Water quality is an important aspect when growing cannabis and plays an essential role in your cannabis’ health and development. When using hydroponics to grow plants you have three options: tap water, reverse osmosis (RO) water or distilled water. For now, we will combine RO and distilled into the same category.
Using RO or distilled water in the Grobo puts your cannabis at an advantage, as these waters have no chemicals or contaminants that can harm your plant. It provides your Grobo a clean slate which allows the system to know what’s in the water and to deliver the precise amount of nutrients needed for your plant to thrive.
Compared to growing with tap water, which is not recommended as many cities treat the water with a number of chemicals to eliminate contaminants, you are introducing many of these chemicals that could harm your plant’s health and growth. For example, chlorine that is used in tap water has properties that kill off the beneficial fungi and bacteria found in plants that could stunt plant growth and reduce harvest weight. Similarly, because the baseline for your water starts at a higher concentration from the random particulates, your Grobo system is more likely to use more of the nutrients to create the perfect environment for your plant to thrive by balancing out the water. However, as a general rule, if you do not drink water from the tap, then your plants should not either—use reverse osmosis water to grow your cannabis.
