I've heard really good things about it, but I'd like to grow flowers in it when not in use for weed. I'm going to keep it on my dining room buffet and try to keep something growing in it, but just for show.
I don't recommend you get this, though, @Matt_auto. It will only germinate a few seeds at a time and it's quite expensive to use for that purpose alone -- it just isn't cost effective. There are more important things to spend your money on... like lighting!
