What % shade cloth do I need? 

See below for our infographic on selecting the right shade cloth.  This is just a general guide, as you can also get some great advice from local growers in your area who know your specific climate better than we do. 

Why do I need shade cloth?

Shade cloths are essential for a successful growing season.  They are usually made of woven polypropylene fabric and can easily be added to any structure.  The main function of shade cloth is to protect the plants.  The light diffusion provided by the cloth is chosen based on the plant's light needs and the local climate. 

Shade cloth not only provides UV protection it also helps keep your greenhouse cool, improves plant ventilation, and reduces water usage.  Plants are able to reduce the amount of excess light energy that they are absorbing which leads to cell damage and often sunburn.

To figure out the sizing, measure the length and width of your structure. When measuring for a greenhouse, avoid going too long and overhanging on the end walls.  The shade only needs to cover the top to the hip-board. The cloth can be attached with shade cloth clips, which have a loop that can be used for tying off with a rope.  Attach the clips on each corner of the cloth and about every 3 feet after that for secure attachment.

How long does shade cloth last?

 Shade cloths are a great investment that when taken care of properly can last up to 16 years.  They help reduce energy usage and increase productivity with less stress being put onto the plants.  Be sure to factor in your plant variety's light and temperature needs when choosing your shade cloth diffusion percentage for best results.

 Does shade cloth need to go all the way to the ground?

No, it does not. It only needs to cover the top above the hip board.

Don’t go too long either and let it hang over the end walls as it might get in the way of your door or vent fan.

Our shade cloth comes with a slight hem on the edge without grommets or clips. A grommet kit can be purchased at box stores or Harbor Freight pretty inexpensively but our shade cloth clips work really well to hold tight to the material with our clips.

They close tight over the material without tearing cloth and have a loop to make it easy to attach a rope or metal bolt snaps or eye snap connectors. Clip them on each corner and about every 3 feet for a very secure attachment.
