Oh hell one last post for the 150 people here looking for my shopping list: PH Down(Less then $10), Lydia's growth hormone ($14), One full slab of rockwool (About $6), A bottle of dutch master's veg and dutch masters flower ($10 ea. formulated in Holland I believe) A humidity dome (For about $10 bucks or less your better off getting a bonus to yield with a real dome that light passes through perfectly than a clear-ish tote or storage bin substitute!) Aquarium heater, heated floor, and or heating pad(s) (Various prices, aquarium heaters can run 5-15 for a 15 gal capacity, maybe try walmart then a pet store if you can't locate), Two aquasomething water pumps form Wal-Mart ($5.40 ea. single or double tube is acceptable. I'd buy two per tank because it's affordable and then you have a backup if one dies) Cal-Mag (If you got dutch masters you're good on nutes, if you got NPK in individualized fertilizer salts at Home Depot or a hardware store/gardening center then you may want the Cal-Mag and possibly Epson Salts, both available at any drugstore and many grocery stores. Cal-mag is a mineral supplement by the pharmacy usually, Epson salt is there too often in a white and blue milk carton container. I'd go with a teaspoon per 15gal every flush) Various full spectrum lights from hardware stores or some Plant & Aquarium fluorescent tubes (under $10 each), a Lights of America (no lights included) to hold your new grow lights! (Also $10 each, great value two lights per bal) A couple storage totes to hold the whole thing ($4-15 each if you buy cheap double or even triple up. I have two 15 gal and I *wish* I tripled-up before they lost their shape in 1 hour after finishing construction), and of course air tubing 25ft x 0.25 inch for your pumps ($5 or less), Plus air stones I got a pack of two small air stones ($2 for two) and a 10 inch bubble bar ($3) All my supplies except non-fluorescent lights and specialized hydro grow equipment is available at wal-mart dirt cheap. The tote I bought even had tubing holes MADE for air tubing I believe.Enjoy!
