I purchased an AeroGarden Pro 100 at a yard sale last week. First, does anyone have any experience with this method of growing. Secondly, I would like to know what premixed fertilizer I should use that I can buy at Lowes. Five of the seven seeds germinated, are a week old and about 3 inches tall. First time grower here guys and gals. I was told that these seeds were a Northern Lights seeds. Thanks!
