More info on the parts and assembly

This 'distribution hub' is for providing automated, tailored hydroponics distribution from up to 4 inputs out to up to 4 outputs. I use mine to distribute from three different reservoirs (one just water, one nutrient mix for vegetative and one nutrient mix for fruiting) to four 'targets', currently two tomato plants and two cayenne pepper plants.

This upload contains the base for the assembly. The valves are a re-use of an existing design. You can find more info on the valve assemblies here.
