a lot depends on ur light level
if u have bookoos of light, ur plants need it as soon as ur nuclear blast of light comes on

on slower growing tanks, the fat reserver of carbon is used during the morning to supplement co2 dosage until proper levels can be achieved

i turn my co2 on about 30 minutes before lights, which is realyl all u should need. 45 minutes at most.. co2 concentrations change in about 15 minutes
