Have you just planted your first cannabis plants in the ground? Now the big question is: how often do I need to water my cannabis plants? This seemingly simple task can actually make or break the health of your plants. In fact, over-watering is far more common and often more damaging to your green friends than under-watering.
In this article, you will learn how to provide your hemp plants with the optimum amount of water so that they thrive.
1. how often should I water my cannabis?
The frequency of watering cannabis depends on several factors:
- Composition of the soil: Well-drained soil dries out more quickly and requires more frequent watering, while heavier soils stay moist for longer. Which soil is right for your seeds you can find out here: The right soil for growing cannabis.
- Average daily temperature: Higher temperatures lead to more evaporation and therefore more frequent watering.
- Climate: You need to water more frequently in dry weather than in humid weather.
- Cultivation method: Plants in containers dry out more quickly than those growing directly in the soil.
NoteMany growers achieve good results by keeping an eye on the moisture content of the soil. As soon as the top 2-3 cm are dry ("finger test"), it is time to water the plant again. Depending on the soil, climatic conditions and the type of cultivation, this may mean that you need to water your plants daily or only every few days.
2. when should I water my cannabis? (morning / evening)
In general, there are two preferred times when you should water your cannabis plants:
- In the morning: If you water your plants before sunrise, they can absorb the water better and use it throughout the day. This helps to prevent waterlogging and keep the roots healthy as the water evaporates during the day.
- In the evening: Watering late after sunset reduces evaporation and ensures that the plants are well supplied with moisture overnight. This can be particularly beneficial during hot periods, as the water stays in the soil longer and the plants are well supplied overnight.
3. how can I recognize that my plants are thirsty?
You can tell by these signs that your cannabis plants are thirsty:
- Flabby, weak plants: The plant loses its firmness and hangs limply.
- Dry, brittle leaves: The leaves do not turn yellow or brown, as many people think, but dry and brittle and lose their flexibility.
- Dry soil: The soil is also dry below 2-3 cm.
4. how should I water my cannabis plants?
The golden rule is: keep the soil moist, but avoid waterlogging it. Here are a few tips for the different growth phases:
- For seeds: In the beginning the seeds need seeds little water to prevent them from drowning. Therefore, start with a light spray to keep the soil moist.
- For young plants: Care should be taken when the plants are growing. Use a sprinkler to gently water the young plants and protect their roots from too much moisture.you can also apply this to our cuttings cuttings.
- Growth phase: Check regularly with your finger whether the top 2-3 cm layer of soil is dry. If so, it's time to water.
- In the flowering phase: Keep to the same principle. Allow the soil to dry on top and then water thoroughly so that the substrate absorbs about 30% of the pot capacity. This promotes healthy root growth.
