How Often to Water Marijuana During the Flowering Phase Watering cannabis at the flowering stage can be difficult for cultivators since the plant is mature, has various nutrient needs, and typically absorbs water more quickly because it is producing flowers.
We recommend watering every two to three days, but you should always test the soil to see if your plant needs water. There is a straightforward method to remember when to water marijuana: When the soil is dry to a depth of one inch, you can water. If plants are wilting, you may water them. How —For established plants (and vegetative plants), thoroughly saturate the soil with water so that it permeates.
Soak even the deepest portions of the soil. Measure — maintain a record of your irrigation regimen! Record this information in a log so you can track your plant’s development over time and determine how it responds to different watering phases.

How frequently should I spray my weeds?
Indoors: – Indoors, every day may be whatever you want it to be; you have control over the sun and the weather. Indoors, you must spray with the lights on but not directly over the plants. They must be removed from the grow tent or light area when the lights are on.
Remove them from the light and wait for the surplus drips to evaporate. Once they are dry, you may set them back in the grow tent without worrying about them catching fire. If you need to water, you should do it when the sun begins to rise. If you have a large grow room or cannot remove the plants to spray them all, set the lights as high as possible and keep one on so you can see.
Spray them all, reserving your spray for the ones beneath the light. Switch off that light and turn on one where the plants have dried, and then spray the remaining plants. There will always be a set period when you must spray and water your plants, regardless of what you’re cultivating. 
Should I water my weed in the evening?
Can You Water Cannabis Plants at Night? – While there is no consensus on the answer to this topic, we do not advocate watering your plants at night.

The Advantages of Misting – Many of our houseplants originate in the tropics, where humidity levels are quite high. According to Trey Plunkett, a Lowe’s lawn and garden professional, “the air inside our houses is often dry.” Misting houseplants is an easy and efficient method for increasing humidity.
