I had to turn to the experts to ask a simple question. Ive got a single 450 watt high pressure sodium fixture, with a reflecting metal shield above it. This is my third week in growing 2 white widow plants, and things are coming along decently. Heres my question: What kind of lighting schedule should I use? Ive started with about 14 hrs light and 10 hrs darkness. Should I do 24 hrs light and cut to 12/12 in flowering? Any advice would be appreciated. Thanks!
