cold frames for use in tomato growth from seed?

15 years ago

I am starting tomatoes from seed for the first time. I've read that the order of preference for this is:

#1 - greenhouse

#2 - cold frame

#3 - grow lights

#4 - window sill

I don't have a greenhouse or a grow light set-up (although I realize that I can use cheap shop lights for $10), so I would like some more information about how to do it in a cold frame.

I can make the cold frames any size needed, as I will have a bunch of windows coming to me in the next few weeks (parents are replacing windows).

What is the technique for propagation in a cold frame?
