co2 generator?

[Zandor]

zandor dont plants benifit more from co2 at night ?thats what i always thought i heard,
if so im wondering why it would matter what lights you use with co2 if the lights are off

thanks

No the plant can only process the extra amount of CO² when the lights are on. CO² in the dark is only a waist of money, unless you are using it as a pest control but that would be expensive pest control.

It takes about 10,000 lumens for the plant to process CO² levels above 900 ppm. Normal air runs about 300 ppm and for a good growth supplement the level is above 1500 ppm. I run mine at 1800 ppm just so you can compair.
