1) How long would a quart each of the 3part nutrients last me in a 18 gallon resovoir(dwc)?
2) And how frequently do you need to change out the water to prevent buildup?
3) I was thinking about putting some lava rocks into the tank to help filter out the bad bacteria; how effective would that be and is it worth it?
4)besides the gh flora series, i was looking to get liquid karma, megagro, and also some superthrive... sound complete enough or should i be looking at any other products? (ill think about bloom bud and big bud when the time comes, for now, they are babies)
5)can any of the previously mentioned nutrients be used for soil grows with any success?
