Milk jug cloches........

I've seen clear plastic bottles cut down to make free cloches.
 I don't remember seeing the opaque milk containers that are on sale today used for this purpose.
 The bases are good for free pots, but will enough light get through the plastic sides to use as cloches?
 Anyone used them before?

I fill them with water to weigh down my netting.

One of mine was too bendy too Noshed, but I made the hole a bit smaller in another one and its fine for scooping up the bio-dry!!

I use them - they're fine - I know the frosted stuff you stick on windows lets through 90% of light - I'd guess the milk cartons are probably around the same.

I cut the bottom off, and the neck just where it widens at the handle and use them upside down, and stick 2 pieces of bamboo in - one in main body and one through the handle - that keeps them firmly in place throughout winter.
