any thoughts on using water from vacuuming my fish tanks as the fertilizer for a hydro grow that I experimented with back in the late 70s. the plant grew to be about 5' but very sparce, yet potent. I used fish tank flourecent grow lights. the medium was fish tank gravel and vermiculite. a hydro grow before its time is how I like to think of it.
