ONE-SHEET TUNNELS |
| Row
cover is installed directly over first set of hoops and
often anchored into bed along one edge. A second
set of hoops is installed over the cover at every 2nd or
3rd hoop. Thus, the cover can be raised up through
the dual hoops for ventilation and plant management |

|
|
|
TWO-SHEET TUNNELS |
| Two
half-sheets are installed over the hoops with
their lower edges anchored to the bed soil.
The sheets overlap each other at the top by 3 or 4
inches and are clothspinned to the 16 ga. wire
running the length of each row. External
hoops over the plastic are often added in windy
areas. |

WIRE HOOP SPECIFICATIONS |
| GENERAL: |
Unless otherwise specified, all hoops are made from
pregalvanized wire for years of repeated use. They are formed
into 180 degree arcs. The opening between wire ends
approximates the bed width in the field. The hoops are banded
on both ends with 100 or 200 pieces per bundle then stacked on a
pallet averaging 1,000 lbs. |
| WHEN ORDERING: |
Specify opening between wire ends or provide bed width
and height. Specify wire gauge desired if other tha standard 9
gauge. |
