either get a 250watt or 400wattHPS HID for flower or use the sun to flower. if they are from seed it will take 4-6 weeks till mature enough to flower. you can before but it is recomended that you wait till there are alternating node arrangements. you have a few things to worry about. light, ventilation, food, and water, and pests. take a gander at the grow FAQ when you get the chance, if you havent already......i want to be prepared. I am trying inside with sunlight and flourescents now. when should i change lighting to 12/12?
any other tips are greatly appreciated.
