product researchers recently conducted
some side-by-side trials testing Sunleaves Silica Stone against traditional
hydroponic media including expanded clay pellets as
well as a silica mixture from an alternate source.
Plants growing in Sunleaves Silica Stone benefited
in several ways including increased overall yields
and more compact growth.
Over a three-month period, sweet
basil plants were grown in continuous aeration hydroponics
systems. In each system, a submersible pump suctioned
to the bottom of the nutrient reservoir continually
splashed one-part, Ionic nutrient
solution onto plant roots. In lieu of plastic net cups,
plants were contained in fibrous root pots made of
shredded, compressed coconut shell fiber. As for garden
lighting, one 1000-watt metal halide lamp was positioned
18 inches above each basil plant, and plants received
18 hours of blue-spectrum light daily.
In the following photos, growing
media represented clockwise from lower left are Sunleaves
Silica Stone, expanded clay pellets, Sunleaves Silica
Stone, and the alternate silica mixture.
the first quarter of the experiment, basil
plants appear to be growing at a similar
the second quarter, the basil plants growing
in Sunleaves silica stone have begun to
outperform the others with larger leaves,
thicker stems, and more compact growth.
