So I got new lights recently and they are great. I read that my plants can't use all that light (above about 900 lux. My plants are usually bathed in about 2000 lux. If they can't use the light, I don't want to waste it. Either I should add CO2 and get the benefits or grow at a lower level (turn down the drivers), if the light is wasted. I could use peoples' perspective who have run CO2. Can anyone give advice?
