The Importance of Watering Cannabis Plants

Water is vital for the health of any plant, and cannabis plants are no different. In fact, water is especially important for cannabis plants because they are grown in soil, which can quickly become dry and deprived of nutrients.

Without enough water, cannabis plants will not be able to absorb the nutrients they need from the soil, and they will eventually die. That’s why it’s so important to water your cannabis plants regularly and make sure they have access to a constant supply of fresh water.

How often you need to water your cannabis plants will depend on a number of factors, including the type of soil you’re using, the size of your plants, the climate you’re growing in, and how much light your plants are getting. In general, though, most cannabis plants need to be watered at least once a week.

If you’re not sure how often to water your cannabis plants, it’s always better to err on the side of caution and water them more often than less. Your plants will let you know if they’re getting too much water by developing yellow or brown leaves. If this happens, simply cut back on the amount of water you’re giving them until their leaves return to normal.

How Often to Water Cannabis Plants

How often you should water your cannabis plants depends on a few factors, including the size and type of pot you’re using, the type of soil, the temperature and humidity of your grow space, and how much light your plants are getting. In general, you should water your plants when the top inch or two of soil is dry.

Daily Watering

If you’re growing cannabis indoors, you’ll need to water your plants daily. The best time to water them is in the morning, so that they have all day to absorb the water and dry out before nightfall. If you’re growing outdoors, you can water your plants once or twice a week, depending on how hot and dry it is.

Weekly Watering

It’s best to water your plants with plain water once a week. This allows the roots to take up water and nutrients at their own pace, and helps prevent overwatering and nutrient burn.

If you’re using grow lights, you may need to water your plants more often, as the light can dry out the soil faster. If the soil feels dry to the touch, it’s time to water.

The Different Methods of Watering Cannabis Plants

There are different ways to water your cannabis plants, and each method has its own set of pros and cons. You can water your plants with a water bottle, a watering can, or a hose. You can also water your plants using automatic drip irrigation or a wick system.


Top-watering is probably the most common method of watering cannabis plants, especially for beginners. It’s easy to do and doesn’t require any special equipment. All you need is a water bottle or can with a spout or nozzle.

To top-water your plants, simply wet the soil around the base of the plant until it is evenly moistened. Be sure not to drench the soil; you want it to be moist, not wet. Allow the top layer of soil to dry out before watering again.

The main advantage of top-watering is that it’s easy to see when the plant needs water. The soil will look dry and lighter in color when it needs to be watered. The downside is that, if you water too much, the plant can become waterlogged, leading to problems with root rot.


Bottom-watering is a method of watering your cannabis plants from the bottom up. To bottom-water, you will need a tray, saucer, or catch basin that is filled with water and then placed underneath your pots. The pots should then be placed on top of the catch basin so that the roots can soak up the water from the bottom.

This method is ideal for those who want to avoid over-watering their plants, as it allows the roots to only take in as much water as they need. It is also a good method to use if you are growing in containers that do not have drainage holes, as the excess water will be caught in the catch basin and will not flood the container.

Factors to Consider When Watering Cannabis Plants

Cannabis plants need water to grow and thrive, but too much or too little water can be detrimental to the plant. There are a few factors to consider when watering your cannabis plants, such as the type of soil, the size of the plant, and the weather.

The Size of the Plant

One of the main factors that will affect how often you need to water your cannabis plants is the size of the plant. A large cannabis plant will obviously need more water than a small one. If you’re not sure how much water your plant needs, a good rule of thumb is to give it about 1 liter (or quart) of water per day for every foot tall that it is. So, if you have a 3-foot tall plant, it would need 3 liters of water per day.

The Potting Mix

The first factor to consider when watering cannabis plants is the potting mix. The type of potting mix will affect how often you need to water your plants. For example, if you are using a well-aerated mix, such as a mix of perlite and coco coir, you will need to water more often than if you are using a dense mix, such as soil.

The second factor to consider is the size of the pot. A small pot will dry out more quickly than a large pot. This is because the roots of the plant take up more water from a small pot than from a large pot.

The third factor to consider is the temperature and humidity of the room. If the room is warm and humid, the plant will lose water more quickly than if the room is cool and dry.

The fourth factor to consider is the stage of growth of the plant. During the vegetative stage, plants will use more water than during the flowering stage.

The fifth factor to consider is whether or not you are using any supplements that contain nitrogen. Nitrogen-rich supplements will cause the plant to use more water than if you are not using any supplements at all.

The Climate

There are many factors to consider when determining how often to water your cannabis plants. One important factor is the climate. For example, if you live in an area with high humidity, you will probably need to water your plants more often than if you live in a dry climate. If you live in a cold climate, you will probably need to water your plants less often than if you live in a warm climate.

Signs That Your Cannabis Plant Needs Water

Water is essential for the growth of your cannabis plant. The plant needs water to absorb nutrients from the soil and to produce energy through photosynthesis. When watering your plant, you should always check the soil before giving it a drink. There are a few signs that your plant is thirsty.

The Plant Is Wilting

One of the most common and most easily identifiable signs that your cannabis plant needs water is wilting. If you see that your plant’s leaves are starting to droop down, this is usually a sign that the plant is not getting enough water.

Another way to tell if your plant is thirsty is by checking the soil. Stick your finger in the soil up to the first knuckle. If the soil feels dry, it’s time to water your cannabis plant.

The Leaves Are Drooping

If the leaves of your cannabis plant are drooping, it’s a good indicator that the plant is thirsty and needs water. Check the soil before watering to make sure that it is indeed dry. If the soil is still moist, wait a little longer before watering again.

The Leaves Are Turning Yellow

One of the most common edibles, and one of the first that most people learn to cook with, is brownies. If you’re new to cannabis cooking, you might be wondering how to make them. You can find brownie recipes that don’t require any cannabis at all, but if you want to infuse your brownies with THC, you’ll need to know a few things first.

The leaves are turning yellow: One of the easiest ways to tell if your plant needs water is to check the color of its leaves. If they’re starting to turn yellow, that’s a sign that the plant isn’t getting enough water.

The leaves are wilting: Another way to tell if your plant needs water is to check the leaves for wilting. If they’re drooping or drooping down, that’s a sign that they’re not getting enough water.

The plant is stunted: If your plant isn’t growing as tall as it should be, that could be a sign that it’s not getting enough water.
