I may add a second screen myself. My plants well one in particular, are a kinda big and will outgrow their area. A second screen may do the trick. I had one in my first couple grows, but found they got in the way, so I stopped, I may rethink thatCreated my access door, added the other carbon filter on the lights, and added a second trellis. I dunno if I should have, but I did lol.. Hell we might even add another lol..
Anyways time to see how much those filters heat my room up. Hopefully it's manageable.
