Understanding how your pH levels affect your plants and the importance of PH levels for your hydroponic grows is very important in the success of your final harvest. The scientific term “pH” is an abbreviation that stands for “potential of hydrogen,” which is a measure of the acidity or alkalinity of a solution. A pH of 7 is considered neutral. The pH level directly impacts how readily available a nutrient is for absorption. This means pH plays a crucial role in how successful a grow is. Regularly monitoring the pH level ensure your plants are able to get the nutrients they require. For optimal medicinal plant growth Lotus Nutrients suggests keeping the pH level between 5.5 - 6.5.
The graphic below will provide you with a visual representation of key nutrients and at what pH they are most readily available.
