Powerful Super Soil Blend of Love

As promised, here is the organic soil mix I use, along with coco coir. You must keep in mind that I allow the mixture to get hot and break down before adding it to coco coir or my plant media.

IMPORTANT: You do not want to plant your babies into this mix; you will have to cut the mixture, so it isn’t so “HOT,” or you will burn the babies and kill the plants.

The goal is to create an organic feed without having to use nutrients from a bottle. I will explain how to mix the amendments with coco coir or Organic Potting Mix in the following email.

Recipe (makes 25 gallons):
  • 2 – 1.5 cubic ft bags of high-quality organic potting soil (Pro-Mix or Roots Organic)
  • Mycorrhizae (Not needed if you buy Pro-Mix with Mycorrhizae)
  • 1 – 7lb. bag of Worm Castings
  • 1.2 lbs. Bone Meal
  • 1.2 lbs. High Phosphorus Bat Guano
  • 1.2 lbs. Blood Meal
  • 12 oz. Rock Phosphate
  • 1/4 cup Epsom Salt
  • 1/8 cup Garden Lime
  • 1/8 cup Azomite
  • 1.5 Teaspoons powdered Humic Acid

Once amended, you must let the soil mature over 6 to 10 weeks before planting.

Organic Bone Meal (3-15-0), 1.2 lbs


Organic Bone Meal will add the phosphorus and calcium needed to aid your cannabis plants. Bone meal is where you will find the help for your roots and allow the roots to thrive, growing faster when the bone meal breaks down.

Organic Bat Guano (0-7-0), 1.2 lbs


High Phosphorus – one of the finest organic fruiting fertilizers available, Bat Guano 0-7-0 can be mixed in the soil, applied as a side dressing, or, for best results, used as a tea two weeks before the bloom period of your budding plants.

Organic Blood Meal (12-0-0), 1.2 lbs


Blood meal is a great way to promote rapid growth since there is a high source of nitrogen. In addition, an excellent fertilizer for heavy feeders like cannabis helps compost piles heat up and break down fast.

Natural Rock Phosphate (0-3-0), 1.2 lbs


Natural Rock Phosphate is untreated and lasts a long time in the soil building process. Phosphate will be available within the medium, covering a wide pH range. For best availability, mix into soil or compost before planting—a superb nutrient resource for all types of plants.

Epsom Salt, 1/4 Cup


Absorbed through the roots and foliage of the plant to help the plant produce chlorophyll.

Garden Lime, ⅛ cup


Garden lime soil amendment is perfect for helping balance your pH out in the soil. I like to call it the natural buffer, and without Lime, you will see pH swings. Lime is also a calcium booster!

Organic Azomite, ⅛ cup


Azomite just sounds like some good stuff. With over 70 beneficial elements, azomite is a naturally mined volcanic mineral proven to increase yields, quality, and overall cannabis growth.

Azomite will help with your soil health, and it doesn’t take much to make this happen. Trace mineral is vital to the development of your cannabis plants, and when I see new growers and their crops, trace minerals are almost always the issue. By adding Azomite to your organic medium mix, you will notice a considerable difference in color and texture. You can find azomite in micronized powder or a granule.

BioAg Ful-Humix, 75 grams


BioAg’s is an easy-to-use humic concentrate with a low effect on bio-stimulation. Ful-Humix is an inexpensive plant and soil activator that increases cellular activities at all levels, increases the availability of nutrients, converts raw organic matter faster, and detoxifies plant cells. In addition, Ful-Humix reduces the uptake of sodium, aluminum, and other metals that negatively affect plants in the root system. Ful-Humix will also buffer the soil with organic biopolymers, thus preventing the blockage of nutrients and trace elements.

Worm Castings, 7.5 lbs


Worm castings are some excellent sh!t, literally. LOL, you need to use a small amount in or around your cannabis plants. However, the nutrients in our earthworm castings are plentiful. The significant part about worm castings is the balance of the two forms. One form can be immediately absorbed by the plant as if it were directly injected, and the other can provide nutrition that slowly feeds the plant for long periods. Building a successful organic soil mix is, in many cases, a trial and error endeavor for the homegrower. Be sure to experiment to your plant’s liking when mixing soil, and never be afraid to change things up in the process. Your crop will thank you for it in abundant yields and immaculate flavor!
