Our convection tube is made of an upgraded 4 Mil strong virgin polyethylene with high clarity and a special blend of additives. It is also FDA approved.
It is designed to last one season, although generally being installed in a greenhouse underneath two layers of polyfilm, it can last as long as two years.
For 18", 24", and 30" diameter tubing, the punched tube is the multiple vent, staggered rows, allowing for better air distribution and circulation within your greenhouse.
