the screen looks to be just what you needed in there. nice.

why are you wanting to top at 10in and why do you want to top, supercrop and scrog all at the same time? i would flip to flower at or before 10in and top early on in veg. but i think i just said all this the other day.
the topping, SC and scrog are all different methods to achieve the same results (keeping the plants low and wide) and really, unless you dont plan the height of your plants well, you really never need to SC and scrog at the same time. topping is effective with both SC and scrog.

is there a reason for wanting to use 2 plants and not 5 or 6? the law? to fill the tray with 2 plants youre looking at about a 4 week veg or more and with 6 plants maybe a 10 day/2week veg. a longer veg will effect the flower time. the yield is set by the lumans. so with the same light you will yield the same amount but in just about 3+ weeks less time. that also saves money in power bills. but it seems like you have your mind made up so this will be the last advise i give on this issue.

not sure of the temp and humi in your room but i was up to 85f and 25% the other day with all fans and venting on. i just went and bought a swamp cooler and yesterday it was 94f and dry outside where im at. lights came on at 8pm and with the swamp cooler it was 80f and 60%. there is no ducting and it runs on about 300watts. love it. today is going to be 101 where im at...
