best ph level for growing weed in soil

For those who have been out of chemistry class for a while, let’s start with the basics. pH, which stands for potential of Hydrogen, is an indicator of how acidic or basic a substance is. pH is measured on a 14-point scale, from zero (the most acidic) to 14 (the most basic). It’s called pH because acidic molecules contain hydrogen, which has the chemical symbol H. At their extremes, both acids and bases are caustic, meaning they react violently with organic tissue, effectively burning or dissolving it. The range of pH found in soil is much more neutral, but vitally important to cannabis production.

pH: A refresher

Now that we know the importance of soil acidity for cannabis, and how to test for pH in your soil, it’s time to learn how to correct pH. pH can be corrected by, quite simply, adding more acid or base to the soil. However, it’s not quite that easy. While any acid or base will adjust soil pH, many are toxic to plants, animals, and microorganisms. BlueSky’s pH UP and pH DOWN formulas are simply measured and added to your plant’s water before watering. It’s naturally sourced, microorganism friendly, and won’t burn plants the way harsher pH adjusters can. It’s the best choice for cannabis pH management.

Soil pH for Cannabis growth

pH. Ugh. It’s one of those finicky things pool owners and chemistry students need to worry about. You probably know that pH levels are indicators of how acidic or basic a substance is but you may not know how it affects the growth and productivity of cannabis. Not to fear! Today we’re discussing the ins and outs of soil pH, and how to ensure your cannabis crop is getting the right soil pH at the right time.

The pH scale — which ranges from zero to 14.0 — provides insight into how chemical compounds will interact with one another based on their ionic state. It is good to remember, pH reflects the concentration of hydrogen ions in a solution. More intuitively however, pH from a practical sense can be understood in terms of acids (vinegar, ammoniacal nitrogen) and alkaline bases (baking soda, potassium bicarbonate).

Testing pH is easy. Combination pH/EC meters are relatively inexpensive and require little training to use. They offer a permanent solution to disposable pH test strips and dye kits, which are cumbersome and must be subjectively interpreted by the color of the reactive test material.

Editor’s note: Balancing pH is a critical component to ensuring nutrient solubility and uptake for cannabis. As part of the upcoming release of the Fluence Cannabis Cultivation guide (available later this month), we are releasing tips on how to measure and monitor pH to ensure your fertigation strategy is not a limiting factor to your use of high-intensity LED lighting.
