I want to grow some herbs on my window ledge for use in cooking, and I've heard about using open top glass jars as the pots. I'd be growing these from the seed and won't be moving them outdoors due to the abundance of cats that like to mark their territory everywhere.
Can any one give me some advice on what to do or look out for or problems that may arise?
I'm aware of drainage issues due to the lack of holes inside the jar - how can this be overcome? (Other than not over watering, of course!) I've seen sites discuss placing sand and pebbles at the bottom of the jar to create some form of artificial drainage, but would this be sufficient and if so, how best would this be achieved?
Or perhaps, would it just be more reasonable to use normal and standard pots?
