Emily, that is beautiful. I've grown the Wizard mix too and they do make pretty plants. Last year I overwintered cuttings from those so that I had bigger plants to set out in spring. That little tray of seedlings I showed above are the new Versa series. This is my first try with those.
After you get your indoor lights you should try propagating some coleus cuttings in the house over winter. They're really easy.
