Advice on shade cloth...

watzone69

I'm a bit worried about this also. We just moved to this house last November and I've already gotten one nasty letter from the Home Owners Association about not mowing my front yard (hey, it was less than a foot high) soon enough.

My backyard has 6 foot privacy fences too. The neighbors seem laid back but I figure that maybe I should sweetly ask their (as well as th HOA) permission first.

Jorge I think that reads if horizontal, most all WILL come thru.

Something I was told by a commercial nursery supplier along time ago was to use WHITE shadecloth and only that over plants for maximum effect.

Shade cloth is designed to provide shade and also filter light. As most plants, i.e, bonsai, like direct sunlight and as sunlight is white light, then white shade cloth is designed to filter all other colours other than white.

An example of this is two wholesale fern nurseries that I know of here in Victoria.
They use nothing but green shadecloth which gives the ferns green light as they would in the forest under the canopy of trees.

Hope this helps

"Objects can be thought of as absorbing all colors except the colors of their appearance which are reflected."

This would mean that green plants would absorb all light except green. The green in leaves is meant to be from Chlorifil. But does this still mean that plants don't want green light?

This is were I think it gets confusing. Green shade cloth will absorbe all colours except green wich would be reflected. So what colours come through. I would guess it would be high in all colours except green because green would be reflected the most.

White is said to be all light colours reflected and black is all light absorbed. So this infurs to me that black would let through more of all light and white would reflect more and let less light through. Yet colour seems to have no relation to percentage in shade cloth
The percent levels I beleive relate to UV light wich I believe is a yellow light.
Confusing!!

I did a search and found little on the subject.
This site seems to state colour has little influence.

But another had this to say

"Discover the unbelievable properties of Red Shade Cloth. Recent studies have shown that roses flourish under the color red, yielding more blossoms and taller plants with more foilage. Black spots normally seen in the heat of summer disappear. Tomatoes also thrive under the color red. You will be the envy of the neigborhood with your tomato crop.

Blue shade cloth encourages dwarfing and flowering delay. Creates a compact plant with deeper green foilage. Grow more plants per square foot. Also looks great as a decorative touch around your home or pool."


But maybe they are trying to sell the stuff.

Think about it guys.Woven or knitted shade cloth lets light through the "pores"...not through the material itself.The light that comes through is the same light as the light that hits the top of the shade cloth,just less of it.

Tinting a solid transparent surface(corrugated fiberglass perhaps)is a different story.The color of that material would make a greater difference on the wavelengths reaching the plant.
