People have advised me against it but unless I get a third tent going which I think is way overkill for me a my personal medicinal use, it just makes more sense to veg in one spot and flower in the other. I can keep moms and clones in the veg and autos in either.............
I just hope its a girl the stem is thickening up nice and the manifolding looking good. I think she would grow able to support the amount of mains she was topped for .Looks to me like there is plenty of elbow room in there. If you are setting up your second tent soon you should be golden. That sativa is going to be a monster bush.

15" shouldn't be a problem, even closer is possible. You can tell by doing a hand test. Hold your hand below an emitter and move it up until the reflection is so bright it turns yellow/white rather than showing the color of the hand. That's too close.
Looking amazing!!!
