hey jefffar, i actually had it tied down during veg but ripped 2 stems off (accidently) while makin adjustments to the plants. so it acted like a topping also i assume.thank you for the comments, im sure ur grow will be a blast for u. just make sure ur plants have good ventilation and a proper feeding cycle and everything else will just flow =] i pretty much just winged my whole grow, had fun with it and just learned from what i did (or didnt do) best of luck to ya tho =]!
love you all
