I would think about it what you really want out of your grow, any fool can grow 2 lbs of blue dream... but your going to be one sad mo fo if that is all your going to be smoking. If your trying to sell it you may have a problem too because any heavy yielders are being used by commercial grows and they have a lot more to throw out into the world than you. The market is flooded with bunk weed... is that what you want to add to the market?
Grow some dank bro, quality before quantity. You will smoke less dank your body will love you for it and your friends will be in awe. Hop on the Dank Train bra... no need to be growin schwag.
