Some of the greenhouses on island are to CONTROL the amount of water.... there are many years that have drought conditions for a month or more, and sometimes (even a month or 2 after a long drought) when we can have enormous rainfall.... These extremes can really tax plants, esp normal sub tropical to tropical varieties that are happy with 45"-60" of rainfall per year... with a good temp/humidity control system and a good irrigation system (some use gravity fed catchments with augmentation) you can create a truly ideal environment for a target plant.
