Which type of cloche??

We do have some pipe to make our own (or I might buy a couple as a little busy at the mo), but wondering what to cover with, or which are the best bought one's?
Netting, Fleece or Plastic?

We can't really pop to the allotment to take the plastic one's off on warm days, don't know if that rules them out or if that is not a problem at this time of year.

Primary purpose will be to pretect new seedlings from frost and wind (and maybe encourage them on a bit)

Netting wont protect from frost and wind,  and plastic might too warm on a sunny day, and you'd spend your nice sunny days worrying about your seedlings having a sauna down at the plot.

I reckon fleece is your best option, will offer a little shade from sun, and definitly fend off some of frost and wind.
