Our Verdict
This heater is built for greenhouses and grow tents. It hits 1500W in 3 seconds and holds your exact temperature.
The temperature range goes from 40°F to 108°F. That upper limit gives plant growers control that standard home heaters cannot match.
One safety gap stands out. There is no tip-over protection. Keep it away from pets and children.
At $129, you pay a premium for greenhouse-specific features. Many 1500W heaters include timers and cost less.
If you grow plants in a tent or small greenhouse, this heater fits your needs well. For general home use, better options exist at this price.
What We Like
- Reaches full 1500W output in just 3 seconds.
- Temperature range spans 40°F to 108°F for precise plant growth control.
- Built-in thermostat holds your set temperature without manual adjusting.
- 8-foot power cord and built-in handle make moving it easy.
- Dual modes let you choose 25W quiet fan or full 1500W heat.
What Could Be Better
- No tip-over protection means it stays on if knocked over.
- No timer so you cannot schedule automatic on and off times.
- No remote control forces you to adjust settings at the unit.
- At $129, it costs more than many 1500W competitors with more features.
- Coverage tops out at 250 sq ft, below the 300 to 400 sq ft typical for 1500W heaters.
