Suitable for a coldframe?

[Green_Poppy]

Hello

I managed to scrounge some polystyrene boxes. Thought I'd put some clear plastic over the top of these as a temp coldframe. Would it be OK to leave my plants in these to harden off instead of moving them in and out of the house? I would take the plastic off during the day and replace them at around 6 or 7 pm.

Hi

I've moved your thread out of Growing Techniques into an appropriate board.

Many Thanks

Hi Green Poppy, we're heading for July and a heatwave.
What is it you still have indoors to harden off and maybe we can help.
