i am a extremely novice growe myself .. on my first real grow starting with 4 plants. ive gotten pretty lost in the last few days even after researching for hours on end.. if anyone is unclear about anything for their entire grow go to youtube.com and watch the 7 "Learning to Grow" videos.. itll take just over an hour but after watching them all i feel that my crop is going to be very succesful... on another side note they also have sweet videos of a growing marijuana plant over several months in just a minute. its awesome to watch
