When you turn on your co2 your supposed to turn off all fans and blowers. my question is how long can my blower be off before my 600 hps gets too hot. im just worried of burning the tops of my plants. i can only raise my light another 1 inch

lights and blowers are fine as long as the OC2 is pointed at your plants, co2 falls, is heavier than air. just dont have an exhaust on or you are throwing your $$ out the window.

You have to find out for yourself..every rooms different..

In order for supplemental Co2 to work, you need 85-95 degree temps for it to be beneficial.

A sealed room is pretty much the only way to go.. Thats what im doing.

As far as room temps are concerned, it will not make the top of your plant burn up, only your light can.

Run an oscillating fan in your growspace.. that'll cool the top of your plant if you direct the air to that level.

thanks for the feed back guys! but im not worried about c02 burning the plants im worried about the light. i had some minor buring from having the light to close to my tops a few weeks ago. guess they grew a little too fast:). The blower that cools my light is also my exhaust. so by turning off my exhaust my light will start warming. anyone been in my shoes? I just dont want the room to get too hot while im giving em C02. im planing on using dry ice in the last 4 weeks of flowering. What i was thinking was to put some CFLS in the room and while i introduce CO2 i would turn off the HPS and blower and turn on the cfls so my ladies can soak in C02 for a hour or two a couple/three times a week. ANY THOUGHTS?

HMMMMmmmmmm. While it's true that you don't want the CO2 being pulled out of the room via an exhaust fan, you still want a fan on to dispurse the CO2 evenly throughout the room so as to not have a build up of CO2 in any one area, or let the CO2 settle to the floor and somewhat waste it. These fans should also help to prevent any burn on the foliage as well.

you need to use both sides of your hood. run 1 tube from the outside of your house into 1 side of you hood and the other hole in your hood should be connected to a inline fan and be blown outside. it is a closed air line. it will do wonders for you heat problem. and it wont affect your co2 levels.
