Guys im a newbie to this and im not sure if this has been brought up before? My plants werent doing so well, I think it was over feeding. But anyway I was cleaning out my aquarium and thought that maybe the water from the tank might help them out. The Ph was exactly 5.5 perfect! The tank has piranah and a huge sucker fish in it so they are very messy. Im using a bubbleponics system that I made myself. I filled my spraybottles and went to my groom I shut the pumps off and sat in there squirted the hydroton myself while I smoked.( I smoked in there before this too) Im telling ya what ever is in that water is the secrect to growing! I just wish my aquarium was the size of the ones at Seaworld! lol It has been about 4 days now of me doing this every day for about an hour and the plants have went from lifeless and hopeless to totally rebounding and showing new growth. I wish I would have taken a before and after pic!
