I have no problem growing indeterminate tomatoes and potatoes in aeroponics, its no problem to support the plants even when the roots are suspended in air. With hydroponics you are generally forced to use a recirculating system due the the amount of water that has to be delivered per irrigation. With aeroponics you can choose to recirculate or run to waste. The benefits of running to waste are many, the elemental content and cleanliness of the nutrient doesnt change, it always optimum. Its also less work because you dont need to do daily EC/PH checks or adjustments. If a root chamber develops an issue, pythium for example, it will be confined to that chamber. If you recirculate the nutrient, the issue will spread throughout the entire system requiring you to clean and sanitize not only every root chamber but also the pumps, every inch of tubing, reservoir etc.
That's really great info, thanks for sharing!

No worries. Imho, there are only 2 types of aeroponics, HPA and AA. LPA is closer to hydro than aero.
While all those pro's for Aerponics maybe fact.. the problem arises is when you have a system that is dependant on power.. and if the power goes down.. those roots will dry EXTREMELY fast and your plant will die. With hydro.. you can run a pump free/electricity free Kratky hydro set up.
Yes, that’s completely true. Any system that is power dependant is at great risk of failure if there is a loss of power for a significant amount of time. It’s always advised, and essential really for commercial growers, to have a backup generator.
There are ways to mitigate the risk of power outages, you can design high pressure aero systems that are completely off grid. th-cam.com/video/8pkp6SG0NvE/w-d-xo.html
Good vídeo, good information. Thanks and respective LIKE
In a self contained low pressure aeroponics system (plants and nutrients contained in the same reservoir), if there is a power failure, so long as there is water in the reservoir, the plants will continue to take in water through the submerged water roots and take in oxygen through the air roots that aren't submerged. It works like a Kratky system and can be maintained easily if there is a power failure. Also, while aeroponics does favor small leafy plants, it's not a problem at all to support larger fruiting plants if a container and media that is appropriate for the size of the plant is used. Anything you can grow in other types of hydroponics (dwc, ebb and flow, NFT) will grow just as well or better in a low pressure aeroponics system. High pressure aeroponics are much more touchy when it comes to power failures, however. I've found low pressure aeroponics systems to be the most forgiving type of hydroponics so long as the roots aren't fully submerged. Even in a DWC system, if your roots are fully submerged and you have a power or air pump failure the plants can start going downhill fast due to a lack of oxygen. I've not found that to be the case in LPA.
Amazing insight! Having the failsafe of a low pressure aeroponics system that defaults to a pseudo Kratky system in the event of a power failure is really useful.
Power failure would have no effect on any of my hpa setups, the power for the 12v timers and solenoids can be supplied indefinitely from a battery and solar panel. I can pressurize 40L of nutrient to 140psi without any electrical power which will run a hpa system for days to weeks depending on the crop. The loss of light due to power failure would be more of an issue, which would apply to any method that is reliant on mains powered lighting.
I have 2 questions, what would you recommend as the best generator that can be used for aeroponic systems, like what would be your go to generator for good performance. And question 2, what would you say can be the longest time a plant in an aeroponic tower can go for without water before the plant starts to dry up if the power goes out.
I liked and subscribed btw hehehehhee, awesome content brother.
Glad you are enjoying the content! Thanks for the like and sub :)
So regarding a generator it would totally depend on your setup. Simply put, calculate the total wattage of the appliances in your setup then select a generator with a slightly higher capacity than your systems’ demands to ensure a reliable power supply.
As for how long the plants will live without water, again there is no one answer fits all it depends on the type of plants, temperature, size of roots etc. In any case if the water stops running indefinitely your plants will dry out and die. However @PrisonerGlass left a great comment on this video about how to avoid the loss of crop in the event of power failure in low pressure hydroponic systems:
"In a self contained low pressure aeroponics system (plants and nutrients contained in the same reservoir), if there is a power failure, so long as there is water in the reservoir, the plants will continue to take in water through the submerged water roots and take in oxygen through the air roots that aren't submerged.

I am confused as one of your downsides notes that aeroponics has less support for bigger plants, but could you not simply use a dwc setup and transform it into an aeroponics setup? For example, thick net pots and misters that will miss the roots that come out?
Yes this is a great solution regarding support. This is not to say don’t try it or engineer a solution, simply that it might present more challenges or that there might be a system that is better optimised.
Is the use of larger quantities of fertilizers in hydroponics than in regular agriculture, or vice versa?
Generally speaking the fertiliser or nutrients used in hydroponics are used more efficiently because nutrients can be more precisely controlled and recycled in a hydroponic system. So while plants always require a specific amount of nutrition regardless of where they are planted the hope with hydroponics is that less of the nutrients are wasted or lost and therefore less will be required overall.
Which system you think would be better for… ya know 🤔
I get you. They both have their pros and cons depending on where you are growing, budget, etc. check the article linked in the description for more information.
It's said that earoponics have a lower disease risk and it barely requires spraying..... I'd rather go for that than spending less and then later I get to spend more on pesticides.
Well said!
Thats not right i worked in both aeroponics like towergarden by juice plus can plant leaves herbs an crops with the support cage and thats all in one tower ,hydro can only plant one in a system which needs different readings of ec ph tds for different crops .
The tower garden is hydroponic, not aeroponic. The amount of water delivered in a single 3 minute irrigation cycle would be enough to run a genuine aeroponic tower for a whole day :)
Why not both
The perfect solution
I think the leafs are more important and lighting , sound , and humidity temperature more important than root or soil
