The Greenhouse is used to care for and over-winter tender perennials, tropicals and succulents.
Two swamp coolers provide evaporative cooling. When temperatures get too high, roof vents open automatically.
The floor of the Greenhouse is a French drain that funnels water into the main garden system. It is very easy to keep clean.
Look for ways we propagate plants by grafting.
Or other techniques such as using a plastic tub as an inexpensive hothouse for starting plants from cuttings.
You will see many interesting plants in the Greenhouse such as this Jade plant, a pencil cactus, and orchids.
