Aeroponics grows plants in a mist environment. Unlike soil gardening — and unlike systems where roots sit in a growing medium — the roots hang suspended in air and are sprayed with water, or with water and a nutrient solution.
Garden Pool developed this particular 5-gallon bucket configuration as a compact and inexpensive way to grow food using a food-grade bucket. The unit runs on less than two gallons of water, which makes it far easier to move around than the larger 30-gallon tote aeroponics model Garden Pool also built.
It is a simple, forgiving system for growing and cloning vegetables and herbs. Cuttings from most non-woody-stemmed plants root well in it, and you can also grow plants through to harvest in the same bucket.
The basics
How does aeroponics work?
Plants sit in net pots in the lid, supported above the reservoir, with their roots hanging down inside the bucket.
A submerged pump pushes water — or nutrient solution — up a short riser to a spray head, which mists the enclosed root chamber on a timed cycle.
That is the difference from soil gardening, where roots grow through a medium, and from systems like deep water culture, where roots stay continuously submerged.
Read the full Garden Pool aquaponics guide for how these approaches relate to each other.

How to grow with aeroponics
There is no big secret: growing with aeroponics is another form of hydroponics. Use a hydroponic nutrient solution and follow the directions on the label.
Plan to drain the reservoir and refresh the nutrient solution every couple of weeks, or as conditions require.
Original section
Using aeroponics to propagate plants from cuttings
Aeroponic propagation gives cuttings a moist, oxygen-rich root environment without soil, and it is cleaner than rooting in soil.
For cloning you do not need to add nutrients — plain water is enough, and it does not need to be flushed as long as water quality stays clean. The original 2013 instruction read: "We just add tap water, let it run for an hour to let the chlorine evaporate, and then start cloning."
Parts
Materials

The original Garden Pool build used seven 3-inch net pots. Size and quantity can vary depending on what you plan to grow.
The original page ended with a "Click Here to Get the Parts" link to the old Garden Pool store. That store no longer exists, so no purchase link is shown here. If Garden Pool publishes a current parts destination, it will be linked from this page.
Workshop
Tools
- Saw suitable for cutting the poly riser
- Marker
- Hole saw sized appropriately for the net pots you choose
- Drill
- Safety glasses
The original guidance noted that a 2 7/8-inch or 2 3/4-inch hole saw worked with the 3-inch net pots used in this project. Verify the hole size against your own net pots before you drill.
Before you build
Safety first
This safety section is a modern addition to the restored page. It was not part of the original 2013 text.
- Wear eye protection when drilling.
- Secure the bucket lid before cutting so it cannot spin.
- Keep electrical connections protected from water.
- Use pumps, timers and cords rated for wet environments.
- Use a GFCI-protected outlet where appropriate.
- Create a drip loop in every cord so water runs off before it reaches an outlet.
- Unplug equipment before reaching into or servicing the reservoir.
- Use a food-grade bucket if you are growing edible plants.
- Follow the manufacturer's instructions for all pumps, timers and electrical equipment.

Step by step
How to build the 5-gallon bucket aeroponics system
The original illustrated instructions, laid out as numbered steps. The photographs and diagrams are the original Garden Pool images from 2013.
01
Plan the net pot layout
Decide what size and how many net pots you want to use. The original Garden Pool build used seven 3-inch net pots.
Space the pots evenly across the lid, keeping enough material around the outer edge and between the openings so the lid stays rigid.

Mark and cut the lid
Mark each opening, then cut carefully with the drill and hole saw. The net pots should sit snugly in the lid without falling through.
The original guidance noted that a 2 7/8-inch or 2 3/4-inch hole saw worked with the particular 3-inch net pots used in the project. Always test the fit against your own net pots before drilling all the holes.

Assemble the pump and sprayer
Screw the threaded poly cut-off riser onto the hydroponic pump, cut the riser to the height you want, and add the 360-degree threaded sprinkler head.
Set the pump assembly in the bottom of the bucket. The original instructions recommended a pump with suction cups and a pre-filter.

Install the pump cord
The original 2013 build ran the pump plug up through one of the net pot holes and into the timer.
Route the cord through an opening that keeps it clear of the spray and out of standing water, and leave a drip loop below the outlet. Do not force a cord through a tight opening or damage its insulation to copy the historical photograph.
05
Add water
The original system ran with roughly two gallons of water in the bucket — less than half full.
Whatever level you use, the pump must stay submerged to the depth its manufacturer requires.
06
Install plants or cuttings
Insert the net pots with their foam or neoprene supports.
For propagation, set cuttings so the stem base and developing root zone sit in the spray path without being battered directly by the sprayer.
07
Set the timer
The original 2013 Garden Pool configuration used a 30-minute-on / 30-minute-off cycle.
That is what this build used — not a universal rule. Actual misting intervals vary with plant type, root development, temperature, humidity, nozzle output and system design.
Applications
What can you use this system for?
- Propagating plant cuttings
- Learning the basics of aeroponics hands-on
- Growing herbs and smaller plants
- Classroom demonstrations
- STEM and agriculture education
- Experimenting with root-zone misting and hydroponic growing
A five-gallon bucket is a small reservoir. It suits smaller, shallow-rooted plants — it is not the right system for every crop.
Classroom use
For teachers and educators
This compact build is a useful demonstration piece for plant propagation, soilless agriculture, root structure and function, water delivery, hydroponics and aeroponics, engineering and system design, and controlled-environment agriculture.

Questions
5-Gallon Bucket Aeroponics FAQ
- What is aeroponics?
- Aeroponics grows plants with their roots suspended in air inside an enclosed chamber and periodically sprayed or misted with water, or with water plus a nutrient solution, instead of being planted in soil or a growing medium.
- Can you build an aeroponics system with a 5-gallon bucket?
- Yes. This Garden Pool project is a low-pressure aeroponic system built from a food-grade 5-gallon bucket, a submersible pump, a short riser, a 360-degree spray head, a timer and net pots set into the lid.
- How much water does this system use?
- The original Garden Pool build operated with less than two gallons of water in the bucket. Ongoing use depends on evaporation, plant uptake, how often you change the solution and how well the system is sealed.
- What size pump did the original Garden Pool system use?
- The original materials list specified an approximately 317 GPH submersible hydroponic pump, or an equivalent, with a 1/2-inch threaded connection. Pumps with suction cups and a pre-filter were recommended.
- What size net pots were used?
- The original build used seven 3-inch net pots with foam lids. Size and quantity can change depending on what you intend to grow.
- Can this system be used for plant cloning?
- Yes — propagating cuttings was one of the main purposes of the original design. Aeroponic propagation gives cuttings a moist, oxygen-rich root environment without soil. Non-woody-stemmed plants are the usual candidates.
- Can vegetables be grown in this system?
- The original article described growing herbs and vegetables in the system as well as cloning. A five-gallon bucket suits smaller, shallow-rooted plants; it is not suitable for every crop.
- How often should the pump run?
- The original 2013 Garden Pool configuration ran 30 minutes on and 30 minutes off with an appliance timer. Treat that as the setting used in this specific build, not as a general aeroponics standard — intervals vary by crop, root stage, climate and nozzle output.
- Do I need hydroponic nutrients?
- For growing plants to harvest, the original instructions said to use a hydroponic nutrient solution and follow the manufacturer's label, draining and refreshing the solution as needed. For cloning cuttings, the original instructions used plain water with no added nutrients.
- Can this be used in a classroom?
- It is a compact, low-cost demonstration system, which is one reason educators have referenced this tutorial for years. Classroom use should follow your institution's electrical and safety requirements.
