Mini greenhouse

[TomRipley]

I've been given a mini greenhouse for my patio.
It's tall plastic shelves with a plastic cover so not an expensive one but I'd like to put it to good use.

What can I grow in it?

I start my Dahlia tubers and begonias in a small plastic grow house.
Begonias I lay on compost filed trays but uncovered.
Dahlia I put in pots with just the top uncovered.
They will go in by the end of March and should be ready to plant in larger pots for the patio by the beginning of may.
