Reliable Warmth for Germination

The VIVOSUN Seedling Heat Mat provides consistent bottom heat to help create favorable conditions for seed germination and cutting propagation. Under typical conditions, it maintains temperatures around 68–86°F (20–30°C) and can provide supplemental warmth above the surrounding ambient temperature.

Even Far-Infrared Heating

The mat uses far-infrared heating technology to distribute warmth evenly across the growing surface. Its reinforced heating film and double insulation help provide stable heating while reducing the risk of concentrated hot spots.

When used with a humidity dome, the added warmth can also help create a favorable warm and humid environment for seed starting and propagation.

Durable & Waterproof

Built with flexible, durable PVC construction, the heat mat features an IP67 waterproof surface that makes it easy to clean. The flexible design can be rolled up when not in use, making storage and transportation convenient.

For indoor use only. Do not submerge the heat mat in water.

Energy-Efficient & Versatile

The 40W heating mat measures approximately 20" x 20.75", providing enough surface area for up to two standard 1020 trays. Beyond seed starting and propagation, it can also be used for applications such as indoor gardening, terrarium warming, and home brewing.

Recommended Setup

For greater temperature control, use the heat mat with a compatible thermostat. Pairing the mat with a humidity dome can also help create a warm, humid environment for seed germination and propagation.
