Hydroponic Cannabis Cultivation
All you Need to Know
A stable pH is one of the secrets to the vigorous growth of cannabis, and its sudden change may cause great problems for plants. Stress due to pH changes, temporary stop of growth are the least of the possible difficulties. The ability of hemp to absorb necessary elements depends on the acidity of the substrate or nutrient solution. Both low and high pH leads to a lack of certain minerals. Fertilizing the soil will not solve the problem. Macro and microelements will accumulate in soil or water, but the roots will not be able to absorb them. What are the optimal pH values for cannabis? Read our new research results below.
If you want to achieve high yields by providing optimal conditions for plant development, it is important to not only give the best nutrients for hydroponic cannabis but also to regularly check the pH level of your medium. Proper care involves not only regular watering and feeding but also controlling the acidity of the environment. It is determined by the activity of positive hydrogen ions. It is enough to know that the pH indicator reflects the ratio of alkaline and acidic impurities in a liquid. There is a scale from 1 to 14, where 7.0 is neutral. From 1 to 6.9 units – the liquid is considered acidic, from 7.1 to 14 – alkaline.
