I purchased the MistKing system, the heavy duty Misting pump and the interval timer. The system has worked flawlessly and it was a snap to set up once I found out how to insert and remove the tubing in the fittings. Piece of cake! I use it for light watering and humidity control in my Wardian Case for orchids. It mists for 5 seconds every 4 hours during the "lights on" period. At that rate I refill the water reservoir after approx 3 months of use. I never worry about leaving for a week at a time and will the system fail me. Thanks for the great service and help.
