Agreed.. its all in how you grow it.. if you have the space.. let them get a little taller.. Use techniques like topping, LST, FIMing, scrog etc. to spread out your canopy and even the light out across the whole plant instead of just trying to pound the top buds with as much light as you can... Mal is right.. sometimes less is more! You just want to make sure all the buds are getting even light.. and get rid of any of the smaller branches at the bottom of the plant that wont get any light.. these little buds will suck the juice from the tops and reduce your yeild overall.. Just keep reading bro.. there are TONS of ways to increase yeild.. you just need to figure out which one(s) will work best for your space.. Cheers!
