How much CO2 do you use?

[een]

I am just wondering for those of you that use CO2, can you tell me how much you use per month or year, what controller you use and what area you grow in?

I use a green air cd-6 in an 8 by 8 flower room with 3 1k vertizontals,I keep it at 1000-1200PPM and I use a tank every couple weeks(propane),so it comes out roughly to a dollar a day

Thats a lot of heat for an 8x8 room. What type of cooling system are you using. I have a 10x10 ft. room with 2 vertizontal 1000's using a 12" elicent for exhaust and still have to watch the heat...thanks.

I have a 12000 btu unit in the window(just replaced last week) and a 9000 btu portable in an 8 by 8 room.The unit is mounted high on the wall is has little effect on temps down below when theres 3 1K vertizontals,I want around 80 degrees at the canopy anyway,it works out perfect in my room.Sometimes running the dehumid kicks it up during the hottest hours but I always run it at night when RH rises 20-30%.You mount the unit as high up on the wall as to not be a fire hazard to the ceiling,I'll go look real quick.The very top of the unit is 13 inches off the ceiling.It has little effect on the temps with all the BTU's lol.I use a green air cd-6 and a cyclestat to control frequency and duration of burn
