Search for "short interval timer". I always use the BN-Link timers, they work.
Two notes for those timers specifically:
They have a light sensor and can be programmed with different day/night cycles. I've never used it, but it could be an option for further experimentation.. or you gotta know to turn it off otherwise.
The intervals written on the dial aren't perfect, it's just a sticker. If you really want to be precise, grab a stop watch and dial your intervals in.
This is the one I've been using for the last year. My setup relies on a 12v power supply. 12 volt programmable timer
My cycle is 10 seconds on 5 minutes off. I used this 24V cycle timer connected directly to my 24v pump. I hope this helps.
I actually got them off Amazon, I’ll send a pic in a little bit. I started with the tefen nozzles from Amazon. But the ones I bought had to be run with 3/8th and I wanted them run at 1/4 so I bought REDTRON 10PCS Misting Nozzles,... https://www.amazon.com/dp/B093C7W1MJ?ref=ppx_pop_mob_ap_share These and they are fantastic, easy to change out but I haven’t needed to yet and way cheaper. Then I just used padded cable clamps to keep them in place which works nicely because they are tight enough so that when I move them they stay put. I got the clamps at Lowe’s or Home Depot. They were like 3 bucks a pair but worth it.
I use these adapters, with an additional stub of 1/4” tubing off of a tee. Sucks because the SS filters won’t fit, and you have to trim the poly ones to make it work. And it’s two fittings instead of one.
I’ve also found nozzle tees, but have never used them, and most seem to be made for 3/8” tubing
Nickel may be fine with nutrient solution, I have no experience with it though.

Have you tried using a liquid filled pressure gage to dampen the pulsation?
I use this one from Amazon and it works great:
PIC Gauge 301L-402F 4" Dial, 0/160 psi Range, 1/2" Male NPT Connection Size, Bottom Mount Glycerine Filled Pressure Gauge with a Stainless Steel Case and Internals, Stainless Steel Bezel, and Polycarbonate Lens https://www.amazon.com/dp/B00FBMSH34/ref=cm_sw_r_cp_api_glt_i_J0MDTKMEPHMC7KA0BN1T?_encoding=UTF8&psc=1
I’ve seen the 3/8” push fit tee with 1/8” threaded female port (for the 1/8” male nozzle) on Amazon. Link below. Not sure about 1/4” x 1/8”.
I use 1/4” push-fit x 1/8” female threaded adapters. Kind of a waste of fittings though because each spray head requires a tee, a short stub of pipe, then the 1/8” threaded adapter, and finally the nozzle.
If I had run 3/8” main lines instead of 1/4” I could have used one fitting per nozzle. These are sold by Pro Water Parts on Amazon nozzle tee.
If you go the threaded adapter route like me, 2 things:
Buy poly filter version of the Tefen nozzle, you can trim the filter to fit in a regular fitting with a utility knife. Not true with stainless (though stainless is reusable).
Nozzles will not thread all the way in to the fitting, and you can crack them by over-tightening. Use some Teflon tape and they will stick out a bit but won’t leak

I have four of these and they work great so far.
Is it one of those peltier/thermoelectric dehumidifiers? I find that those don't really work and less efficient than the standard compressor style. But the compressor dehumidifiers are much more expensive.
I use this one: https://www.amazon.com/dp/B08694X9QW/ref=cm_sw_r_cp_apa_fabt1_SR-UFbDXFYBV7?_encoding=UTF8&psc=1
It's cheap and there's a good deal on it now. It supposedly is capable of 30 pints a day. I use it in the 10*8 room that my tent is in. It works pretty well.
But it puts out a decent amount of heat.
I've used one of these before and was happy with it.
Just a simple soft seat relief valve set inside the nute tank; attached to high pressure side.
I like to run safety devices mechanically; for adjustable I would just add a circuit within the safety limits as an addition to the mechanical limits.
Lines, components and fittings are all around 150psi; so scoped max to 125psi for normal operations and 150psi for burst shutdown.
Agreed; 1/4 to 1/2 on dosing is fairly normal in aero; listen to plant (or measure run off EC compare to nute). RO water or base water under 70ppm. Always easier to add more nute in.
EC/PPM meter and PH meter are almost a must for starting; or be a plant whisperer. Cheapies on amazon for 20 bucks, saves a lot of nute burned plants when starting.
I've had good luck with these for veggies/fruits; probably better out there (pay attention to NPK ratios):

The regular Tefen nozzles off Amazon. I tapped threads into the quick-connect fittings and attached the nozzles directly. High pressure, but this is just for starting the plants before they go into bigger chambers. Tiny little accumulator tank: https://www.amazon.com/Pulsation-Dampener-Accumulator-aeroponics-pulsating/dp/B08K9GZ9NQ
Just search aeroponic mister on amazon, they're pretty cheap. As for a pump, something like this would probably work OK.
u/nzrampage33 Do you know if you can hook up a pressure tank such as the one found here to your aeroponics system? How hard or easy do you think adding a pressure tank to your aeroponics system would be?
Also, I forgot to ask - for the aeroponics system you bought from alibaba, did it come with an on/off timer or would I have to buy something like this for the alibaba aeroponics system:

Can anyone suggest a decent fogger for a reasonable price? I did a test with one of these in a smallish container, but it still didn't generate enough mist to be workable. I would love something that kicks out as much mist as my humidifier. Maybe I need to look for an old one of those to repurpose?
You really need a temp controller so you don't fry the seeds. Set it to 75 F and it will turn off when it reaches the temperature, and turn back on when it gets cold. What is your current heat source?
Amazon has a bunch of bundles with Temp Controller + 10" x 20" heating mat.
I use these. Just need to also buy the QC fittings which are also super cheap

It's very light weight it's meant for use in a semi climate controlled space. It won't hold heat, there made to do the opposite to help disperse the heat from the lights.
You can start searching from here n hopefully it can lead you to the proper plug.source

Depending on your setup you can go lower here's one that looks just like the one I have. I went with 800VA but if you have multiple pumps or a large setup you may want to consider that 1500

DmFit mesh screen filters are the tits. Shop around tho cause you will find some that are very expensive like on Amazon:

That is a low pressure aeroponic system.
You can find similar items from US distributors, marketed as cloners: https://smile.amazon.com/gp/product/B07RYR2F5G
Note that some of the cheaper "low pressure aeroponic" cloners are actually deep water culture cloners.
I have the hortipots above. It's a true low pressure system. It works great for growing new roots on a clone, but it's too small to properly support larger plants.
Yeah it's not even metal, just cosmetic, cheap chrome plating over plastic. It's flaking, I can pick it off. If I do use them again they will be mounted on the exterior.
This happened over a month ago. I'm not using them switched to a nickle plated brass. So far so good.
It's okay ask away. I can't answer your questions if you don't ask them lol. In the images of system, for test one, I only had one mister on the longer length of the bin. The new misting head, for test two, is on the short length. My hope is that this will create vortices and spread the mist over a larger volume of the bin.
Distance to roots is variable as those closer to mister will be a lesser distance. No solenoid. I only run on a timer for now.

Ever played around with o-rings or gaskets in this design?
I find salt buildup creeping out around the seams so added an o-ring. I even added o-rings around the bolts, though that's probably overkill.
Just bought some taulman3D nylon 230 and hoping to print my own o-rings 👌
I use two of These
I can't find the ones that also used a wick like his but when I made the comment I had found some so they are around. Probably just have a dumb name or something
I use these and they work great.
Gems Sensors A2015-C203 303 Stainless Steel General Purpose Solenoid Valve, 175 psig Pressure, 0.155 Cv, 3/32" Orifice, 12 VDC Voltage
This what I am using. <https://www.amazon.com/gp/product/B07QN63XF3/ref=ppx_yo_dt_b_asin_title_o06_s00?ie=UTF8&psc=1> (sorry, new to Reddit, don't know how to embed link)
It is 1.7MHz, not the 113KHz a lot of the small humidifiers use.
Bondic comes with in a "pen" that makes it trivial to place a drop exactly where you want. I only need a few drops to waterproof the wires. It comes with a little led curing light that takes under 10 seconds to cure.
Not sure if this is what you're looking for, but I put all my power running through smart power strips. They measure throughput and I divide by the amount of plants being grown to get per unit cost. My system is very small though, so it's easy and there aren't many concerns.

This really is just the connector on the Aquatec 8800 and its pressure switch. I found several different angles pictured here.
I’m using the Aquatec accumulator. I precharge it with air to 100 psi, while I have my Aquatec pump, pump it up to 120 psi. From the accumulator it goes to a Watts P60 pressure regulator that I have adjusted to 100 psi output. Then it goes to a pair of solenoids that open for 2.5 seconds and shut for 5 minutes. Each solenoid has a single blue Tefen nozzle.
That little accumulator will last for 1 hr 15 minutes before the Arduino that controls it all starts the pump back up to bring the pressure back up to 120 psi.

You could use a relay like this one:
Connect your 5v power supply Vcc(+) and Vee(-) to "DC+" and "DC-" on the relay. Connect one wire from your solenoid to the Vcc(+) wire on the 24v DC supply. Connect the other wire on your solenoid to the "NO" (it means the circuit is "normally open" no current flows ) on the relay. Connect the Vee (-) wire from the 24v DC supply to the "COM" on the relay. Connect a gpio signal pin from the rPi to the "IN" on the relay. When the "IN" pin is "high" (3.3v) the "NO" and "COM" are connected together and the solenoid allows water to flow. I'm not an expert so be skeptical and verify my advice :D
So far doesn't sound like anyone has given you good advice. Here's a link for the plugs I use for my solenoids. Cheap and reliable. Plug into an interval timer and your golden https://www.amazon.com/dp/B01HCRUGPW/ref=cm_sw_r_cp_apa_fabc_3fXUFbY8649EB?_encoding=UTF8&psc=1
A lot of people use a bigger tank around 8L but I found quite a small one that works with my compact set up, of course with a smaller tank your pump will be working more often. Can you post links here? I'm using a Shurflo 182-200

You are going to need basic understanding of programming and electrical wiring to do it with an arduino. It is not a plug and play solution, but it is a really good option.
Something like this might be better. An arduino will cost you more.
I used this valve with a built in short cycle timer. I used a tower system. I used five misters per tower that both drained back into a reservoir.

I've used same active ingredient as this in hydroguard, this is much more concentrated. Hydroguard is amazing, ive brought plants from full-blown root rot to beautiful shiny white roots. Ran a cloner for about 5months only cleaned the res and just added cuts to it with about 99% succes and zero rot running the hydroguard.

I hadn't thought of that. But I wish I had. I'm definitely going to need to cool the water in the reservoir somehow.

Wow already have take some really good ideas from you !thanks for the amazing share .. I’m working on a HPS aero system and I think I found the best size I’m looking for I looked into buying acrylic, plexi and all sorts of other materials your right cost is a factor so this is what I found I can pick them up for 100 a piece and I would buy 2 of them and use one as a lid flipping it on top of one another with cutting the lip / rim with a Dremel

Botanicare Tray 4 ft x 4 ft ID - White https://www.amazon.ca/dp/B002ONM1EO/ref=cm_sw_r_cp_api_i_vbcvFbAMB39R1
I’m going to use 2 of them flip 1 upside down on top of the other obviously customizing the size of the lip so it slides into the bottom
Having an arduino do this stuff for you would be pretty cool but imo it's a lot of complexity for something that is actually very simple. You can get your own PH/TDS/EC meter, check it once a day or every few days, and add water or fertilizer or both by yourself via dropper. It would make more sense to use intelligent automation/assistance if the system were much much bigger.
Recirculating pump is helpful, but if you get a good air stone and a good air pump with high flow the bubbles will aerate the water and churn it over and mix it very well and very quickly in such a small container.
I use one of these https://www.amazon.ca/Bluelab-BLU2300E-compteur-conductivit%C3%A9-temp%C3%A9rature/dp/B003PD2N8Q/ref=sr_1_3?dchild=1&keywords=bluelab+combo&qid=1599330449&sr=8-3 and they are pretty cool, but they are so expensive and the probes don't last nearly as long as I feel they should for how much they cost.
When I said the challenge is in feeding the plant I didn't mean the physical process, putting one liquid into another liquid is very easy, but knowing which liquid, and how much of it and why is as much of a science as it is an art form.
There are of course many guides on good starting mixes, if you are lucky this will suffice for a very long time, but once you get a single issue such as over fertilization, or root slimes, or algae or any of the other myriad of problems one can get in hydroponics you'll have your work cut out for you!
But it's an awesome hobby! As as a general rule, "an ounce of prevention is worth a pound of cure".
Keep in mind I haven't done my research, but the idea might be to measure ph/tds with an arduino and dispense from a nutrient/ph resovior accordingly. Also have an extra water pump just for circulating the water around the bottom. Thoughts? I'm curious to know how its done in the marketplace
I apologize, I should have looked more into your setup, I must admit I've always gone overkill for fittings and have only really used polypropylene barbed fittings for drip irrigation and your pump may very well be too forceful. If the lack of solenoid and pressure tank are appealing to you either using your pressure switch, or buying a reducing valve before you switch over to polypropylene fittings.
For the nozzle the droplet size primarily does not depend on the diameter of the outlet, but on the method of fading and splitting the flow. You don’t have to use a 45 micron nozzle to get "air roots", buy a quality 100 micron nozzle - it will give you drops from 5 to 10 microns.
You can start with this kit and then upgrade it to other nozzles if needed: https://www.amazon.com/Yotako-Misting-Nozzles-Slip-Lok-Outdoor/dp/B0746HKL47/ref=pd_day0_hl_86_3/131-4957759-6171218?_encoding=UTF8&pd_rd_i=B0746HKL47&pd_rd_r=51905ca2-a94a-11e9-af57-6d67ff94472b&pd_rd_w=PyC4V&pd_rd_wg=emqQU&pf_rd_p=ad07871c-e646-4161-82c7-5ed0d4c85b07&pf_rd_r=GWTYG4PRBFCKCAK6D4BC&psc=1&refRID=GWTYG4PRBFCKCAK6D4BC
I use a 5 micron filter bag that helps quite a bit. Sometimes nozzles clog, that's the nature of working with dissolved salts. Just make sure you monitor appropriately and the nozzles can be changed easily.
I don't have that much vertical space either...
What I did last time was cut a 1" hole to the bottom of root container, added a fitting for a short hose that ran into a condensate pump.
Which collected the run-off and every so often turned on and pumped it back into my main reservoir.
Thanks! Here is the link to the short cycle timer we purchased. Easy to set up and exactly what we were looking for.
As this is my first foray into plant growing, I just picked stuff essentially at random that looked right. :P
This is the ultrasonic fogger I got: https://www.amazon.com/gp/product/B00PAK245E/
For the first few weeks I only used water, but I switched recently to adding in a small bit of hydro nutrients: https://www.amazon.com/Blue-Gold-Hydroponics-Concentrate-Fertilizer/dp/B01LX3OXNW
The clay pellets suck, so I will advise strongly against them. I'm ordering some rockwool now, and hopefully I can get some more seeds going so I can try it all out.
From what I've researched, the sprayers they use in those systems aren't typically sold individually. Believe this is the closest you can find on its own.
http://www.amazon.com/General-Hydroponics-Vortex-Sprayer-Gardening/dp/B003L1NLZQ
Happy to help :) I just finished building my table and ordering all the parts for the actual setup and had came across people discussing the sprayers in that system and that was what people had linked. Pretty sure it's not exactly the same as used in the seemorebuds videos, but close. If you're attempting true high pressure aeroponics then you should use atomizing nozzles. You want water droplets between 5-50 microns.
