Ya me to that's why I'm eager to do it I'm actually just started synthetics grow nutes and have synthetics bloom for later I wanna do some micro supplements side by side to see how much of what does what so I have on the way(next week) Barney's pineapple chunk, Barney's tangerine dream, Barney's liberty haze, Mandalas Satori, ghs super lemon haze, delicious seeds carmello,and 10 freebies from the bank lol so 2k in and I'm ready to set up n run... I've got 8x16 decided into two with space on both ends for working around, cuttings prep etc I've got 4 1k light systems w.cool tubes 50' 6" duct, two tees I'm gonna do negative pressure by way of forced exhaust through the lights with a "T" aimed down into each room to pull air and scent, pulling from an outside vent to pull in my 30° f air across the lights to cool, on a 620cfm with controller to maintain desired temps, into a square 6x8 carbon filter fitted into a register boot out of the room and into the furnaces intake duct!! Save on heat!! I got #50 co2 tank with regulator, and controller 100' hose for dispersion I got 4- 5x4 table frames with screens for scrog and covers if I wanna use them for sog instead, timers surge strips etc 4 oscillating fans, enough panda to line everything and device rooms a greenhouse for germination and cutting that will go in the vanity from my earlier set up, the only thing I still haven't figured out is how I will share the air between the two decided rooms without letting light in!!! Because I don't wanna run separate co2 vents blah blah blah in each area!!! Any suggestions!? I had considered the staggered box thing but I want decent air transfer between rooms but without letting light over and I don't think a little square of air will be enough... but ya I'm getting ready to start building tomorrow!!
