Marijuana Soil Selection


After purchasing the selected seed, the next thing needed would be soil. Marijuana Soil is an essential element for plant growth. There are many considerations when purchasing soil such as the soil type,  pH, structure, and nutrient content. Knowing this information will give us a deeper understanding of the perfect soil mixtures for cannabis. There is no one best soil for cannabis, it is highly dependent on the climate and environment of the growing area. The list below is a quick guide about soil essentials to understand the best marijuana soil for cannabis.

Perfect Marijuana Soil Mix Requirements

Marijuana Soil. The best soil to be used is Loam soil. It is a mixture of clay, sand, and humus. The balance between sand and clay allows the soil to hold water but not too much. This mixture contains humus which comprises manure and organic compost. Loam can be bought at any store and is the cheapest element of your production.

Marijuana Soil PH also was known as the power of Hydrogen determines the acidity or alkalinity of the soil. Soil pH ranges from 1.0 – 14.7. A pH of 0 is considered as the most acidic while 14 is the most alkaline. A pH of 7.0 is neutral. Cannabis grown hydroponically should maintain a pH range of 5.5-6.5. When the soil becomes too acidic or basic, Calcium is added to the soil mixture to balance the pH

The 3 major nutrients your plant needs are Nitrogen, Phosphorus, and Potassium. They each play an important role depending on the growth stage of the plant.

Marijuana Soil Nutrients

Nitrogen (N) is a nutrient that plants utilize for cellular reproduction. Making it responsible for the growth of the plant stem and leaves. Plants utilize nitrogen. Vegetative plants need more Nitrogen compared to flowering plants. When purchasing soil look at the ratio between Nitrogen, Phosphorus, and Potassium. The favorable ratio would be of  20:20 20 and 12 : 12: 12. A  plant with yellow leaves would indicate a deficiency

Phosphorus (P) is another nutrient needed for photosynthesis. Phosphorus is needed during germination, seedling, and flower production. A stunted growth indicated Phosphorus deficiency. Take note of the appearance of the leaves as well. The leaves often take a dark shade of green with brown specks. A highly alkaline soil pH, greater than 7 is often the cause of such deficiency, a high alkaline content makes it difficult for the plant to absorb Potassium.

Potassium (K) is needed throughout the plant’s life. Potassium is responsible for carbohydrate synthesis and cellular growth. Potassium governs chlorophyll production and aid in keeping the stomata open which maximize the plants’ uptake of light, water, and nutrients. Potassium deficiencies include leaves that have a dull shine and the young leaves which have yellow tips that progressively turn brown.
