Grommeted Panel (currently viewing)

The edges of these panels are sewn with heavy-duty reinforcing tape. Brass grommets are installed on approx. 2' centers around the perimeter. Often includes a seam where two pieces of shade have been sewn together. Durable, easy to install with ropes, bungees or wire. Most durable solution for smaller areas where shade will be suspended between four points. Grommeted panels are sold in pre-cut sizes or can be ordered in any custom size.

Precut Panel

A raw piece of shade fabric where edges of panel are not reinforced with any tape or grommets. Would not typically have a seam but may have a raw (cut) edge. Can be installed with wiggle wire, shade cloth clips or wooden lath. Precut Panels are sold in pre-cut sizes or can be ordered in any custom size.


Sold in factory widths by the linear foot. Would only rarely have a seam and sides typically include a factory finished (uncut) edge. Most cost effective solution for large quantities of shade fabric.

  • Fabricated pieces include black reinforcing tape on all four sides. Reinforcing tape is a seat belt like material that provides extra durability along the edge of the piece and allows installation of grommets.
  • Fabricated sizes include a brass grommet in each corner of the piece and approximately every 2' apart around the entire perimeter. Grommets allow easy installation using rope or zip ties.

Hanging Instructions

When hanging shade cloth pieces larger than 100 sq. ft., you may need extra center support to prevent the cloth from sagging in the middle. One easy way to do this is by running lightweight cable from corner to opposite corner, forming an X pattern that the cloth can rest on. For pieces larger than 400 sq. ft., you may need cables running end to end every 4' or so.

  • Nice and sturdy
    I bought 40% according to GMS referrals. It looks like still too bright for Texas weather. However, my plants are happy and they start producing new leaves and flower within few days of use the shade cloth. This is somewhat shaggy as it is stitched. I used PVC pipe to make arch across the raised bed to support the cloth. So far looks fine
  • Very Pleased
    Tight smooth just what I needed !
  • Saved my nightshades bed
    I have 4" x 16" raised beds enclosed with t posts and deer netting. My nightshade bed was suffering from sun scorch until I installed this shadecloth with zip ties over criss crossed clothesline. This week I added a second one to another bed with winter squash.
  • Working so far
    Fits our greenhouse good. Have only had it on for about a week. Works good so far.
  • Quality is Good
    This is my 2nd shade cloth from Greenhouse Mega, the 1st shade cloth lasted about 8 years in the Southern AZ Sun and Wind, which I am very pleased with. These are lightweight, but the 1st one held up great... We'll see if the 2nd is up to the same task.
  • very well made
    This arrived and we were pleased with the quality of the product. We have been using it and not found any defects I workmanship or basic materials. Very good price. Excellent handling/shipping.
  • Shade cloth
    Easy to install. Keeps tomato plants cool in 90 plus degrees. Plan to order another for next growing season.
  • 40 percent Black Shade Cloth, Grommeted Panel
    I received one of the shade cloth which is doing good at shading my small garden. I ordered another larger shade cloth that I have not received yet. I ordered it on May 27th and today is July 11th. Would have been rated a 5 if I had both items ordered
  • Made a huge difference
    I purchased the 40% shade cloth on a recommendation from a friend. I already had windows and a fan but it was still too hot to use during the summer. Now, I can grow basil, tomatoes, etc without it being too hot. So glad that I purchased this well made shade cloth.
  • Stronger than it looks
    I purchased a 20x24 piece of this shade cloth a few years ago and have used it to cover the top of a greenhouse to protect the plants from a little white butterfly that lays eggs that turn to worms that eat the flowering parts of the plants, It guards against the butterfly while letting in all the sun the plants need.
  • Great!
    Performs as advertised. Well sewn seams edges and grommets. I am using this to provide shade in my chicken run. I will use this product again.
  • 40% Shade cloth
    The shade cloth has allowed me to start veg plants outside for the first time. Our temps can shoot to the 90s in the spring but with our 40% shade cloth I've had nothing but success! My husband appreciates the sturdy construction and how easy it was to put in place over the greenhouse he built for us this spring. Thanks for the great product!
  • Shade Cloth
    I found the shade cloth to be high quality. Metal rings every 2 feet and double rings at corners. Already went through several 40 mph wind days with no problems. I think for summer days I would prefer 50-60% shading for my area.
  • Great Product!
    Really a top notch product! Quality is outstanding and the sun shade for the garden is perfect. Purchased the 40% sun block and the veggie garden seems to approve.
  • Sun shade for vegetable garden
    The 40% sunshade is very effective at cutting down the blistering sun, and our garden has been doing very well since it has been installed. For Souther California I wouldn't use a lower percentage, as 40% feels like it is the minimum shade. For sensitive plants I would concider 50% to 60%
  • Just what I needed.
    I put the shade cloth on my hoop house. It's perfect. Perfect fit, good quality. It's just what I needed to shade my young plants.
  • Exactly what I needed
    Provides just the right amount of shade to keep the hoop house cooler yet not block too many lumens.Quality construction.
  • Shade cloth
    My 40% 20' x 20' shade cloth arrived prior to the estimated date. It was beautifully bound as requested and the exact size as ordered, so thanks for your excellent workmanship. It was easy to install and has dropped the temp in my 10' x 20' hoop house by approximately 15 degrees - which is wonderful. I feel that if I had installed roll-up sides on the hoop house, the shade cloth alone would have taken the 125 degree temps (prior to the shade cloth) down sufficiently; however, only a door on one end and a window on the other apparently is not enough ventilation to maintain a reasonable 80 to 90 degrees. With the addition of a tarp over the top, the temps are maintaining 80 to 90 degrees, but the amount of sunlight is reduced. I'm still learning and experimenting while considering modifying the hoop house to include roll-up sides, but aside from that I highly recommend the shade cloth!! Thanks!

  • 40% shade cloth
    The best!
  • owner
    The webbing shade cloth was not fully tucked in to the sewn edge in two locations. After tying it to top of greenhouse and pulling it slightly taught so wind would not buffet it we noticed it came out in a couple of places. Don't know if it will come apart with time or not. We'll see. To much trouble to take all back down again.

  • exactly what I was looking for!
    My packaged arrived within a few days. I was so excited to have found greenhouse megastore. It was to be in the mid 90's for a few weeks. We got our 16 x 24 foot 40% shade cloth and put it right over our greenhouse. It fit perfectly! The temp stays around 90 wirh fans on. My plants are happy, and I am thrilled. No more 120 degrees!
  • high quality product
    I installed the 20 foot by 48 on outside of our double layer greenhouse. and it has grommets around edges. great price and installed great. Wind does not get up under and it holds against plastic great!!! Have had it installed for a month and in high winds performs great!!! highly recommend this...
  • Great shade
    I was needing to reduce the heat in my greenhouse. Air circulation alone was not enough. The 40% shade cloth was just what the doctor ordered. It is light weight, easy to install - make sure there's little or no wind, and reduces the inside temp by at least 20 degrees.
  • Shade Cloth 40% Black
    Exactly as advertised. Quality and construction excellent. First time to use so will have to see how it holds up in Texas Sun, Heat, and Wind. So far it looks like it will do the trick to protect our veggies! Will probably order exact fit size next time as 16x20 was a bit too long.
  • Brass Mat
    I use this as a net to catch brass at the range. We can get some press good gusts of wind so It needs a little weight. The 40% works great.
  • Good as expected
    Product was very similar to last shade cloth that lasted ten years in our intense sun and heat. Shipped very quickly, arrived in a few days. Excellent service. Cloth strong, does not rip, border very good.
  • 40% shade cloth

  • Outstanding!
    Couldn't be happier with the product or the service. Our shade cover was used to cover our pergala in the harsh Nevada sun. Also it withstands the harsh winds also. Now we enjoy our courtyard everyday!
  • Another Shade(y) Customer!
    This product works perfectly for the 2 small greenhouses I built in my backyard. Not only does it do the trick for shading when needed, but it also protects against hail when we have major thunderstorms here. The item arrived on time, it is exactly as described and I have yet been able to put a hole in it!
  • shade
  • Good service
    Product as advertised. Very quick delivery time. Will come back for future orders.
  • Better than I thought
    Material is very strong. I used it on the front side of my greenhouse using ties and clips. It lowered temp another 10 degrees.
  • 40% perfect for Zone 5
    I would definite buy this again. It allows air flow, is strong against wind and could be cut and sewn if needed, or just cut, no fraying. I bought 40% and that was perfect for my zone 5 location.
  • Sun shade 40%
    Product was as advertised and shipped promptly. We are having a drought in Texas and this product saved my garden just in time.Thank you
  • 40% Black Shade Cloth
    I had installed the ribs for a 12' x 36' hoops to make a small shade house. The fabricated 20' x 36' shade cloth fit perfectly! Very pleased with the quality and quick shipment. I will be purchasing additional shade cloths in the near future from IGC due to this online experience exceeding my expections!
  • 40% shade cloth
    It seems to be everything that it's claimed to be & delivery was very fast
  • Impressed
    As stated, this lowered the temperature in my 10x12 greenhouse by 20 degrees. My seedlings are doing much better. The finished edges are great and I was able to put it on my greenhouse all by myself.
  • excellant product
    I have seen big improvements in my plants since I started using your 40% Black Shade Cloth - I think its a good product for me.
  • wildflowerhoney
    Great shade cloth. Easy to work with; tough; won't tear; yet flexible even to go where you want it. Nice that plants can be seen through it and the rain and water goes through it; it does soften the blow of beating rain, too, so the lettuce doesn't get crushed or beaten down. Very convenient size and excellent price. Can't wait to see if it extends my lettuce harvest into the summer here in the tropical south where climate change has made the summer heat torrid and seemingly lethal for most crops.
  • shade cloth
    This product cooled my vegetable garden from the hot Florida sun. Great value!
  • Good Value
    I was pleasantly surprised at the quality of this product for the price I paid. Very functional and easy to use. Will need to see how well it holds up under an extended period of sun exposure.
  • SC-BL40
    Shade cloth is good quality. I like the idea that it is knitted and wont ravel.
  • SC-BL40
    This product is lightweight & well sewn! Very happy!
  • Excellent product!!
    I purchased this shade cloth to help reduce how warm my 9' by 12' custom built hobby greenhouse... day time temperatures with side ventilation and exhaust fans was 40+ degrees Celsius on bad days... now with the shade cloth it has reduced it to a more livable 28 degrees Celsius.. cloth went up in a snap and was cut exactly to the size i wanted and gourmets and taping was perfect all the way around...
  • nice addition to my easygrow greenhouse
    This is a nice product. Just what we expected. We stretched it over my easygrow plus greenhouse to lessen the suns rays on and around the greenhouse area. works like a charm.
  • 40% shade cloth
    I used this shade cloth to cover tomato's. Once covered they started to grow with vigor and are produce many more flowers and there for many more tomato's.
