Added c02 now have heat problem

Just added my new co2 tank to the grow room.

Before i added it, i ran my exhaust 24/7 and it kept the room between74- 76. Now that i have the co2 tank, i turn off the exhaust to inject, and the room gets up to 94deg in 25 minutes. Im running 4 600watt hps and a dehumidifier, although i havent cooled the hoods yet, i am assuming that would help.

Is an air conditioner my only friend or what?

you could diy cool tubes for your room. much cheaper then a ac unit. It might cost as much as a ac unit to set up but would pay it's self back in a few months.

The plants can tolorate the temps a little better with c02, like up into the low 90s. But I would'nt keep them there for to long. Definitly get the air cooled reflectors going. That way you can keep that air moving threw the reflector wile you spray. Getting the source of the heat out of the room is the best thing you can do anyway.

Thanks for tips guys...i just read on weedfarmer.com that people have complained that supplementing c02 during flowering will decrease potency, and that it should be turned off when you switch to 12/12?

This is a water chiller, it removes heat from the room with low power consumption

Cool those lights! Pull air from outside the room, over the lights, out of the room. Seal all connections with metal duct tape. you temps will be fine. Pump the Co2 in. Remember, when scrubbing the air in the room, exhaust in the room.

yeah man with air cooled hoods i bet your heat issues will be ok, i would try that first but then again with an ac you could ditch the dehumidifier so it might be close as far as power is concerned

thanks again friends..


I was thinking of using these to cool my lights http://www.horticulturesource.com/du...56d4a23ed8eb79

will they be enough? one fan for 2 lights in a line pushing air from another room venting into the attic?

I'm sure that booster fan would help, but I don't think it would be that efficiant with your setup. Thats what it is , just a booster. Look at an inline fan with some decent CFM, then put a speed controler on it to control your airflow.

you might get away with two fans per light one pushing one pulling. the more air you push the clooler your room will be.

Two fans per light sounds a little overkill. What I did was pulled air from a cool room, threw the reflectors, and out threw the atic. the inline fan is mounted in the atic and is pretty much silent in the room. I also have a second inline fan in the atic pulling cool air into the room threw a pasive intake at the bottom of the room. Both fans are on speed controlers, giving me really good control over my enviroment.

might be a little over kill. I missed the 8". I use the 4" and have a bigass 400w hps

Thanks guys for the help...i agree a bigger fan would be money well spent , especially with the summer coming..

i made a couple rough drafts of the fan configuration...tell me which one would work best?

do they make 6inch splitters?

I would go with #2 that way if you find one fan per line is not enough it would be ez to add if neened.

I would agree # 2. Your not pulling as far, and you don't have as many bends in the ducting. and yes you can get a 6" y splitter at home depot

what is the hd Y made out of? I've looked many times and not found what I want. Are you looking at two sets of 600w's? and pulling 440 cfm? I Still think heat is going to be an issue. Hope I'm wrong.. keep us posted

Thats not correct. The plant needs as much CO2 u can benefit it with at the proper times. For the first 2 weeks of flowering don't supplement any CO2 becuase it will stretch the plants out a bit too much. At weeks 3-6 give them lots of C02 and they will grow faster and more robust buds. The last two weeks of flowering cut all CO2 out because at this point the plant lifecycle is coming to an end and the less c02 it will focus on maturing more fully and more resinous. u should cut all nutrients aswell when you cut the CO2

if u air cool the hoods that will fix all problems, or an ac, u choose

Hello, I am just curious, are these not a good product? these water chillers? I suppose in states where water is metered, they will not work, but aside from water issues, has anyone got an opinion on them?

When they were first marketed to this type of use 10 years ago, I used a 4 fan on a 6k room that was having alot of heat issues, that room was doing 7-8 units per cycle, after we installed that chiller, it could have made the room even below the desired temperature if it was needed. the yield improved to 9-10 per cycle because of the temps.

all it cost to run was water and the electricity for the 4 fans, no compressor like a huge ass AC unit, an AC unit is like running another 1k light or 2, Id rather have that power running to light to increase yield instead of only resolving a heat issue.

added: and with this chiller, one can seal up the room and run CO2 without any heat or moisture issues as the water vapour from the burner with condense on the fins of the chiller and drain down a tube to the outside of the room or a closed bucket.

if you run cool tubes, then you would only need a 1 or 2 fan chiller.

Many benefits to using one..

Chillers are the sh%t. The only problem is, they are expensive. They are not the solution that is most recommended, but they should be. I am a big fan of chillers. The run off can be recycled. I run across them from time to time on ebay and every once in a while on Craigs.
