How to Water a Marijuana Plant
Cannabis is a tough plant and most strains will be very forgiving if you lax with their water supply. However, consistent water stress can be detrimental to the health and the ultimate quality of the plant. It is, therefore, imperative for every grower interested in fresh, robust and healthy leaves to know how to water the plants in the right manner and at the right times.
Here are some key factors to help you out:
Hydration is very important for Cannabis Plants
Cannabis plants require a lot of water, especially when they are just about to flower. As a general rule, cannabis plants should never be allowed to go for long without water. Depriving them of water for long will hamper their nutrient intake and as a result, the growth will be stunted, leading to poor yields.
While watering the plants however, caution should be taken to ensure you don’t supply too much water since this may lead to other undesirable conditions such as botrytis and root rot amongst other problems. Ideally, you should determine the critical amount of water needed by the plant based on the strain, the size, as well as the stage of growth.
Know when to water the plants
Just as knowing the amount of water to be supplied to the plant is crucial, it is vitally important to know when you should do the watering. Most growers agree that the best time to water the cannabis plant should be at night time or early in the morning.
It is argued that watering at night or earlier during the day will allow the plant adequate time to utilize the nutrients effectively since most of the plant processes depends on sunlight and this is available only during the day.
Watering when the sun is up is, however, not encouraged, since in the natural set up, precipitation never take place then sun is shining. Besides, the water droplets which will remain on the leaves will act like magnifying glass when sunlight falls on them and this may lead to leaf burn.
The frequency of cannabis plants watering
Now that you have an idea on how much water is necessary and when the times to apply it are, the next thing is to work out the frequency of the application. The recommended frequency is twice every day on days when the temperature is high and the humidity is low. But as the plant continues to mature and approach flowering, the frequency should be reduced as the quantity is increased. When the plant reaches full flowering, the marijuana plant must be watered once every two to three days.
The ideal frequency for watering the plant should be determined after you evaluate the moisture levels in the soil or the growing medium. Ideally, the medium should be dry on the top and slightly dump beneath the surface. If the medium is dry up to 5cm beneath the surface, then the plant is probably too dry and the plant may be undergoing water stress. In such a case, you should supply water to restore moisture content of the soil and avoid further water stress to the plant.
