I'm looking to set my grow room to an optimal CO2 ppm. What ppm do you set your grow room to and could you tell me the difference in yield when you didn't have one?

1500-1800ppm i usualy float around 1675. Anything above 2100 is toxic to your plants bout a 17%-22% increase tested on a SOG. Make sure your grow op is dialed in first lights,temps,humidity etc... Other wise co2 is kinda a waste IMO.

SInce its a SOG i only do budding so i keep it at 35% sometimes a little lower, Temp 84-86 85 is ideal but i dont mind it drifting a little. Running a 400watt on the first table not to light shock them since i do Clone to budding there only bout 9"-11" tall then a 600 above the 2nd table 1000watt above the 3rd. I do harvests every 3 weeks.

Dam i dont usually get wowed by a grow op but dam that ingenious. I like to keep it simple tho 7+ years with hydro and i learned the simpler you keep it less shit can go wrong and when it can go wrong oh you better bets your ass it will :-D so a fill and drain sog is awesome in yield thank to the perpetual harvest 1.9-2.2lb every 3 weeks. You grow top cola only so the bag appeal is awesome nice giant rock sold nugs. Not to much trimming 25 of my plants takes maybe 4 hours. BEarly anything go wrong a pump might break $15 at the local hydro store. but the way i have my pot's set up they can go with out being watered 2-3 days. I check on em everyday as well so not to worried.
Check this out mine looks almost identical to this one cept im running 3 trays hes running 4 trays.
