Really tell me more!, what is the cost? Im using sunshine mix4 with the recipe for success kit, I have two bubbleponics kits, I wish i didnt buy, thinking about selling on ebay. I have not really used them because they seem like the plants would be to crowed and once the plants were big water change outs would be a bitch, im thinking about the Flo & gro but i like the ease of soil but im tired of the dirt and having to dig holes in my yard to dispose of the plant waste,
