The most helpful advice I can give you is this... Buy a bag of Fox Farms Happy Frog soil. Get yourself sufficient lighting...I prefer T5's for seedlings, then at least 250 watts Metal Halide for vegetation. Make sure you leave your water sitting out over night to evaporate the chlorine. Test for chloramine to make sure you don't need to remove chloramine, which WON'T evaporate. Flower with an HPS light. Order your genetics from Attitude. If you want something you can't go wrong with, I would recommend DNA genetics or TGA. If you do all of this, you will have some marvelous pot to smoke. Regardless of the smog and air quality, which I'm sure is over exaggerated in the first place. I emphasize buying the Happy Frog! It is all organic, and I have pulled of multiple grows only feeding the plants one time with a low dose of organic fish emulsion. Get rid of the Miracle Grow, and put nature's love into your plants.
