Sorry to have taken so long to get back to you HMR, I seem to get to do one post or so when I get time for the boards. Just not enough time in the day. I've been real tired lately, between the two grows, patients and with Tonto.

The ICMag stuff gets deeper into things cause there is a little more interest there, more players as it were. Fogponics is ok but there was/is not much going on there.

Okā?¦..for a wild ass guess here, I would imagine that if you added 5 micron fog to your EZ cloner that you would need to fog more predominately and only occasionally splash to get what youā??re trying to accomplish.
I do see the air roots form as they leave the bottom of the netpot and then disappear when the roots meet the solution below.
Exaclty correct, I would need to lean on the fog more and lighten up on the spraying. Good observation about the hair roots, they start just below "ground" level and are very delicate. You can wash them away with just a spray.

Well I just picked up a little ā??one lungā? ultrasonic fogger to create a very compact fogger/cloner. Say eight 3.75 inch netpots or possibly just neoprene collars. (Havenā??t decided yet) If I remember correctly the term at Fogponics is ā??on rails or aerorailā? (4X4 or 6X6ā? vinyl posts). Your reply of aero/fog propagator makes me think. I could easily add an airstone on each rail and fog some and splash some. I suppose that would all depend on how long that they stayed in the cloner.
The output of a single head pond fogger is pretty limited but the real problem with pond foggers is the fog produced tends to sit on top of the water. The fog effect only goes a few inches up on it's own. This is the fog we need to get to that area where hair roots first grow, so some type of fan assist is necessary. I was thinking of using 2 single heads in the bottom of my EZ-120s, but then need to blow or suck the fog to where it's needed. At that point I think it is better to make the pond fogger seperate, such as a "bucket of fog" and pump it into the clonner.

For ease on my partā?¦.letā??s say that I built the cloner with the netpotsā?¦ā?¦used the 3.75ā? netpots with lava rockā?¦..do you imagine that the lava rock would mitigate the effectiveness of the fog. Lava certainly doesnā??t seem to stack anywhere near as tightly as hydroton.
Not sure about what effect lava rock would have, it certainly does have more space then hydrotron. I would be comfortable with a fogger like the Frapa to get fog in those spaces but am not sure that a pond fogger would.

I do appreciate the in depth explanation. I gives me something to look for in root development. For some of usā?¦..you really have to ā??spell it outā?.
I really should give credit to the authors of the textbooks and science papers I've read. And I will, some of the best info on roots I got from Clark, Lynn (2004) [I]Primary Root Structure and Developement[I], lecture notes. Heck even the Wiki entry for aeroponics mentions the wilt off problem when going toward aero from hydro! I'm just glad I can regurgitate some of the info I've come across, unfortunately at my age I need to read things at least twice to grasp it and then more is lost then remembered due to poor memory.
Almost forgot (see what I mean) to use an emoticon
