Low Stress Training, High Stress Training, and FIM/Topping have to be my favorite tools in the cannabis cultivation arsenal. Deep Water Cultivation has to be my favorite hydroponic method. Bonzai, since I like growing in short places, for soil/organics. I do it all under a 150 watt HPS [ sometimes I toss some 42 watt CFLs in during the last couple weeks of flowering, maybe some 25 watt daylight spectrum CFLs during vegetative to balance the spectrum out ]. Gets me a couple ounces, give or take, out of each plant.
