These BioGreen versatile heatmats are aluminium encapsulated and easily roll up when not in use. They substitute for both spring propagation and heating and winter protection. If you have had problems in keeping your favourite tropical plant alive in a cool greenhouse during the winter (e.g. Heliconia or Plumeria) this may be a solution, acting as a heated bench. The mat is best placed on to an insulation layer, then covered in a sheet of plastic or glass. With the remote thermostat placed in your propagator media or underneath potted plant trays, the temperature is accurately controlled saving running costs in warmer weather.

A soil warming cable is the ideal way to propagate seeds and cuttings on a greenhouse bench. A simple frame can be constructed from wood to form the propagating area required, which is them lined with polythene. The cable is laid onto a 5cm of horticultural sharp sand and covered with a further 5cm of sand. Alternatively the cable can be laid out on to an insulating material like polystyrene sheet and covered over with tin foil then a layer of polythene and then some felt matting to hold moisture under the seedtrays.

The cable is normally laid in runs 3" to 4" apart. This layout will allow you to raise the soil temperature by 11-13 C, above the greenhouse ambient. Higher temperatures can be achieved by laying the cable runs as close together as 5cm. In this case a thermostat should be used to precisely control the soil temperature to avoid over heating.

Please note that the Biogreen cables have a non heated lead flex of 1 metre as part of their cable length ie a 4.3m cable has 3.3m of heated cable and a 6m cable has 5m of heated cable etc.

• Temperature range 0-40ºC (32-104ºF).
• Temperature is measured by an encapsulated thermistor / sensor on the end of a 2.5 metre cable.
• Maximum operating load is 3000w

The BioGreen warming pads are a simple plug-in and go unit that makes propagation easy. The warming pad produces an even heat, raising the soil temperature around the roots by approx. 5 – 10°C above ambient temperature and ideal for improved germination results. This means that excellent results can be achieved even in cooler places.

It is also suitable for propagating cuttings or helping temperature sensitive plants through the winter with a bit of extra heat at their roots.  To save energy it is worth laying a polystyrene sheet or similar under the warming pad. The unit can be used with a thermostat but very useful as a simple low cost solution without.

We offer the most popular sizes (40cm x 65cm Out of Stock) @ 42w, 30cm x 60cm @ 32W for a larger areas and the economical 25cm x 35cm @ 15w
