See how Aero-Gro feeds roots without soil.
Roots don’t need dirt. They need oxygen.
Cycle ON: solution leaves the reservoir, flows through the delivery tube, and exits the nozzle as a fine nutrient mist around the roots.
Cycle OFF: the spray pauses while unused solution returns to the reservoir, helping the root zone stay oxygen-rich and ready for the next cycle.
This is the core advantage: roots receive moisture and nutrients without being buried in dense soil.
What makes aeroponics better?
Because the fastest, cleanest way to feed a plant is to suspend its roots in open air and mist them with nutrients on demand — a method NASA flew to a space station, then handed back to growers on Earth.
How it works
A plant, an air gap, and a fine mist
In an aeroponic system there is no soil and no standing pool of water. Plants sit in net cups with their roots hanging freely inside an enclosed chamber. On a timed cycle, nozzles release a fine nutrient mist that coats the roots, then drains back to a sealed reservoir to be used again. Between mistings, the roots simply breathe.
That air gap is the whole point. It is the difference between a root system that is fed and one that is also fully oxygenated — and oxygen at the root zone is what drives the growth.
The breakthrough is oxygen
Why air beats both soil and water
In soil
Roots scavenge oxygen from the tiny air pockets between particles. Pack the soil down or overwater it, and those pockets flood — the roots effectively drown. Nutrients are locked to the soil and released unevenly.
In water (hydroponics)
Roots sit in nutrient solution, so feeding is steady — but oxygen is capped by how little gas dissolves in water. Growers run air pumps just to keep roots from suffocating.
In air (aeroponics)
Roots hang in open air and receive 100% of the available oxygen, while mist delivers nutrients exactly when needed. More oxygen at the root zone means faster uptake, faster growth, and bigger, healthier root systems.
A mist roots can actually absorb
Droplet size is the whole game. NASA's research points to roughly 5–50 microns, and true systems mist in the 20–50 micron range — fine enough to be taken up right at the root surface instead of beading off and dripping away.
Energy spent on growth, not foraging
In soil, a plant burns energy pushing roots outward to hunt for water and nutrients. In aeroponics the nutrients come to the roots — so that energy goes upward, into the leaves and fruit you’re actually growing.
NASA proved it
Tested in orbit. Refined for your kitchen.
In 1997, NASA teamed with AgriHouse and BioServe Space Technologies to fly an aeroponic experiment to the Mir space station. The grower behind it, Richard Stoner II, had been patenting aeroponic methods since the 1980s. NASA’s interest was practical: in space, every ounce of water and weight counts, and aeroponics grows food with the least of both — no soil, almost no water, and clean roots free of pests.
What NASA found has held up on the ground ever since. The popular countertop gardens that followed grew directly out of this research — the same lineage behind the systems we build at Aero-Gro.

The headline number
Water to grow the same crop
Side by side
| Soil | Hydroponics | Aeroponics | |
|---|---|---|---|
| Oxygen at the roots | Limited by soil air pockets | Limited by dissolved oxygen | 100% of available oxygen |
| Water use | Baseline | Much less, recycled | Up to 95–98% less |
| Nutrient delivery | Soil-bound, uneven | Submerged solution | Targeted mist, on demand |
| Growth speed | Baseline | Faster | Fastest of the three |
| Pests & disease | Soil-borne risk | Water-borne risk | Sterile root zone, greatly reduced |
| Transplant shock | Common | Possible | Clean roots move easily into any media |
What it means for your grow
Less water, less waste
A sealed, recirculating mist uses a fraction of what soil or hydroponics need.
Faster to harvest
More oxygen drives quicker growth and more crop cycles in the same year.
Cleaner food
No soil and a sterile root zone mean far less disease — and no pesticides.
Stronger roots
Open-air roots develop dense, healthy structures with no transplant shock.
Grow anywhere
No dirt, no garden bed. A countertop, a classroom, or a basement all work.
Year-round
Plant and harvest on your schedule, indoors, in any season.
Common questions
Before you start
What is aeroponics, and how does it differ from hydroponics?
Aeroponics grows plants with their roots suspended in open air and fed by a fine nutrient mist on a timed cycle — no soil and no standing water. Hydroponics also skips soil, but it sits the roots in a pool of nutrient solution. The difference is oxygen: aeroponic roots are surrounded by air, so they get far more of it, which drives faster growth and even lower water use than hydroponics.
How do Aero-Gro systems achieve faster plant growth than soil methods?
In soil, roots burn energy hunting for water and nutrients locked between particles. Aero-Gro delivers an oxygen-rich mist straight to the root surface on demand, so the plant absorbs exactly what it needs and puts its energy into leaves and fruit instead of foraging. More oxygen plus targeted feeding adds up to noticeably faster growth and more harvests per year.
What types of plants thrive in high-pressure aeroponics systems?
Leafy greens and herbs — lettuce, basil, kale, spinach — are the fastest and most forgiving, so they are a great place to start. Fruiting crops like tomatoes, peppers, and strawberries do very well too. Just about anything that is not a large root vegetable is a strong candidate.
How much water and nutrient solution do I save with Aero-Gro compared to traditional gardening?
Because the mist recirculates in a sealed loop, almost nothing is wasted. NASA measured up to 98% less water than traditional growing, along with roughly 60% less fertilizer. A system can run for days on a few gallons that would barely water a garden bed once.
What are the key steps to set up an Aero-Gro system at home?
Most growers are up and running the same day: assemble the bucket and net cup, fill the reservoir and mix in your nutrients, set the misting timer, and place your seedlings in the basket. From there it is largely hands-off — the timer cycles the mist and the solution recirculates on its own. Every kit ships with step-by-step instructions.
How do I maintain optimal nutrient levels with Aero-Gro’s system?
Keep an eye on three things: the reservoir water level, the nutrient concentration, and pH. Top up the solution as your plants drink it, check pH so nutrients stay available to the roots, and refresh the mix periodically. A 5-in-1 meter turns this into a two-minute routine, and we walk you through the target ranges for what you are growing.
What kind of support does Aero-Gro offer for DIY kit users?
Every kit comes with clear setup guides, and you can reach us directly whenever you have a question — we build these by hand, so you are talking to the people who actually make them. We are glad to help with setup, nutrients, pH, and troubleshooting so your first grow goes smoothly.
How can I troubleshoot common issues with aeroponics systems?
Most issues trace back to the mist, the solution, or the pump. If plants look stressed, check that the nozzles are not clogged and the timer is firing, confirm the reservoir has not run low, and verify pH and nutrient strength are in range. Clean the nozzles periodically and keep the reservoir sealed from light to prevent algae — and if you are stuck, reach out and we will help you diagnose it.
Are Aero-Gro systems suitable for beginners, or do I need prior experience?
No experience needed. The system handles the hard part — a timer runs the mist and the solution recirculates automatically — so your job is simply checking water, nutrients, and pH. If you can keep a houseplant alive, you can run an Aero-Gro system, and we are here to help if you get stuck.
What’s unique about Aero-Gro’s local, hand-built approach?
Every Aero-Gro system is hand-built locally, not mass-produced overseas. That means tighter quality control, real people behind the product, and support from the folks who actually assembled your kit. You get NASA-proven aeroponic technology made with genuine craftsmanship by people who care that it works.
