This is an excellent fall and winter, fabric that is 1.25 oz with 60% light transmission.
Can provide 4 - 6 degree frost protection. Plants do just fine under this fabric even with the reduced light transmission.
Be aware that this grade of fabric can build up heat if temperatures and sun are optimum.
Directions:Row covers are best use over crops with support hoops to hold the row covers over top of the crops. There are many different types of fasteners that are sold on the market to hold down the ends of the fabric but we recommend using any of the following: sandbags, pots filled with soil, pipes or wood. We sell a row cover support that works great over crops, link here.
