How much water is added in each container?
There is no fixed amount of water in containers. I add anywhere from 1/2″ to 1, sometimes just a little more but usually below 2. It all depends on the height of the container and how low the roots are situated. Just keep the water level below the roots. If you are uncomfortable with clear glass containers and the single pot method, consider using the standard double-pot method used in hydroculture that comes equipped with a water level indicator. Visit Houseplant Hydroculture to learn how to make your own water level indicator if you cant find anything locally.
