Soil Sterilizers - Stainless Steel Heating Tubes Throughout

Welcome to Durable Greenhouse & Nursery Equipment and thank you for your business!


An important first step for strong, healthy seed and plant propagation is controlling soilborne weeds, pests (excellent for common fungus gnats), molds (damping off) and disease efficiently, safely, and chemical-free in soil, finished compost, potting mix, and other growing media. These Professional Grade Pro-Grow Electric Soil Sterilizers, used by successful growers and research labs around the world, are designed to have an adjustable temperature range of 140-200 degrees F. Pro-Grow's unique proven design and materials selection is important for heating throughout, finished mix falls straight down through bottom, easy cleaning, and open drying design for mold prevention and longevity of equipment.

Many plant pathogens can be found in soil, peat, and sand and when greenhouse crops are planted where these exist, disease may begin because nutrients leak from the plant roots and stimulate pathogens into activity. 

Pasteurizing with Pro-Grow's stainless steel models is an effective and efficient option for controlling the quality of your growing mixes by eliminating various soilborne pathogens, unwanted common pests (i.e. snails, fungus gnats, and eggs), and weed seeds BEFORE planting your seeds, seedlings, and cuttings into them. Pasteurization to destroy most organisms is done by applying heat until the soil reaches 180-190 degrees F for 30 minutes. After pasteurizing, selected beneficial amendments and supplements can be added for customized growing mixes.  

For larger bulky materials (i.e. long fiber materials such as unmilled Sphagnum moss), Pro-Grow's XP models are specially designed with extra wide openings and are popular with Orchid Growers. 

Pro-Grow's unique design, using stainless steel heating rods (no rods on smallest 1 cu.ft model), allows for thorough heating throughout the unit. Grower's choice around the world. Grow with what works.
