    How much THC in those plants? 3 lights 3 results

    Here's some real testing of 3 lights. 400 watt Spectrum King (LED), 315 watt CMH (LEC), and a 750 watt GAVITA. This guy is constantly growing plants. He seems to like Spectrum King lights because of the lower heat and terpines. He also likes the resin and efficiency of the LEC. Enjoy.

    What lights should I be using?

    Hey everyone, I am new to growing, and was wondering what are the best lights to use? Currently I am using two 100w LED 1500 lumen light bulbs on just one plant, is that enough? Not enough? I'm not sure, the plant seems to be doing fine under them but we'll see. Any advice helps, thanks!
