Well, there were some things that I did like about my soil mix, and some things that I did not like. So I have decided to modify it a little. I have done some more research, and this is what I have decided that I will try:
2 parts organic humus and manure,
1/2 or 1 part perlite,
1/2 or 1 part vermiculite,
and 1-2 parts peat moss.
I have decided to cut out the top soil completely. It is just too clumpy for my little seedlings. At first I wasn't sure if it would be good to use the organic humus and manure in a potting soil, but after reading up on it, it seems like there shouldn't be a problem. I picked up a bag of vermiculite today, so I will be adding that to my mix.
I have plans to do a lot of experimenting this winter with different potting soil mixtures, so that I can come up with a mix that I am very happy with. What I will be doing is growing a bunch of the same type of plant under the same conditions except put them all in different potting mixes and see which ones do the best. I figure that the best time to do this is the winter because not only will I have the time but, will have the light space to grow them under. I plan to experiment with different fertilizers also, and I will be sure to post all my results. I am excited that I will actually have something to look forward to during winter (I do not like winter very much).
Tomorrow I will try my new mix. I hope that I like it better than what I was mixing before.
