AC Infinity Suncore Seedling Heat Mat with Digital Thermostat – H3 & H5

AC Infinity Suncore Heat Mats – Warm Feet, Faster Roots

Seeds don't read the packet date; they read the soil temperature. A chilli seed in a cold windowsill tray can sit for three weeks doing nothing, then come up patchy. The same seed on gentle bottom heat often appears in days. The cheapest way to speed up propagation is warmth underneath.

Suncore mats use far-infrared heating film that warms quickly and spreads heat evenly, with a digital controller showing the real mat temperature, which you set to an exact number. No guessing and no scorching. The IP67 quad-layer PVC is waterproof, tough and wipes clean.

Perfect for chillies, peppers, tomatoes, cactus and succulent seed, tropical houseplant cuttings and reluctant aroid nodes.

🌿 Rose's Pro-Tip: most seeds germinate happily around 24–27°C. Once they are up, turn the mat down or off, or the seedlings will stretch.

Pairs well with: humidity domes, Cloudcom hygrometers.
