This may be a good time to ask local farmers for their used sheets.


I don't know farmers who use them and my garden plots are measured in low
single numbers of square yards, not hectares. And I only have four plots.


Ask your daughter to obtain some and collect it when you next visit?


I'll post the result if my experiments tomorrow.

I have now experimented and the results were excellent. No skill was
required, even the first hole was perfect.

I used a gas soldering iron (so it could be easily used outside) with a
pointed bit. By poking the poly, a round hole about 5mm across was
formed. The melted poly then formed a ring on the outside of this hole
and I believe that this ring would be strong enough to prevent tear-out
(I did not try putting it under tension). Simple, neat, and the join,
once under tension, could be covered with the poly joining tape if a
belt and braces solution is required.

If/when my polytunnel next tears, I will definitely give this a try.
