Using commonly available schedule 40 PVC components, growth chambers may be made in varying height and widths from 8 to 24 inches. These may be connected to a tee using a 1/2 inch bulkhead fitting and pex tubing, from there connected to two 1/2" to 3/4 manifolds for ebb and flow of the nutrient solution. These double as feet to keep the assembly stable. At the top a standard Par38 LED DMX stage light is installed to provide light in varying spectra and intensity for the experiment. All connectors should be sealed air tight.
