How long does greenhouse plastic last

Greenhouse plastics are rated with different lifespans. You should not use plastic beyond its lifespan or your light quality will be compromised and your crops will not be as productive. As plastics reach the end of their lifespan, they will have been broken down from sun and weather and will not maintain the stable environment plants need to thrive. 6 mil greenhouse plastic from Berry plastics offers options for 1-year or 4-year use. If you are not a year-round grower and your greenhouse is in a mild climate, you may be able to use a 1-year plastic. However, the best choice for quality and value is the 4-year plastic that will not have to be reinstalled annually (unless your greenhouse site gets very heavy snow).
