I'm also wanting to make a cold frame......a friend has given me some 2 x 2 perspex sheets - I also have scrap wood from building an arbour last year, will the perspex work or does it have to be glass - look forward to any replies x
There's a video here http://www.youtube.com/watch?v=KIhiCJefPA4 it's one of the clearest set of instructions I've ever seen and certainly one of the most entertaining - anyone who enjoys watching Nigel on Gardeners World will certainly enjoy watching this three times as much!

I'd like to know the answer about the perspex myself actually. I haven't made mine yet as I'm still on the look out for a window frame as I don't want to spend any money....I have some spare wood waiting. I don't know about the heat retaining properties of perspex as opposed to glass and it depends how substantial it needs to be, but it may be worth giving it a try.
Such fab ideas. I chickened out and ended up buying a raised bed kit which was ??24 and easy peasy to put together, and two cold frames! One is glass (only ??10 off ebay) and the other Perspex (new ??80). The second hand glass one is very sturdy and seems to get less condensation than the Perspex one. The Perspex one came in kit form and was tricky to put together but it seems to get warmer than the glass one. Have just moved both off the grass and on to slabs as the plants seemed to be rotting - guessing just too warm and moist on a grass base. Also lots of slugs gathering in the warmth. The raised bed has been great. Nice tidy way to grow veg. How did you get on SkyeSteve?

Yeah, I'll let you know. I'm away for a couple of weeks soon so I'll be planning it while I'm relaxing with my feet up!

The chap in the video mentions that he's also done one on perspex coldframes.

The plants might be suffering from lack of ventilation - it's only in the very hardest weather that you need to keep the cold frame closed up.
