“There is no gardening without humility.
Nature is constantly sending even its oldest scholars to the bottom of the class
for some egregious blunder.”
WHAT IS AEROPONICS?
The aeroponic system is probably
the most high-tech type of hydroponic gardening. Like the N.F.T. system above
the growing medium is primarily air. The roots hang in the air and are misted
with nutrient solution. The mistings are usually done every few minutes. Because
the roots are exposed to the air like the N.F.T. system, the roots will dry out
rapidly if the misting cycles are interrupted.
A timer controls the nutrient pump
much like other types of hydroponic systems, except the aeroponic system needs a
short cycle timer that runs the pump for a few seconds every couple of minutes.
Conservation of water and
energy. When compared to hydroponics, aeroponics offers lower water and
energy input. When used commercially, aeroponics uses one-tenth of the water
otherwise necessary to grow the crop.
Lush and extremely rapid
growth- quite possibly the most prolific hydro system out there!
Complete dependence on the
aerosol system. When the mist stops, the plants die quickly.
Expense- aeroponics setups are
in general more expensive than traditional hydro setups.

fascinating method? This is probably the best compact system (2’x3′) to get you started:

Hydro Tip of the Month
We recommend only three media for your first hydro
gardens: Coco coir, perlite, and LECA balls.
Could this get any simpler?
*Ebb & Flow: 2″ of LECA at the bottom;
top up with 50/50 Coco &
*The Raft: the nutrient solution IS the
*Dutch Buckets: Fill with 50/50 mix of
Coco & perlite; add 1-2″ of
LECA balls on top to cut down on algae growth.
*Auto pots: 50/50 Coco coir & perlite. No
Tip: Put the LECA balls where the solution
enters the system. This
helps keep the lighter media (perlite & coco) from washing away.
