@Arch, can I use plastic lemonade bottle as mini cloches for growing cuttings from plants?
The cover of my proper gator (?) has broken into about twenty pieces after getting blown about by the wind. I cannot just but a new cover. I thought I could cut the base of the bottles off, (and use them for something else), and perhaps make a vertical cut through the bottle, so that the top half fits inside the bottom half, making it more sturdy than a single layer of plastic. These mini cloches would be vertical not horizontal. They would then fit over little black plastic pots, and stand in the base of the old propagator.
