I use hypro`s and netafims and neither drip, the adv`s open at around 4 bar ~ 58psi. Throw the tefens into ye olde aero spares box ;)

You`re not ignorant, you`re just in the transition phase between what you imagined would happen (swirl / vortex) and what actually happened ;) Just to clarify, the flowrate capacity of a solenoid can run a bunch of nozzles but when precise control is the goal, one nozzle per solenoid (zero...

From a flowrate point of view it puts out less liquid than the ultrasonic but looks more due to the wider droplet size range. Its hard to judge the droplet sizes in a cloud of mist, what you may think are 50 micron could be 150 micron or more. To get an idea of size, try to find a piece of 325...

The comparison is a microfog / aerolife ultrasonic nozzle and a standard siphon fed AA nozzle. The air pressure on the last nozzle was 30psi with 6" of siphon height (as measured from the water level to the center of the nozzle). The difference between the two is the ultrasonic uses a resonator...

The first 3 vids are the ultrasonic AA nozzle, its not from china and it didnt cost $18 ;) No solenoid in the test, just a 3/8" airline hooked directly to the nozzle so there is a ramp in pressure at the start and finish but i let it run long enough to show the mist quality you can expect to get...

Had some free time today so i hooked up the nozzle to show what kind of mist you can expect for your $200-$300. I used 4" siphon height and air at 15psi, 20psi and 40psi respectively. I didnt bother with a timer or solenoid so you`ll have to imagine what a second of mist looks like ;) The...

Flow numbers only apply if you have full mist coverage (#1 priority) comprising 5-80 micron droplets. One hydraulic nozzle may fulfill the flow rate requirement but it wont provide full coverage on its own. Increasing the number of nozzles to provide the coverage increases the flowrate so you...

microfog nozzles work if you have a dripper system doing the lions share of the irrigation. Fwiw, you can get identical stainless steel ultrasonic nozzles from china for around $18 each ;) Aeroscience aerotrays (3x3, 4x4 and 5x5) use microfog nozzles + drippers to keep the plants upright. The...

If you are blessed with low growroom temps you`ll be ok. My view hasnt changed from what i posted: With AA and HPA, the chamber depth and root temperature are the most important. I came up with the fabric chambers for outdoor hpa where there`s no control over the root temp and chest freezers...

Heck of a parts list ;) With AA it can be reduced to just a few items, compressor, timer, solenoid(s) and nozzle(s). With 30" of height to work with under the bench, i would find a cheap clean chest freezer for the root chamber. Make sure it has a drain fitted on the front (screw type plug). An...

Anti drip nozzles are the next best thing, response wise. to using a solenoid on each nozzle. When it comes to running drain to waste, mist run on can equate to more than the actual misting. Anti drip nozzles open at a set pressure and close at a lower pressure. Non anti drips will allow the...

The relay is a solid state relay (ssr), the ones that come fitted to these timers as standard are just cheap and nasty mechanical relays..You need something that can reliably do 1500-2000 cycles a day every day for months ;) The reliability goes for the compressor cos theres no mist without...

I have a few compressors, this one is the smallest of the bunch. The nozzle(s) will need to be matched to the chamber size, if one size fitted all it would be a lot easier. Compressor CFM is irrelevant here because the nozzles run short mist pulses. How often the compressor runs depends on the...

Only when its running ;) AA nozzles dont consume much air so it wont run very often. Mine use less than 200w a day, about the same cost as running a 9w aquarium air pump for 24hrs ;)

The only thing you can say for sure is it has a flat fan pattern, beyond that your guess is as good as mine ;) I suspect its a pressure fed nozzle but for the price it may be worth a punt.

You may be looking at the wrong nozzles if they cost $27, generally they are over $100 ;)

air assisted or air atomized aeroponics. Its been around for well over a decade ;)

I dont think AA is the method for you then ;)

The toms variety is called minibel, they reckon to get a foot tall but i`ve grown them before and its not always the case. The barrels are repurposed water butts around 60 us gal each. PH 6.3 is about as high as i`d want to go but you`ll be ok at that ;)

I would check which iron (Fe) chelate masterblend uses, EDTA will struggle at ph 6.4-6.7, if its DTPA its not so bad. Dwarf toms are ideal for limited space, the only downside is the toms all arrive at once ;) I have 45 growing in an outdoor vertical hpa setup.
