Shading Device: Sun exposure and Plants

Sun exposure [ Horticulture - Ecology ]
(Luminosity level)


	The amount of sun radiation (light intensity per duration of exposition) present in a given environment that represents a potential health threat to living organisms.

After hardiness ratings, soil and watering requirements one of the most important environmental factors to consider for plants growing is the amount of sun exposure they need or can tolerate.
Light is critical for plant growth and blossoming.

"Full sun" generally means that plants should receive and tolerate at least six hours or more of directsunlight per day given that the most intense sunlight occurs mostly in the afternoon (with a little in the late morning), shadows during these hours have a big effect on how much light plants receive. Six hours of direct sun during the morning is very different from the same six hours in the afternoon. Morning sun, even if it is six hours worth of direct sun is still not strong enough to be considered anything more than partial sun (or part shade) The afternoon sun has a stronger intensity which makes it more powerful.
"Bright shade" An environment that receives between 4-6 hours of direct sun, such as a very bright location with a high, diffuse canopy of trees.
"Partial shade" (Also "light shade" or "half shade") An environment that receives between 2-4 hours
of direct sunn (morning sun and afternoon shade) or a filtered shade through a canopy of shade trees insummer. Species which require some protection from prolonged hot sun, but which will tolerate some sun . Often these species prefer morning sun and afternoon shade.
"Full shade" is an environment with no direct sun exposure or receiving little direct sun, usually less than 2 hours such as a ground among buildings or dense evergreen tree growth which often prevent anything but dappled light from reaching the ground.
