hey man,i just run a 3x3 tent with a cooltube 600 watt with large adjusta shade,in the last run i spoke of i flowered out three mother plants in 5gal coco hempy buckets,i wasnt realy goin for max yeild as it was just a test run with the coco hempy style. this run im growin a single plant in the same setup and iv trained it to fill the space im almost through the second week of flower and it looks like 10 oz could easily come from this lady.il let you know in a month or so how it goes. also iv switched to a single part coco nute from vitalink,and add pk13-14 plus au60root repair from nulife! this plant is healthier than my previous grow by far!
