What is it?
Aeroponics is a sophisticated plantgrowing technique ideally suited to a
range of purposes, particularly the
growing of disease-free seed crops and
high-yield greenhouse. Aeroponics
uses no soil or liquid medium, just a a
small internal microjet spray that sprays
the roots with fine, high pressure mist
containing nutrient rich solutions.
How does it work?
Types of Aeroponics
• Low-pressure units
-
the plant roots are suspended above a reservoir of nutrient
solution or inside a channel connected to a reservoir.
• High-pressure devices
-
High-pressure aeroponic techniques, where the mist is
generated by high-pressure pump(s), are typically used in the
cultivation of high value crops and plant specimens
• Commercial systems
-
comprise hi-pressure device hardware and biological systems.
The biological systems matrix includes enhancements for
extended plant life and crop maturation
Benefits of aeroponics
1. Less Nutrient Solution Throughput
-
The time spent without water allows the roots to
capture oxygen more efficiently
2. Ecological advantages
-
safe and ecologically friendly for producing
natural, healthy plants and crops
-
conservation of water and energy
3. Requires little space
Benefits of aeroponics
4. More user-friendly
-
aeroponic system allows ease of working with the plants
-
separation of the plants from each other
5. Pathogen Control & Disease Prevention
-
applies disinfectants and fungicides to the aerial and root
zones individually
applies the water/nutrient at intervals that are best suited for
plant development and growth
-
allows the plant to expand without interference of restricting
physical barriers
Benefits of aeroponics
6. High efficiency
-
highly efficient in terms of water, nutrients, energy, and space
7. Fast plant growth
-
their roots have access to a lot of oxygen 24/7.
8. Easy system maintenance
9. Mobility
-
Plants, even whole nurseries, can be moved around without
too much effort
Disadvantages of aeroponics
1. Technical knowledge required
-
certain level of competency in running an aeroponic system
2. Dependence on the system
-
plants can be damaged or killed easily if any part of the
system breaks down
3. Regular cleaning of the root chamber
-
The root chamber must not be contaminated, or else
diseases may strike the roots
4. High cost
