Growing cannabis plants can be both exciting and intimidating, especially for beginners. One of the most crucial aspects that contribute to the health and yield of cannabis plants is their watering schedule. However, determining the right watering schedule can be perplexing, considering various factors at play, such as the type of soil, plant size, humidity, and temperature. Watering too little or too much can result in numerous problems that can harm your plants. In this detailed article, we’ll walk you through step-by-step on how to determine the right watering schedule for your cannabis plants, how often and how much to water, and troubleshooting watering problems. So, let’s dive in!
Factors to Consider
Contents
When it comes to determining the right watering schedule for your cannabis plants, there are several factors that you need to take into consideration. These factors can greatly impact how often and how much water your plants need. Understanding the various elements that can affect your plants’ water needs is crucial in ensuring that they get the right amount of water at the right time. Let’s dive into some of the most important factors to consider.
Type of Soil
When determining the right watering schedule for your cannabis plants, the type of soil you are using is an important factor to consider. Different soils hold water differently and have varying levels of nutrients. Clay soils tend to hold water longer, so you may need to water less frequently. Sandy soils, on the other hand, have poor water retention and require more frequent watering.
If you are using potting mix or coco coir, you will need to water more frequently as these soils tend to dry out quickly. However, they can also hold too much water if overwatered, so it is important to monitor the soil moisture level.
Another factor to keep in mind is the pH level of your soil. Cannabis plants thrive in a slightly acidic soil with a pH between 6.0 and 7.0. If the pH level is too high or too low, your plant may not be able to absorb the nutrients it needs even if they are present in the soil. It is important to regularly test the pH level of your soil.
In addition to the type of soil you are using, the size of your container also plays a role in how often you need to water. Smaller containers will dry out more quickly, while larger containers can hold more water and maintain moisture for longer periods.
Considering the type of soil you are using, as well as other factors such as container size and pH level, is crucial when determining the right watering schedule for your cannabis plants.
Size of Plant
Size of the plant is another important factor to consider when determining the right watering schedule for your cannabis plants. The size of the plant can affect how much water it needs and how often it needs to be watered.
To determine the watering needs of your plant based on its size, you can use the following general guidelines:
| Plant Size | Watering Frequency |
|---|---|
| Small (up to 12 inches) | Every 2-3 days |
| Medium (12-24 inches) | Every 3-4 days |
| Large (24 inches or more) | Every 4-7 days |
However, it is important to note that these are general guidelines and each plant may have unique watering needs based on other factors such as the type of soil, humidity, and temperature. Be observant and monitor your plant’s growth and behavior to adjust your watering schedule if necessary.
Overwatering can be a common issue with larger plants because they often have a larger root system that retains more water. This can lead to root rot and other problems. It is important to water your plant to the appropriate level based on its size and not to exceed it.
Humidity
Humidity is an important factor to consider when determining the right watering schedule for your cannabis plants. Humidity refers to the amount of moisture in the air, and it can have a significant impact on how quickly your plants lose moisture through their leaves. Here are some things to keep in mind when it comes to humidity:
- Low humidity: In low humidity environments, plants can lose moisture quickly, which can cause them to wilt and dry out. This can lead to problems with overwatering, as growers may be tempted to water more frequently in an attempt to compensate for the lack of moisture in the air.
- High humidity: In high humidity environments, it can be more difficult for moisture to evaporate from the soil, which can cause plants to become waterlogged and develop root rot. Additionally, high humidity can create conditions that are favorable for the growth of mold and other pathogens.
- Ideal humidity: For cannabis plants, the ideal humidity range is typically between 40-60%. This range allows for moderate moisture loss through the plant’s leaves while still providing enough moisture in the air for healthy growth.
Monitoring humidity levels can be done using a humidity meter, also known as a hygrometer. These devices are inexpensive and easy to use, and can provide valuable information about the growing environment. If humidity levels are too low, growers may need to consider using a humidifier to raise the moisture in the air around their plants. If levels are too high, a dehumidifier may be necessary to reduce the moisture content. By keeping humidity within the ideal range, growers can help ensure healthy growth and prevent watering problems.
Temperature
Temperature is another crucial factor to consider when determining the right watering schedule for your cannabis plants. The temperature affects the rate at which the water in the soil evaporates and gets absorbed by the roots.
Here is a table showing the ideal temperature range for cannabis growth:
| Stage of growth | Ideal temperature range (°F) |
|---|---|
| Seedling stage | 70-78°F |
| Vegetative stage | 70-85°F |
| Flowering stage | 65-80°F |
During the Seedling stage, it is important to maintain a temperature range of 70-78°F to ensure proper root development and healthy growth. In the Vegetative stage, the ideal temperature range is slightly wider and falls between 70-85°F. This temperature range provides the perfect conditions for the plant to grow and develop before flowering. During the Flowering stage, the ideal temperature range is narrower, ranging from 65-80°F. This range allows for proper development of the flowers without damaging them or hindering their growth.
It is important to keep these temperature ranges in mind when determining the watering schedule for your cannabis plants. The hotter the temperature is, the more often you will need to water your plants, as the water will evaporate at a faster rate. Conversely, if the temperature is cooler, the rate of evaporation will be slower, so your plants will require less water. It is crucial to monitor the temperature levels regularly and adjust your watering schedule accordingly.
In addition to affecting the watering schedule, high temperatures can also lead to other issues such as increased chances of pests and mold growth. It is important to maintain an ideal temperature range not just for watering but for overall plant health.
How Often to Water
One of the most crucial aspects of growing healthy cannabis plants is providing them with the right amount of water. However, determining the correct watering schedule can be a perplexing task for many growers. It’s not enough to water your plants whenever they look dry – you need to consider various factors such as the growth stage, soil type, size of the plant, and environmental factors. In this section, we will discuss how often you should water your cannabis plants during different growth stages, and provide you with insights on how to avoid common watering mistakes.
Seedlings and Clones
When it comes to watering seedlings and clones, it is crucial to get it right. These delicate plants are not yet fully developed and cannot handle the same amount of water as mature plants. The goal is to keep the soil moist but not soaked, as overwatering can cause the young roots to rot.
The amount and frequency of watering will also depend on the type of soil used. For example, if the soil is a mix of peat and perlite, it will dry out faster and may require more frequent watering.
Here is a table outlining a general guideline for watering seedlings and clones:
| Age of plant | Frequency of watering | Amount of water |
|---|---|---|
| 0-2 weeks | Every 2-3 days | 1-2 tablespoons |
| 2-3 weeks | Every 3-4 days | 2-3 tablespoons |
| 3-4 weeks | Every 4-5 days | 3-4 tablespoons |
| 4-6 weeks | Every 5-7 days | 4-6 tablespoons |
It is important to keep a close eye on the plants and adjust the watering schedule as needed. If the plants are showing signs of overwatering, such as droopy or yellowing leaves, decrease the frequency and amount of water. If the plants are showing signs of underwatering, such as wilting or dry, brittle leaves, increase the frequency and amount of water.
The key to watering seedlings and clones is to start with small amounts of water and gradually increase as the plants develop. Attention to soil type, signs of over or under watering, and plant age are all critical factors to consider when determining the right watering schedule.
Vegetative Stage
During the vegetative stage, cannabis plants are growing rapidly and require more water than they do during the seedling stage. However, it’s important not to overwater them, as this can cause root rot and other problems. Here are some guidelines to follow for watering your cannabis plants during the vegetative stage:
- Check the soil: Stick your finger into the soil about an inch deep. If it feels dry, it’s time to water. If it still feels moist, wait a day or two before watering.
- Water deeply: When you do water your plants, give them enough water to saturate the soil and run off the bottom of the container. This will ensure that the roots are getting enough water and encourage them to grow deep into the soil.
- Water less often: As the plants get larger, you can water them less frequently but give them more water each time. This will encourage the roots to grow deeper into the soil to find water.
- Watch for signs of overwatering: If the leaves start to turn yellow and wilt or the soil feels waterlogged, you may be overwatering your plants. Cut back on watering and allow the soil to dry out a bit before watering again.
- Humidity: During the vegetative stage, it’s important to maintain a moderate level of humidity to prevent the plants from drying out. Aim for a humidity level between 40% and 70%.
- Fertilizer: During the vegetative stage, your plants will benefit from regular applications of fertilizer. However, be careful not to over-fertilize, as this can cause nutrient burn and other problems.
By following these guidelines, you can ensure that your cannabis plants get the right amount of water during the vegetative stage and grow healthy and strong. Remember to always monitor your plants closely and adjust your watering schedule as needed to meet their changing needs.
Flowering Stage
During the flowering stage, your cannabis plants will require less water than during the vegetative stage. This is because the plant is no longer focused on growing new leaves, but rather on producing buds. However, it is still important to ensure that your plants are receiving enough water to support the growth of these buds.
When determining how often to water your plants during the flowering stage, it is important to consider the type of soil, size of the plant, humidity, and temperature, as discussed previously. It is also recommended to check the moisture level of the soil regularly, and adjust your watering schedule accordingly.
Here is a general guideline for watering during the flowering stage:
| Plant Size | Amount of Water | Frequency |
|---|---|---|
| Small | 1-1.5 liters | Every 2-3 days |
| Medium | 2-3 liters | Every 3-4 days |
| Large | 4-5 liters | Every 4-5 days |
It is important to note that these are just general guidelines, and you should always adjust based on the specific needs of your plants. Keep an eye out for signs of overwatering, such as yellowing leaves or slow growth, and adjust your watering schedule accordingly.
During the flowering stage, it is also important to use the right watering technique. One technique that many growers swear by is known as “bottom feeding.” This involves placing your potted plants in a container filled with water, and allowing the plants to absorb water through the drainage holes at the bottom of the pot. This technique ensures that the roots are receiving water directly, and can help prevent overwatering.
Watering during the flowering stage is all about balance. You want to provide enough water to support the growth of your buds, but not so much that you risk overwatering. By considering the factors discussed earlier and adjusting based on the specific needs of your plants, you can ensure that your cannabis plants thrive during this crucial stage of growth.
How Much to Water
One of the most important aspects of watering your cannabis plants is determining the appropriate amount of water to use.

So, let’s dive in and learn how to water your plants according to their unique development stages and individual root growth.
Root Development
When it comes to watering your cannabis plants, understanding root development is crucial. Strong roots are essential for healthy, vibrant plants. Here are some tips to help promote good root development:
- Start with a small amount of water: During the early stages of a plant’s life, it’s best to give it just enough water to keep the soil moist. Overwatering at this stage can lead to root damage and stunt growth.
- Use a well-draining soil: A properly drained soil is essential for healthy roots. Soil that holds water can lead to root rot and other problems. Adding perlite or vermiculite to soil can promote good drainage.
- Water deeply: As your plant grows, it will need more water. Water deeply, so the roots have a chance to grow and reach deeper into the soil. Shallow watering can lead to weak, shallow roots.
- Don’t water too frequently: Overwatering can drown the roots and lead to various problems. Instead, let the soil dry out between watering. This can encourage the roots to grow deeper in search of moisture.
- Feed the roots: In addition to water, your plants need nutrients to thrive. Use a high-quality fertilizer or nutrient solution to provide the essential nutrients required for optimal root growth and development.
By following these tips, you can ensure that your cannabis plants have strong, healthy roots, which will lead to a good yield. Remember that every plant is unique, and it may take some experimentation to find the right watering schedule for your specific situation.
Watering Techniques
When it comes to watering, there are a variety of techniques you can use for your cannabis plants. Each technique has its own advantages and drawbacks, so it’s important to find the one that works best for you and your specific growing environment. Below are some popular watering techniques and the benefits they offer.
- Top-Down Watering: This technique involves pouring water directly from the top of the plant’s soil. This is a common method for smaller plants or those grown in soil.
- Bottom-Up Watering: As the name suggests, this technique involves watering from the bottom of the plant by placing the container in a shallow tray filled with water. The water is then absorbed upward through the plant’s roots. This is a great technique for soils that drain poorly or for plants grown in hydroponic systems.
- Drip Irrigation: This is a method that uses small tubes to deliver water directly to the plant’s roots. This is a great choice for larger plants or those that are grown in hydroponic systems. The main advantage of this technique is that it ensures the water goes directly to where it is needed and reduces the potential for overwatering.
- Flood and Drain: This technique floods the plant’s roots with water intermittently, allowing the soil to dry out between watering cycles. It’s a great method for hydroponic systems and can be used with cannabis plants grown in soil as well.
- Aeroponics: This technique uses misters to mist water directly onto the plant’s roots. It’s a great method for those growing in hydroponic systems and it reduces the risk of overwatering.
Regardless of the technique you choose, it’s important to water your cannabis plants slowly and steadily, allowing the water to soak in gradually. This ensures that your plants are receiving the amount of water they need without the potential for overwatering.
Troubleshooting Watering Problems
One of the biggest challenges that cannabis gardeners face is determining the right watering schedule for their plants. Overwatering and underwatering can both cause serious damage to your plants, which is why it’s important to pay close attention to their needs. However, even the most careful growers may encounter some watering problems along the way.

So, let’s dive into the murky waters of watering woes and emerge with solutions to help your plants thrive.
Overwatering
One of the most common mistakes that novice cannabis growers make is overwatering their plants. Overwatering can cause irreparable damage to the roots of your plants, ultimately killing them. But how do you know if you’re overwatering your plants? Here are a few signs to look out for:
| Signs of Overwatering | What it Means |
|---|---|
| Yellowing leaves | When your leaves turn yellow, it is usually a sign that your plant is receiving too much water. Overwatering can cause the roots to become saturated and unable to absorb nutrients, resulting in yellowing leaves. |
| Drooping leaves | Overwatering can cause the leaves to become heavy and droop, as the roots are unable to support the weight of the plant. This can also lead to nutrient deficiencies and other problems. |
| Mold or mildew | Overwatering can create the ideal environment for mold and mildew to grow. If you notice any white, fuzzy growth on your plant, it’s time to cut back on the water. |
| Root rot | Perhaps the most serious consequence of overwatering is root rot. When the roots are constantly saturated, they can begin to decay, making it impossible for your plant to absorb water and nutrients. |
If you notice any of these signs, it’s important to take action immediately. Stop watering your plant and allow the soil to dry out for a few days before watering again. Make sure you’re using a well-draining soil and that there are enough holes in the bottom of your pot to allow excess water to drain out. It’s also important to pay attention to the size of your pot – if it’s too large for your plant, it will hold too much water and increase the risk of overwatering. Remember, less is often more when it comes to watering your cannabis plants!
Underwatering
Underwatering is a common problem that cannabis growers face. It occurs when plants do not receive enough water, and can severely impact their growth and development. It is important to recognize the signs of underwatering and take appropriate action to address the issue.
Some signs of underwatering include drooping leaves, dry soil, and curled leaves. In severe cases, the leaves may become brittle and start to turn yellow. If left untreated, underwatering can lead to stunted growth and even death of the plant.
To address underwatering, the first step is to check the soil moisture level. Stick your finger into the soil up to your second knuckle. If the soil feels dry, it is time to water your plant. However, if the soil feels moist or wet, hold off on watering for a few more days. Another method is to lift the pot – if it feels light, it may indicate that the soil is too dry.
When watering an underwatered plant, it is important to water thoroughly and slowly. This will ensure that the water reaches the roots and is absorbed properly. Be sure to check the soil moisture level again a few days after watering to ensure that the plant is receiving the appropriate amount of water.
It is also important to note that while underwatering can be harmful to your plant, overcompensating by overwatering can also cause harm. It is important to find a balance and water your plant appropriately based on its size, stage of growth, and environmental factors.
