Thanks for the warning on those ipower, I’ll be sure to avoid them at all costs. So, since I last posted I had to move my tent. It’s now in a cooler area (19-20C) compared to the 22C it was in. So that kinda forced my hand and I’ve equally spaced the girls across the tent with an autocob above each plant. I just finished this about 45 minutes ago so I’m going to check on them in an hour and see how they’re doing. I have the lights about as high as possible right now.4” fan would be more than enough for the space as well. 6” is a lot bigger, heavier, louder and more expensive. I’m not up to date on brands unfortunately. I traded an oz for my 2 - 10x48 fan filter combo about a year ago. Before that I just ran cheap ipower filters. They suck! The lip that’s used to connect the two or connect the ducting is smooth and tapered in the wrong direction. I did everything to secure it and still walked into 100+ degree temps when the ducting slipped off.
