Heat Mat 500mm x 500mm - 45 watt - Hydro Axis

Boost your plant propagation success with a heat mat designed for cuttings and seed germination. 

  • Warms root area 5.5 to 11 degrees over ambient temperature
  • Increases the success of seedlings or cuttings and improves overall plant growth
  • Durable construction, waterproof and easy to clean
  • Can be placed under any size of seedling tray

Temperature can be controlled via a heat mat thermostat for optimum control if required these are sold separately HERE

Providing the optimum environment can decrease germination time, improve uniformity and increase the number of seeds or cuttings that germinate. 

Critical factors for germination include moisture, oxygen, temperature and light.

Seeds from the packet are at 4 – 12% moisture content. To germinate this needs to be increased to 25 to 50%.  Select a growing media like Stonewool or Rockwool® cubes that has good water holding capacity, adequate drainage and allows good contact with the seed is important.  

Temperature is also important, testing by several universities has found that each species has a range of temperature that is best for germination. For some such as Marigolds, almost complete germination will take place at any temperature between 10°C and 30°C.  Others have a much narrower range, such as Freesia that germinates only between 12°C and 18°C

Light requirements vary with the species, with cuttings light is always required. With seeds once germinated adequate light is required to prevent stretching.
