Urban Farmer: * Aeroponics Issue * Hoops go dormant
December 01, 2015
The Urban Farmer, Issue #083* December,
Aeroponics is a really simple and worry-free way to grow and
clone veggies and herbs. Aeroponics is growing vegetation without soil, but the
roots are suspended and sprayed with water and/or nutrient solution. It is a
worry-free way to clone most non-woody stemmed plants from cuttings. You can
also grow plants to harvest in the system as well.
Aeroponics is actually a type of hydroponics. Hydroponic systems come in many forms. Plants may be suspended in the water full-time or they may be fed by a continuous or even an intermittent flow. Aeroponic plants are never placed into water, even for a minute. Instead, aeroponic plants receive nutrients from a mist that is sprayed onto their roots several times an hour.
Growers often support hydroponic plants in net pots or trays filled with a chemically inert media such as perlite, clay pellets, rock wool, sand or gravel. The media is similar to soil in that it holds the plants in place as they grow, but unlike soil, hydroponic media does not provide any nutrients. Aeroponic systems typically employ boards, foam sheets, plastic clips or other methods to suspend the plants in space. No media are used, and the roots are fully exposed.
Hydroponic plants may also hang over a reservoir of nutrients with their roots constantly submerged or sit in a trough where the water flows over the roots regularly. Aeroponic plants never have their roots submerged. Instead, their exposed roots are sprayed three or four times per hour with nutrient-laden water, providing them with just enough water and nourishment to allow them to thrive.
A major concern with both hydroponic and aeroponic systems is any disruption to the flow of liquid nutrients. Some systems, particularly deep-water-culture hydroponics, aren’t much affected by outages. When the power comes back on they pick up right where they left off, though in systems using the nutrient film technique the plants can be damaged if the pumps are off too long. Plants in an aeroponic system are highly vulnerable to outages since there is nothing to keep the roots from drying out. These plants can die very quickly without moisture, often in just an hour or two.

UPDATE ON OUR WINTER GARDEN
Hoops of Hope (Our original Hydroponic SURVIVAL GREENHOUSE)
Well, we decided to let the greenhouse go dormant over the summer rather than fight the Florida heat. So, not much to show this newsletter. Now that it has cooled off some, we are going to start working on the solar panel system, to power up the entire greenhouse, "off the grid".
Stay tuned to follow progress on this project.
