tin, when we started growing (a lickle while ago) we were bent on vegging out for a year on a few plants. We had a ton of clones and we were moving in one plant each week and removing one plant each week....the longer the plants took to veg = the more buds you got....however, there seemed to be window of opprotunity which closes (for us at about 2 months) and what we yield does not equal the time invested in such a long veg time. Now this is just what we can come up with on our end. I believe that SG will agree with me on this...I bet 8 weeks would be plenty of veg time for ya. Incidentally, we have one more plant that is going to be flipped on 4-20, and she is the last of the original cuts taken some time ago. She is in a 15gal. rubbermaid tote and has been LST'd like crazy. She's huge and moving her out of veg and into bloom is going to be a pain in the hind parts. If she is anything like her sister that was flipped two months before, she should yield about a pound, and that's great!!!, but to me it's not worth the time we have spent on her. Hope this helps out a bit.
Keep it green tinman.
