Advantages and Disadvantages Of High-Pressure Aeroponics!
This Video is from the Youtube channel: “Aero-Gro”.Β
Video begins at the 6:00 minute mark.
Here we’ll take a look at an actual high-pressure system. I’ll talk about some of the advantages and disadvantages of both high-pressure and low-pressure systems, so you can make the best choice for your own systems.

Hi Andrew,
Great content. What is the best way to contact you for questions? I tried several times through your website and have not received any responses back yet.
Bob
I apologize for the difficulty getting through via the website. You can always give me a call or text me at: 610.657.8800, or you can email me at: aerogro2021@gmail.com. Thanks so much for watching! Looking forward to helping anyway I can.
High pressure aeroponics (HPA) uses a water pump andd generallly an accuml;taor. Air Atomised aeroponics (AAA) uses an air compressor π I wouldnt get away with your compressor`s noise level, i`d get lynched hehe. I recorded the noise level of my 3.3cfm homebrew at 3am when you could literally hear a pin drop, https://youtu.be/iVZAqEgPAEE
The noise in the background is an aquarium in the same room. I have a commercially made Jun-Aiir and a Bambi (both 30db) running other systems.
MyI run my siphon fed nozzles at 25psi, 1 second of mist (26gal container): https://youtu.be/LYv_hw1Xx8c Two nozzles will handle upto 100 gallon root chamber. I wouldnt use a 5 gallon bucket for AA as it doesnt provide nearly enough space for the mist and the roots. Your going to need a bigger root chamber π
Yes – this is what I would call a “happy medium” between true “high-pressure” and “low pressure aeroponics. I agree about the noise level, which is why I will be demonstrating how to convert a refrigerator compressor to silently deliver the required air.
I have to disagree with the statement about the size of the five gallon bucket. I have had tremendous success using 5-gallon buckets for both the root chamber as well as the nutrient tank.

My home brew uses 2 beefy 3/4hp danfoss compressors.. The displacement of each compressor is 2.1cfm, the actual output is 1.65cfm. A typical fridge compressor will have a displacement of 0.6cfm, which will provide an output of around 0.47cfm. A 25L tank 0-120psi will take around 15 minutes 20 seconds to fill. Topping up from 85psi to 120psi will take around 4 minutes 28 seconds. Based on the commercial compressors which use similar tech, you shouldnt exceed a 50% duty cycle or allow the case temperature to exceed 100 deg C. The oil will turn acidic and eat the copper enameled motor windings π If you go this route, i`d recommend replacing the oil in the compressor with Shell Tellus 68 or an equivalent non foaming hydraulic oil. The amount to use will be listed in the compressors spec sheet normally available on the manufacturers website. You`ll find the tricky part is figuring out when to add oil as there`s no sight glass to help you out. I fitted an hours run counter and over a 6 month period of testing, figured out how much to add based on running time. I use a 0.01Β΅m coalescing oil filter on the output and change the oil in the compressors annually. Be sure to use a good quality pressure safety device (or two) with these compressors as they can easily exceed 800 psi π
If you get the chance, try 2 nozzles staggered on the opposing short sides of a 50 gallon root chamber running 45psi and a 0.5 /60 second cycle. As the plants grow bigger increase the on time by 0.1 second. Based on my homebrew compressor i`d get about 13 hours 16 minutes system run time before the compressors fired up to refill the tank, ymmv π
Wow. That is seriously impressive how you just did all that math! That just inspired me to do some testing. Thanks!!

I`ve had a lot of practice, I know the real flow rate of all my systems which is useful fro knowing how much i am giving over a period of time, per misting per hour day etc. I know how long an accumulator will run a system for. I can calculate how much nutrient i need to add to an accumulator to get it to run for a certain amount of time, an extra hour, day etc so the tank being almost empty will coincide with a change in nutrient formulation. If you know what is in the tank (based on the tanks volume and pressure) and how much a system will use based on measured nozzle flowrate and timing cycle ..its easy to figure. I create xls worksheets for everything which makes life easier. I can see at a glance what a change in timing cycle will do to the nutrient quantity delivered to the chamber per misting, per hour or day, and the accumulator run time based on its current pressure. I find it hard to understand why folks dont measure what can be measured π
System looks great! Well the end product looks great,can you supply a rocket scientist to install n programme please? Will take one.
Yeah, I know… the high-pressure aero can be intimidating. Stay tuned though, because I’ve discovered new ways of doing this that are much simpler and more straight-forward. I’ll be covering that. Thanks!!
Atmospheric nutrification
Oh man… that’s good…
How long do you run the fan?
The systems I design have the fan running the entire time that the spray is not actively spraying. The fan literally shuts off during the spray cycle, then immediately turns on again. This typically works out very well, as long as the fan is the correct size and running at the correct speed.
Is there any reason why you couldnβt use the guts from humidifier to deliver the nutrient solution and have basically the same aerosolize as you were achieving with your device?
That’s some really creative thinking!!! I like the ides in concept, but I thing the problem would be the “aerosolized” part of the equation. The nutrient solution needs to contain the actual nutrient salts when it reaches the plants’ roots. A dehumidifier is simply pulling moisture from the ambient air, then letting it drip down an evacuation hose. It’s not actually aerosolizing anything, and what it discharges is pretty close to pure water.
A sprayer, conversely, delivers both the water AND the nutrient solution because it never separates the two – it simply sprays it onto the roots.
But again – that was a way-cool idea!
You kink of lost me on this you are saying the nutrients in the solution would separate and not be a part mist is that correct ? I really appreciate your help with this and think your You Tube Show is GREAT please keep it up
So – think of it this way – if you were to add nutrients to a pot of water on the stove, then evaporate all of the water, the nutrients would be left on the bottom of the pan. Same thing with an evaporator. The evaporator just pulls water from the air by condensing it, but in so doing it leaves the nutrient salts behind, which is what the plants need. Hopefully I’m understanding what you’re asking, but let me know.
Thank you for getting back to me I appreciate it
