you will see lil if any benefit from co2 supplementation... You do not have enough environmental factors at or above optimum to use the extra co2 so the benefits are about nil.... cheaper and more productive would be to get a larger wattage light fixture, better temp/rh control and increased ventilation...accomplish these then co2 will show its usefulnessThis is my first real grow. the others were plain regular seeds that I got from my baggy on the streets so I can experiment with and learn. got tired of the bunk weed that was out their.
Part of why I am so enthralled by this hobby/obsession ...lol... It reminds me of chess....no matter how much you know nor how good you grow one can always improve....I'm with Illumination on this. Thats why I asked how long you'd been at it. Get your basics down first, THEN start worrying about the advanced stuff. It's gonna be a real eye opening experience just getting your first few girls to the finish line.
