I want to build
Build rather than buying
Tube diameter, pump power, net pot size, channel slope: the figures that matter to build a system that works the first time, and that you can repair.
-
1
Choosing what to build
PVC pipe tower, wall of channels, NFT bench, DWC buckets: each system has its own flow and slope constraints.
-
2
Choosing the pump from its curve
The flow rate “at 0 m” is a trap: read the flow/head curve at the top of your setup.
-
3
Choosing the right containers
Food-safe material, opaque, rigid lid, drain at the bottom, drip tray.
-
4
Building a tower
Drilled PVC pipe, wall of channels or printed modules: plans, drilling and tests.
-
5
Building an NFT rack
A slope of at least 2%, flow rate set, manifold: get everything dialed in with plain water before planting.
-
6
Test for 24 to 48 hours with no plants
A tower that leaks when empty won’t get better once the roots are in.

Show off your build
Photos, dimensions, parts: your builds help those who follow as much as the guides do.
