I'm getting kind of tired of filling and refilling my 1 gallon jug with
fertilizer solution, but I remember reading some reservations about hose-end
mixers. I fertilize 1/2 strength every other week and flush with water the
other times, which seems to work for the roughly 75 plants in my little GH.
Any suggestions?
