Co2, too...

So I am about to enlisted the aide of Co2 in my grow room. It is a vented room with a 6" wind tunnel and CF scrubbing the exhaust. Since it's not a sealed room, I know that maintaining a constant ppm of 1500 is impossible but I don't currently have the funds for a portable AC unit and unless anyone thinks it's a good idea, I don't want to put a window unit in it. (I have one lying around)

What I am wondering is, would it be beneficial to put a constant slow feed of Co2 in a halo around the girls? Obviously, only during their daytime...I figure something has to be better than nothing, right? Thanks in advance for any insight!

i mean i guess its prb better then nothin, but its prob wasting a lot. can your temps stay decently steady if your blower comes on everyother hour? you could inject when the fans off for better saturation on your plants. like an hr with co2 w/ fans off, then fans on to pull out the heat out w/ co2 off? or i gues however long your temps can remain stable. just throwing out an idea idk tho

How hot does it get without venting it?Try pulling air from another room theough the hoods and dumping it.See how hot it gets.85-90 is good for co2. Make sure and feed them though! They wil want to eat!My room gets up to 88 with two 600's on a 3x6 area.Completely sealed closet.I run a cap ppm 4 and a 20lb tank. Each tank last 4 weeks! I just scrub air with my carbon filter. When i added the co2 i have to water them every 2 days instead of every 4(advanced mix #4 soil). Crazy!

Thanks bg, that gave me a little insight as to what's plausible in my tent. Keep the suggestions rollin'!
