if you're using cfls most people will tell ya to put them into flower at like 12" and in flowering depending on the lights it can get 2-3x the size before u put it into flowering but I'd go 18/6 first and let them grow some probably but that's just my :twocents:
nick19882003 Reviewed by nick19882003 on . Second attempt-First grow log So I'm just now getting serious about growing. Here's my two plants, their both 3wks old. Mistake #1. Used 10k aquarium MH 250watt for week1. Mistake #2. feeding them only micro nutrients for two 1/2weeks. Mistake #3. 24/7 light Forgot to mention that the temps went over 100deg for a prolonged period of time while i was running the 250wat MH with no ventilation. I believe thats what stunted the smaller plant so badly. Rating: 5
