OK, I'm going to grow some white widow. So, i just wanted to know the fastest time table till i can harvest some bud.
So i'm wondering...
time for veging
time for flowering
the others are correct. you can start out using 12/12 but your yield will greatly suffer but if you do start out with 12/12 you could possibly harvest 8-10 weeks after than and then a few more weeks for drying and curing.
gardening is something you really can't rush and expect decent results.
