Inkbird Plus - Heat Pad Seedling Mat - 58 x 25 cms

Don't let winter stop you. Keep propagating, growing and repotting all year-round. Warmth speeds up root growth and grows stronger roots while keeping cold-tolerant tropicals warm over winter. Combine your new Inkbird PLUS heat mat with a grow light for even better results. Put your heat mat under a prop tank, grow house or cabinet, or just pop seedling trays or pots directly on top (yes, Inkbird PLUS heat mats are waterproof too). Very affordable to run. Based on 8 hours a day, 7 days a week, the cost is around $4.50 total running for 3 months right through winter


Why get an Inkbird PLUS heat mat?

- The new PLUS model has an upgraded heating film that reaches temperature faster, and maintains a more stable, gentle heat that's more evenly distributed throughout the mat surface.

- Waterproof: Rated IP67. Waterproof against spills and misting. Simply wipe dry.

- Increases success rate for cuttings and germination. Seeds and cuttings germinate and root faster and roots produced are stronger.

- Super thin and flexible. Can be rolled up or stored flat.

- 20 watts for lower power consumption.

- 5'9" cord. Almost 6 foot in length. Comes with plug. Connect to a power outlet, power board or heat mat controller (available separately).

- Compatible with the Inkbird ITC-306T heat mat controller which monitors ambient temperature, turns your pad on and off to maintain your chosen temperature/s, and allows you to set separate day vs night temperatures (controller available here).

- The new PLUS model also has improved cord insulation for use indoors and out, including in higher humidity environments such as greenhouses.

What can heat pads be used for?

Keep propagating and growing all year-round. Warmth speeds up root growth and recovery after repotting. But heat mats are not just for the babies. Also a great way to keep tropical-loving indoor plants warm over winter and to look after your high-maintenance jungle members. I use mine under my Ikea cabinet (last winter I had a heat mat on 24/7 under my prop tank terrarium). A warmer root temperature also helps stressed or struggling plants recover.

Heat mats also help over-watered plants dry out faster, reducing the risk of root rot in winter. Great for an emergency fix for accidental over-watering all year-round. Heat mats also mean you can repot all year-round. Maintaining a root temperature of over 20 degrees helps roots recover and start growing again following repotting or after removing damaged roots after root rot.

You can also grow seeds and seedlings all year-round indoors. Most seeds won't germinate unless temperatures are between 20 to 30 degrees (the same temperature range of an Inkbird PLUS heat mat). With a heat mat and decent light you can grow herbs like oregano, parsley, sage, thyme, chives and more indoors, even in winter.

These heat mats are designed to work by themselves, but for more control over daytime vs nightime temperatures, get the Inkbird ITC-306T heat mat temperature controller

What temperature does it heat to?

Inkbird heat to 20 to 30 degrees (root temperature) depending on ambient room temperature, airflow, and the surface you put it on. When used without a controller, they average 10 degrees above the ambient temperature. With the right conditions it can get hotter than this (up to 40 degrees) but you'll need to manipulate the environment to maintain higher temperatures, such as adding an insulation pad under your heat mat. See tips for set-up and use below.

To control minimum and maximum, and set a different temperature for daytime vs night-time, you can also get a compatible heat mat controller. The Inkbird PLUS heat mat works best with the Inkbird ITC-206T controller (available separately here).

However these are also made to work without a controller. and average 10 degrees warmer than the room temperature. Many people leave them on 24/7 over winter, to avoid cold shock from overnight drops in temperature, or you can also pop this on overnight-only.

What size is it?

The Inkbird PLUS heat mat measures a smidge under 58cms long by 25.5cms wide and about 2mms thick. The standard size for a seedling heat mat, but thinner than most.
