How do underground gardens work?

The concept behind an underground garden is that hydroponics is applied with a water re-circulation system that allows the same amount of water to used again and again so drought never becomes a problem.

Is a sunken greenhouse better?

The biggest benefit of a sunken greenhouse is its use of passive energy. The sun can work much more effectively than it does in conventional, surface-built greenhouses because if has a lot less work to do to heat the greenhouse to ideal growing temperatures.

Can plants survive underground?

Thanks to their built-in cooler of food resources, some geophytes can grow entirely underground, even after most people might assume they’re long gone. For some geophytes, this dormant period – a plant’s version of hibernation – is more than a time for rest and relaxation.

How can I heat my greenhouse for free in the winter?
