Don't some of you tire so over this scientific mumbo-jumbo? In retrospect we are growing nothing more than a weed, and we are probably providing much more so than nature on its behalf. Miracle Gro is loaded with nutrients and will produce bountiful buds. The mistakes we mortals make is in insufficient light, lack of humidity, and of course unnecessary pampering with additional nutrients and over watering. This paranoia over nutrients and watering is what kills your plants. Just let them grow and you will see substantial results.
