ROOT!T Hobby Heat Mats deliver essential, uniform bottom heat for optimal seed germination and cutting propagation. This waterproof, durable mat accelerates growth, providing a crucial temperature increase, making it a reliable greenhouse essential for year-round success in hydroponics and gardening.
Optimise your propagation success and achieve faster, stronger growth for all your seedlings and cuttings with the ROOTIT Hobby Heat Mat. As a fundamental greenhouse essential and a perfect tool for year-round indoor gardening, the ROOTIT mat provides essential, consistent bottom heat to accelerate seed germination and rooting.
We stock the two most versatile options: the Small (25cm x 35cm, 11W) model, perfect for a single propagator or shelf space, and the larger Medium (40cm x 60cm, 30W) size, ideal for multiple seed trays or a larger propagation area. This durable, waterproof mat uses a fine mesh element to ensure uniform heating, eliminating cold spots and encouraging equal growth rates across your entire batch. Whether you are a hydroponics enthusiast or a traditional gardener, consistent heat is the key to a robust start.
Key Benefits of the ROOTIT Hobby Heat Mat
- Accelerated Growth: Speeds up seed germination and the striking of cuttings by providing an optimal root-zone temperature, cutting days or even weeks off propagation time.
- Consistent Bottom Heat: Gently raises the root medium temperature by 5.5°C to 11°C (10°F to 20°F) above the ambient air temperature, crucial for high-success propagation.
- Durable and Waterproof: Manufactured with a robust, fray-proof matting, it is fully waterproof and designed to withstand the tough conditions of a humid propagator or greenhouse environment.
- Energy Efficient: The low wattage draw for both the small and medium mats ensures economical operation while delivering reliable results.
- Uniform Heat Distribution: Features a tight labyrinth of heating elements to provide even warmth across the entire surface, promoting consistent development in all young plants.
Available sizes:
- Small: 25cm x 35cm, 11W
- Medium: 40cm x 60cm, 30W
Frequently Asked Questions
Do I need a thermostat to use the ROOTIT Hobby Heat Mat?
While the ROOTIT Hobby Heat Mat can be plugged in directly and will maintain a temperature increase above ambient, using a ROOTIT Heat Mat Thermostat is highly recommended. A thermostat gives you precise control over the root zone temperature, preventing overheating and improving overall energy efficiency.How long should I leave the heat mat switched on?
The heat mat should be left on 24 hours a day until your seeds have successfully germinated or your cuttings have struck roots. Constant, steady warmth is necessary to prevent temperature fluctuations that can hinder or delay propagation.When should I remove seedlings or cuttings from the heat mat?
It is critical to remove seedlings or rooted cuttings from the direct heat source immediately after they emerge from the compost/medium. Prolonged use after germination can cause the roots to "cook" or lead to damping-off disease. Once sprouted, move the trays to a cooler area with bright light to encourage strong, stocky growth.What is the ideal temperature range for seed germination?
Most common seeds thrive in a soil temperature range between 15°C and 25°C (60°F to 80°F). However, tropical plants and chillies prefer warmer conditions, sometimes up to 28°C (85°F). You should aim for the specific temperature required by the variety you are propagating.SKU: 1460Free delivery on orders over £60*
