Hello, I am looking for advise/guidance on constructing a grow shelf. I saw some growing shelves in the Gardeners Supply catalog, but I am not able to spend $500+ on it. I have viewed some websites showing homemade grow shelves with the lights but I am really not sure what I should be buying. I found a wire shelving unit to purchase but I am not sure what kind or types of grow lights I should purchase. All of the different kinds and types available is overwhelming for a beginner. I am starting the seedlings for my organic vegetable garden if that helps. Any help is greatly appreciated!
