How to make super soil for growing cannabis

Super soil for cannabis has a recipe that ensures the plants get essential nutrients, including nitrogen, potassium, and phosphorus. 

Before embarking on making the growing medium, consider the following:

• Quality of the soil will be the substrate's basis. Utilize affordable testing kits sold in garden shops. A visual check may also reveal any significant issues, e.g., if it’s too dry.

• Ground preparation. Traces of previous plants, like roots, shouldn't be present before placing the super soil.

• The best soil for growing weed outdoors is that which has an equal portion mixture of sand and silt and less clay. It also has to have good drainage.

The following tools and ingredients are also needed.

• A rake to help spread each layer of super soil ingredients
• A mixing container
• Tarp for holding the soil as it’s composting
• Bone meal, worm castings, and bat guano can go a long way towards adding to the medium’s nutritional content.
• Azomite
• Dolomite

Once you have the items, use the following steps

1. Spread soil on the tarp

2. Add bone meal and mix it up with the soil.

3. Add azomite and dolomite to the mixture. Then add another layer of soil on top.

4. Add worm casting into the pile and put another layer of soil on top.

5. Add the bat guano to the pile, then have another layer of soil on top of the mixture.

6. Over the next week, mix the soil with the ingredients once daily.

Once you have acquired an even blend, you’re halfway there. Next, is the compost making process, which requires patience. Here’s how to go about it:

1. Store the super soil mix in a tarp and close it up. The soil needs to retain its water content. A cultivator should ensure the soil isn’t too wet or too dry, just moist. A dry mixture will halt the composting process.

2. Over the next two months, expose the covered soil to the sun. The heat, combined with the microorganisms, breaks down the nutrients. Add worms to the mixture to help in aeration. It’ll accelerate the process.

3. After one or two months, your super soil for weed cultivation will be ready.

2. The next step is to provide the right amount of water for your cannabis plant, every two to three days. One way of checking if your crops need water is by dipping your finger two inches into the soil. If wet, don't water, but if dry, hydrate them.

3. Watch the weed plants grow through their phases until they bud.

During harvest, experience the ‘super’ in the soil. The cannabis plants offer decent yields and produce quality THC full buds.

It also saves money as it’s cheap to prepare. Super soil is also environmentally friendly. When preparing and cultivating weed using the soil, you don’t release any harmful chemicals into the environment.
