While I admit that Flourite is attractive on it's own, I would have to
say that my method has mostly due with the different nutrient
complexes provided by the Onyx as opposed to just Flourite... it's
the "shotgun" approach to nourishing plants.... two different
nutrient-rich substrates combined with a very porous substrate to keep
a "loose" bed of gravel which promotes sufficient water circulation
into the root zone, as well as a healthier colony of beneficial
bacteria. Any thoughts?
