OK I just finished my first grow and i grew some smaller plants because of bad timing and space issues i got about 2oz. off of 18" plants.now ive got a huge building to grow in and i have set it up with 500w worth of CFL's plus a 48" dual flourescent ballast with 2 40w "grow" flourescents and im vegging. these lights are about 9 inches away from the plants and my new sprouts are doing good. at a week they are about 2 inches tall and have nice colors and leaves. 8 plants total.im not in a position to buy MH or HPS light systems so CFL is it for now.I think im going to be ok i got 8 sprouts and i figure about 3 or 4 will be male so when i get to flowering i wont have as many so the lighting should be sufficient i think.now here is my question i need to understand nutrients these are soil grow so when do i start fert and what should be my schedule.thanks for any help
