    How to Use a Seedling Heat Mat

    Heat mats are a great tool to use for winter germination.  Heat mats are waterproof and easy to clean, so there is no need to move plants off the mat during watering. The mat is designed to stay on 24hr/day. Ideally, you will want your soil temperature to stay consistently between 65˚F-80˚F. 

    For more precise temperature control these can be used with our digital heat mat temperature control.

    Benefits of Using a Seedling Heat Mat

    Seeds love warm, moist environments during germination. Being able to provide those temperatures earlier in the spring means earlier tomatoes at the market. Want earlier pumpkins? They need to be at least 85˚F to germinate. Heat mats can provide those perfect conditions, increasing growth rates. Being able to cycle through propagation in nearly half the time may mean more crops end up in the ground. Seedling heat mats are also useful in microgreen production.  Add heat mats into your production for more successful germination rates.
