Biodiversity is the key when it comes to building a proper organic medium. Soil life thrives on diversity. That being said, there are a few things to keep in mind with building a soil that caters to growing cannabis.
Key Ingredients to Make Super Soil
1. Begin With Your Base Mix or Amended Organic Soil
To make a successful super soil, you can either start with a pre-made potting mix or make a simple amended organic soil by dividing your favorite compost, base (eg. peat moss, coco coir), and aerator (eg. perlite, vermiculite) into equal parts and mixing them together to form your initial starting point.
2. Establish a Fungal Population
Fungi love to develop mycorrhizal relationships with root systems (or rhizosphere), and providing food for them to thrive will help facilitate these tiny little symbiotic friendships. Think Kelp meal, Humic acid, Mycorrhizal inoculant.
3. Establish a Bacterial Population
Just as important as fungi, bacterial populations can help break down complex sugars and convert them to readily available macro and micronutrients for your cannabis. They also help to establish and maintain the immune system of your plants, making them more adept to fight off pests, diseases, and inclement environmental conditions. Use ingredients like Microbial inoculant, Vermicompost, Bat Guano.
4. Fortify With Micro and Macronutrient Sources
Cannabis, like any other plant, requires a regiment of micro and macronutrients to thrive. In many case, these nutrients are often provided via plant fertilizers. However, with organic super soils they’re instead amended into the base mix to be released and/or broken down into food for your plants over time. Use fertilizers with Nitrogen, Phosphorus, Potassium, magnesium and calcium.
