You may want to check out some of the grower forums, if you haven't already. You could find some info there to double, triple or even quadruple your yield off of your plant, for not a lot of money, I am thinking. Just getting light closer to your plants, for example, without burning it...the proper number of lumens to use, etc. All very useful stuff for sure. Best of Luck!
what are the dimensions of your box? are you growing a strain off the net or just seeds you had? how long did you veg for before switching to 12/12? edit : I just came back to look at this and HOLY FUCK those 2 fan leaves are GINORMOUS. lmfao I was ripped before and didnt notice but holy shizzz man lol
