Speed up germination and root development with gentle bottom heat from a hydroponic heat mat. Placed under propagation trays, cloning stations and seedling pots, heat mats keep the root zone warm and steady, even in cold sheds and greenhouses. Pair a mat with a thermostat to hold the temperature at the ideal level for your crop and avoid overheating. Heat mats are especially useful for tomatoes, chillies, capsicums and other warmth-loving seeds, and for striking cuttings in cooler months.
