Heating Cable, 30 meters Key benefits Even, controllable heat for seedbeds and plant propagation areas. Durable construction for long service life and consistent performance. Flexible installation options to match different bed sizes and environmental conditions. Designed for use with a temperature controller to optimize heating efficiency and plant results. Main features Length: 30 meters. Material: construction for durability and reliable operation. Recommended heat density: 80 to 120 W per m2 depending on environment and plant needs. Example: For ZDR100 heating cable set to 100 W per m2, cable spacing should be approximately 8 cm. Wiring guidance: Heat dissipates more at the edges of a hotbed, so route cables closer to both sides. Place the connector outside the bed area for easy access. Control compatibility: Works with automatic temperature controllers. This cable should be used with a temperature controller to improve heating efficiency and control. Why customers need this product Provides stable bottom heat to improve germination and early growth without complex installations. Allows adjustment of wiring density to match plant types and ambient conditions. Reduces the need for repeated manual temperature adjustments when used with a compatible controller. Installation and performance notes Select a wiring density between 80 and 120 W per m2 based on soil type, ambient temperature, and plant requirements. Use the spacing example for ZDR100 at 100 W per m2 as a practical starting point: 8 cm between runs. Run cables closer to the hotbed edges to compensate for higher heat loss there. Position the cable connector outside the hotbed for safety and maintenance convenience. Pair the cable with an automatic temperature controller to maintain target temperatures and improve energy use. Typical applications Greenhouse seedbeds and propagation tables for vegetables and ornamentals. Soil warming for potted plant rooting and cuttings. Smallscale heated benches or hotbeds for hobby and commercial propagation. Compatibility and accessories Compatible with a range of automatic temperature controllers. Multiple controller types are available to match different control needs and setups. Intended to be used together with a suitable temperature controller. Controllers are recommended to achieve consistent results. Practical tips Measure the hotbed area and calculate desired W per m2 to determine cable layout and spacing. Start with the recommended 80 to 120 W per m2 range and adjust based on observed plant response and environmental conditions. Ensure the connector remains accessible outside the bed for inspection and replacement if needed. This 30 meter heating cable offers a straightforward solution for controlled soil heating when used with an appropriate temperature controller.
