Citadel Starter Kits.

The most important thing is to select the right tunnel for your needs and, very important, the right size. Measure your plot and select the width and height of tunnel.  If you are choosing the traditional method of securing the polythene in a shallow trench around the perimeter of your tunnel, you need to allow for an extra 2' around the tunnel when filling your plot.

The starter kit includes everything you need for your tunnel. Ground fixings, frame, anti hot spot tapes, polythene cover, door frames and hinge door kits. The frames and doors come in kit form. Once the frame is complete, you can measure and correctly fit your frames and doors according to your finished dimensions when the cover is fitted.  Other options such as crop bars and polythene fixing can be selected during the order process. 

Tunnel frames manufactured from galvanised steel tube with a 1.5mm minimum wall thickness.  Polythene supplied with the kits is advanced growers polythene of the highest quality with a 5-year UV guarantee.  Timber supplied for door frames, door packs and rails is treated against rotting.  Hardware is largely manufactured in house and is designed to make the frame extremely robust but simple to construct.
