System Features:

Modular, Stackable Design: Alternate Part A and Part B to build the tower to your desired height. (A and B parts are labeled in the print)

Threaded Assembly: All segments connect using integrated threads—no glue or tools needed. Just screw parts together for quick, secure assembly.

2" Grow Cells: Each grow cell is 2 inches in diameter and angled at 45 degrees to support optimal growth and efficient water flow.

Optimized Tier Rotation: Each tier is rotated 60 degrees from the one below it to maximize spacing, airflow, and light access.

Hydroponic Drip System: Designed for a ½" PVC pipe as the central water delivery line, connected to a submersible pump.

Reservoir Compatible: Fits on top of a standard 5-gallon bucket or your preferred water container.

Custom Cell Use: Use pod cups in active grow sites, and seal unused ones with the included blank plugs.

Support-Free Printing: All components are optimized to print cleanly without the need for support material.

Ideal for herbs, leafy greens, and small fruiting plants, this system offers a scalable, efficient, and clean solution for vertical hydroponic growing. Print only the parts you need and expand your garden as you go!

3D printing settings Assembly Instructions Parts to Print:

1× Base

1x Part A

1× Threaded Mount

1× Nut

1× Cap

1× Spreader/Deflector

As many Part B segments as needed

Pod Cups (for each active cell)

Blank Plugs (for any unused cells)

Assembly Steps:

Prepare the Reservoir: Cut a 4-inch hole in the center of the lid of a sturdy 5-gallon bucket.

Install the Base Mount: Thread the Threaded Mount into the bottom of the Base. You may apply glue for a permanent joint. Feed the mount through the hole in the bucket lid and secure it using the Nut from below.

Stack the Grow Segments: Thread Part A in to the base. Stack as many Part B pieces as you like, threading them together in your desired height configuration. Screw the Spreader/Deflector onto the topmost grow segment.

Set Up the Water System: Place your submersible water pump in the bucket and connect it to a ½" PVC Feeder Pipe using the proper fitting. Place the lid (with the base mounted) back onto the bucket. Thread your A and B tower segments onto the base, guiding the feeder pipe through the center of the spreader as you go.

Cut Feeder Pipe to Length: Trim the feeder pipe so that it extends about 1 inch above the spreader.

Cap the Tower: Screw on the Cap to finish the assembly.

Install Pods or Plugs: Insert Pod Cups into active grow cells. Seal any unused cells with Blank Plugs.

Your Modular Hydroponic Tower Garden System is now fully assembled and ready to grow!
