What is Super Soil?

Super soil is a nutrient-rich mix that’s been composted for at least 30 days. This composting process allows the soil biology to flourish, breaking down nutrients for the plant without causing a nutrient burn. A biologically active super soil mix can form the basis of a living soil recipe for autoflowers and is often used in conjunction with regenerative farming techniques.

Making Your Own Super Soil

Creating your own super soil for autoflowers involves a mix of base soil (like bagged soil) and various amendments. These amendments include worm castings, compost, perlite, and biochar. Additionally, various fertilizers like bat guano, bone meal, and rock phosphate are added to enrich the soil. This mix is then allowed to compost for at least 30 days before use.

Benefits of Using Super Soil for Autoflowers

Using super soil for autoflowers offers numerous benefits:

  1. Nutrient-Rich: Provides all the necessary nutrients for the plant’s growth.
  2. No Need for Liquid Fertilizers: Only requires watering, saving time and effort.
  3. Observation: Allows growers to focus on observing their plants and perfecting their watering technique.

The Ingredients: What Goes into Super Soil?

Super soil is a blend of organic materials that provide all the nutrients your autoflowers need. Here’s a breakdown of the essential ingredients:

  1. Base Soil: This is usually a mix of peat moss, compost, and perlite. It forms the foundation of your super soil.
  2. Worm Castings: A rich source of nutrients and beneficial microbes.
  3. Bone Meal: Provides phosphorus, essential for root and flower development.
  4. Blood Meal: A quick nitrogen source to boost vegetative growth.
  5. Fish Bone Meal: Offers a slow-release source of nitrogen, phosphorus, and calcium.
  6. Epsom Salts: Supplies magnesium and sulfur, vital for photosynthesis and plant growth.

Steps to Prepare Super Soil

  1. Mixing: Combine all the ingredients in a large container or directly on a tarp.
  2. Moistening: Add water to the mix until it’s as damp as a wrung-out sponge.
  3. Composting: Let the mixture sit for 30-60 days. This allows the ingredients to break down and the microbial life to flourish.
  4. Testing: Before using, test the pH of your super soil. Autoflowers prefer a slightly acidic soil pH of 6.2-6.5.
