How Much Water Does A Cannabis Plant Require?

Just as with human beings, a cannabis plant needs to have water in order to thrive and survive. However, if your cannabis plant gets too much water or even not enough water, it can die. It is not easy to find that right balance, but it is crucial to do so in order to get a better yield or harvest. The living plant is 80% water weight. Water is essential to transport nutrients in the soil, allowing it to go throughout every area of the plant.

Water is also good for regulating the temperature throughout the plant via transpiration. 1% percent of the absorbed water breaks down to provide the plant with hydrogen and in combination with carbon dioxide; carbohydrates are formed during the photosynthesis process. The remainder of the water will then diffuse to the plant's foliage where the transpiration process takes place. The transpiration process is very essential to the plant's life because if it doesn't occur, the leaves will begin to wilt and the cannabis plants will eventually die. The question is how much water does a cannabis plant require? Let's dig in.

No Fixed Rule

Well, no rule is fixed about how much water a cannabis plant needs. One thing that affects this decision is the geographic and then the other is your gardening situation. If you grow cannabis plants in some northern areas in Europe, you may only need two liters of water every three days because in this area, the humidity is well preserved by the soil. In Spain, the same cannabis plant may need triple that amount of water because in this area, the sun quickly dries out the soil. If the soil drains quickly, then you have to replenish it with water more often. If you use clay soil, it will drain slowly and so overwatering could become an issue here.

The Draining

The soil drainage for cannabis plants can be easily tested by pouring water into a 30centimeter hole that you would have dug. If the water takes less than a minute to drain, then you can bet that the soil is good. If the soil takes about one hour to drain, the soil could be described as clay or compacted soil. This means you have to improve or replace the soil. However, there are some essential factors to be considered. For instance, the plant's size, the cannabis size, the humidity, the air circulation, the temperature and the vegetation will become important to the amount of water required for your cannabis plants.

Visual Signs

And so rather than trying to consider a formula that includes all these factors, the easiest thing to do is to pay attention to the visual signs of the cannabis plants. This will give you a good idea of the status of the plant as it relates to the amount of water needed. You will be able to figure out what the plants are lacking. Once the lower foliage indicates that the plants are diminishing and no longer resilient, it is time to give them water. However, the ideal situation would be to give the cannabis pants water before they show signs of being depleted. If your plants are directly in the soil and it looks or feels dry, then water should be slowly added to the soil. If the plants are in a cannabis, you only need to add little water at a time, making sure that there are holes to drain the excess water.

Rule of Thumb: Keep a Close Watch

The rule of thumb is not to allow the soil to get too dry or too wet. That means, you should not over water your cannabis plants. On the other hand, if you don't water your plants enough, the foliage will begin to droop and eventually bend over and die.
