FIBREGLASS RODS & ACCESSORIES
- Cloches and growing tunnels
We supply Butterfly clips and/or Ground Staples for fastening Mikroclima and offer four different sizes of Fibreglass Rods for the construction of cloches and growing tunnels.
Mikroclima is the ideal cover for low cost cloche systems, increasing soil temperatures and protecting crops from cold winds, heavy rain, hail, frosts, birds and insects. Because Mikroclima breathes, the problems of extreme heat and condensation that is experienced under plastic can be avoided.
 
A simple cloche may be made by forming hoops from wire, p.v.c. pipe, split cane or fibreglass rod.
Fibreglass rod is the ideal material for this purpose as it is strong, flexible, very smooth and long lasting.
Holes can be drilled into timber pegs or the timber sides of a raised garden to support the rods firmly.
Mikroclima is draped over the hoops, gathered evenly at the ends and tied to end stakes or pegs.
Plastic butterfly clips can then be used to secure the Mikroclima to nails or hooks in the side pegs or timber framing.
 
Fibreglass Rods - Available in four standard sizes.
1.5m x 5.5mm dia. to span a 0.89m width - space 0.8m - 1.2m apart - 50mm holes
2.1m x 6.8mm dia. to span a 1.24m width - space 1.0m - 1.75m apart- 70mm holes
2.4m x 7.2mm dia. to span a 1.43m width - space 1.2m - 2.0m apart- 80mm holes
3.1m x 9mm dia. to span a 1.87m width - space 1.5m - 2.5m apart- 80mm holes
4.1m x 10mm dia. to span a 2.51m width - space 2.0m - 3.2m apart, best covered with 4m wide Tunnet.
 
Ideally a perfect semi-circle should be formed by the rods - achieved by using widths and hole depths as above, thus ensuring that the cover can be pulled tight with even tension at both the top and the sides. Rods may be shortened by up to 5% but should not be bent tighter than a perfect semicircle.
Alternatively, excellent growing conditions can be created by making a half cloche up against a north facing fence or wall.
The ideal dimensions for the construction of a cloche using 3m x 7m Mikroclima and 3 x 3.1m fibreglass rods is:
1.9m width, 2m between rods and 1.1m from rods to end pegs.
MAXI-CLOCHE
The new Maxi-Cloche large format raised crop cover utilises 6m or 8m wide Tunnet over 16mm x 5.4m or 19mm x 7.2m high tensile fibreglass rods. The rods are held firm with galvanised steel ground supports and secured with 6mm polypropylene rope and butterfly clips.
 
These components are all available from Polynet Products for the construction of custom crop protection tunnels.
It should be noted however that the Maxi-Cloche has been designed specifically for low height use and unless quite sheltered any higher structures will be subjected to increased wind levels and further engineering advice should be obtained.
