Propagate all your new seedlings using Seedling Heat Mats to ensure the perfect environment for newly established root growth, plant cuttings, and germinating seeds. Heat mats are designed to reliably warm the root zone between 10-20˚F above ambient air temperature.
Available as a Master or Add-On unit to allow for daisy chaining. ****You must have a master heat mat to use an add-on.***
Usable with our digital heat mat temperature control.
Heat mats are a great tool to use for winter germination. It is ideal to use SunPad Heat Mat Controller with the heat mat for more precise control. 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. Connect multiple mats by daisy-chain connecting add-on mats. Ideally, you will want your soil temperature to stay consistently between 65˚F-80˚F.
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.
