Urban Farmer: * Aeroponics Issue * Hoops go dormant

Hydroponic Garden: What is Aeroponics?
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
solar panel system, to power up the entire greenhouse, “off the grid”.
Stay tuned to follow progress on this project.

heat. The lights needed to grow veggies
If you’re growing inside, you need to think about this. Any garden prefers a
cool climate to an overly hot one. The magic numbers: keep the temp between
Here are some ways you can cool things off:
*Crack the window open in cool/cold weather.
*In winter, close off some of the heat getting to the growroom.
*Use a fan to blow heat away from the plants.
*Get a grow-light equipped with exhaust tubing & inline exhaust fan.
*Keep A/C thermostat at 72-76°. Can’t afford
Buy a portable A/C or small window unit for your grow-room.
