Know before you buy
Yes, the mat is versatile enough for home brewing, terrarium heating, and other projects that require consistent, low-level warmth. The digital thermostat allows you to dial in specific temperatures for these different uses.
Yes, the mat features an IP67 waterproof rating, meaning it is protected against water splashes and humidity common in indoor gardening. However, it should not be submerged in water.
The thermostat acts as a temperature controller that plugs between the mat and your power outlet. You set your desired temperature, and the probe monitors the soil or ambient heat to automatically cycle the mat on and off to maintain that specific range.
The mat is designed to maintain a range of 68-86℉, which is the optimal window for most seedlings. It also features double insulation to protect delicate roots from direct contact with excessive heat.
The mat is constructed from flexible PVC, allowing you to easily roll it up for compact storage when it is not in use during the off-season.
The set includes the 48" x 20.75" heat mat, the digital thermostat, and a humidity dome. You will still need to provide your own seed trays, growing medium, and seeds.
