Warmth is a requirement when it comes to germinating seeds. When gardening indoors or out of season, it is often outside of the desired temperature range needed to start the germination process. Using a seedling heat mat, you can replicate the warming of spring that sends seeds popping to the sky.
What Is A Seedling Heat Mat?
A seedling heat mat is an electric mat that is placed under your seed or cutting tray. It will typically warm the root area to anywhere between 10-20 degrees above the room temperature.
How Do You Use A Seedling Heat Mat For Seed Germination & Cloning?
- Start off by finding a stable surface. Make sure you place the mat somewhere away from water and hydroponic reservoirs. Water and electricity do not mix. Avoid placing on a cold surface such as a concrete floor. This will direct the heat more towards the colder surface and less towards your seed or cutting tray.
- Place your clone or seed try on the seedling heat mat and plug it in. The heating mat will heat up 10-20 degrees on its own and stay in that range. There are also outlet adapters you can purchase that monitor the temperature then will automatically shut on and off to stay in the desired temperature range.
- Place a dome over your seedlings or cuttings. This will help to retain moisture, raising the humidity, increasing the success of germination and health of root production.
- Remove tray from heat pad when roots begin touching tray. Be careful not to overheat the roots and damage the plant.
