BELL CLOCHE FROM ACRYLIC INDUSTRIAL LAMP
Found a skip full of these bad boys. They come in a 16″ or a 22″ size.
Last year I had a lot of success with growing climbing plants (eg beans) in a ring of 8 plants surrounded by a 16″ a cut down bottomless pot (large seedling collar). The pot acted as a mechanical barrier against “the onslaught” (slugs & snails). Once the plants established themselves I removed the pot barrier I then fanned them out along a frame.
