Marijuana is a high-use water plant: grown outdoors, it requires more water than commodity crops like wheat, corn, soybean, or cotton.
According to research, a cannabis plant consumes around 22 liters (or 6 gallons) of water per day during the growing season, which takes place from June to October.
On the other hand, indoor cannabis cultivation may require only 10 liters (2.5-2.8 gallons of water per day per plant towards the end of the growing season.
When watering the plant in a pot, make sure the water soaks up the soil completely and wait until it’s almost dry before you add more water.
