AeroJunkie's High Pressure Air-Assisted Hydro-Atomized Aeroponic System (HPAAHAAS)

Atomizer said:

Using a simple baffle to prevent nozzle spatter will only make things worse. You`ll get a river of liquid water flowing off the baffle and the impact of the mist into the liquid film on the baffle will create even larger droplets than the spatter you`re trying to prevent. Its better to have the right mist without any spatter

Can't never could do nothing.

Just trying to save you some time exploring dead ends. If you need to fix the mist after it leaves the nozzle/rotary disc then its perhaps not the best method to begin with.
No point setting design goals if the design doesnt come close to acheiving them. The nutes impacting on the baffle will drain to waste without ever reaching a root, not only a waste of water/nutes but also power as you`ll need to use more mist to make up for the nutes coalescing on the baffle that would otherwise be filling the chamber.

I'm just messin with ya. I believe our tanks are large enough the nozzle can be placed low enough not to be an issue. I'll start a new thread in the near future once we start putting everything together. Trichy is right, I don't want to thread jack this anymore than I already have.

Hey, I just thought as a courtesy to Aerojunkie that we should move this conversation to it's own thread. If it's not too much trouble indrhrvest, I am sure if you start one we will all join in, but not clutter up the thread here. Sorry AJ, you've been quite a good sport...

Hell, this thread was at a standstill for a minute. Its all AA info and that's alright by me, I'm the only one who really takes things off topic anyway. Which reminds me, you think those OKC Boys stand a chance in the finals? Who am I kidding, I don't follow B-Ball.

lol good, cuz I don't know what OKC Boys are... Seriously, I have never watched even one entire superbowl game in my life. I must be communist or something lol... Sports on tv really bore me lose my attention span almost immediately. I don't really watch tv at all though, save for the few discovery and science channel shows once in a while "into the wormhole" anyone?

dude Im the same way my girl is like your a guy why dont you watch sports whats wrong with you lol
while im watching morgan freeman (through the worm hole) or stephan hawkin talk about the universe id much rather watch something educational .

And I thought I was the only one! It usually works out well, cuz most girls only "tolerate" guys and their sports. I'm lucky in that I do like playing PS3, and my girl actually likes playing certain games with me, I love it! We got really sucked into Resident Evil 5, lol...

Oklahoma city thunder. I had to google current sports news to finish that joke... Sometimes I try waaay too hard.

Wormhole is the bomb! Mythbusters is pretty good too. I'm jealous of their ability to acquire just about anything for a build. Everytime i see grant using one of those millisecond timers i can't help but think about mist, lol. I also don't dig watchin sports, weird...

I think the very fact we all have met up here having interest in true aero probably puts us with alot more in common with eachother than the other average joes in the world... It's nice to know I'm not as alone as I figured i was...

I have been lurking here for a long time and hope you post a link here when you do start your own thread......

My first post in this thread. Hello guys. Nice work !!!!

Back to lurking....

Thanks Gyroscope, nothin wrong with a voyeur here... to each their own my friend.

Here's the Hart Environmental nozzles.. Will be a few weeks before I can do any testing. Figured this was on topic if anyone wanted to check them out..

Send one my way, Ill test it for you. What's the retail on them?

I think they are about $80 a pop and $60 for the adapter. They sent these for free to try out. I guess I'm the first person to attempt Aeroponics with their nozzles.

The orifice is really large so I don't see any clogging issues arising with these.

There is not a whole lot of info on their website. Do you have a pdf of the flow rates, nozzle sizes, and pressure requirements? Is this just an external mix impingement nozzle or does it have an internal oscillator?

Yup, that's the nice thing about the aa nozzles, not to mention the compressed air seems it would help blow out anything. We all tend to use clear chemical nutrients with r.o. water anyway, so there's nothing to really worry about unless you wanna use organics which just isn't a good idea and unnecessary with this style imo.

AJ, its what you might call a passive ultrasonic nozzle. The aerolife nozzles use exactly the same principle.
The output from the nozzle impacts on the resonator (the bit that looks like an impingement pin), causing it to vibrate at ultrasonic frequencies which breaks the droplets into smaller sizes. Ultrasonic nozzles tend to create smaller droplets in a more uniform range than standard AA nozzles.

Ok, that makes sense. Have you played with these nozzles in the past? Are they as efficient with air as they claim to be?

Experience with the aerolife is it is air conservative, however the droplets may be too small to grow good roots without alot of trouble compared to what I've seen with some other nozzles. Still testing various paramaters however. As good as tight uniformity in the droplets sounds, I am beginning to think having a range offers some benefits as they evaporate a different rates and distances across the chamber.
