Which Water to Use on Cannabis Plants

Water is one of the most essential components required for the growth and survival of any plant. Cannabis plants are not an exception to this rule. For optimal growth and production of healthy cannabis plants, it is essential to pay attention to the type of water being used. In this article, we will discuss the types of water that can be used on cannabis plants and their relevance for growth.

Tap Water

Tap water is readily available and affordable for most people. However, tap water can contain several impurities, including chlorine, fluorine, and heavy metals. These impurities can affect the growth of cannabis plants and lead to undesirable outcomes. Chlorine, for example, can kill beneficial microorganisms in the soil, while heavy metals can accumulate in the plant tissue and cause toxicity.

Although tap water can be used for cannabis plants, it is essential to treat it before use. The easiest and cheapest way to treat tap water is by letting it sit in an open container for at least 24 hours. This allows the chlorine to evaporate, and the water to reach room temperature.

Well Water

Well water is obtained from underground aquifers and is less likely to contain impurities than tap water. However, well water can contain high levels of minerals such as calcium, magnesium, and iron, which can cause nutrient imbalances in cannabis plants. Additionally, well water can be contaminated with microorganisms such as bacteria and viruses, which can affect plant growth.

It is essential to test well water regularly to ensure that its pH and mineral content are within the acceptable range for cannabis growth. If the mineral content is too high, it is recommended to use a reverse osmosis system to remove excess minerals before use.

Distilled Water

Distilled water is water that has been purified through a process of distillation, which removes impurities and minerals. Distilled water is free of contaminants and has a neutral pH, making it an ideal water source for cannabis plants. However, distilled water lacks essential minerals required for plant growth, and its continued use can lead to nutrient deficiencies.

If using distilled water, it is essential to supplement it with a nutrient solution that contains all the necessary minerals required for plant growth. Additionally, it is recommended to alternate between distilled and tap or well water to provide a balance of nutrients and minerals to the plants.

Conclusion

The type of water used on cannabis plants can have a significant impact on their growth and development. Tap water can be used, but it must be treated to remove impurities. Well water may require testing to ensure that its mineral content does not cause nutrient imbalances. Distilled water is a safe and neutral water source, but supplemental nutrients must be provided for healthy plant growth. Ultimately, the best water source for cannabis plants is one that is free of impurities and contains all necessary minerals for optimal growth.
