A much more satisfactory shading is secured by means of lath slats supported eight to twelve inches above the roof surface.

Most orchid plants thrive best in the kind of shading provided by laths, where moving bands of sunlight alternate with bands of shadow.

Anyone who has seen orchids growing in the tropics will remember that effect of the sun.

The slat shading also efficiently moderates greenhouse temperature on blazing summer days.

An adjustable type of slat shading has been developed that varies the amount of shade to suit the season and can be removed easily for clear glass conditions in the winter (see page 39).

Some growers take an extra precaution against burning by tacking cheesecloth or sheer muslin about three inches below the ceiling inside.

There is some disadvantage in this procedure, however, since the damp cloth furnishes an almost ideal place for the growth of fungus.

The important matter of aeration is next to be considered.
