Ive got a 9 by 7 room, curtain door can be open, Ive got a gas heater in the hallway next to the room providing co2. pleanty of fan power to circulate air from other parts of building for now I have 2 400w hps and no temp or humidity problems (this is my flowering room) Should I still have fresh outdoor air coming strait into the room? or is what I have good? just need a couple suggestions or opinions Thanx ESKAMO
I think if you have co2 generation and your temp/humidity is good - just keep doing what you're doing! Good luck!
Don't take outside air, this will screw big time with your temperature. Plus adding air will hurt the c02 density (unless you use timers) If temp is good you should be fine, you might want to add venting to kill the smell ( you can make carbon filter quick and cheap) but long as air is moving than you are good.
Sounds like a sweet setup....if temps and humidity are good, and you have CO2 being generated, I think you should let it ride.
