Super Soil Recipe – Grow All Organic – Just plant and add water!

Super Soil creatorThis Super Soil recipe was developed by a legendary underground grower by the name of Subcool. One of the world’s foremost cannabis aficionados subcool has pioneered and shared his growing experience with thousands of other growers around the world.


Below is a how-to guide for mixing your very own batch of organically fertilized Super Soil. Once mixed just add water and the soil will nurture your plants from seed all the way to harvest. Giving you the best chance at smoking those dank resinous buds you see in the centerfold of High Times magazine.



Buds grown with this method finish with a fade and a smoother, fruitier flavor. The plants aren’t green at harvest time, but rather purple, red, orange, even black—plus the resin content is heavier, and the terpenes always seem more pungent. This method is now being used by medical growers all over the world, and with amazing results.




Subcool’s Organic Super Soil Recipe | Mixes 8 -10 gallons



In a large plastic tub (50-70 Gal.) mix all the ingredients below. Make sure to mix well with a hand spade (trowel) and or hand cultivator. Add about three to six cups of water and eight cups of perlite (optional) to the soil and mix again to activate microbial activity. Once all the mixing is finished let the soil sit for thirty days after which time the super soil will be ready to use.

  • One Bag of  high-quality organic potting soil – (8 – 10 gal.) This is the base of your mix. Which soil you select is very important. Its would wise not to skimp here buy buying something cheap like Miracle Grow. Try to make sure no (or as few as possible) chemical additives are in the soil. Check and make sure the soil contains coco -fibre and mycorrhizae. 
  • 3.125 to 6.25 lbs of Organic Worm Castings. Castings added to the soil carry to the root zone a rich compliment of soluble plant nutrients and growth enhancing compounds, a diverse and populous consortium of microbial life and a substrate of organic matter harboring a storehouse of nutrients that are not lost to rain and irrigation.
  • .625 lbs or 5/8 lbs or 10 ounces Steamed Bone MealAn excellent all-natural slow acting organic fertilizer that helps develop sturdy root systems and stimulates growth.
  • .625 lbs or 5/8 lbs or 10 ounces Bat GuanoBat guano provides a high concentration of nutrients to plants and the surrounding soil while improving drainage and texture. Bat guano is a suitable fertilizer for plants and lawns, making them healthy and green. 
  • .625 lbs or 5/8 lbs or 10 ounces Blood Meal. Used for nitrogen hungry plants with nitrogen constituted from bloods high protein content. These blood proteins are rapidly broken down by soil bacteria into ammonia fostering inside the soil warm moist conditions that favour beneficial bacterial growth. 
  • 3/8 lbs or 6 ounces Rock Phosphate.  One of the three main nutrients plants require to thrive is Phosphorus. It functions as one of the major players in the process of photosynthesis, nutrient transport, and energy transfer. Phosphorus also effects the plant’s structure at a cellular level. A plant with the proper amount of phosphorus available to it will grow more vigorously and mature earlier than plants with inadequate phosphorus. A plant with phosphors deficiency will exhibit stunted growth, lack of fruit or flowers. 
  • 3/32 cup or 1.5 tablespoons Epsom Salts. Can stimulate plant growth by boosting the plant’s internal circulation. Enriches the soil before you plant.
  • 3/4 teaspoon powdered Humic Acid. Increase root vitality. Improves nutrient uptake. Increased chlorophyll synthesis. Better seed germination. Increased fer tilizer retention. Stimulates beneficial microbial activity. Healthier plants and improved yields.
