this is my first indoor grow and i think im doing all right let me know if not!! i started some seeds on earth day from atittude. some went out and 3 i keep to try indoor i ran them in and outside for a month or so i have a 400w mh/hps and just started 12/12 cuz i thought about how they double or tripple should i get a bigger light. I ducted a ac to the bottom so heat is not a prob should i get more light for these girls and when i up grade what should i do
400 watts should be adequate for 4 plants but if you are itching for more light and money aint a problem you should either get another 400w or 1000w to get a max yield
