What Ever Happened to Fogponics

It is pioneered, but mostly unsuccesful.
A lot of people do use them for cloners, and with good results.
But when the plant gets bigger and needs more nutrients, the droplets a too small to 'carry' these nutrients.
Bigger droplets would be the solution, but....
A. The membrane in the mist maker can't produce bigger droplets, and...
B. Even if it could produce bigger droplets.... would bigger droplets still 'float' like mist/fog? Or would they just drop on the floor due too gravity?

But perhaps there are some new developments.
There are some people telling that they either doing a full grow or starting one.
But you never hear from them again, or they don't have reports or tell any end results.

A guy doing it runs 200ppm with success on YouTube. Seems low...

By the time the 1 micron droplets have coalesced into a size thats useful to the roots the ppm will be a lot higher than 200. Consider the amount of liquid in a single droplet, if the droplet halves in size en route to the roots, the ppm will increase by a factor of 8. Small droplets begin to evaporate as soon as they`re formed ;)

Consider a spherical drop of water as a nute reservoir with lets say an EC of 1.0.
Allow water to evaporate from the droplet until it becomes half the starting diameter. The EC of this smaller droplet will be 8.0 ;)
Halving the size of a sphere reduces its volume by a factor of 8. The nute content doesnt alter cos only the water evaporates so it gets more concentrated. If the fog droplet begins life with a diameter of 1,000th of a millimeter (1 micron), it wont need to lose much water to become a 0.5 micron droplet.

So what I hear you saying if my ec meter pics up anything at all in front of the fogger it would be 8 x the source..

It cant read the ec of fog but if it could it would depend on how much evaporation had occurred at that point. Bear in mind the individual droplets may not evaporate at the same rate.
If you evaporate half the water from a standard hydro res the EC will double. The difference with a droplet is its a sphere, halving the size doesnt just half the volume :).

So Atomizer, are you saying that it is possible to have a decnt yield with Fogaponics?
If so, do you perhaps know where I can find a good report on such a grow?
And I don't mean vertical growth, but a more 'classical' one.
It would be great to see it.

I dont recommend fogponics as the droplet size is too small. TBH, you could get the exact same kind of roots as the ones at 3.50 in the vid above using low pressure aero.
If fogponics worked as well as they claim, the roots would look more like this.

Thanks a lot. As not being a native speaker, I sometimes have difficulties understanding some of the posts.
But you cleared it up.

As many here I was looking for fogponics info. Thread made in 2008. In 2020 this thread is still the most info on fogponics. Lol think i found my answer though. Need to run the fog 24/7 through my pipe for cloning. Thank you all for your thoughts/info. Btw my roots look like that aeroponic systems roots. Cloning was my only issue.
No i dont flower in fog btw. But for fun this is what i made. It goes through roughly 34' of 6in pvc from res. Its a return system.
