Delta-Tub - Model EPDM LD - Rubber Tube Ground (Sand, Soil or Gravel) Heating
Similar in concept to the DELTA-TUBE EPDM SD system, with the same productivity and fuel saving advantages, this hot water heating system with its 4 to 6 inch tube spacing is the system of choice for starter houses. It also excels in the nursery industry for general growing. Growers using this system for heating soil or nutrient bags of tomatoes and cucumbers have shown a 50% increase in yield. Grape growers have found a quicker and more even callusing pattern by using bottom heat to callus grade stock.
