Rary's probably a good runner as its free - although at his age his free bus pass will be worn out.

In my experience, no physical barrier is effective against slugs.
At best, it may deter them temporarily, but then once it gets wet, or as soon as they are used to it, they'll cross over and eat your plants. And at worst, it seems to actively encourage them.

2 rings of wire around your pot, about 1 to 2 cm apart with a nine volt battery connected across them, so it makes a circuit when the slug/snail tries to cross it, does a pretty good job lol

Okay, fair enough. I can believe an electric fence would keep them away.
