More on my African Violets

hey! Anyone else notice my sudden interest in these silly little flowers? Well I have!

Anyways ... back to my story:

So as you all know I have been propagating African violets in my bedroom in glass containers. They have taken root quite well and I had been planing on just letting them finish growing in the containers of water, but I have been reading on the Internet that this is not good for the plants because they will take longer to root in the soil when I transplant them if they have water roots. Most places on the Internet say that I should transplant them to soil mixtures sometime soon.

Problem is that I have no soil at home, and because it's the middle of winter nowhere local really has the soil type that I need, now I do have sand, but not enough for all 6 of my violets (small as they may be).

For me this is a massive problem and I'm really not sure what to do because I know that I need a really lose and permeable soil to support African Violet growth.

Anyone Have advice for me? I could really use it!

Thanks a lot,
