Fertilpot works well for hydroponic / aquaponic systems.  Because Fertilpot is about 85% porous, there is no need to cut in traditional drain holes.  This allows the roots to pass easily through the pot and into the nutrient solution, while retaining the growing substrate in the Fertilpot.  No more clogging of filters or build up of a substrate sludge in your tanks or gutters.
