Hello everyone

Currently I am working in a project which does not have an irrigation system, and will be watered with collected water from rainfall.

"Once a week (more often in the growing months and on hot summer days), the planting area must be watered with a garden hose. A cistern is provided in the outdoor areas for this purpose, which is fed with rainwater from the roof drainage system. In addition, the planting areas are covered with a layer of lava to prevent excessive evaporation."

Does this description fit Option 1 ?

I have read some coments regarding this concern but I have not found a concret answer.

Thanks
