    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.
