Root-Zone Radiant Heating Help You Maintain Cooler Air Temperatures

Another benefit of greenhouse radiant heating systems stems from their ability to heat the growing medium at the root zone and then migrate upward to surround plants. Think of it like 360° heating that permeates through the blooms and foliage, gently warming all parts of the plant.

When greenhouse heating systems supply radiant heat underneath the crop, growers can also get away with maintaining cooler air temperatures.

Rootzone heating promotes healthy root development, which is why many growers use it for germination and propagation. Plant production also moves along at a faster pace.

A grower with a radiant heat greenhouse can use his heating system in various ways depending on his needs:

• On-bench via rubber tubes spaced a couple of inches apart across the bench. Plant containers rest directly on the tubes.
• Under-bench with round or finned pipes attached to the underside.
• Floor/slab heating uses piping buried in the floor. Sometimes tubes are placed on top of the floor or incorporated into a mat for floor heating.
• Multi-zone heating for individual climate control of different crops in separate areas.
• Perimeter heating running along the outside walls of the greenhouse
• Truss heating installed overhead.
