Sealed Tent Questions. +Rep

I have a 2x4x5 grow tent coming and I wanna run co2 in it. I will be using a 6 tube t5ho light and I was wondering if I could run co2 with a timed exhaust without running into big heat issues.

Are you useing those CFL for flowering if so I don't recommd you using co2. Those T5 give off little heat you'll have no problems with heat issues. But as far as using co2 use it with HID to take advange of the co2.

I've a friend use co2 in 1 group and not in another. Both groups, clones off mother plants and same nutes. He said while there was a difference between the two set ups, it just didn't seem worth it to him. The basics are the best bet. I've not seen the results, personally.

I use CO2 in my 2X4X6 tent only when the temps get above 85. Dont know if it helps them grow better but they definitely perk up and it minimizes leaf curling.

....check it out, use a co2 tank w/regulator and co2 monitor, this pic also includes a double hose a/c if heat is an issue.
