Multi Flow 12 Pot Hydroponic SystemMulti 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.

"A couple months ago I got the Multiflow controller (bought standalone). Several weeks later, I finally got it set up with six bucket modules, tubing, rain barrel reservoir, and an outdoor screenhouse, all in the back patio. This multiflow controller works wonderfully!!! Multiflow was straightforward (outright simple) to set up and to fine tune, even when everything but the controller is home-supplied in very piecemeal fashion. It's by far the most quiet hydroponic system I have ever seen, which makes it fantastic for a condiminium patio. And with three supply tube lines that feed 6 grow modules, filling/draining is very quick. The respective pump only needs to turn on/off once to completely fill or drain the modules. This is fantastic. I just realized that I could populate the entire back patio with modules running from this controller. Multiflow is very flexible and fully scalable, and very low maintenance !!! How nice does it get? (grins) I'll send pics when I have vegetable and basil plants that are worthy. :-)"
