Here is a homemade vertical hydroponics system that is made from PVC pipes. This is not what I personally would call a vertical hydroponics system as the pipes are arranged horizontally. Nonetheless, it seems like it is a system that will be able to produce a substantial crop in a very small footprint.

This hydroponics system is based on the nutrient film technique (NFT), where hydroponic nutrients are pumped into one end of the pipe and then allowed to drain along the pipe, right through to the other end, where they are collected and recycled. There is one aspect of this hydroponics system that I don’t like, which is the way the water is left to free-fall into the nutrient reservoir at the end of each PVC pipe. This will undoubtedly cause a lot of splashing and therefore unnecessary loss of nutrients and water. I would have put some sort of down-pipe for the collection system to flow down.

Having multiple PVC pipes arranged vertically as in this design, a huge crop can be grown, although I was only able to recognise tomatoes and cucumbers.

Interestingly, all of the plants have been started in rock wool, and the rock wool cubes have been jammed into holes drilled in the PVC pipes, where they will sit indefinitely. There is no other growth medium (such as expanded clay) being used.

This system is also housed insided a very nice greenhouse, meaning it can be used to grow plants essentially all year round.
