Marijuana as a plant requires water, nutrients, light, and air to grow healthy and produce healthy products. Water has a fundamental role since it helps the plant absorb nutrients from the soil and move them up to other parts of the plant. And so, do you know how to water a marijuana plant accordingly? Our guide will go over everything you need to know about watering marijuana.
Watering cannabis plants sounds like an easy job, yet many growers don’t know that using the wrong technique results in plant growth failure. Overwatering is the main mistake they make as too much water obstructs the plant oxygen intake, drooping leaves, and yellowing leaves. Again, under watering of the plant may make it wither due to thirst.
Maintaining a balanced water supply is essential for the plant, and in this article, I shall share different tips on how to water your cannabis plant.
Tips for watering marijuana plant:
1. Water sourcing
The quality of water given is also a determinant of the growth of the cannabis plant. Depending on your location, different waters contain different minerals, bacteria, and other pollutants which could shock the plants. Still, these waters may have high pH levels, which could be toxic to the plant. The best thing is to measure the water pH level and adjust accordingly.
To avoid this problem, you can choose to use filtered or reverse osmosis water. These filters eliminate almost 98%of dissolved minerals in your water, and your plant gets clean water.
2. When to water a weed plant
You need to know the amount of water each plant needs and the proper water balance required to avoid overwatering and under-watering. This will be essential for overall cannabis healthy growth. However, the amount of water required depends on various factors such as the phase of life stage, strain used, soil type, water pH level, and method of growing used (indoor or outdoor).
Most growers prefer watering marijuana plants during the nights or early morning before sunlight since it allows plants to utilize all the minerals in the water. Additionally, fewer plant physiological processes, such as photosynthesis, are occurring due to their dependence on sunlight, enhancing minerals absorption.
During the day, when sunlight is up, it’s not encouraged to water. This is simply because it interferes with the plant’s physiological processes as the droplets in leaves magnify sunlight rays and may result in leaf burn.
3. How to tell if the cannabis plant is thirsty
When cannabis plants lack enough water, they start experiencing some deficiencies, which help you to know. Such deficiencies include;
Drooping makes your plant and leaves look sickly and lifeless due to a lack of enough water. This symptom is easy to spot. Also, it’s good to know that even drooping may occur due to overwatering. However, for overwatered plants, their leaves turn dark green the plant curl downwards and look heavy.
Lack of water that causes drooping and wilting leaves also displays shows discolored yellow/brown leaves. Normal healthy cannabis in its early stages of growth should display yellow leaves compared to the old plant in its last stages, which turns yellow naturally.
Check the soil dryness
the cheapest way to check your soil dryness is by injecting your fingertips into the soil, and if the texture of the soil is dry, it shows it needs water. However, this method won’t show the correct amount deep down. Weighing of the pot/medium may be able t tell you the amount, and you can proceed according to your feelings
4. How much water do cannabis plants need
Watering cannabis determines the kind of plant you will have, from the seedling to a full-grown plant. How much water is required will be influenced by the following;
Stage of the plant
How much water the cannabis plant requires will vary from stage to stage since seedlings require less water than well-grown plants. More developed plants require frequent watering due to their well-established root system and other physiological processes.
The medium of growing you use will determine the amount of water the soil will hold. Growing in containers will need to make holes at the bottom to release excess water, which may lead to roots rot and fungus development which hinders water and nutrient absorption. Also, plants require rich, well-draining, and air circulating soils for them to flourish since these soils balance water retention and drainage well.
Other factors such as light intensity, humidity, and health of the cannabis plant will also determine the amount of water required
5. How regular to water the weed plant
Since we now understand when and how much water is required, it’s time to know the frequency of this application. The frequency will depend on climatic conditions, growth medium, strain, and growth method.
Ideally, it’s advised to water twice a day when temperatures are high and low humidity. However, as a plant’s growth progresses, frequency should reduce since the flowering stage requires less water for buds growth and avoids the development of molds in buds.
The dryness of the soil should determine the regularity of watering. If the soil is too dry, it may cause stress to the plant, and you can remedy this by adding water.
6. Collecting water runoff
Excess water drained from the containers used for growth should be well channeled out, and the plant not be submerged in waters that hinder air circulation and gives pathogen areas to flourish.
This can be collected by using slanted/inclined trays that dispose of water immediately after being released. You can also use syringes, paper towels to suck off water from the trays.
7. The right pH monitoring
Cannabis plants do well in a pH range of between 5.5 and 6.5 levels. Before watering weed plants, you have to measure the pH levels of the water to avoid lowering or increasing pH levels which determine the capacity of nutrients absorption in the plant.
Some other factors usually cause pH-related problems, but mainly from the actual water provided to the plant. You can determine the pH level of water runoff by using a pH meter. If the soil becomes too acidic or alkaline, the plants cannot absorb all the available nutrients and minerals, resulting in stunted growth. The pH meter can be used as a method to remedy pH-related problems since you will be able to maintain an optimum level. Hopefully we were able to go over all the tips you need for watering marijuana.
