Planning notes
Best use
Seed starting and cutting propagation in one standard 1020 tray.
Before you buy
Place the thermostat probe in the root-zone medium and keep the mat on a flat surface; do not count it as room-heating capacity.
Strengths noted
- The included thermostat covers a published 32–110°F control range.
- A 20-watt draw is modest and can be included in the energy estimate.
Considerations
- It heats one tray-sized root zone and is not a space heater.
- Probe placement matters for accurate media-temperature control.
