Many greenhouse growers, both new and old, have a lot of questions on what are the best options for covering their greenhouse. This short video by Dr. Gene Giacomelli (Professor of Agricultural and Biosystems Engineering and Controlled Environment Agriculture at the University of Arizona.) and Dr A.J. Booth (Extension Specialist in Horticultural Engineering, Energy, Hydroponics at Rutgers University) does a great job educating and informing growers on the basics of greenhouse glazings.
