This was near a year ago, no updates, whats your setup?
How are you getting enough light thru the vegetation to achieve that weight?
How are you cooling the system?
What grow material/style?
If you are rockin' the big guns, show 'em off! I am running an entire bedroom, I would fucking love to get the same yield from a 4'x4' tent.... My highest yielder so far was around 10-11oz dry, on a Jack Herer (greenhouse seeds) under a pair of 600w hps....
What kinda veg time? Scrogged?
