HP Aeroponics nozzle help

My partner and I recently put together a system and we are looking to test out a couple different nozzles in our system to see what works the best. I have looked around here a lot and I hear a lot of different things, but we were looking for some advice on which ones to look into for 80PSI, or up to 100psi if needed. Though it seems 80PSI is the sweet spot. Are the stainless steel ones which are more like $15 a nozzle worth it? Will the plastic ones do the same job and last? Can someone give me a few good ones that are generally accepted to create a really good fine "mist" for misting a root chamber of 26"x17.75". Also how many do you think it would take to cover this area? Being economical is important but it will be most important to get the best amount of nutes to the roots as possible for the best results in the plants.

Another question would be does anyone know the formula or have some knowledge on how many nozzles can be used while maintaining constant pressure per size accumulator at 80psi with a fairly standard on/off cycle? Also what is a fairly standard timing?

I know a lot of this information can be found by searching the forum but we are trying to actively post here to become involved in the community and also I myself am fairly new to forums in general so please don't hate! <3

Welcome!

Did you read the thread "True HP Aero for 2011" started by Trichy Bastard? If not I strongly suggest you read it. It will answer all your questions.

Peace

i found treefarmers thread to be much more info dense. and its shorter too.
hes also the only person i know of to publish pictures of the roots i desire to be able to grow.
with exception of g loves atomix grow over on uk420

he used the biocontrol nozzles with an orfice size of 0.016".
i am going to be transforming my current air atomizing aeroponic sytems chamber into hp aero chamber. it has dimensions of 4feet x 4feet x15inches.
it will be powered by 8-24 of the nozzles i just spoke of, that number is still pending as im still unfamiliar with hp aero at this point

i will be construcing a 64 site chamber which is 4'x4'x18inches. it will be powered by my two delavan nozzles

here they are, when you first turn them on your going to notice they have a really shitty spray patten, each one is unique!
people around these parts say there the only nozzle thats tried and true for the really hairy roots. if hp aero works out for me im going to build a few different chambers and try 20 different types of misting nozzles and test them all out.
keep in touch man ill be around here for good. cant wait til i get this down to a science

I have 8 of the Biocontrols black impingement nozzles, and out of 8 half are actually decent.

I just finished my custom nozzle assemblies this morning. I recommend these. They have an 80*
conical spray pattern and the first batch I got had built in filters in the nozzle. (Should help avoid clogs)

07 80F Tefen RED 80* Non-Drip Conical Spray Nozzles - Catalog# 22211078006

I'm running them @ 80PSI with an Aquatec 6800 (very quiet!!) booster pump with an in-line 80PSI
pressure switch (Aquatec PSW-280) and accumulator/solenoid setup. (2gal accum/6:18 fill time to 80PSI)

I've tested every nozzle I've gotten from them, without any issues like the Biocontrol nozzles.

http://www.freshwatersystems.com/p-2970-male-connector-nptf-polypro-14-x-18-nptf.aspx
(I use these 1/4JGx1/8NPT to screw into the ends of the T's with the Red Tefen nozzles in the top 1/8NPT section)

This allows me to easily remove nozzle assemblies for cleaning/replacement as well as allowing the assembly
to rotate on the PEX tubing line to allow me to adjust the angle of the nozzle for better coverage of the root zone.


Hope that helps!

I have the bios, the red tefen and some SS impingement ones...who will be the winner? maybe a combination of the two, or three? I haven't had a chance to test them yet, cant wait to see the results.

Here is some nozzle porn I made for you guys

Teffen nozzles.. best nozzle we have used. 80-100 PSI.

Those roots look pretty nice indrhrvest!

sweet someone doing work for me

a solenoid per nozzle eh? im going to try and use 2 solenoids in a 2'x4'x15" chamber, not sure on the number of nozzles yet.

it does help. youve just helped me get my per nozzle cost down to around 8 bucks. never noticed those 1/8 inch tees before $1.66 aint bad

haha well it might be a while till I'm able to test them, living in an apartment with a roommate, having no garage or balcony makes it a difficult environment to test HP stuff

I have a total of 4 solenoids, was thinking of only using 4 nozzles for my chamber...one solenoid per nozzle is probably overkill...I could just use one solenoid for all 4 nozzles and do just fine...I dunno, I guess I just like throwing money at my HP system

whats your chamber size and what logic did you use to come to the conclution that you wanted to use 4 nozzles for that space.

im sort of puzzled on how many i should put in my box im thinking 8 or 12 but this hp aero is so confusing to me, i will have 32 plants. i will have to look at my system when i get to there and scheme.

i like how in air atomizing you can just cut two holes in the side of your box in adjacent corners insert your nozzles and your done. two solenids per nozzle no dripping.

I agree, air-atomization is just great. If you have the right air assisted nozzle you can adjust soo much, and find the perfect setting of air and water. One day I plan on going air-assisted, but for know I forst have to complete my HP rig.

So about the chamber size...I used this diagram I found on RIU somewhere...I believe. I like the logic behind the placement of the nozzles. (I cant remember if it was Atomizer who posted this...or someone else...dunno)


So this would be my base design 9 sites 3x3, I would build on from this. If for example this wasn't enough coverage, I could easily add additional nozzles. I really like the idea of placing the nozzles on the side of the chamber, but also the idea of placing them on the bottom and having them shoot upwards is also appealing to me (like indrhrvest's setup). Maybe a combination of the both from the side and from below would work nicely. I'm least attracted to place them on the top having them shoot down, as I would like to avoid the radiant heat getting to the tubing...and for some reason it just makes more sense (at least to me) to shoot the roots with mist from the side or from below...

So yeah that's basically it. 9 sites 3x3 start with 4 nozzles and go from there. I have about 10 bios, 10 red tefen and a few SS impingement ones so I have many options. Depending on the coverage of each of these three nozzle types and their spray angels and throwing distance (@100PSI) I will make a decision about placement and quantity.

Let me know what you guys think

Regarding the chamber size..I have no idea. Once I test each of these nozzles I will try to figure out a size, but i'm aiming for a size that can comfortably hold 9 sites, without the plants being too crowded and that every root mass has enough space around it to allow the mist to freely float in all directions. Also I would like a deep chamber so no matter how large the roots get, that they never touch the bottom, so I would probably go up to 1 meter depth max...probably a bit less. A ballpark figure maybe 120cm x 120cm x 90cm...

interesting my plan is the opposite as yours, i will be using strictly bios from the top.
however if i were to use nozzles with a long throw, and a narrow angle i would do exactly as in your picture.
it just doesnt make sense for me though as the bios throw the mist out sideways,
i feel if i mount them on the top i will be able to lay the mist down gently on all the roots from the top down.

See that's the kind of stuff I need to figure out...my current plan might not fit it with the way the nozzles perform. Its just an idea for now. I guess if the bios mist goes practically sideways than it only makes sense to place them on the top shooting down. But I use a 600 watt HPS bulb and I'm worried the tubing would heat up the nutrients inside a bit too much if they are sitting right under the light...

Boy I've been skipping finding/following these great posts in all theses great catagories in prep for a set up and I was thinking exactly that spray down it even fits the natural shape of a root system filling the void between plants..great stuff I can't wait

atomizer says most air atomizing nozzles will work its more getting your conditions dialed that matters

i think you needent be so worried about the heat, theres only going to be water in the tube for around a second until the solenoid closes, not really enough to be worried about. if it bothers you you could wrap them in mylar or mylar bubblewrap.

now get on it so i can see some results

the great treefarmer fired his bio nozzles downward check his results
