Three ice cubes equal about 1/4 cup of water.

For larger containers, increase the number of ice cubes to match the size of the pot.

Vibrant, green roots are hydrated.

However, do not leave orchids (or any plant) in standing water.

No, orchids typically burn in direct sunlight.

Watering orchids thoroughly once they are dry is more effective.
