Multi Flow Hydroponic Systems

The original Multi Flow Hydroponic System, manufactured by Greentrees Hydroponics since 1992.

We've made many different products over the years, but nothing has come close to the success of our Multi Flow Indoor Hydroponic System.

The Multi Flow system has individual containers for each plant that can be placed close together for small plants and farther apart for larger plants. Moving plants is simple just lift out the inner pot and set it at a new site. No drippers to fool with because the Multi Flow is a bottom feed, ebb and flow system. The pumps fill and drain the pots a few times each day for even watering. Hydroponic gardening at it's best! Multi Flow 12 Pot Systems come with a Built in Timer, 55 Gallon Reservoir, Level controller, 12 Pots, Tubing and Pumps. A 1000 watt grow light is recommended for a 12 pot system.

Multi Flow Systems are available wholesale
