How to Use It – 5 Easy Steps

1. Place the heat mat on a flat, dry surface
2. Position your seed tray or propagation dome on top
3. Insert the temperature probe into the soil or rooting medium
4. Set the controller: 21–29°C for seeds, 24–27°C for cuttings
5. Pair with a humidity dome to lock in moisture and maximise success

Pro Tips

• Always run the heat mat through the controller – never plug it in directly
• Warm soil dries out faster, so check moisture levels daily
• After a power cut, the controller needs to be reprogrammed
• In small grow tents, the mat can help gently lift ambient temperatures – adjust carefully to avoid overheating
