Aeroponics is the lost Russian method of growing plants in nuted, steam, at least the roots anyway
we call it the turkish bath, as thats what you are trying to imitate
its largely replaced by the DWC, deep water culture method,
the real issue with SAM(steam aeration method, thats a first on RIU ??)
is the misters get clogged up with nute salts, the same (used to) happens with DWC,
but they got larger nozzles and better salts than the SAM guys.
Once the misters get clogged the element overheats, and burns out,
no steam to carry nutes to the roots ...shit!
The last I saw this in operation was in Germany 09,
and then the guy was using a commercial feet bath as a test
it too failed, currently we are waiting data from the space station
on how plants are grown in zero 'G' ...for input!
