List Of Organic Marijuana Nutrients

Organic Fertilizers/Additives For Marijuana Nutrients

Here is a list of organic nutrients that you can use in your garden:

  • Alfalfa Meal – contains 2.5 % nitrogen, 5% phosphorus and about 2% potash, a slow-release fertilizer.
  • Blood and Bone Meal – great fertilizer, though can transport Mad Cow disease and other diseases.
  • cannabis nutrients bone mealBlood (Dried or Meal) – from slaughterhouses, dried, and are ground up into a powder or meal, contains 12 – 15% nitrogen (by weight), and about 1.2% phosphorus, with under 1 % potash, apply sparingly as it is easy to burn plant foliage, can carry Mad Cow disease and other diseases.
  • Bone Meal – rich in phosphorus and nitrogen, potency based on age, fast acting, has lime that reduces acidity, can carry Mad Cow disease and other diseases.
  • Raw, Un-Steamed Bone – contains 2 – 4% nitrogen, 15 – 25% phosphorus. Fatty acids in bone retard decomposition can carry Mad Cow disease and other diseases.
  • Steamed or Cooked Bone Meal – made from fresh animal bones and boiled or steamed under pressure, powder form is readily available, contains up to 30% phosphorus, and about 1.5% nitrogen.
  • Cottonseed Meal – leftover by-product of oil extraction, it is acidic, contains about 7% nitrogen, 2.5% phosphorus and 1.5% potash, best when combined with the steamed bone meal and seaweed to be a balanced fertilizer.
  • Chicken Manure – rich in nitrogen, phosphorus, potassium and trace elements, contains up to 17% nitrogen, wet manure contains – 1.5% nitrogen, 1.5% phosphorus, 0.5% potassium, dried manure contains – 4% nitrogen, 4% phosphorus, 1.5% potassium, applied as top dressing or mixed in.
  • cannabis nutrients coffeeCoffee Grounds – acidic, encourage acetic bacteria in soil, drip-coffee is richest, contains about 2% nitrogen and traces of other nutrients, use in moderation.
  • Compost Tea – very good and full of beneficial nutrients, if Comfrey is added it adds more nutrients.
  • Cow Manure – sold as steer manure, nutrient value is low, average nutrient content is 0.6% nitrogen, 0.3% phosphorus, 0.3% potassium, with many other trace elements, apply no more than 25 – 30 pounds per square yard.
  • Diatomaceous Earth – fossilized skeletal remains of fresh and saltwater diatoms, contains trace elements, good insecticide, applied as topdressing or when cultivating.
  • Dolomite Lime – adjusts and balances pH, makes phosphate more readily available, sweetens or de-acidifies soil, contains calcium and magnesium, referred to as a secondary nutrient.
  • Feathers and Feather Meal – comes from slaughterhouses, steamed under pressure and dried, then ground up to powder contains 12 – 15% nitrogen that is slow-release.
  • Fish meal Cannabis NutrientsFish Meal – made from dried fish and grounded into powder, smells bad, not best for indoors, contains about 8% nitrogen, 7% phosphorus, and trace elements, applied when mixing or cultivating topsoil, the liquid form has less nitrogen than the meal.
  • Fish Emulsion – high in nitrogen, trace elements, some phosphorus, and potassium, difficult to over-apply, smells, some have added potash that is inorganic.
  • Goat Manure – like horse manure but more potent.
  • Granite Dust or Granite Stone Meal – contains up to 5% potash and trace elements, slow-release, not recommended indoors because it is slow acting.
  • Greensand (Glauconite) – mined from ancient sea beds with shells, contains iron-potassium silicate giving it its color, high in iron, phosphorus and 5 – 7% potash, many micro-nutrients, slow release, not recommended for indoors because it’s slow acting.
  • Guano (Bat) – from bats, powdery, rich in nitrogen, phosphorus and trace elements, water-soluble, new bat guano is high in nitrogen and can burn foliage, old bat guano is high in phosphorus, used as a top dressing or mixed in tea, do not breathe in the dust.
  • Bat Guano Cannabis NutrientsGuano (Sea Bird) – high in nitrogen and other nutrients, South American is the best, nutrient content varies.
  • Gypsum (Hydrated Calcium Sulfate) – used to lower pH, improves drainage and aeration, used to hold or slow nitrogen decomposition, seldom used indoors.
  • Hoof and Horn Meal – made from grounded horns and hoofs, excellent source of slow release nitrogen, fine horn or hoof meal is faster in releasing nitrogen, cause less issues with flies and maggots, contains 6 – 15% nitrogen, 2% phosphoric acid, applied two to three weeks before planting and remains in soil for six (6) months or more, can carry Mad Cow disease and other diseases.
  • Horse Manure – from horse stables and racetracks, composting kills weed seeds, contains 0.6% nitrogen, 0.6% phosphorus, 0.4% potassium, full of trace elements, can contain plant disease.
  • Kelp –seaweed contains 60 – 70 trace minerals that are chelated, smells like the ocean, check the label to see if they are cooked out.
  • Oyster Shells – ground and normally used as calcium for poultry, contains up to 55 percent calcium and traces of other nutrients, not practical indoors due to slow release.
  • Paper Ash – contains about 5% phosphorus, 2% potash, water-soluble, pH is high, can contain toxic inks.
  • Pigeon Manure – very high in nitrogen, difficult to find, used like chicken manure.
  • Rabbit Poop Cannabis NutrientsRabbit Manure – difficult to find, used like chicken manure.
  • Potash Rock – contains up to 8% potassium, and many trace elements, not recommended for indoors as it is slow release.
  • Rock Phosphate (Hard) – contains calcium, lime-based phosphate rock, grounded finely, contains over 30% phosphate, and many trace elements, not recommended for indoors as it is slow release.
  • Colloidal Phosphate (Powdered or Soft Phosphate) – is a natural clay, contains over 20% phosphorus, many trace elements, not recommended for indoors as it is slow release.
  • Seaweed Meal – and/or kelp meal washed, dried, and ground into meal, contains potassium (potash), trace elements, vitamins, amino acids, plant hormones, nutrient varies by brand, easily taken up by plants, helps with transplant shock.
  • Liquid Seaweed Cannabis NutrientsSeaweed (Liquid) – contains nitrogen, phosphorus, potash, trace elements, plant hormones, good for soaking seeds and clones in before planting, apply diluted solution for a quick cure of nutrient deficiencies.
  • Sheep Manure – high in nutrients, great for compost tea, contains 0.8% nitrogen, 0.5% phosphorus, 0.4% potassium and trace elements, contains little water and lots of air, heats up easily in compost piles.
  • Shrimp & Crab Wastes – contains high levels of phosphorus.
  • Sulfate of Potash – normally produced chemically, though a few are natural, contains potash.
  • Swine Manure – slow acting, wetter (more anaerobic) than cow and horse manure, contains 0.6% nitrogen, 0.6% phosphorus, 0.4% potassium, and many trace elements.
  • Wood Ashes (Hardwood) – made from woods, leaches rapidly, contains 5 – 10% potash, apply in a mix with other fertilizers at one-quarter cup per three (3) gallon pot, can cause compact, sticky soil, avoid using alkaline wood ashes, as they are above 6.5 pH.
  • Worm Casting – excreted, digested humus and other decomposing matter from worms promote soil fertility and structure, similar to coarse graphite powder in appearance, heavy and dense, high in nitrogen, never add more than 20% worm castings to any mix, any more and they can slow root growth.

Note: Nutrients in organic fertilizers may vary depending on the age, source, erosion, climate, etc. and to figure out exact nutrient contents, contact the supplier of the product.
