Answer 1

This is, both, simple and complicated at the same time. There will be no set amount to water a plant, since the amount of water it requires will rely on the specific plant, its watering needs, and environmental factors such as temperature and humidity.

The best general rule of thumb is to water when the top two inches of soil are dry, whether this be in container, or in ground.

With this being said, it will be hard to water all plants simultaneously since they will all have a different requirement, unless they are all the same kind of plant and same age.

Determining when your plants need water will require looking at each individual container unless you know for sure that they will all dry out each day, therefore will be required a watering each day.
