you explain things very well.saying I very much appreciate my one follower and hope you stick with me till the end.
I have a hell of a lot more faith in your growing skills then mine. I've only ever had one plant get near the lights and it stopped 4 inches short of reaching them. I think this GT is headed to the top of the tent.I have faith in your growing skills and it won't be a problem!
