Growing medicinal plants means paying attention to nutrients, water, and light. Getting the balance right amongst these essential ingredients produces a bountiful harvest— right? There is one more significant factor for big beautiful flowers: pH. Adding a pH meter into your medicinal plants tool kit helps you stay on top of normal pH fluctuations in both soil-based and hydroponics systems.

Why is pH Important when Growing Medicinal Plants

Medicinal plants prefers soil, or a medium, that is slightly acidic. If the pH of the root zone, is not within the correct range, your plant will not be able to absorb the nutrients it needs to grow healthily.

If the pH of the medium is off balance, your plant will suffer with stunted growth, and nutrient deficiencies. It is crucial to ensure the medium is always within the right range, and the best way to do this is with a good reliable ph meter.

Different mediums will need a different level pH. Hydroponics and coco prefer a more acidic medium than plants grown in soil. It is important know which pH range you are aiming for, and how to keep it there.

pH in Hydro

Hydroponics is a method of growing plants, without soil. This can be growing plants in a nutrient solutions, rockool, coco, clay pellets etc.

When growing medicinal plants in hydroponic setups, it is important to make sure the pH of your feed, and the medium or reservoir, is always between, 5.8, and 6.2.

Letting the pH “swing” between these levels will allow your plant to access all of the nutrients in the medium. A medicinal plant in veg, will prefer slightly more acidic mediums than a plant in flower. But only by a little. Keep vegetating plant around 5.8 pH, and keep flowering plants within 5.8 and 6.0. As long as you are providing your plant with the correct level of nutrients, it will be happy throughout its life cycle if you keep the pH at 5.8.

Best pH Meters for Medicinal plants: Durable, Accurate, and Measure More 

For those just starting to grow medicinal plants, simple is best. Choose a pH pen that is durable, waterproof, and easy to calibrate. You don't need to get bogged down with numbers as soon as you get started. For any of the cultivators who thrive with data, invest in an option covering more than just pH. The more you know about the grow environment, the more subtle adjustments you can make, and ultimately, the better.

Here are three best PH meters:
