at each corner by way of a hinge and a steel pin. These pins are perfect for sliding hollow galvanized tubing over and then cover with plastic film to create mini-greenhouses for season extension. If for some reason a move is needed we can easily remove the pin and relocate the bed to another location. The weight of the frames and the soil holds them on the roof - nothing penetrates into the roof in any way. The beds are 36" x 36" x 8" tall. A hole is pre-drilled at the bottom of one side near the corner for allowing the drip system feed line to run from one bed to the next (a continuous run). Each bed comes with a drip system (see photo above), a bag of "Native Goodness" soil amendment, a 36" x 36" section of 1/4" thick filter/water retention fabric (for the bottom to keep soil mix from seeping out over time, and to hold moisture), and complete instructions. We plan to add a timer and liquid fertilizer in line injector and to purchase galvanized steel hoops to turn these into mini-greenhouses. We plan to position the beds around the perimeter of the roof so they can rest over top where the walls join the roof for maximum support. We also plan to have a waterproof rubber roofing material.

EZ-Flo systems are the effective, environmentally friendly choice for fertilizer injection, or fertigation. With the EZ-Flo system connected in- line from the spigot to the Dripper Irrigation System, liquid fertilizer will be evenly distributed from each dripper directly to your plants’ root zones. The EZ-Flo system features automatic metering of fertilizer for a consistent release of nutrients. Simply add organic fertilizer to the ¾ gallon tank and dilute it with water at the ratio recommended in the instructions. The fertilizer tank connects in-line to the water supply and irrigation system at the spigot using a commercial grade, hose thread adapter. As water flows through the adaptor, diluted fertilizer automatically enters the water supply in a steady, continuous flow.
