Great for protecting new seedlings when first transplanted, or when sowing seeds directly into beds. 
Ideal for growing lettuce in cold areas where you need protection from frost. Each cloche is large enough for a full grown lettuce. 

This set contains 3 cloches that you can use over and over. 
They have an adjustable opening top to let heat and moisture out if it becomes too wet inside (eg. lots of condensation - open the vents)
Also includes pegs to hold them down into the soil.
