NOTE: IF THE POLY IS
INSTALLED ON A COOL DAY, IT
MAY EXPAND AS THE
TEMPERATURE WARMS
CAUSING IT TO DROOP. IT MAY
BE NECESSARY TO RETENSION
THE SHEET OF PLASTIC AT A
LATER DATE.

For structures without side wall ventilation, proceed to
INSTALLATION OF GROUND TO GROUND POLY page
11. Wiggle wire will be installed in the same Wiggle Base
as the Roll-up Curtain from page 9.
Try to pick a calm day. If it is windy, it's almost impossible
to handle the plastic.
Lay out the wiggle wire around the perimeter of the
structure so they are handy. Unroll the poly on the ground
along the length of the structure. Be sure you have equal
overhang at both ends of the greenhouse.
Place one worker at point A and point B . It helps to
have another worker inside the FieldPro at point C , on
a ladder, to help carry the poly over.
Once the poly is in position, begin installing wiggle wire
sections at point 1 . Complete this side of the greenhouse,
using the edge of the poly as a guide. (3" to 6" overhang
is adequate)
Go to the other side and install a wiggle wire section at
point 2 (center), and fan out from there. Complete this
side.
HELPFUL HINT: To avoid poly drooping between bows,
instruct a helper to tension poly one section away from
person installing wiggle wire. You will notice the wrinkles
disappear when this method is used. When the person
who is installing the wiggle wire meets the person
tensioning the poly, the tensioner can move to the next
bow.
Also, after all wiggle wire has been installed, using a blunt
object, press all wiggle wire firmly into base to ensure it
has been seated properly.
Then, starting in the center of the end hoop, 3 , begin
installing wiggle wire sections down to point
4 . Go back to point 3 , and install wiggle wire sections
to point 5 . Do this on both end hoops.
After this is done, cut remaining pieces to approximately
12" lengths. Use these in the corners (dotted lines) to
reinforce the top cover and end poly. FIGURE 1
