Abstract
Two different exchange materials, namely corrugated polypropylene tubes and EVA hoses, were compared for heating plastic greenhouses with artesian or well pumped water to improve the precocity of a muskmelon crop.
The water temperature ranged from 26°C to 28°C.

In some of the greenhouses, passive solar sleeves were added to improve the energy delivery.

In all cases growth was better, resulting in earlier yields from one week up to eight weeks.
Total yields were almost the same.
Investment cost was higher with polypropylene tubes but annual charges were nearly the same.
