Hello and welcome mferreyra420,

You should maintain, during the photoperiod, 1,200-1,500 PPM of CO2.

1,500 is pretty much optium, but controllers usually have a turn on / turn off range....hence the 1200-1500 ppm.

Good luck and good growing.

lamp light = 1800ppm - 1300ppm
Flowering = 1700ppm - 1800ppm
down light = 2000ppm - 1320 ppm
sun light = 1700ppm - 1120 ppm

Variant!
