Experimenting with two nozzle types for the hydro tower, the goal was to reduce the flow strength by mimicking a mist nozzle while retaining saturation. The pressure is not enough for it to fully mist with most pumps you would use in this system, but these nozzles should be an improvement over the original nozzle in terms of reducing the water speed.

Spin Nozzle

Video: Here

More flow than the Aero Nozzle, requires the rounded lid. Has a nice wide cone as the water comes out and flows evenly. Requires that the middle piece be inbetween the base and the head. Base and head are screwed together so make sure your tolerances are tuned. Requires rounded lid (original is too short).

Note: Remixed from an existing nozzle somewhere but could not find the original maker anymore, will update if I do and credit them.

Aero Nozzle

Mimicks a misting nozzle, but the pressure is not quite there with our pumps, but it does restrict the flow and produces a thin cone of water. The rounded lid is recommended (so that the water flows evenly down the sides), but it does work with the original lid as well.
