Thanks for the info justpics, but im trying to see what just l.e.d lights will do with the plants.. most likely i will be getting 2 300 watt led panels to add to the 2 90 watt ufo led's i currently have.. from the videos ive seen online kind of disproves the argument that you get "loose" buds, from what ive seen the buds were tight and fat. anyways, she is 6 weeks old today, probably let her go another month or so at 18 on and 6 off than switch to 12 on 12 off.
