Once carefully graded, peat moss assures that qualities of each grade are optimized for based on grower and uses for a final product reaching high quality requirements.

This pine bark is screened, partially composted and aged to produce a coarse base ingredient for blending PRO-MIX growing media to add bulk density, drainage and air-porosity.
-
PERLITE
?
Perlite is an alumino-silicate ore of volcanic origin. The raw ore is crushed, graded and screened in various particle sizes. Perlite has a high total-porosity and improves drainage and air porosity.
-
LIMESTONE
?
Used to adjust pH to optimum range. Also a source of Calcium and Magnesium.
-
WETTING AGENT
?
A wetting agent is a substance that reduces the surface tension of water, allowing water to penetrate and uniformly wet growing media.
