I started my first grow (which i'm currently on) the same way, but I quickly found that I had to get serious about an indoor grow "system", if I was going to get any sort of yield from the plants. Also found that starting them off growing in the window somewhat stunted their growth, as now they're kinda short, but really thick and full. I'd have liked them to have grown taller, but I'm LSTing them anyway, so maybe I'm wishing for something i didn't really want...

I let them sun grow for about two weeks, and two of them got to be pretty large (for seedlings), but they I don't think they would have grown into something budworthy. Maybe you can do better, but I definately couldn't have.

You might want to invest in a rubbermaid tub growbox setup or the like. it's not THAT expensive to get a decent growbox together, and i think in the long run you'll be much happier for it.

Whatever you choose to do though, good luck and enjoy!
