The present invention is directed towards an improvement to hydroponic systems using vertical platforms to cultivate plants. A horizontal platform, and system using the horizontal platform, designed to provide for plant growth in a soilless growth medium using an ebb and flow system to cultivate plants within the horizontal platform is provided. The horizontal platform uses a floating valve system to control the amount of fluid cycled through the horizontal grow platform. The present invention further provides for a device that converts a hydroponic vertical tower to a hydroponic device using a vertical tower platform which is designed to circulate nutrients for plant growth in a soilless growth medium and a horizontal platform designed to provide for plant growth in a soilless growth medium using an ebb and flow system to cultivate plants within the horizontal platform.
