Front 12

moveable thermal curtain

Back 12

a device that reduces heat loss at night by creating a barrier between the crop and greenhouse roof and walls
p55

Front 13

pad and fan system

Back 13

a system commonly used in greenhouse cooling to reduce the air temp by raising the relative humidity and circulating air
