Growstones ideal alternative to perlite, parboiled rice hulls
Date:12/14/2011

de is produced as the glass particles are heated and fused together, trapping air spaces inside the glass. The result is an expanded, lightweight product that is cooled before being ground to the desired size.

Evans' experiments showed that Growstones had an AFP higher than that of both peat and perlite. Additionally, when added to peat at a concentration of at least 15%, Growstones increased the AFP of the resulting peat-based substrate.

"Growstones can be used in a similar manner to perlite and PBH as an aggregate to increase AFP of peat based substrates", Evans said. "The primary differences were that, at concentrations of 25% or more, GS resulted in a higher AFP than equivalent perlite-containing substrates. Also, substrates containing 20% or more GS had a higher water-holding capacity than equivalent perlite- and PBH-containing substrates, and GS-containing substrates had a higher bulk density than equivalent perlite- and PBH-containing substrates."

All GS-containing substrates had physical properties within recommended ranges. Vinca, impatiens, and geranium plugs grown in GS-containing substrates were comparable to plants grown in equivalent perlite- and PBH-containing substrates.

Evans said that the experiments showed that Growstones can be successfully used as a component for substrates used in greenhouse crop production.
