Growing marijuana in the soil is an excellent way to grow fast, tasty buds. In fact, the soil is among the most forgiving substrates. What is the best soil for marijuana? What should you know if you want to produce your own soil? The use of the right soil is important when cultivating marijuana. Sadly it’s not always easy to find the best soil. From marijuana-specific soils to the negotiation of universal pre-fertilized and substrates types, newbies can be overwhelmed by the sheer amount of options.

Whats the Best Soil for Growing Cannabis?

Not all the best soil for marijuana cultivation and not all marijuana needs the same soil quality. Choosing the right soil depends on what sort of weed you cultivate, your environment, whether you cultivate at home or in the field, etc.

Apart from these reasons, all marijuana soils have certain common traits. Let’s check them out:

  • Texture

Marijuana likes soil texture which is light and loose. For optimal growth and health, a light texture promotes root development and ensures more oxygen reaches the roots.

  • Drainage Capacity

Cannabis soil required great drainage. It shouldn’t be pooling on top of the soil when you water your plants. When the soil has low drainage, the plants will become sick and subpar yields will result, or die.

  • Water Retainback

Water preservation is just as important as proper drainage which is the capacity of the soil to retain water. Effective marijuana soil has perfect fluid retention and drainage balance.

  • pH Value

PH is a chemical measure that reflects exactly how alkaline or acidic it is. This is important because cannabis is only doing well within a small range of pH. Strong weed soil has a pH of approximately 6.0 A pH of 5.8–6.3 is going to be perfect, but if it fluctuates too much beyond this range, yields will diminish. If the pH is seriously off your plants are going to die.

  • Nutrients

Marijuana soil requires nutrients so it can grow your plants. Fortunately, they already feature almost any soil you can purchase. But know that such nutrients often only last for 3 to 4 weeks. The nutrients in advertising soils are likely to become decimated by the time your plants begin to flower. That’s when the nutrients should start to be added.

When you expand without extra nutrients, your soil appears to cover organic materials such as compost,  hummus, guano, castings of worms, etc. Microorganisms throughout the soil can allow nutrients of these substances for your plants to use on-demand.

Characteristic of Quality Marijuana Soil

When you use store-bought potting blends those have already been efficiently “tuned” to develop. A different story if you evolve organically. Four types of natural soil come in: sandy, loamy, silky, and clay. But recognize that most soils comprise of these types of soil with varying ratios.

SANDY

Sandy soil is rough with decent drainage but lacks retention of water. Nutrients like nitrogen can also get washed away easily when drained. Sandy soil is simple to work with and is a viable marijuana grower option.

  • Rough structure
  • Less pH
  • Pros: Healthy drainage, makes the soil airy, high levels of oxygen and great to maintain with
  • Cons: Low retention of water, need regular watering

SILTY

Silty soil is a kind of medium-coarse soils, mineral-rich and chemical particles. The retention of water is strong because it has ample drainage. Silty soils were also extremely easy to use. Within it, minerals and organic substances make it one of the most fertile types of soil.

  • Medium-coarse
  • Pros: Filled nutrients and minerals, stores water well
  • Cons: Balance drainage

LOAMY

Loamy soil is a mixture of silt, sand, and clay soils with some organic matter. This is one of the better soil types for marijuana growing because it provides maximum water drainage and retention, and is rich in oxygen and nutrients.

  • Mixture of sand, silt, and clay
  • Pros: Excellent water preservation and recycling, provides high levels of nutrients and oxygen.
  • Cons: This type of soil can be expensive.

CLAY

Clay soils look like small particles of natural origin. The soil of this kind is thick and not easy to work with. It is very rich in minerals and nutrients which helps make organic growth a good option. Clay soil maintains well water but lacks drainage.

  • Good particle size
  • High pH
  • Pros: High in nutrients, stores water
  • Cons: Less drainage, compact and heavy, not easy to work with

Provisions to Enhance Quality of the Soil

If you work with natural soil, eventually it won’t be great to grow marijuana — at least not from the beginning. For example, the texture may not even be ideal, or it may have low drainage. But by incorporating additives, you can boost any kind of soil, most of which can be found in your nearest grow store.

  • COCO COIR

Coco coir was made of husks of coconut. Such thin fibers ensure excellent preservation of water and can lighten compact soils. Some cultivate their weeds using a pure cocoa substratum with special nutrients. But to modify existing soil, it’s a good way to make up to 30% coconut coir anywhere, based on your base soil composition.

  • VERMICULITE

Unlike perlite, vermiculite is a heat-treated mineral that can be used to create the soil lighter. It’s also good for water retention. While vermiculite has certain perlite characteristics, the two have different uses: use perlite to increase airiness and drainage, and use vermiculite to improve water retention. Fortunately, you can use them, since vermiculite and perlite work together well. This is useful for about 10% of vermiculite.

  • PERLITE

The most commonly used soil alteration is perlite. Perlite consists of very light, bright-white rocks, which greatly enhance soil drainage and airiness. Also, Perlite has decent retention of water. Apply 10 to 15%m perlite to change your soil with it. You may add more, but then your soil can become too thin, leaching nutrients out. Commercial soils of good quality also come with Perlite added.

  • WORM CASTINGS

Worm molds are usually seen mostly as a nutritional soil amendment, as those who involve a plethora of a lot of useful for growth. But worm molds will also enhance your soil’s drainage, texture, and water preservation. Using about 25–30% when changing your soil with worm castings.

  • NUTRIENTS

If the DIY marijuana soil is rich in organic matter, you probably won’t need to add any nutrients. However several breeders make the mistake of attaching manure and vegetable crumbs to their soil in sufficient quantity to “fertilize” it. This resulted in the soil being “too dry” for the plants which in effect hurts their growth. If you’d like to make decent use of your vegetable scraps through your garden you need to recycle them initially. 

When you think you require nutrient-based changes to your cannabis soil, you could easily buy packaged solutions customized to the growth process of a plant.
