Nutrients play an essential role in the cultivation of quality cannabis, helping them to grow quicker and larger than they ordinarily would. Nutrients for marijuana cultivation are specially mixed to serve specific purposes, and the ingredients have nearly infinite sources.

This has led to hundreds of nutrient companies producing their own blends of nutrients, which can be found below. Typically each nutrient line will include a set of products for the vegatative state, and another for marijuana plants in the flowering phase. These blends are carefully balanced and provide the cannabis plant with the changing preference of nutrients that it requires as it grows. In addition, there may be supplemental products available - which can include various forms of sugar (e.g. molasses) or kelp - serving different purposes to benefit your garden.

Further adding to the wide range of ingredient variation, some cannabis nutrient companies are made using an organic recipe, often appealing to medical patients among other audiences. Choosing a nutrient company and product line should be well thought out, as migrating to another company can be implications for both your plants, and your wallet.

Below you can find a list of top 100 nutrient companies, including a list of their products and recommended feeding schedules for easy reference.
