I wrapped some recycled newspaper around the bottom of a coke can & dipped it in a bucket of water until the paper was saturated. I then removed the paper from the can and there you have it, an instant seed raising pot.
I added a 50/50 mix of compost and fine sand to the jiffy pots, then planted my seeds. The seeds that I used are a bit old so hopefully they will still take. I'm not really sure on the life expectancy of seeds, most packets have a used by date on them but these ones didn't.
The great thing about these jiffy pots is that when your seedlings are ready to be planted out you just dig a hole in the soil and put in your plant, jiffy pot and all.... The roots of the plant will eventually penetrate through the paper, at the same time the paper will break down into the soil... Isn't this such an awesome idea!!!!!
