Personally, ive tried almost about evrything from Home Depot and Lows, Walmart.....you name it with little success......As soon as I switched to professional Hydro Nutes....I started having success grows......Lots of people do it the HD or Lows way...ive just not had much success that way! There is no Hydro Store in your area? or within hours away? You should buy a pre paid CC and try to order.....it will make the job just that much easier!
