Thermal Mat 5W 14 x 15 cm. provides constant and gentle heat under trays and mini greenhouses, perfect for indoor cultivation, germinating seeds and rooting cuttings. Compact dimensions 14 x 15 cm, minimal consumption of 5W and integrated safety for projects with cannabis plants and mushrooms.

This infrared heating mat is designed for cool environments or with nighttime fluctuations. The Thermal Mat 5W 14 x 15 cm. distributes heat evenly across the base, creating a warm bed that accelerates root metabolism and keeps the mycelium active in mushroom kits.
The goal is not to heat the entire room, but to stabilize the microclimate right where it matters: roots and substrates.
In rooms below 20 ºC, the thermal input makes the difference between slow propagation and vigorous development.
The safety system stops heating when it reaches 50 ºC to prevent overheating. It works with a European plug 230 V / 50 Hz and is used under a tray or rigid base, without direct contact with wet materials.
A thermo-hygrometer helps adjust the ideal range (22–26 ºC in the root zone, 23–29 ºC for mycelium depending on the strain). In mild scenarios, it can be combined with a potentiometer or external thermostat to modulate intensity.
Thanks to its small size, it fits in compact propagators, domes, and starter shelves; a reliable ally for starting cultivation with lower electricity consumption and greater control.
Recommended as part of indoor accessories and also for hobbyists looking for cheap indoor cultivation accessories with real impact on the success rate.
In propagation, a warm substrate favors rapid germination and white, active roots. The Thermal Mat 5W 14 x 15 cm. maintains thermal stability under cells, jiffys, plugs, or small inoculated containers. Ideal in cold rooms, starter cabinets, and drafty corners. Also useful in mushroom projects, where the mycelium appreciates a gentle thermal stimulus to colonize evenly.
Key notes: do not wet, do not pierce, do not cover with insulating materials that block dissipation, do not use in direct contact with liquids. The integrated safety system cuts off at 50 ºC to protect the unit.
The Thermal Mat 5W 14 x 15 cm. stands out for its low consumption and great performance in propagation. Affordable cost, energy savings compared to ambient heating, and tangible improvement in rooting and germination rates.
Available at Hydroponics Blanes, trusted Grow Shop with discreet shipping. Easy purchase at online grow shop, with advice for starting cultivation of cannabis plants and a selection of indoor accessories and cheap indoor cultivation accessories compatible with the project.
For those looking for a compact thermal support, the Thermal Mat 5W 14 x 15 cm. offers a warm and stable bed that boosts seed germination, invigorates cuttings, and supports mycelium in cool environments.
Small format, minimal consumption, and easy handling to enhance results in indoor cultivation and propagation projects inside a cabinet or technical shelf.
