How is a Polytunnel put up?

What will you need to construct a polytunnel?
Tools needed: A spade, pegs and string for marking out, tape measure, lump hammer, spirit level,
claw hammer, 13mm spanners or a socket set, screwdrivers (pozi-drive), Stanley knife or scissors
for cutting the polythene and a step ladder for reaching the ridge on the bigger tunnels. Drill
(preferably a good cordless) plus 3mm and 9/10mm bits will be required when fi tting doors, frames
and timber base rails. A saw for trimming timber, pencil, gloves, a cloth and a small amount of white
spirit or petrol, to remove grease off the tubes before fi tting the Anti Hotspot Tape.

How is a Polytunnel put up?
You will receive a detailed set of instructions with your Polytunnel Kit, but the following gives a brief
guide to construction.
Mark out position of the foundation tubes or ground sockets, starting with the corners, ensuring
the diagonals are equal. Knock the foundation tubes into the ground, or if using a base rail dig out
for anchor plates or concreting.
Clamps and clips are fitted to the half hoops which are then inserted into the foundation tubes.
Next attach the ridge tube and brace bars.
Door frames are attached to the front and back hoops using the P clips and the bottom ends of the
timber uprights are dug into the ground. Dig the trenches or fit the base rail. Anti Hotspot Tape is
stuck on and then the cover is stretched over. This is attached to the inside of the door frame at each end,
and then either buried in the trench, or fitted onto a timber base rail. It is important to get the polythene
tight, for best results and a longer lasting cover. Choose a warm calm day as the polythene will stretch more easily.
Fit doors, then you’re ready to grow!

If you have not constructed a polytunnel before, you will need to allow time
and have patience. Reading the instructions carefully really does help!
However, if you do have problems we are happy to help..
