Another important thing to consider is when you harvest your plants. You want the trichome heads to be mostly milky/amber for that narcotic effect. Buy yourself a 10x loup or a cheap USB microscope to see how far along your plants are. The more mber trichs the sleepier the high. You just dont want it to be 100% amber though.
