Pairs well with

Seeds and cuttings stall when the root zone runs cold. Cold trays slow germination, weaken root development, and drop your strike rate. The VIVOSUN Seedling Heat Mat holds a stable root-zone temperature with a thermostat built directly into the mat — a dual digital display shows real-time temperature and lets you set exactly what your seeds or clones need, no separate controller box to plug in.

Built-In Thermostat The dual digital display controller is built inline into the mat itself — set your target temp and read the real-time reading on one unit.

Even Far-Infrared Heat Far-infrared heating film spreads consistent warmth across the whole mat, with double insulation so roots never scorch.

IP67 Waterproof Surface Safe to scrub clean after a messy propagation run — built for humid domes and wet trays.

Overheat Protection Automatically powers off if the temperature climbs too high. Made from durable PVC and PET film to MET standards.

Flexible & Easy to Store Stretchable, foldable mat rolls away between seasons without taking up bench space.

Grow Guys Tip

Root-zone warmth is one of the fastest ways to lift germination rates — most seeds strike best between 20–30°C.
Run the mat under a humidity dome and you get warmth plus moisture retention — seeds and cuttings root faster and more consistently.
Once seedlings are up, back the temperature off slightly to prevent stretch and push stronger root growth.

How to Set It Up

1

Flatten the mat on a level, insulated surface — a bench or shelf, not carpet or bedding.

2

Place your propagation tray directly on top of the mat.

3

Plug in and set your target temperature with the 3-button controller — the display shows both your set point and the live mat temperature.

4

Cover with a humidity dome to hold warmth and moisture around your seeds or cuttings.

5

Once seedlings emerge, lower the set temperature slightly and vent the dome to harden them off.

Pairs Well With

Propagation Gear

Trays, domes and cloning gear to sit on top of the mat.

Environment Control

Monitors and controllers to keep air temp and humidity in check around your propagation area.

Grow Lighting

Gentle propagation lighting to pair with root-zone warmth for strong early growth.

Frequently Asked Questions

Is the thermostat built in?

Yes. The dual digital display thermostat is built inline into the mat — it is not a separate controller box. Product photos may show it differently, but the unit you receive has the controller integrated.

What is a seedling heat mat used for?

A seedling heat mat warms the root zone under propagation trays, helping seeds germinate faster and cuttings root more reliably.

What temperature should I set it to?

Most seeds germinate best between 20–30°C. The thermostat holds your set point automatically and can be adjusted up to a maximum of 50°C (122°F) depending on plant type and room conditions.

Can it be used for cloning cuttings?

Yes. Stable root-zone warmth works for both seed germination and rooting cuttings — pair it with a humidity dome for the best strike rate.

Is the heat mat waterproof?

Yes. The surface is IP67 rated, so it handles humid propagation environments and is safe to scrub clean between runs.

Faster Germination Starts at the Roots
