I say veg em for 6 weeks, or 8 if you have the patience. For me, it kinda depends on how big they are growing. Most strains will double to tripple in size during flowering. I was gonna veg mine 8 weeks but they are already around 15 inches tall so Im gonna go 12/12 at 6 weeks instead. At least thats my excuse, im getting impatient.
Jarhead made some good points. Keep it simple, because it is. And this is supposed to be fun, so enjoy it. The real fun starts when you go 12/12 and get to watch buds grow for 2 months. Very exciting stuff, too bad your husband doesnt care as much as you do. My girl doesnt care either, she just want to smoke. I enjoy the whole growing process, from seed/clone to smoke. Thats why I love this site, kind people to share the experience with.
