A water reservoir tank is operatively associated with the plant container so that as the plant container becomes lighter as to a loss of water. The adjusting weight member disposed at the opposite end of the horizontal pivot rod from the plant container actuates a valve in the water reservoir tank and transfer water from the water reservoir tank to the plant container until a balance is again achieved. When the balance is reached, the valve in the water tank is again closed.
