Instructions for use included.

An important first step in controlling weeds, pests (excellent for common fugus gnats), and pathogens safely, economically, and chemical-free in your screened soil or screened finished compost before using for propagating seeds and plants.  The sterilizer is filled to the top of the container and then the unit is plugged in. The thermostat is then set to the correct pasteurizing temperature. The indicator light will glow until the batch is done and the sterilizer automatically shuts off.  After the light goes off, wait 15 minutes then pick up the unit and the pasteurized soil will drop out the bottom. Next, beneficial amendments and supplements may be added for customized growing mixes. Important design notes: Pro-Grow sterilizer’s proven design and specially selected materials allow for easy cleaning and drying to prevent molds and to promote longevity of equipment. Also, the special design is important because the dirt/growing media is NOT shoveled out of the sterilizer…when a metal shovel hits a metal unit, there would be denting and damage. Pro-Grow engineering has spent decades designing all of their equipment in their labs and is committed to manufacturing equipment with special designs features that are built-to-last.

Along with using an excellent quality pasteurized growing mix, sterilizing your containers and tools is another important step. Seed flats, pots, trays, and tools should be thoroughly washed and disinfected. Rinse and allow to dry before using again.
