If heating cables are applied in greenhouses or hotbeds, the season of cultivation can be extended. With an earlier start of growing in the spring and a longer autumn many so-called impossible plants can be cultivated and this despite the severe climate.
Earth heating can be arranged in an easy way and without too much encroachment by applying heating cables below the bed of earth. The heating cables are then controlled to obtain the required earth temperature (6-14°C).
General
| Required power: | 60-140 W/m² |
| Cable types to be used: | TCPR |
| Dimensioning: | The power should not exceed 15 W/m cable to prevent a drying up of the roots. |
| Control: | The heating cables are controlled by a thermostat and the sensor is placed in the bed of plants (temperature zone 0-40°C). |
