Plants need to eat, and the cannabis plant is one hungry plant. As growers, this means providing a constant supply of a complete blend of all the micro and macronutrients cannabis needs to thrive. Nutrient companies have done most of the heavy lifting by formulating unique blends to ensure cannabis plants have everything they need as they mature through the different growing stages.

Cannabis nutrients typically come in three parts: one high in nitrogen, one balanced with nitrogen and phosphorus, and one heavy in phosphorus. In addition to these bases, companies provide different boosters to help add critical nutrients for the plant’s growth stage. Typically, cultivators can choose between concentrated bottles and bulk salts or powders.

Concentrates are mixed directly into stock tanks based on the manufacturer’s recommendations. It is important to follow mixing instructions to prevent cannabis nutrients from falling out of the solution. Bulk salts and powders must be premixed to ensure complete dissolution before they’re added to stock tanks. In most cases, nutrient companies have special blends to match every growing medium, including soil, coco, and hydro.
