I often grow clones directly in soil. I'm pretty much a lazy slacker and it's just easy. I often use plastic 'go' cups from my local bar, fill them with soil, poke holes poked in the bottom for drainage, insert my clone and let 'er rip. I cover them with a clear(ish) plastic dixie cup as a humidity cover.
In my configuration, I find this to be the easiest method.
Best 'o luck!
