IMHO.... You should just leave them outside all the time. The 6000 lumens you have in the shed isn't enough to really do them any good, and the days are getting longer right now so even if they show sex between now and June 21st, they shouldn't begin full-scale flower.

What about the drooping/perking back up? Do they droop after you water them and perk back up after they dry out a little? Perky by day / droopy by night? It's normal for outdoor plants to droop at night and perk up in the daytime, like they're reaching up to grab every bit of sunshine they can get... :thumbsup:
