Clean way to add extra Co2?

[included]

However, I have found that just 150 Watts of the proper wavelength light, and >80F. temperatures make excellent use of the extra CO2.:thumbsup:

I'm certainly about to test that theory with my next grow. I'll be using two tri-band LED UFOs, and four 4' T5 sun blaze strips (two grow spec, two bloom spec) in a small cabinet with my C02 system. Temp should hold steady at about 85-90F.

Lumens per square foot will be at about 3650... so lower than the typical "requirement"... but it's mostly concentrated at the most useful spectrums.

I tried baking soda and vinegar in the past and it made a merry mess. :( Still, when growing with LED's you need : more heat more Co2 less water less nutes My current cabinet is much smaller- 2' X 1' X 4' 8". and has an active air intake (camouflaged by a kitty litter box) so...what's a clean, safe way to increase Co2 levels? Does it really matter for such a small grow (2 plants in a small cabinet)? Rating: 5
