Advantages
A solution to food insecurity
Controlled indoor environment
Year-round productivity
Minimizes climate change effects
Less use of land, water and energy
Not contaminated by chemicals
Protection from floods, droughts, and excessive sunlight
No seasonality issues
Job opportunities
Nutrient Delivery Systems
Aquaponics
Pros
More marketable to local regions
Don’t have to constantly reset nutrient levels inside of water
Same concentration are consistent nutrients coming through
Don’t have to worry about water changes
It uses organic fertilizers (fish feces)
Save water
Cons
Not many crops available to grow
Initial cost is high
Requires high consumption of electricity
Fish tanks: keep certain temp. 24 hours
Unexpected failure
Should be take care both plants and animals
Aeroponics
Pros
Crops grow incredibly quickly
Yields are high
Uses the least amount of water
Pump and spray system is submerged in the water
Able to deliver short mists of water to the roots of the plants
Cons
Extremely dependent on the misting system
Dried up roots
Plants can die easily
Needs to have backup power
Need to be
checked periodically for clogs
Hydroponics
Pros
Operate big or small the systems anywhere
No soil is needed
Can grow crops indoor even
Easier to operate than aquaponic farms
As there is only one organism to deal with
Income with little knowledge and experience
Can grow specific crops with specific solutions
Save money on water and nutrients
Can overcome the constraint imposed by change of season
Allow to grow in fine-tone temperature and lighting
Plants can grow faster
Cons
Commercial operations can be expensive to start.
Experience and expertise required for large-scale hydroponics
Power and water outages can cause large-scale losses
Boring to people
Not as attractive as aquaponic.
