Questiona bout greenhouse covering

Post by Daniel D. Roscig » Tue, 05 May 1998 04:00:00



I am building a small greenhouse for my backyard.  The
plans I have call for the use of "Shade Fabric" as the covering.
Shade Fabric is available from Home Depot and is used for
screened porches etc.  It is like a screen, it does have
holes.

My question is : Will this keep in the moisture, or should I
place a layer of plastic sheeting under the shade fabric?
I am new to gardening and I live in North Central Florida.  The
weather rarely drops below 30 degrees F in the winter, and
can get as high as 110 degrees F for a few weeks in the Summer.

Thanks for your help!

gooday daniel,

sounds more like a shadehouse than a greenhouse, they both have some fairly
significant differences in there use.

the shadehouse is used to protect delicate house plants from the direct sun
and allow them a period of rest outside the house, or to raise young plants
in before getting them sun hardened, so in most  applications a 50% shade
cloth is sufficient.

now a greenhouse is to create a sort of microclimate for otherwise delicate
plants to be raised in, mostly if you want to grow prize orchids, or grow
delicate ferns etc.,. so in a greenhouse you need to control light air and
moisture, and it is only in the greenhouse that moisture can be manipulated
to that degree, the air movement through a shadehouse allows the area to dry
out.

if i can be of anymore assistance please contact me through my homepage

Dan,
        I used shade cloth under my greenhouse panels and it has lasted several
seasons.  Due to the frequent wind and hot hot sun here, we chose not to
put it on the outside.  The high humidity in the greenhouse does not
seem to bother the fabric at all.
