nutrients won't fog, waste of time for pot, decent for other applications.
don't waste time on nebulizers/foggers.
Nutes wont fog? huh? lol. I have friend running the 1000psi version of this pump feeding some big vertical tube setups and i can assure you the nutes absolutely "fog" or fine mist if you will. Plants get a 400ppm mixture max and they are unbelievably healthy. sometimes he has to dial them back to 200ppm to slow them down.
Not if you maintain the nozzles weekly. keeping a spare set is crucial when dealing with the small orifice fittings.
You can go for it if you like, but dont say i didnt warn ya that those 10/24 threaded patio misting nozzles will be a nightmare
@cat I can turn neat neem oil into fog with 40psi of compressed air
I appreciate the recommendation but we have good luck with the .008 nozzles. The 1000psi pump they offer is great option i was hoping to hear from someone who has tried the 300. I'm hoping they are as reliable.
Sorry just seeing this. Im not fixated on the pressure. We just had good luck with the higher PSI systems in the past so it's what I know. The new system is a new design. I'm going to run horizontal tubes insieated of vertical so I'm nervous that I won't get adequate coverage of the fog with the lower pressure systems.
In an 8' octagon (4 levels) I was initially going to run 4 sprayers per level but I'm thinking 8 sprayers per level is probably a better idea. I'm my mind that will without a doubt equalize feeding per level.
Now with that many feed sites per level I might infact move to the .012 sprayers.
I don't see how it would be considered NFT. I'm not flooding the roots. Each plant will recieve a fine mist and draining will be done by tilting the closiuem. I would prefer to grow in horizontal tubes as there is plenty of volume left in the tubes when he roots grow downward but the cieling height might prevent me from doing so.
Also what is "AA"
Also what is "AA"
The nozzles wont have enough space in a tube, the droplets will hit the walls, coalesce and become liquid again. The nozzle mist pattern consists of a cone diameter and a throw distance, if the cone diameter is 12" a foot from the nozzle, it`ll be 4" at 4" and if its facing downwards the mist will simply coat the bottom of the tube, 50 micron droplets dont bounce especially if theres a film of water already on the surface AA is air atomising aero, it uses twin fluid nozzles, liquid and compressed air. The liquid can be anything from water to molten chocolate.
Here`s a single AA nozzle atomising neat neem oil in a 57gal "pop-up" fumigation chamber.
Water is much easier to atomise than neem, 2 seconds of mist in a150gal.

Where are you getting 50 microns from? My nozzles atomize at 8 microns. 8 nozzles evenly covering each layer of the octagon should be plenty of coverage. No doubt they will coat the walls of left on to long but by no means will they flood the tubes and not make it to each plant as you are suggesting. It's all about the timing.
As stated earlier. Vertical tubes would be ideal as gravity helps out a ton in draining. In the vertical setup I'm referring to it only takes one .008 nozzle to feed an entire column.

All nozzles, hydraulics and AA`s put out a range of droplet sizes. if the nozzle is decent quality you should be able to get a spec sheet showing the SMD,VMD values and droplet size distribution as a percentage of the whole at different pressures. A 0.2mm Amfog is a pretty standard brass/stainless hp patio misting nozzle. At 1000psi the VMD is 5 microns but the droplet size range covers 2-30 microns. At 250psi, the droplet size range shifts upwards to include larger droplets, the distribution of large and small droplets also changes. If the pressure isnt constant, the droplet size range wont be constant either, thats where solenoids have the edge over pumps, instant on.off versus a pressure rise/fall as the pump turns on and off.

i have heard in the world of hydro have not seen for myself but guys a running these in 50 ltr tubs like a dwc feeding roots

base nutes will but running like rhizo humic and fulvic acids and kelps clogs will be a nightmare unless u had a filter chamber be4 reaching the misters
Yes these specs were provided by aeromist. In the brief conversation I had with him regarding the 300psi Pump he claimed 8 micron from the .008 nozzles at 300 psi 10-40 sprayers given equal pressure.
I do like the solonoid idea but man that complicates things tremendously. I might end up running a lower PSI pump with a basic sprayer at each plant site. What do you think about that?
Yeah I have no doubt they can preform well given a space with decent volume. It's these damn 4" tubes that have me worried. I really don't want to run a Recirculating system..
1000psi solenoids would be expensive and not much use without some timing wizardry to sync the pump and solenoids to maintain pressure. I had to come up with something similar to control the rotary AA nozzle setup. You`ll find most salesmen arent too clued up on what they are selling, the figure he gave you will be the SMD (Sauter Mean Diameter) which is not related to the nozzles realworld droplet diameter 
The SMD value is the diameter of a ficticious droplet having the same volume to surface area ratio as the total volume of all the droplets to the total surface area of all the droplets. In a nutshell it tells you nothing useful about the actual droplet range delivered by the nozzle
The VMD ( Volume Median Diameter or Dv0.5 ) is much more useful. thats the value where 50% of the total droplets in the nozzle spray volume are larger and 50% are smaller, so if the VMD value is 30 microns at 1000psi, you`ll know that 50% of the droplets from the nozzle will be larger than 30um and the other 50% will be smaller than 30um.
Its upto you what kind of setup you want but imho using 300psi in 4" tubes will provide no benefit over low pressure sprinklers mounted at the top....unless you run them drain to waste
Here`s one of my AA nozzle datasheets, it`ll throw a giant plume of mist about 15ft, ideal for fogging a big greenhouse.

I see. The plan was actually to run them drain to waste.. I have no intentions on recycling the water.
