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.

 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.

Hydro Tip of the Month- Them lamps are



biggest obstacle to a successful hydroponics garden will be…..

heat. The lights needed to grow veggies

are hot!

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

65-80 degrees.

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.
