[tokeycones]

Hey guys, just wondering if anyone would have a ROUGH idea of potential yield if all goes well, This is my first time growing pot. Im growing 6x grandaddy purples in 30L coco pots with synthetic nuets ph to 5.8 using 1x600watt hps 1x600watt led(160 true watts) in 2/3rds of a 4x8 tent good intake/out and circulation, I'm hoping to achieve 10-12 oz which is 2 per plant
