This hydroponic system is based on Dani's Indoor Grow Tower but adapted to a large 13-gallon tank readily available on Amazon or big box stores in the US (Mighty Tuff 13 Gallon). I also added a trellis system to the unit to allow plants to grow and climb on when getting heavier.

The lid is printed in 4 pieces due to size and screws onto the storage container just like the original lid that comes with it. The rubber seal can be removed from the original lid and installed onto the printed lid.

I also added a light holder to the unit if used inside to mount a hydra-style LED grow light.

I am using a submersible pump that is strong enough to add several more towers to the unit.

I also designed blind caps for unused pods to keep light out and prevent algae growth.
