Under-Bench Heating for Rootzone and Canopy Heating
A study published in California Agriculture by professors Bryan M Jenkins, Roy M Sachs and Glen W Forister showed that conductive bench heating systems used 25% less energy than conventional perimeter heating systems. This same bench heating system maintained even canopy temperatures around the plants and resulted in fewer hot and cold pockets. The study found that bench heating produced consistent output in and around the plants where it was needed most with less input.
Under-bench heating systems are ideal for providing consistent heat across the width of your greenhouse benches. The mix of radiant and convection heat means that both the bench itself and the air surrounding the bench are heated evenly all around. So not only does your rootzone get a boost in temperature which improves water and nutrient absorption, but the canopy stays protected from temperature fluctuations as well.
