Thank you. Much appreciatedI use GH nutes, and Sunshine #4 Mix(Home Depot). Very forgiving method, and simple. Get pH strips to test your nutes, and lose that meter. A 1500W led may only be 250 real watts, or so. 18 inches if that is right, or even less. I run a 1000W DE HID bulb at about 20 inches.
