I've actually read in one of Jorge Cervantes' books, that people argue over the 24/0 and 18/6 light schedules claiming one is better than the other.. Instead of either of those, he said that the best growth & female rate is 16/8, which Jorge claims are better than the both. But im sure as you guys know, most growers like to do it their way and have their own opinions about it... my thing is, Why would the plants want the sun all day long? I mean, do outdoor plants differ from indoor plant growth and light cycle? The sun isnt out all day! I think its more natural to have the plant sitting in at least 6 hours of darkness rather than giving it sun all day and night long.
