Hi mike
Sometimes questions get over looked, it wasn't done intentionally. There are alot of great people here who do help out, sometimes not as quick as we'd like, but hey , that's life. Calling us a pathetic community isn't the answer.
to answer your questions
12/12 light cycle for WW takes a good 8 weeks if not more. the plants will show when it time to harvest just like growalot said.
I've never cut the lights down below 12 hours, but it's worth a try. let us know how it worked out.
the 150 watt light might not be enough for big buds, floro's are fairly cheep you might want to add one of them.
peace
heart
