Parts/Shopping List:
  • 4” PVC (schedule 40) Pipe (Make O.D. measures 4.5”) in whatever height you want - I did 5’
    • You may see a thin walled option that is cheaper. GET THE THICK WALLED!
  • ½” schedule 40 PVC pipe in same height as 4”
  • ½” schedule 40 PVC coupler (to glue at one end so it will allow pipe to hang from the water distribution piece/part.
  • ½”” adapter for water pump line.
  • Water pump (make sure to get one that has a lift rating at tall as your tower or else the water wont pump to the top)
    • Amazon Link for a 2 Pack! Current price of ~$30 makes each pump $15 which not only is a great price but is ALWAYS good to have a spare in case your pump goes out. Once a pump stops working you only have a matter of a hour or so before plants start to suffer! Not to mention you can use the second pump to transfer nutrient water into your tower bucket(s) easily!
  • M4 screws (or similar) with washers and nuts (to attach pipe flange to bucket lid)
  • Phillips screws (stainless steel) number 6 x ½” (to attach pod holders, bucket flange to PVC pipe, aeroponic top to 4” PVC, and tube support part inside the 4” PVC pipe.)
  • Food safe bucket - I got a 5gal from Lowes
  • 100% Silicone - Clear (to make top, flange, and all pod holders water tight)
  • 2 ⅛” (54mm) Hole Saw
  • 5” (127mm)Hole Saw
    • Hole Saw Set from Harbor Freight works great! This set comes with both sizes needed for this build!
    • Heres also an Amazon Link if you don't have a Harbor Freight close!
  • 2” x 2 ¾” Net Cups
    • Amazon Link ) for 100 net cups that I purchased. It's good to have extra's on hand for future builds, replacements as they break, and starting new seeds when currently plants are nearing the end of their life so you can rotate plants in and out to shorten the seed to harvest timeframe!
Print List and Settings:
  • 1x Top Cap Bolt (printed with 20% infill)
  • 1x Top Cap (printed with 20% infill)
  • 1x Water Distributor (printed with 20% infill)
  • 1x Tube Support (printed with 20% infill)
  • 1x Pipe Flange (printed with 40-50% infill)
  • Net Cup Holders (printed with 100% infill) (However many you want)
  • Net Cup Cap (printed with 20% infill) (As needed when you don’t have plants in all net cup holders)
The STL print files are located on Printables.com on the Customizable Aeroponic/Hydroponic Tower project page.

Printing all the parts is really straight forward. No supports are needed on any of the parts. Print the net cup holders vertically with Brim to make sure proper adhesion to the build plate (see image below)
The rest of the settings will depend on what printer you have and what brand PETG you’re printing with.


Using your 5” (127 mm hole saw), drill a hole in the center of your bucket’s lid, as shown below.


Test fit your bucket flange in the hole.

Insert your 4” PVC pipe into the flange so the flange is higher on the PVC than the height of the bucket.


Now insert the PVC pipe into the bucket through the hole in the lid. With the PVC pipe at the bottom of the bucket, push the flange down the PVC pipe until it presses firming against the bucket’s lid. (This is a very important step to make sure the PVC pipe is at the bottom of the bucket because this is what provides the tower support from being wobbly.)


Remove the PVC pipe from the bucket and mark the flange location with a marker.



If the bucket lid you chose is white or another light color, it will be a really good idea to paint it black to help limit the amount of light coming into the water reservoir. When light comes into this bucket it can increase the changes of algae growth.


Once dry, put the lid back on the bucket and insert the PVC pipe with the flange to help keep it sturdy. Then figure out how you want to space out your net cup holders and dry fit them by securing them with the screws. (DO NOT OVERTIGHTEN SCREWS! Screws that are too tight will crack the net cup holders that took a long time to print!) Once everything looks the way you want, take your marker and trace the inside of each net cup holder.


Once all net cup holders are traced, remove all the net cup holders from the tower.


Using your 2 ⅛” (54mm) hole saw, start by drilling in the center of the circle with the drill bit.


Once drill bit has penetrated the PVC pipe, drill the hole saw at a roughly 45 degree angle. This will help ensure the net cups will move freely in and out of the tower.



Using a razor or box cutter, ream the excess from the hole to clean it up.



Flip the tower upside down and drill holes all over below the flange. This will allow water to easily flow back into the reservoir.


Now take your tube support and insert it into the PVC pipe, and secure it by running screws through the pipe into the support, as shown below. At this point you can also secure the flange to the PVC with the screws.



Now open your tube of 100% silicone. Apply a generous amount on the bottom side of the flange and insert the pipe into the bucket’s lid. Firming pressing it down, you should see silicone coming out from under the flange. This will ensure we have enough silicone applied.
Secure the flange with the nuts, bolts, and washers. Bolts should be tight but remember to not overtighten as this could crack the PETG flange. Once secure, using your finger and a paper towel/rag wipe off the excess silicone.




Now apply a generous amount of silicone around the net cup hole.


Press the net cup holder firmly against the PVC pipe. The silicone will hold it in place. Next get your screws and secure the holder to the PVC pipe as you did when tracing the holders.
Repeat this for all net cup holders, wiping the excess silicone off as you go.


Insert the ½” PVC into the tower and attach the adapter you chose for the water pump hose. Pictured below is a 3D printed one that actually failed so I got an adapter from my local hardware store instead.





Now apply a bead of silicone at the top of the tower and place your water distributor cap on top of the bead. No worries about cleaning this excess up as we will be applying more when putting the top cap on the tower!



Slide the ½” PCV pipe up through the water distributor and put on the ½” PCV coupler. You can use PCV glue or simple run a screw through it so it doesn’t fall out.



Next apply another generous bead of silicone around the bottom of the top cap for the tower. Then insert it on the PVC pipe until it comes in contact with the stoppers. Secure the top with 2 screws.


That’s it! Now wait the recommended amount of time needed for your silicone to set up as indicated on the tube. Mine was 24 hours of dry time.
After that transfer your seedlings into the tower, setup your time and watch your plants grow!



*I put my food grade bucket into another darker bucket to limit light exposure

UPDATE : I'm currently working on a bucket flange for the threaded bucket lids that Lowes sell. Be on the lookout for that in the files coming within the next few days!

These lids are much more solid and should carry the weight of the tower without the PVC going all the way down to the bottom of the bucket. That's the hope at least. That way there is more room for the pump which is kind of tight unless you get one that can fit inside of the 4" PVC pipe.

Hey everyone!
Here are the STL's for the threaded bucket lid.
Disclaimer - I have printed this but haven't drilled the lid and dropped it in place to test fit it. So just beware on that. The second file will go under the bucket lid to help stabilize the tower with the bolts/washers.
I wanted to get this up since I know @seesharpist is working on printing his tower and wanted the option out there if it was wanted.

Pics to come once I assemble this. Hopefully happening tonight.

Another quick note. Once the hole is drilled you'll bolt on the flange with smaller bolts in the flange holes that straddle the lid handle to secure it in place. Then put on the bottom bracket and secure that with longer bolts. I'll also use the length bolts I use once I buy them.

The HOPE is that you wont need to have the PVC pipe going all the way to the bottom of the bucket with taller towers since these lids are more sturdy. Anything 5' and shorter should be okay but I'll be going for an 8' tower with this.


@seesharpist found an issue with the bottom flange piece so I've modified and uploaded the updated version!

Hey all!
Here is another option for your tower(s) as requested by @seesharpist! The original Aeroponic Tower Cap is a total of 108mm (~4.25") tall. I made a shorter version which stands a total of 76mm (~3.00") tall.


NOTE - if you use this shorter version of the top it will not fit the entire 0.5" PVC coupler. You'll need to glue the coupler to the 0.5" PVC pipe and then cut it down so the tower top cap/bolt will screw into place!

Photo below shows the height difference in the original cap vs the short version.

I've got another design update for the towers! This time it's for the net cup holders. Version 1 is working well but as the plants matured throughout the season their roots caused a little bit of an issue with water backing up into the net cup and dripping over. This is/was a minor issue that can easily be resolved by wrapping the net cup in something such as aluminum foil, as I posted about awhile back here. So if you printed the v1 refer to that link if you find yourself with that issue. For me it was only the plants that had INSANE root systems.

Anyway, after playing around with the design v2 will hopefully resolve that issue by having a steeper angle. The v1 design had a 55° angle to expose more of the net cup inside of the PVC pipe and v2 features a 45° angle.
When using the v2, be sure you're using a longer net cup to ensure it's exposed into the PVC in order to provide nutrients to the plants.
The 2.75" net cups listed in the supplied section of this guide (also here) work great!

I just wanted to show an example of the new threaded bucket lid flange. I printed this ages ago it seems and finally built another tower with it. Doing this is MUCH sturdier than using the thin snap on lids. You don't need to have the PVC pipe going all the way to the bottom of the bucket because this lid supports the weight just fine! So this really opens up the bucket so it's easier for pump placement/fitment!

Thank you for sharing a great project. This will be my fist hydroponic system. How do you gather a water sample for testing with this? It would be great if there was a collector cup that inserted in an unused plant port.
I found this one but don't know how to modify it to fit the ports on your tower.

I was printing in Black and ran out. I switched to Yellow but after printing 12 of the holders I realized the yellow is rather translucent and the black blocks all light. I have never done any hydro or aeroponics but reading I see that algae can be a problem if light gets in and read some info that light isn't good for the roots. Should I not use the yellow PETG holders and wait until my order of Black PETG arrives and reprint?
