Plastic greenhouse and hardening off plants

[jobnockey]

Just wondering if the young plants i currently have sitting in the plastic greenhouse (its just one of those ones like some shelves with a plastic cover on, nothing fancy) would need to be hardened off before planting out? I know they would need to be if they had been indoors but not sure if being in a flimsy greenhouse counts as being indoors!

Im in SE London if that makes a difference. mainly thinking of some lupins i've grown from bare roots...

They will be getting used to the colder climate now in the little greenhouse. Although I’d wait a little longer before planting out. When you do watch out for frost and just cover them with something like newspaper.

Thank you. I'm itching to start planting out but perhaps I need to practice more patience!

It's not just the temperature. They need to be able to cope with wind too. Put them out during the day in a sheltered area for a few days so they can get used to being blown about a bit.
