Soil Warming and Thermostats
Soil Warming Cables
 Soil warming cables provide a safe and simple means of raising the soil temperature in greenhouses and cold frames and are ideal for propagating beds and hot beds.
To provide cost effective and accurate temperature control one of our rod type thermostats should be used. Suggested temperatures are - for hot beds and propagating frames 14ºC - 16ºC and for bench mist propagation 21ºC - 23ºC. A range of sizes is available for both the amateur gardener and the commercial grower.

Soil Thermostats
Thermoforce manufacture a thermostat to suit most applications. These are all fitted with the same capillary thermostat which has a temperature range of between 0°C and 40°C. The rod type thermostats for soil heating have been manufactured for a number of years and following the success of these and to complete the range we introduced an air thermostat which is proving equally successful.
Rod Thermostats
 The rod thermostats are available in two styles as shown, namely the HD908 range which has the thermostat dial enclosed in a waterproof box and is recommended for use where misting equipment is installed and the HD909 range for general soil warming. Both models are available with a choice of three rod lengths. The rod is manufactured from polished aluminium.
HD9082; HD9083; HD9084
 Housed in grey plastic weatherproof box with sealing gasket in lid making this thermostat ideal when a mist propagation system is in use. The temperature adjustment is enclosed within the box and accessible by removing front cover.

Red Neon Indicator. Mains On/Off. Amber Neon Indicator Appliance On/Off.
Grey Plastic weatherproof box with sealing gasket in lid. Temperature adjustment from front of box.
Choice of 3 rod lengths:
HD9082/HD9092 30cm
HD9083/HD9093 45cm
HD9084/HD9094 60cm
Air Thermostat HD9070
 The air thermostat will give accurate temperature control of both heating and cooling appliances. The sensor is clipped to the outside of the box. This however, can be located up to 1.5m from the control box by pulling through the capillary tube and securing with the spare retaining clip which is provided.
