Welcome! I have been thinking about starting a thread for my grow for awhile now so here we go. This is a perpetual grow so I kind of didn't know where to start. I guess I'll list the specs and then jump right in. Flower Room Room - 13' 6" l x 8' 6"w x 9'h single car garage concrete floor slightly sloped Lights - 2 1000 watt Eye Hortilux HPS bare bulb's hanging vertically Light Mover - Lightrail 5.0 commercial mover Intake - 8" centrifugal fan with filter Exhaust - 8"centrifugal fan on a 4' tall carbon filter Co2 - Gen1 4 burner co2 generator Controller - Sentinel CHHC-4 Cooling - 12,000btu dual hose in room portable, 5,000btu window unit Humidifier - Honeywell $50 humidifier with replaceable filter Air Circulation - 4 box fans Backdraft dampers on all hoses I finished building this room end of spring and ran it all summer with no c02 or ac. Well, I used ac for lights off but not lights on. In september I started using the co2 at 1300ppm. Room temp is 68f lights off, 86-87.5 lights on. Relative humidity is 50% lights off 60% light on. I use the dual hose ac only for lights off and the window ac only for lights on. Light mover moves about 2'. plants are about 14" away from the bulbs give or take a couple inches. I'll try to answer any questions anyone has. I'll do the veg room next.
