Wow, I can't believe how many people just posted to talk shit on how much you paid for seeds. Your plants look good - I wouldn't have spent 100 a seed for them, but you will recoup the cost. The nice thing about growin is you get to do what you want. If you want to spend that much on seeds, go right ahead. I just hoped you saved a few for mothers... so from now on that strain is free!
What wattage do you have running? It looks like you've got (2) 1k watters going there. I've got the same set up but SOG and the yield looks like it will be less... Then again, they are clones and not expensive seeds... But OG Kush sells itself. I've found it harder to sell off-name varieties.... People hear the big names like Granddaddy, OG, White Widow, Super Skunk, etc., and it's sold.
Best of luck to you man. I hope everyone else in this forum chills out and smokes a bowl... +rep
