If you’re thinking about building a Hydroponic system, here’s an awesome one that is portable! It’s made with PVC and lumber
There are 12- 3″PVC tubes in all, each holding 14 plants.
This type of system is good for non-fruiting plants, such as basil, parsley, thyme, rosemary, etc. Fruiting plants need support and also have too large of a root ball, which impedes water flow.
