V2 is now available here - Modular Hydroponics Tower V2

Parts are compatible with V2 if you want to mix and match. Main improvements are:

• New Lid with leaks removed
• No longer requires heat-inserts, just self-tapping screws
• Embossed design around modules.
• Pots, spacers and blanking panel now included.

The base and clamp and core tower has remained the same as this V1.

This modular hydroponics tower lets you grow a large amount of plants without the need of lots of room. Each module fits 3x 50mm (2 inch) pots and has the water tube running up the middle. Just stack as many modules as you require.

The pots are available on Amazon / any garden centre. There are also pots available to download on Makerworld that will fit this model such as these: [https://makerworld.com/en/models/207547](https://makerworld.com/en/models/207547) 

Each module is designed to fit 3 M3x4x5 heat-inserts and bolt together using M3 x 6mm bolts.

I designed this to fit on a small 3D printer, with a build area required of 170 x 170.

At the bottom of the stack you need the Base with a 16mm barb fitting and the optional base clamp (to clamp to the other side of a container lid) and attach it to a submersible pump.

At the top you push in the shower head and bolt on the lid. I drilled out the holes of the top module to 4.5mm to fit in 3 heat-inserts to make this secure but it does function fine without the lid bolted down.

Have fun growing!
