Know before you buy
Standard heat mats typically raise soil temperature by 10–20° F above ambient levels. The Agritape High Temperature mat is engineered to reach much higher soil temperatures, specifically hitting the 90° F mark required for difficult-to-germinate crops like triploid melons.
Yes, this mat is designed to be used with an external thermostat. Because it is capable of reaching high temperatures, a thermostat is essential to monitor the soil and prevent the mat from overheating your seeds.
Absolutely. This mat is specifically designed for environments where ambient air temperatures drop below 55° F, making it an excellent choice for starting heat-loving crops like peppers and tomatoes in cooler spaces.
The mat measures 11 inches wide by 4 feet long, which is perfectly sized to accommodate two standard seed flats side-by-side.
For the best results and to ensure the soil doesn't dry out too quickly, we recommend using 128-cell plug trays or larger containers. These sizes provide enough soil volume to maintain consistent moisture while the mat provides the necessary heat.
