ProSoil Premium Plant and Cannabis Soil

Giving growers the edge in high quality yield plant production.

Pro Soil plant soil is manufactured in Portland, Oregon and is designed to be a light weight, metabolism boosting organic based media ideal for sustaining healthy starts and supporting annual crops with an integrated fertilizer program.

Pro Soil is a lightweight, metabolism-boosting organic-based medium ideal for sustaining healthy starts and supporting annual crops with an integrated fertilization program.


ESSENTIAL MIX: ProSoil is a Proprietary Mix for Greenhouse, Indoor, and Outdoor Applications MADE IN THE NORTHWEST

PROEARTH MIX: Same blend as Essential Mix but with pure OMRI listed Earthworm Castings included

PROPAGATION MIX: Higher porosity than the Essential and ProEarth Mixes, with slightly less organic premix

TREELINE MIX: PH balanced, substrate-only mix for growers that like to formulate their own amendment program.

WHEN TRANSPLANTING: Thoroughly wet soil and shed excess water. When you squeeze a handful of the soil only a minimum amount of water should come out. Once the medium has become occupied by roots, water liberally. This soil only has organic premix, no time released fertilizer therefore we always recommend implementing your preferred soluble or liquid nutrients.

NOTE: Our high quality, long fiber peat moss holds more water than other substrates and even though it is a high porosity medium there is still the possibility of over-saturation.

ProSoil gives growers the extra edge with a light weight body and high quality ingredients. Our proven blend of mycorrihzae species facilitates rapid root growth and nutrient uptake. We support this growth with our signature Organic Premix, developed over many years by our in house team. All ProSoil blends are mixed on sanitized, top-grade agricultural specific machinery.
