This is the 70 percent shade net we supply for greenhouse vegetable growing. Seventy percent is the rate growers reach for on leafy crops, because it cuts the afternoon sun load enough to stop leaf scorch while still leaving the plants the light they need to size up. The knitted HDPE mesh stays open, so hot air lifts out of the house and rain still reaches the beds rather than sitting on the cloth. It rolls on and off the frame without gear, which suits a house where the cover is adjusted through the season. Shade rate is made to order across the range where a lighter or heavier cover is wanted.
Shade rate is the first decision on a vegetable house, because it sets how much light the crop keeps. Seventy percent is the rate most growers reach for on leafy crops, and this is the net we run at that rate in a knitted HDPE mesh.
Seventy percent cuts the afternoon sun load hard enough to stop leaf scorch, while still leaving the crop enough light to size up. That balance is why it is the standard rate on leafy greens, herbs and young plants rather than the heavier cover used on a structure that only needs the heat cut. The knitted mesh stays open, so hot air lifts out of the house and rain still reaches the beds instead of sitting on the cloth and steaming the crop underneath.
The net goes over greenhouse roofs and frames, across leafy beds and over nursery benches where young plants need the sun load softened. Because 70 percent suits both a leafy crop and a seedling bench, the same roll covers the house and the bench rather than two separate weights. Growers running pots under the same cover often pair it with a planting bag, and the wider shade net range covers the reflective and coloured types where the job calls for something other than a plain green cloth.

Seventy percent is the working rate for leafy crops, and the rate is made to order across the range where a heavier or lighter cover is wanted. Span is the second choice, since the net has to cover the house or the bench rather than a single row. A knitted monofilament net covers the same idea where a finer weave is wanted, while this net covers the standard vegetable and nursery job. Growers often hold one roll for the house and use the offcut on the bench.
Width, length, shade rate and colour are all made to order, so the first detail to confirm is the span of the house or the bench you are covering. Rolls ship in export packing and are cut to suit the frame. Growers tracking how shade netting performs across a season can follow trade coverage such as HortiDaily and FreshPlaza for what is being installed on commercial sites.
Why is 70 percent the usual rate for leafy crops?
It cuts the afternoon sun load hard enough to stop leaf scorch while still leaving the crop enough light to size up, which is the balance leafy greens and herbs need.
Will the net let rain through?
Yes. The knitted mesh is not coated, so hot air lifts out of the house and rain still reaches the beds.
Can I order a different shade rate?
Yes. The rate is made to order, so a lighter or heavier cover is produced where the crop or the site calls for it. Tell us the crop and the site and we will advise.
Tell us the span, the shade rate and the colour you are working to, and we will confirm the width and the packing that suit your order.
