How to Make a Simple Aeroponics System

Aeroponics is growing plants in a mist environment. Unlike traditional aquaponics and hydroponics, the plants are suspended without grow medium such as hydroton. Here is the inside of the aeroponics system.

Aeroponics is a really simple and worry-free way to grow and clone veggies and herbs. Aeroponics is growing vegetation without soil, but the roots are suspended and sprayed with water and/or nutrient solution. It is a worry-free way to clone most non-woody stemmed plants from cuttings. You can also grow plants to harvest in the system as well.

The aeroponics system cloning our favorite tomatoes. Tomatoes take around one week to develop roots from cuttings. In two weeks they can be transplanted or continue to grow in the aeroponics system with nutrient solution.

Many folks have seen the aeroponics system we designed at the Garden Pool and we have decided to share our design. It is easy to both build and operate. The project takes about 30 minutes to build and only costs around $70 in materials. If you are cloning, it requires just tap water. If you are growing to harvest, then you can add hydroponic nutrient solution. We have our units sitting on our back patio and have cloned and grown mint, tomatoes, lettuce, and much more. The system we design can be built by anyone for a of comparable commercial units.

How to Grow with Aeroponics

There is no big secret, growing with aeroponics is another form of regular hydroponics. Purchase your favorite hydroponic solution from the hydro supply stores and follow the directions on the label. It is pretty simple to follow. You should be expected to drain the water and add more nutrient solution every couple of weeks as needed. Aeroponics and hydroponics uses more water and resources than aquaponics.

How to Clone with Aeroponics

Cloning with aeroponics is a better method than conventional soil root cuttings. It is quickly becoming the preferred method of cloning. With cloning from cutting with aeroponics you do not need to add any nutrients to your water. You do not have to flush your water as long as the water quality stays clean. It is a much more sterile way to clone than soil cuttings. We just add tap water, let it run for an hour to let the chlorine evaporate, and then start cloning. Here is a detailed video about cloning with aeroponics. The info about aeroponic cloning starts at 5:40 on the video.

  1. Decide what size net pots you wish to use. The pots should be spaced a few inches apart. We used six 3.75" net pots as we will use primarily to clone tomatoes. Use many smaller pots for smaller crops.

  2. Carefully cut your holes for your net pots. You can carefully use an exacto knife instead of the drill and hole saw. The net pots should fit snugly in to the holes and not fall through.

  3. Cut the 3'4" PVC as follows: (6) 4.5", (6) 6", (1) 8", (2) 3".

  4. Using the pvc glue and primer, connect the 4.5" PVC pieces to the PVC elbow connector and the 6" PVC pieces as shown. the 6" piece will serve as the riser.

  5. Using the PVC primer and glue, attach the 3/4" slip to 1/2" threaded PVC connector. Screw in the sprinkler heads as shown.

  6. Using the PVC Primer and glue, connect two 3/4" "T" PVC connectors and one 3/4" "cross" PVC connector as shown.

  7. Connect the two 3" PVC pieces to the 3/4" "T" with the threaded 1/2" top. Also connect the 8" section to the risers. Screw in the 1/2" barb to 1/2" threaded connector.

  8. Place the PVC sprinkler unit inside the tote. Connect the fountain pump to the PVC unit with the 1/2" flexi-tubing. Make sure there are no kinks in the tubing.

  9. Using the entire tube of silicone caulking, seal the lid on top of the aeroponics system. Make sure that the seal is airtight with no gaps of coverage. Let completely cure and dry before using. Install the bulkhead fitting at the desired location along the bottom of the unit. Attach the shut off valve with flexi-tubing as a drain valve.

  10. Insert the net pots with foam lids. We place our unit on a timed cycle of 30 minutes on and 30 minutes off. Fill with water to just below the sprinkler heads.

The pump and/or air tubing is placed in on of the net pot holes. Your fountain pump should be able to easily fit through the hole. Check before sealing the aeroponics lid.

A 1020 humidity dome helps young cuttings by keeping a more humid environment.
