This grows looking great man. Glad to see another LED grow doing good. A future word of advice, if you're growing sativa dominant strains and you're limited height wise, scrogging is a very good thing to look into. Sativas have crazy stretch during flower. Most will triple in size and some will quadruple. So if you're vegging to 15 inches and it quadruples in size during flower, because there's another stretch during week 5-6, you're getting a 60 inch plant. That's 5 feet man! I'm sure you'll get some great buds from this, I'm just tryin to throw you a heads up.
