What angle should a cold frame be?
Because a cold frame is a passive solar collector the sloping top is best positioned to face south, southeast, or southwest in the northern hemisphere. This will allow the maximum sunlight into the frame during winter when the sun tracks lower in the sky. The slope of the top can vary from 35 to 55 degrees.

Can I use a plastic box as a cold frame?
I was thinking of asking my handsome and able bodied husband to build me a small cold frame when my friend Sally’s husband, Ed, told me that this year he was using a clear plastic Tupperware box for a cold frame. Now turn your box upside down, so so the lid’s on the bottom.
What do you put in the bottom of a cold frame?
In my opinion, the best base is sharp sand, grit or gravel and a good 6 inches deep. That way you can bury or part-bury your pots which means less watering and helps protect from frost over the winter. Thanks very much.
How do I keep my frost frame cold free?
Paint the inside of the frame in white or cover it with aluminium foil. It will reflect the sun rays all day, ensuring enough sunlight. Another thing you can do, is to take a couple of water jugs and paint them black. Fill them up and place them inside the frame during the day so they will gather heat.
Can a cold frame get too hot?
It’s the inside temperature that you need to be concerned with, not the outside temperature. If it begins to steam up, it’s getting too hot. Steam and heat can really stress little seedlings, so keep an eye on them. With a cold frame, the ground is still quite cold and tends to moderate the temperatures inside.
