Growing cannabis or weed is picking up in many countries and many people are using different kinds of growing methods that are different from the traditional methods.

Majority of the plants need soil to grow and top soil is mostly the one that has all the nutrients that feed the plants. Other elements found in top soil are clay, organic remains and rock particles. However when it comes to growing weed, there is a lot more to consider than just the nutrients found on top soil. Some of the things that make the soil are its texture, nutrient makeup, pH level and drainage capabilities. These traits work well with almost every other plant but weed growth needs much more than these traits.

Cannabis needs soil that has richer organic elements to boost the growth. Another plant that thrives well in the same kind of soil that weed does, is the tomato. You can start the growth of your plants on the top soil but later replant them on patios or containers where they continue to grow with the help of potting soil. The soils, which are mostly ready to grow, contain nutrients that have higher benefits than those on top soil. It is very important to note that majority of potting best organic soil do not start the growth of the plants. This is because the richness of these nutrients in the soils is too much for the seedlings to grow properly.

Things to consider when buying best soil for weed

Weed growing, like many other crops needs nutrient rich soil and good drainage for better yields. Before you go out in the market, there are things you should know that would guide you into buying the right soil. Below are some of the factors.

Soil texture

Some of the most popular soil textures are clay, sand, rock particles and silt. Soil varies from place to place and from climate to climate. The best well balanced soil has 40% silt, 20% sand and 40% clay. The combination of this rich texture is called loamy soil. If there is too much clay soil, it will affect the drainage, too much silt will cause impaction, poor aeration and drainage and if there is too much sand, the soil’s moisture retention will decrease and drainage will become excessive.

To improve on the soil texture if you want your crops to grow healthy with enough water, moisture and nutrients, you should add organic matter to the spoil. If you have deficits of any soil textures, do not add the type of soil lacking without adding organic matter first for natural decomposition and less soil chemical reactivity.

Knowing the kind of soil texture you are using for your crops will guide you on what ingredients to get in order to add strength to the crop roots and the soil.

Soil composition

Testing_Soil_Composition

The ideal soil composition contains minerals, water, living organisms, air and organic material. These elements make up the soil composition and provide it with enough infrastructures for proper growth of your crops.  Minerals in the soil include calcium, carbon, nitrogen, manganese, sulphur, phosphorous and potassium. All these are essential for proper growth as they provide the soil with proteins, chlorophyll, and water regulation, the soils internal chemical processing and keeping the pH levels in check and the blockage of organic chemistry from affecting the soil.

Organic matter is another important soil composition that helps to strengthen the crops by giving them nutrients, and adding to the nitrogen levels in the soil. Organic matter, derived from decaying and dead plants and animals is very essential and without this, your weed will not grow with the strength it deserves. Other things that organic matter adds to the soil are sulphur and nitrogen, which are all vital ingredients for effective growth. Organic matter, which is also humus, gets into the soil after microorganisms break it down. Not every soil texture has enough organic matter to promote healthy growth and therefore the reason to add it to the soil.

Air is as important to crops as it is to every living thing. Crops need oxygen, nitrogen, water vapour and carbon dioxide for growth. All these are found in the soil spaces and there should be a proper balance for the crops to thrive well. In most circumstances, soil has more carbon dioxide than other gases because of the soil microorganism’s respiration.

Water, another essential soil composition acts as the solvent for plant nutrition. Without enough water, the crops will grow up looking weak and retarded. All the microorganisms in the soil also need water for survival and it is therefore important that the soil you choose for the growth of weed should have the ability to retain water in the soil.

Microorganisms include fungi, bacteria, arthropods, algae, worms, nematodes and protozoa. All these provide the soil with energy for the growth of healthy plants. There are more microorganisms living in soil than in any other place.

Ingredients

This is one of the most important factors to consider when you go buying potting soil for your weed growth. The options in the market may overwhelm you but knowing the kind of soil you are dealing with will lead you into buying soil with the right ingredients. One of the other most important factors to note is that any soil you buy should be organic. Once you establish the texture of the soil and the organic brand you want, then go ahead to check if the product contains all the right ingredients needed by both the soil and the weed.

Some of the ingredients that organic soil suitable for weed growth contains are Bat Guano, Perlite, Peat Moss, Worm Castings, Fishmeal, Compost, Plant Food, Glacier Rock Dust, Kelp, Coco Coir, Pumice, Dolomite Lime, Mycorrhizae, Vermiculite, Sandy Loam and many others. Different soils come with their own ingredients with some having all the above ingredients and more. The soils are ready to use and you can use some to start growing your crops while majority of them are too strong to act as starters. For these, you plant the crops first in the original top soil and uproot them after they sprout to plant in pots, the patio or any other container. For their continued growth, you use the potted soil, which ensures water retention stays on and the soil gets all the nutrients it needs. Majority of the potting soils are versatile and work in green houses, potted plants and in hydroponics setups.

Soil supplements

Some of the potted soils need other supplements for the continued growth of the crops. This is because some of them can only support the plants during their early growing periods. After this, you need to supplement the already existing nutrients with others specifically meant for the growth of marijuana. You can add organic fertiliser to the soil or add other ingredients lacking in the soil type you buy.

Examine the soil before purchasing

Check the label on the soil packaging says organic before purchasing to avoid buying soil with the wrong balance of nutrients. This will prevent you from buying soil with time-released chemicals that may deter with the proper growth of the crops. Feel the texture of the soil if possible to ascertain how rich it is. Good texture soil forms into a ball when squeezed and crumbles after releasing it from your hands.

This means that it is airy, fluffy and light which the soil and crops need. Also look at the color of the soil because it will also help you to decide whether it is good soil or not. Rich weed soil should be dark because it most likely has more nutrients than crumbly pale sandy soil. Pale soil could also mean that the moisture level is low which will derail proper crop growth.

Wrapping it up

The kind of soil you choose for the continued growth of your weed crop can either hinder their growth or help them to yield more. With many people choosing to grow weed indoors, it is advisable that the best option to use is grow the weed using soil. Some may choose to use hydroponics but it is more costly especially for people starting weed growing for the first time. Soil contains nutrients that make the weed flourish and all the above soil mixtures have enough nutrients to have you started.

Potting soil creates the optimal environment for proper crop growth and soil enrichment irrespective of where you are growing your crops. All you need to do with most of the potting soil is just water your plants and watch them grow. The rich ingredients in the soil do the rest and if you choose right, you will enjoy growing marijuana. So go right ahead, get the right bag of soil, and get growing your weed.
