Nutrient fluid is cascaded into the top of this 32-foot tall farm (3 hydroponic towers are hung onto a single wooden mast). Each tower is comprised of 15 plant-growing modules that are removably hung in vertical formation so that nutrient fluid cascades through all of them. Fluid draining through each tower's lowest plant-growing module can be either discarded or recycled back to the top. Preferably, a compost-tea bioreactor is used to brew and pump the nutrient fluid (see further below).

Waterfall Farm's plant-growing towers

The farm's grow-module hoist

The "elevator-pole" is a drill-driven forklift that enables you to easily hoist and hang plant-growing modules onto any of the mast’s hydroponic towers. A Wi-Fi camera mounted on the pole’s moving hoist-arm enables you to easily see, engage and maneuver modules while standing at ground level. Velcro on the pole-stabilization arm located at the top of the mast enables secure operation as well as hands-free tending of the lowered plants .
