Soil Steaming
Using a commercial soil steamer is a highly effective way to prepare soil in your greenhouses, high tunnels, or open fields for planting. It uses steam to rid the substrate of fungi, diseases, invasive species, weed seeds, and other harmful biological materials. Using steam before planting gives you larger, healthier plants with improved yields.
How the Sioux Commecial Soil Steamer Works?
Sioux's various sized commercial steam generator models produces 370-3,450 lbs. of steam per hour. A steam sock and tarp allow you to deliver steam evenly to the area. Smaller Sioux steam generators heats a single 20' x 100' section of soil up to 180° Fahrenheit (82° C). Multiple sections can be heated simultaneously with larger models.
We recommend that you allow the soil to remain at 170°-180° Fahrenheit (76°-82°C) for a minimum of 30 minutes. Sustaining this temperature range for at least half an hour removes:
- Weed seeds
- Harmful pathogens
- Nematodes
- Other contaminants

The total steaming time can change according to soil type and ambient temperatures. When the steaming process is complete and the soil is cool again, you are ready to plant.

Sustainable
You are practicing environmental stewardship by using steam to clean your soil and growing media. A commercial soil steamer uses clean water to kill pathogens, eliminating the need for hazardous or now-banned chemicals. Using soil steaming equipment produces clean, organic, and reusable growing media.
