Our polytunnels don't use the
traditional steel support hoops. We prefer 2" normal gague water piping - its flexible and strong.
We drive 2" galvanised scaffolding
tubing into the ground at 5ft centers on both sides of the tunnel.
The hoops are slipped over the scaffolding tubes and bolted into place.
The hoops are then joined with
lengths o 2x1 timber for the full length of the tunnel.
The ends of the tunnel are constructed including the door frame.
If the raised bed option is required they are fitted at this stage.
The cover is now placed over the tunnel and secured.

This is a general purpose UVI/EVA
film for use with all hardy stock. This film is actually stronger than
conventional 720g films, but offers significant cost savings, whilst
incorporating an infra red filter (HDF) to slightly lower the daytime
temperature. The HDF also gives 62% scattered light to reduce shadows from the
structure so that the plants grow more evenly.
This is a 720g thermal AF anti
botrytis/mildew and heat reduction film for use with all heated crops, sun
loving stock, propagation houses, and over wintered vegetables. The HDF filter
produces 62% scattered light and lower daytime temperatures as with Superclear
HDF. The addition of UVA and UVB filters reduces many fungal diseases like
mildew and botrytis, whilst the thermic anti-fog additives can give up to a 2deg
temperature lift on a frosty night and dramatically reduce the amount of
condensation on the film. A top of the range film offering significant benefits
to virtually every grower.
