I am growing some herbs indoors. My question is about water. Your site mentions setting the container on some pebbles with water for humidity, but is this in addition to regular watering of the soil? How should the water in the pebbles be monitored? Thank you for your response to this request.

The humidity comes from the water evaporating from the dish. The pebbles are to hold the plant pot above the level of the water, so that the soil doesn't stay too wet. The herbs should be watered whenever the top of the soil is dry; the water should run down through the pot, out the drainage holes, and will add to the water in the tray. You can add more water to the tray as it evaporates. You'll be able to see the tray and pebbles, and add water as needed - probably once a day, or even more often.
