Question about shortened bloom time

My plants have been blooming for a couple of weeks and I heard that if my lights are on for only 8 hours per day instead of the 12 they're on now, I can get them to bud out in only 2-3 more weeks. Is that true? I'm growing California Skunk from Amsterdam and the plants are about 3 1/2 to 4 feet high now with small buds all over them.

keep them 12/12 i have'nt heard about 8 hours being better for finishing off

Whats up Little Sis? I just found put cutting them to 10 on and 14 off quickings the girlies. Said the buds wont be as dense, but the smoke is the same. Im doing Love Potion #1 and just going to seed batch them so its perfect for what Im doing. I also have Cherry Purple babies going right now and going to do the same to them also. Then going back to 12/12. Hope this helps LS.
