Biochar helps your soil sequester more carbon and emit less nitrous oxide. Also provides a dream home for beneficial bacteria and fungi, while preventing essential nutrients from leaching away.
This top-quality compost has strong nitrogen levels and sky-high organic matter. Use as a top-dressing, mix into garden soil, or apply around the trees. Made in Sidney, Maine.
This fertilizer and amendment mix includes all the goods contained in our well-loved CannaLot MegaSoil, minus the compost and potting soil. Great for plants grown in the ground, and cheaper to ship!
NPK: 3.4-2.2-3.5. An excellent all-purpose fertilizer for those who prefer to avoid animal products. Great for flower bulbs because it won’t attract critters.
NPK: 2-5-0.2. All the NPK of fish, along with the micronutrients and growth hormones of kelp. Encourages vigorous rooting. Improves plant vigor and stress resistance, increases storage life of produce
Fulvic acid is a powerful antioxidant and chelator: one molecule can transport 60 or more minerals into plant cells for a more efficient and effective fertilization program
Molasses is a source of important nutrients, including manganese, magnesium, copper, potassium and calcium. Food grade, shelf stable. Plants and beneficial microbes have a sweet tooth, too!
Humic acids perform many complex functions. They neutralize soil pH, prevent leaching of trace minerals, stimulate growth of foliage and roots significantly, and much, much, more!
NPK: 4-4-0.5. Contains fish hydrolysate, kelp extract, humic and fulvic acids, and a dash of chilean nitrate to boost the nitrogen levels for rapid vegetative growth.
Contains about 5% potassium in very slow-release form. Can be added to the soil in large amounts without altering the pH. Greatly enhances soil structure and promotes healthier plants.
For soil: excellent source of naturally chelated elements, enzymes, and amino acids. For livestock: excellent source of iodine, vitamin A and dozens of other vitamins and trace minerals.
Magnesium is a building block of chlorophyll and therefore essential to efficient photosynthesis. May boost yields significantly, especially for roses and tomatoes.
From oyster shells, not pulverized rock. Aragonite is even lower than calcitic lime in magnesium, so it's the ideal choice for soils with excessive magnesium.
NPK: 4.6-0.9-1.3 avg. A favorite of earthworms and other beneficial soil organisms, and inhibits the growth of some notorious pathogenic soil microbes. Beloved by hemp and cannabis growers.
NPK: 6-1-3 avg. Rich in the basic nutrients, nitrogen, phosphorus and potassium, it makes an excellent fertilizer and soil additive. Can help suppress fusarium infestations.
NPK: 2.5-0.4-3.3 avg. Gives plants a noticeable boost and feeds soil organisms. Excellent vegan alternative to blood meal as a nitrogen source. Hands-down the best-smelling fertilizer out there.
NPK: 4-4-0 avg. 18% Ca avg. A macronutrient-rich byproduct of crab processing. Will help you grow massive specimens of field-grown cannabis. Improves lodging resistance and reduces branch breakage.
NPK: 13-0-0. One of the fastest release times of all organic nitrogen sources. Highly recommended for corn. The smell (understandably) freaks out deer. Use as a side-dressing or till into soil.
NPK: 0-16-0. Provides large amounts of readily available phosphorus. A most economical source of P for deficient soils. May be applied without restrictions to organically certified fields.
NPK: 7-1.5-1 avg. Effective and economical nitrogen fertilizer for Northeast soils. High levels of nitrogen and potassium are released as soybean meal breaks down, providing fertility over time.
Natural phosphorus source. Adequate phosphorus results in more vigorous early root formation, better flower and seed production, better growth in cold temperatures, and better water use efficiency.
Recommended by soil gurus Phil Callahan and Mark Fulford. Lowest concentration of heavy metals of any phosphate source. Concentrations of available phosphate were regularly over 6% when tested.
NPK: 2-2-2. 16% Chitin. Nourishes chitin-feeding bacteria and fungi, which in turn devour gnat eggs and root-feeding nematodes. Also fortifies plants’ cell walls, and fosters healthy blooms.
NPK: 0.5-0.5-0.3 apx, plus trace minerals. Worm castings limit plant disease and have beneficial effects including enhanced mycorrhizal activity and the suppression of parasitic nematodes.
A liquid combination of yeasts, actinomycetes, and bacteria. Promotes plant health and growth, and improves nutrient absorption and soil fertility. Our cannabis-growing friends can't do without it.
A granulated blend of 7 beneficial mycorrhizal fungi for mixing into soil. Add to seedbeds or work into the soil around your trees and shrubs to boost root growth, nutrient uptake and soil health.
A must-read for anyone in the cannabis industry. Covers all aspects from soil and seed, to planting, growing and maintaining, through markets and product diversification. Funny and informative.
