Nice work, those buds look nice and compact even on the lower branches. Right now I am currently growing c99 from female seeds under a Flowerforcer 900 diode led array. I like led's a lot, hardly no hassle. It has been vegging for about 5 months, to which I LST'd back in january and has still managed to stay nice and compact.
There is another forum on the net for their previous generation leds that turned out fantastic but I must say that the creator hasn't kept up as good SnStealth. They got .34 grams per watt, which is not good but he did not train or correctly place the lights. The link Cannabis and Marijuana seeds :: HomeGrown420 - 140w LED Grow (660/630/470/420) . Thanks for convincing me to get a couple to flower my lovely lady with. by the way I don't recommend flowerforcer they work great for vegging but not for 470 USD. PEACE
