Although cannabis has unique, intriguing properties, it is the same as any other plant. The species grows better in optimal conditions, with a specific amount of water and sunlight.
For the plant to thrive and develop properly, it will need several nutrients. Although you can get these substances from things such as wood ashes and compost, most growers prefer utilizing specialized cannabis products.
In this article, we will review the best plant food for cannabis and compare their features.
What is the importance of fertilizer?
While you can utilize every part of the plant, cannabis growers always focus on buds. They are full of cannabinoid chemicals that carry psychoactive but also healing properties. By using the right fertilizer, you can ensure that plants have healthy buds.
Fertilizers are also important as they affect their quality. Healthy, strong plants have much better-tasting buds. So, if you’re growing cannabis commercially, this will make it easier to have a good harvest and predict profits.
Which nutrients do you need for cannabis?
Cannabis heavily depends on nitrogen, phosphorus, and potassium, a trio we often refer to as NPK. Depending on the stage of development, the plant will require different proportions of these chemicals. So, during the growth stage, it will need a 3:1:1 NPK ratio. The flowering stage requires a 1:3:2 ratio, and during late flowering, you will have to put the 0:3:3 mixture into the ground.
Although the emphasis is on these three substances, cannabis benefits from other matters, as well. It needs lots of secondary and trace nutrients on top of NPK. Important secondary substances are calcium, magnesium, and sulfur, while tertiary chemicals include silicon, cobalt, manganese, iron, zinc, and boron.
Besides these nutrients, cannabis also requires oxygen and carbon dioxide, which they get from air and water.
