I have been wondering for a while how to best water my plants. as of now i have them in modified 2 liter bottles with holes for drainage, sitting in a disposable baking pan to catch the water. to me this seems messy, and incorrect. How do you guys water your indoor soil plants and deal with the drainage? Also, how would you handle the drainage of a pot like Hobbes' Air Pruning pots? i want to make some, but scaled down.
