Fogponic Garden (Hydroponics With Fog)




Introduction: Fogponic Garden (Hydroponics With Fog)

About: Trying to make the world a little better, about 14 projects at a time. Find me on Instagram as @that_severin, and as @tiefpunkt pretty much everywhere else online (twitter, github, ...)

A small fogponics garden for Basil, using an IKEA box, an ultrasonic fogger, and an aquarium air pump.


  • 1 IKEA SAMLA box, 11l, black + matching lid
  • 1 ultrasonic fogger (I got mine in a pet shop, they're often used in terrariums)
  • 1 Aquarium air pump, plus tube and air stone
  • Net buckets
  • A bag of hydroton, large enough to not fall through the net buckets
  • Plants (I used basil)

Additionally, you'll need a light source. You could just set this up on your balcony, or use a daylight lamp.

Step 1: Get Some Plant Cuttlings

I wanted to put some basil in my fogponics setup. I had a small basil plant on my balcony, so I cut off some stems, placed them in water, and waited a few weeks until they had grown enough roots to place them in the fogponics garden.

Make sure to cut the stems fairly low to the ground, so you have a lof of stem to work with. You'll need to exchange the water every days, and make sure to not have any leaves in the water. They should get enough light as well, but direct sunlight would probably not be such a good idea.

Step 2: Prepare the Box

Take the lid of your box, and make holes for the net cups. If you have a hole saw with the right diameter, that's probably the easiest ways. I did not, so I drew the circles with a pencil, and drilled lots of small holes on the inside, very close to the line. I then took a box cutter, cut out the inside of the circle, and trimmed the sides so the net cups would sit flush on the plastic, without falling through.

Then, make two holes in the box, right underneath to top rim of the box, one for the air hose, and another one for the cable to the fogger. Depending on your fogger, this hole has to be a bit bigger to fit the power connector of the fogger through it.

Step 3: Plants in Net Cups

When the hydroton comes fresh out of the bag, it's usually still quite dusty and dirty, so it's a good idea to wash it before using it.

Now take a net cup, put in a plant cutling so a bit of the roots come through the bottom, and fill the cup with hydroton to stabilize the plan. Repeat for the other cutlings.

Step 4: Setup Air Stone and Fogger in the Box

Place the fogger in the box, and push its plug and cable through the hole near the rim that we drilled earlier. Don't plugin it in the powersupply just yet.

Take some air tubing, push it from the outside into the box through the other whole, and connect it to the airstone. Cut the tubing to an appropriate length, and connect it to the airpump.

Now, fill your Samla box about half with water, and plug in the fogger. It should start to create a mysterious looking layer of fog on the water. Plug in the airpump, and the fog should disperse a bit more, and you can see air bubbles in the water

Step 5: Put in the Plants

Put your plants (in their net cups) in your fogponics box. If you don't fill all holes for net cups yet, make sure to close them off with foil. Now, it's just waiting until stuff starts to grow.

I put the fogger in my system on a timer, so it runs for 30min, and then stay off for 30min. Just didn't trust it to run all the time, and this seems to work fine. The airpump just runs all the time.

    For everybody that's asking, the fog allows the plant to breathe oxygen and the nutrients in the water at the same time, as the ultrasonic fogger makes the fog extremely small. This is from Wikipedia however it makes sense.

    I'm a little confused. Exactly what function does the fog generator perform in this system other than looking cool when you remove the lid of the reservoir. I have a fog generator in an "upcycled" concrete bird bath in my living room. It has LEDs to change the color of the fog, but other than esthetics it really does no seem to serve any function to me. However, my bonsai seems to like it when I place it under its humidity cover when I am away for an extended period of time.

    Great instructable and thanks for sharing it with us.

    OP, very well done. What are the advantages of fog over traditional sprinkler head or submerged roots with airstones?

    Interesting good post!
    I think I'd you took your cuttings and put them directly into the hanging baskets with the tip of the stem coming out the bottom a half inch or so they may root faster and better than in a jar. Pls try it out n let us know. Try 15 ml micro and 30 ml bloom by general hydroponics in a 5 gallon reservoir start with 0ppm water you may need a Reverse osmosis water filtration system.
    Again cool post thanks for sharing
