Growing icebergs with aid of half pop bottle??
Just found your site through Youtube as just decided to grow some veg in pots in back garden.
One of my old friend mentioned as I get really bad black/brown slugs in my garden to cut in half 2lt bottle top and use top part to put over lettuce to stop slugs getting at them. would this work like its own mini green house or just sweat it to death?
