20 cups Hydroponic tower, a system for 20 cups - four-way cup modules. Complete hydroponic tower system for 20 plants. 3D printed from PETG.

Hydroponic tower with 5 levels for four growing cups.
It allows you to grow 20 plants side by side indoors or outdoors. The material used is PETG, which is non-toxic and food-grade. Compared to PLA, it is UV—and temperature-resistant. It's great for indoors or outdoors, without any defects caused by sunlight or UV light.

You can increase the tower height by purchasing additional modules and cups. All are available in our store.

The tower has module levels with four cups each. It includes the top sprinkler module and lid. For convenience, there are two spacers: 40mm and 120mm.

Method:
The tower is built from interchangeable lockable modules. Inside the modules is a guide for the hose connected to the submersible water pump. The pump sits in the base with the nutrient liquid and pumps water up to the sprinkler at the top. Water then drips down, irrigates the plant cups, and circulates through the pump back to the top.

From 2025, we have changed the offering to provide a tower lid holder for a 5-gallon bucket (like Home Depot or Lowes) or a second option, a white food-grade bucket with a lid and tower lock adapter. The tower then sits on top of the holder above the bucket with the nutrient water and a pump inside that pushes the water through a hose to the top sprinkler for irrigation.


This tower model comes with a water pump and piping included.
