Agree 100%! My exhaust remains off while my lights are on and Co2 supplementation is active. When the lights and co2 shut off, my exhaust kicks on just for long enough to empty the stale air out of the room.

3000 ppm? you sure?

^^^^Not that I've tried those levels but it goes against everything I've read. Probably got that high when my valve stuck open one day lol. Never checked levels but it emptied a full cylinder in 12 hours. Think it actually killed some fungus gnats lol.

Good thing you were just using bottled gas!
Try having a solenoid stuck open in a natural gas burning co2 generator. The fucker won't shut off. At least with LP, the bottle empties.
CAP was selling and fixing their fucked up generators with defective solenoids before they shut down and got snatched up by hydrofarm. You wouldn't believe how many times I've had that happen to me. You think everything is gonna be good after replacing the bad generator, only to walk into your bloomroom in the morning and start seeing stars/almost faint. No good! But yeah, 3000ppm lmao
My larger bloom rooms are perpetual, i set them at 1000ppm. Set it and forget it. It works fantastic

Like I said earlier, I've just dabbled and went out last year and bought a whole bunch of shit. Was gonna get the CO2 going properly and also do a HP aero setup. The stuff is still sitting there, started to think about all the shit I still needed to make it all work lol. Gets complicated when you start running a sealed room in 85/90 F summers 
. I was running it at timed intervals and checked it periodically with my combustion meter lol. My controller is a Honeywell with 3 adjustable presets that step the valve. Just need AC, sealed lights, etc etc lol

Wow u must not have a problem with heat in your room. I'd think during the whole day with the lights blaring, your temps will get u up to 100 degrees unless you're running LEDs. My attic/2nd floor is my only option to grow until I build a hoophouse, and winters are only time it stays under 85 deg. How many cycles do tanks replenish new CO2 per day? Or do they kick on, at say 600ppm, to get to full strength (1500ppm)?

I'm running HID's in a basement room. My temps run between 80-86 degrees. I run my lights at night since it's cooler, and I have an intake fan that brings in cool air from outside. It's hooked up to a thermometer that kicks on the intake fan if it gets too warm. I imagine in the summertime I'll probably need to install an ac (I've only grown in this room this fall/winter) but I haven't needed to yet. If you're in an attic or second floor space does it have a window? A window ac would be your cheapest and most efficient option and is totally worth in terms of what consistent temperature can do for your yield.
My Co2 is hooked up to a titan controller that kicks on the Co2 tank when the ppm in the room falls below 1500ppm. Although I start it at 1000ppm, move it to 1250, then settle at 1500 once the plants reach their largest veg size before I flower them. Then I keep co2 at 1500ppm for flower. A 20 pound tank lasts me 5 to 6 days when I'm running it at 1500ppm during flower cycle.
