How Much Water Cannabis Plants Need?

Cannabis plants, like any other living organism, require water to survive and grow. The amount of water required by your cannabis plants will depend on various factors, including the stage of growth and the environment they are grown in. In this article, we will discuss how much water cannabis plants need and how to avoid over or under-watering.

Watering Cannabis Seedlings

Cannabis seedlings require a small amount of water initially, as their roots are not yet developed enough to absorb large quantities of water. In the first week or two after germination, you can mist the seedlings with a sprayer or use a small watering can to gently water around the perimeter of the pot. Be careful not to wet the leaves or stem, as this can lead to damping off.

Watering Cannabis in Vegetative Stage

During the vegetative stage, cannabis plants require more water than seedlings. The roots of the plant have developed enough to absorb large quantities of water, and the plant is actively growing. You should water your cannabis plants when the top inch of the soil is dry to the touch. Make sure to water thoroughly until some water runs out of the drainage holes.

Watering Cannabis in Flowering Stage

During the flowering stage, cannabis plants require less water than the vegetative stage. The plant is focusing on developing buds instead of growing leaves and stems. You should wait for the top 2 inches of soil to dry before watering your plants during this stage. Over-watering can lead to fungal growth and nutrient lockout, both of which can impact the quality of your yield.

Avoid Over-watering

Over-watering cannabis plants is one of the most common mistakes made by beginners. When you over-water your plants, you deprive the roots of oxygen and can cause root rot. Signs of over-watering include wilting, yellowing leaves, and a musty odor. To avoid over-watering, you should wait for the soil to dry out before watering again. Use a pot with drainage holes to allow excess water to escape, and make sure the soil has good drainage.

Avoid Under-watering

Under-watering your cannabis plants can be just as harmful as over-watering. When your plants don’t receive enough water, they will become stressed and wilt. The leaves may become crispy and discolored, and growth will slow down. To avoid under-watering, you should check your plants daily and water when the top inch of soil is dry. Use a moisture meter if you are unsure if your plants need watering.

Conclusion

The amount of water your cannabis plants need will depend on various factors, including the stage of growth, temperature, humidity, and the type of soil used. Over-watering or under-watering your plants can lead to various problems, so it's important to learn how to water your cannabis plants correctly. By following the tips in this article, you can ensure your plants receive the right amount of water to thrive and produce a good yield.
