ok hey thanks for replying to my post so fast...I was thinking 4 lights in the 15x15 area,( was leaning on 600's) if ya think I can get 6sq out of each 1k lamp I'll be ok. I'm gonna modify the AC's return air. The "thermostat" on a ac unit works from the temps around it's return air. I plan to duct the Return Air (RA) directly into the grow room at about 6ft high, So temperatures from bulbs/ wont be a problem (no inline ducting from lamps) My Vent air is going to be a 10 inch hole cut into the ceiling of the rooms closet/roof of the house, pushed out by a separate "box" fan, but most likely a squirrell cage, I'll put a mini turbine on the roof so it dont look strange. I'll be out in the country so smell is not a problem either. Honestly bro, I've got most of the bugs worked out prior.....ha ha I've had 4 years to build this in my head while in prison. I even took a HVAC class for the sole purpose of temp and vent control!! The only real true questions i have left are on Co2. What kind of regulator, how the hell do you hook up a timer to a Co2 tank/reg? How much will I need to pump into the room and at what intervals. Wilth out foreknowledge of what temps on 4 1k lamps will be how can I determine co2 usage?
I'll be growing DWC/ Deep Water Culture but that's neither here nor there to do with temps and co2 useage. I mean Co2 is just an option and I understand it can increase yeilds up to 15-20% I'll go turn the dam vlave on high for a few seconds each hour if I have to~ we still havent nailed co2 into the equation...yet...
