I cover it with old silage sheet and make holes with a blow lamp. The sheet melts back to produce a hard ring and a nice clean hole to plant the veg through. Actually that's not a bad idea - for a veg patch. I might (albeit reluctantly) follow your example :-) This may be a good time to ask local farmers for their used sheets. They should now have cleared their silage and they will have to pay to have the sheets removed. Someone offering to take a sheet off their hands for nothing will be welcomed. However, I think that such holes might be too large for a polytunnel lacing repair. You haven't seen the size of the laces. :-) I'll post the result if my experiments tomorrow. -- Howard Neil |

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. -- Howard Neil |

How about you picking up a bit for me, I'll collect it in July? Mary |

Congratulations, Granny. :-) I'll post the result if my experiments tomorrow. How about you picking up a bit for me, I'll collect it in July? I've already had my neighbour's plastic (the only one I know who has a silage clamp). The others all use silage bales. :-( -- Howard Neil |

The south-east corner has perhaps 1/3 the pull-through strength of the north-west one. |

Mind you, that sounds a real challenge to the system. I have a replacement cover, which is going to be put on at some point. Replacing bits would be slight overkill. However, on one end, it's probably going to get the old cover moved inside, to form double glazing. |

If you could get some bubble wrap, you could perhaps put it between the two layers of poly and improve the double glazing effect still further. -- Howard Neil |
