First time grower here...getting tired of crappy product from the street vendors so I saved a bunch of seeds from the best stuff we had purchased and decided to grow our own. Started about two weeks ago with a Burpee growing tray and dome from Home Depot. We planted two seeds in each peat cube as we had read on-line. Almost all of them sprouted, and now I have to decide which seedlings to clip and which to keep. When they are only 3 inches high it is a genuine guessing game with regard to the sex, right? We have a 36 inch by 20 inch closet that we are attempting to convert into a growing room. I just built a shelf approximately 16 inches off the floor, and order both a 400 Watt HPS and 400 Watt MH ballast system on Ebay. Everything I read on-line gives me a somehat different answer. Can anyone help? I have been taking tons of pictures to document out progress. Please help two new closte-growers. Which lights do I use and when? How close should they be to the leaves of the plant? Miracle Grow fertilizer or not? Aaaarrrggghhh!! Help...Please!
