Alright
There are three main types of indoor aeroponics.
Beat it into submission
High PSI Pumps
or
Pressurized system
Most people think about different types of nozzles. The pump defines the nozzle, your wallet and space defines the pump.
Beat it into submission.
Mini sprinkler heads, spinning disks, and tubes with pin holes.
Technically this is not really Aeroponics. It's still effective, but it is hydroponics. The water droplets they produce are quite large in comparison to other methods. These types of systems are usually in small containers or PVC fence posts. This is a bad thing because the purpose of aeroponics is to suspend the roots. a puddle forms when the roots hit bottom and it becomes more of a deep water culture. They use a pump you can buy at wal-mart for under $50. Again not really aeroponics.

High PSI pumps like this one
Ecoplus 250 Pump by Horizen Hydroponics
allow you to use mist nozzles like these
DIG CORP: Series EXL 500 low flow fogger
This is aeroponics, the droplets are very fine. If your roots hang, you will be very happy.
And then there is pressurized systems that have pre pressurized tanks that put out very high PSI. Ultra small droplets, but very costly.
The blue bins are a great idea because they allow roots to dry off in minutes, then they are sprayed again (requires special timer for the last 2 systems)
