Watering outdoor marijuana plants- How much is enough?

Updated: Dec 8, 2020

When to water potted outdoor plants:

Being a rainfed plant we must respect its optimal irrigation cycles, how does this work? The roots simply take oxygen at times when the soil is dry, which are the dry periods.

While it hydrates itself and takes nutrients at times of watering, periods of irrigation. Failure to respect these cycles can lead to the death of plants. Watering outdoor marijuana plants is crucial.

This looks very simple, but it has its technique, because when the specimens are young, small, they have a root system also of tiny size, because of this it is very possible that they do not cover more than a small percentage of the soil. For this reason, they are not able to absorb much water at an initial stage of the crop, i.e. the ability to dry the substrate is low, so every watering should last longer.

Once the plants begin to grow, their root system occupies a larger space within the substrate, this means that they will need more water to hydrate, so the ability to dry the substrate is high, consequently watering should be more frequent.

When to water outdoor plants in soil:

When the Cannabis plant is planted in soil, it has an almost unlimited amount of room for root growth, let’s say, this means that the plant itself can make a living, as well as the capillarity of the soil itself contribute to making the environment more flexible.

If the substrate is too wet and the plant drowns because it has no oxygen, it can try to expand its roots to areas of the soil that are not as wet. It also works the other way around, they can grow into wetter areas if they don’t have enough water resources where they are.

This allows certain freedoms when it comes to wrong irrigation, both under and over, although the cycles must also be respected as precisely as possible in order to improve the fruits of the plants, both in quality and quantity. Having rainfed plants with the right irrigation cycles ensures safer harvests, without the problems of fungus and disease.

Watering outdoor marijuana plants will be one your most important tasks as it is easy to over water as well. Make sure you are scheduling it correctly and not watering the plant twice as much with too many people giving it water. We did that one year and created mold inside of the 5 gallon buckets and had to throw the weed away.
