What’s The Best NPK Ratio For Growing Cannabis?


Cannabis plants require many nutrients, but nitrogen, phosphorous, and potassium are the three most fundamental elements in a plant’s diet. Known by their chemical symbols N, P, and K, these three nutrients are essential for healthy growth. As cannabis plants move from the vegetative to the flowering stage, the ideal NPK ratio shifts. Meaning growers need to adapt their feeds and fertilisers.

These appear as three numbers denoting the relative concentration of each component. For instance, a ratio of 2:3:8 indicates that a product contains two parts nitrogen to every three parts phosphorous and eight parts potassium. Cannabis growers should be aware that NPK ratios always appear in this order. The value for nitrogen coming first and potassium coming last.Choosing a product with the correct NPK ratio is vital for cannabis growth. During vegetation, plants need lots of nitrogen to produce all their green parts like leaves and stems. Cannabis plants generally benefit from an NPK ratio of 3:1:1 at this point in their lifecycle, ensuring they receive plenty of nitrogen and just a little of the other two nutrients. Most high-quality soils contain plenty of nitrogen. It may not be necessary to add any of these key nutrients during the first month of growth. When growing in low-quality soils or other growing mediums, though, it’s essential to give your cannabis plants the nutrients they need. When the flowering stage begins, the NPK balance should switch in favour of phosphorous and potassium. The former helps plants produce large buds, while the latter allows flowers to increase in size. Too much nitrogen can be detrimental at this time, as it prevents flowering and can…
