A Guide to the Best Cannabis Nutrients

Knowing the best growing medium for cannabis plants is important for cultivating. Getting the most from your plants requires some knowledge of the specific nutrients cannabis needs to grow.

The following nutrients are found in SoHum Living Soils, a fully amended potting mix, inspired by True Living Organics.

Feather Meal

Feather meal is a natural, organic fertilizer. It is perfect for plants that require a lot of nitrogen to thrive, as it rapidly releases nitrogen early on to stimulate growth. Feather meal also has a slow release quality to it, leading to healthy late-stage growth. Nitrogen helps to stimulate photosynthesis, leading to strong leaf growth and a healthy shade normally associated with high-quality products.


Langbeinite is a unique type of crystalline. It is only found in a few locations across the globe, with the main source coming from New Mexico. Each batch is cleaned before sold for commercial use. We ensure that we only use the best nutrients for growing cannabis, so you can trust that all langbeinite used in our soil has been thoroughly prepared first. Langbeinite is highly effective, as only a few granules of the substance can lead to high nutrient levels in the soil.


Kelp has a ton of nutrients and minerals that make it an ideal addition to any living soil. Dried kelp has a high concentration of potassium, along with 70 other minerals, amino acids, and other elements important for plant growth. It also contains mannitol, which helps plant cells process sugar faster and easier, stimulating growth. We only use high-quality Norwegian Kelp in our soil to give you the best possible results.

Crab Meal

Crab meal helps to make your soil incredibly healthy and is another one of the greatest nutrients for growing cannabis in soil. It has chitin, which contains nitrogen, calcium, and magnesium. Taken together, these elements promote healthy plant growth over an extended period. If you are growing your plants outdoors, crab meal ensures that ants, grubs, slugs, and snails stay away from your crop. This nutrient has also been shown to ward off weeds.

Bone Meal

Bone meal is an organic fertilizer that is high in phosphorus, proteins, and calcium. These minerals are slowly released over time, making bone meal an excellent way to promote healthy growth over the lifetime of the plant. Phosphorus is especially important to plants when they are rooting and just before they begin to flower.

Alfalfa Meal

As with other nutrients, alfalfa meal contains nitrogen, phosphorus, and potassium. It also contains magnesium, sulfur, and triacontanol. Triacontanol is one of the best growth hormones for plants. It’s perfect for indoor and outdoor growers, as only a small amount is needed to fully enrich the soil. The alfalfa meal added to SoHum Living Soil is properly fermented and just the right amount.


Derived from obsidian, perlite is mined and subsequently heated to create small, round balls. It is primarily made up of silicon and lacks the same type of nutritional content as other key ingredients. However, it helps stimulate root growth by encouraging water retention in the roots. Perlite is ideal for use with indoor and outdoor gardens and is perfect for those who are growing in small spaces.

Peat Moss

Peat moss is probably the best-known soil nutrient, as it is a staple across North America. It is ideal for plant growth as it does not have any disease or insect development. Peat moss can hold more than 20 times its weight in water, which makes it perfect for those wanting to start growing seeds

Worm castings

Worm castings are earthworm waste, containing a lot of rich soil. This component is rich in calcium, which is essential for your plant’s healthy growth. These castings are great for indoor and outdoor gardeners, as they help with nutrient absorption and prevent pH imbalances in the soil.

Whether you are growing cannabis professionally or for personal use, you need to be sure that the soil you choose meets all those nutritional requirements. Using SoHum Living Soils is the perfect solution. Our soil has been scientifically engineered to include every nutritional requirement your cannabis plants need to thrive. SoHum Living Soil is suitable for its entire life cycle, taking a lot of guesswork out of cultivating.
