NASA says 5-50 is the optimum range for supporting long term life, I can concur with that as I've attested that ultrasonic fog can support seedlings, 5-20 microns. the HPA covers the rest.

Atomization (>65 pounds per square inch (450 kPa)), increases bioavailability of nutrients, consequently, nutrient strength must be significantly reduced or leaf and root burn will develop. Note the large water droplets in the photo to the right. This is caused by the feed cycle being too long or the pause cycle too short; either discourages both lateral root growth and root hair development. Plant growth and fruiting times are significantly shortened when feed cycles are as short as possible. Ideally, roots should never be more than slightly damp nor overly dry. A typical feed/pause cycle is < 2 seconds on, followed by ~1.5-2 minute pause- 24/7, however, when an acumulator system is incorporated, cycle times can be further reduced to < ~1 second on, ~1 minute pause.

Wow those air atomizing heads from AeroLife are expensive, $155 per misting head, and they're metal, so they're going to corrode no matter what they say, this seems more like something an industry that is subsidized by the people would use and throw away over and over than something that's sustainable for anyone trying to do medical.
I wouldn't recommend those to anyone based on cost unless there's something I'm missing.
EDIT: They're quality, they last a long time before they corrode, however, you only need two of them to do about a 4x4 root chamber. The thing that everyone keeps saying about air atomized is that the fog has a more fog like quality of wafting like fog, vs, the hydro pumps, feeling more like I would approximate it as an ocean spray

While I am not a regular poster, actually I've only posted a few times in the forums I Have followed the HPA and LED cobs closely for years and have several great systems under my belt. While to most people the task of sourcing parts for an HPA system can be quite difficult there are some very easy alternatives for the DIY guru who need an easier and better route.
Root Chamber-
I use two basic setups in my designs, one is the popular commander totes on a short table with drains in the bottom and a rez underneath. This is the cheap and quick setup and a lot of info cna be found on making it.
The Second setup is a completely custom built chamber made from 4x8 plastic sheets kinda like plywood and a rez at the end built from the same. this build is for the serious DIYer and shouldn't be taken lightly. I have seen plywood used and then lined with a pond liner.
the Aero Parts-
First I use a water booster system that can sometimes be bought used on ebay for under $100. I have about 6 of these now because i pick them up at auction for 5 dollars or less and rebuild the pumps.
all of mine use 3/8 ID poly braided tubing which runs about 99 cents a foot at the local hardware store. At the end I adapt it to 1/4 black tubing that is use in RO systems and the likes. I will list the sources for my parts below. most everthing that has to do with plumbing cna be bought at Freshwatersystems and you can call if you have problems finding anything and they will get you squared away.

I forgot where i bought my misters from but I use the same ones from multiponics (purple for cloning and brown for the rest). If i find the original source you can save alot of money on them.
If all else fails multiponics has most everything available except for i make my own timer using arduino
