Photosynthesis and pearling times?
Ok so i just set up my 16 gal planted 3 weeks ago i started it out on excel and very little regular ferts. Then i decided to use co2 and after the second day i noticed and incredible amount of pearling, just 6 hours after the lights have been on it's just bubbles all over the place. (i'm happy) Now this is my question: Is their a way to regulate how much photoperiod my plants need buy the amount of pearling i get? If after 6 hours my planted are producing that much air do they really need to be on any longer?
This is not exacly an important question just something i been thinking about. Also does anyone know of any good articles their may be about this.
