Marijuana Soil Selection

After purchasing the selected  seed, the next thing needed would be soil. 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. The list below is a quick guide  about soil essentials.

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 of  manure and organic compost . Loam  can  be bought at any store and is the cheapest element  of your production.

PH also 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 .

Nitrogen (N) is a nutrient which 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 which have a dull shine and the young leaves which  have yellow tips which progressively turn brown.
