  • Humboldt Nutrients Oneness 1 Gallon

    Oneness 5-9-4

    Through extensive research and development, the Humboldt Nutrients team of agronomists and chemists have created the first naturally chelated one-part formula on the market.

    Oneness (5-9-4) is Humboldt Nutrients own unique blend of plant-based amino and organic acid chelates, concentrated in a solution with complex carbohydrates, macro and micro-nutrients, metals and trace elements which are naturally found in healthy soil and vegetation.

    Oneness is the perfect solution for the beginning gardener, looking for experienced results. Formulated with over 30 proprietary natural chelates, Oneness assures that your fruits, vegetables, and herbs will receive adequate nutrition during the vegetative and flowering stages.

    This diversity of chelates protects your garden from nutrient lock-out, salt build-up, low yields, and prevents your nutrients from falling out of solution. Only when your plants requirements are fully addressed can they reach full potential.

    Oneness is 100% bio-degradable and made with chelates derived only from natural sources, setting Oneness apart from the competing synthetic chelated one-part formulas. Synthetic chelates can raise the salt-index in a biochemical system, choking out all biological activity.

    When foliar sprayed, the trademarked phosphorus booster used in Oneness makes photosynthesis in your plants function optimally, while the wide range of nutrients correct potential deficiencies.

    The Oneness Program developed by Humboldt Nutrients works excellent in re-circulating systems, aeroponics, fogponics, deep water culture and all other gardening systems.

    This diversity helps the Oneness live up to its name.

    In these uncertain times of tribulation, the world needs
    Oneness.....and so do your favorite plants.

  • Humboldt Nutrients Mayan Microzyme 1 Gallon

    NOT FOR SALE IN OREGON

    Bacterial Complex with Biological Nitrogen Fixation (BNF)

    Mayan MicroZyme is a 100% organic and ecologically safe beneficial bacterial complex with multiple species of soil microorganisms that will increase fertility while providing vital nutrients to all types of plants and crops.

    The micro-organisms present in Mayan MicroZyme (MMZ) mineralize nutrients, produce and regulate nitrogen, , build organic matter in your soil, and improve fertility and fruit yields by increasing nutrient uptake and availability.

    The micro-organisms in this concentrate are dormant with a long shelf life because of the micro-encapsulating solution.

    When the concentrate is diluted in water and aerated, the micro-encapsulation dissolves and the micro-organism populations become active and increase in number.

    DIRECTIONS:

    STEP 1: FERMENTATION
    Dilute 2 fluid ounces of Mayan MicroZyme CONCENTRATE per gallon of NON-CHLORINATED water. Add 5 Tablespoons of molasses, sugar or complex carbohydrates to mixture for every 2 ounces of concentrate. Aerate/agitate for 3 to 7 days in a bucket, compost tea brewer, or reservoir. For shorter activation time, maintain water temperature at 80 degrees.

    STEP 2: DILUTION RATES for APPLICATION
    SOIL: Add 1 gallon of Mayan MicroZyme fermented mixture (step 1) to every 30 gallons in nutrient reservoir OR undiluted fermented mixture can be sprayed directly on the soil surface immediately preceding irrigation with fertilizers.

    HYDROPONIC: Add 1 gallon of MMZ fermented mixture (step 1) to every 30 gallons of nutrient reservoir.

    HYDROPONIC EBB and FLOW SYSTEMS: Add 2 mL of straight concentrate from bottle (DO NOT DILUTE) per gallon to the reservoir in the ebb and flow system.

    FOLIAR SPRAY: Spray fermented mixture (step 1) onto the leaves until runoff occurs. Be sure spraying device is clean. Apply once a week in vegetative stage and first two weeks in bloom.

  • Humboldt Nutrients Royal Flush 1 Gallon

    A high quality crop needs a clean and effective flush to reach its full potential. By flushing your crops, you remove heavy elements and salts from the plant allowing for more aromatic and flavorful fruits and flowers.

    Humboldt Nutrients Royal Flush supercharges the flushing process by grabbing-up and binding together undesirable salts and heavy minerals. The Royal Flush then strips these larger particles out of your plant through the plant's vascular system, leaving behind sugars and strong flavors.

    It's as simple as this; imagine that your plant is composed of water, sugars and salts. If you flush out the salts and dry out the water, you're left with delicious and aromatic sugars, and sugars rule the natural world.

    Try Humboldt Nutrients Royal Flush today and experience the difference between a flush, and a Royal Flush with a clean, sweet finish.

    Royal Flush can be applied to all crops including vegetable crops, row crops, field crops, trees, vines, ornamentals, and gardens and landscaping.

  • Humboldt Nutrients Verde 2.5 Gallon

    Verde 16-1-2

    It's Spanish for green. Lush green colors and vigorous growth are what you can expect with Verde. Used as a foliar spray or as a growth catalyst for hydroponic or soil crops, Verde keeps plants healthy throughout their life cycle.

    Verde is a premium growth supplement with 16% nitrogen, 1% phosphorus, and 2% potassium, as well as calcium, iron, magnesium and other vital elements. This is a great blend for plants experiencing periods of accelerated growth.

    Some competing nutrient lines offer a (16-0-0) formula as a one-part grow fertilizer. This is wasteful and deceiving. Nitrogen alone cannot provide any plant with the proper nutrition for a healthy crop, so competing lines will have you buy separate products to supplement calcium and magnesium.

    Verde contains every element necessary for a true growth supplement, increasing the rate of chemical reactions which facilitate plant growth. Accessible nitrogen is the key to a plant having a strong and vibrant internal structure. A robust internal structure means a healthy immune system, a necessity for a plant to thrive and produce high quality crops.

    Verde is a blend that contains high quality, cold pressed Ascophyllum Nodosum seaweed, Humic acid and oure Yucca Extract. This unique product increases root, stem and stalk structure, while boosting chlorophyll levels and protecting the health of your plant.

    Use Verde in conjunction with Humboldt Nutrients base nutrients and additives for vigorous growth. This is the useful and balanced nitrogen additive you have been searching for.

  • Humboldt Nutrients ProZyme 1 Gallon *S*

    Enzymatic Concentrate ProZyme

    Enzymes are biological catalysts, derived from living organisms. Catalysts increase the speed of naturally occurring chemical reactions. Prozyme, is a concentrate, made up of over 80 different beneficial enzymes.

    Humboldt Nutrients employs the foremost experts in horticultural enzymes to formulate Prozyme into a highly diverse blend of enzymatic compounds. The result is a rich, dark biological which will break down dead root mass, starches, carbohydrates and nutrients to make them readily available and useful to the plant.

    Competing enzyme concentrates are clear in appearance, indicating low enzymatic species count.

    Prozyme is a natural chelate, or a biological key, carrying the elements necessary for plant health, and delivering them into the cell wall for maximum absorption.

    Organic and conventional nutrients can contain complex macromolecules which are harder for a plant to break down and absorb than smaller compounds. Prozyme stimulates the "pre-digestion" of these complex molecules, allowing the plant to absorb and immediately use the nutrients.

    Since each enzyme has specific role to play in catalyzing reactions, the diversity of enzymatic species in Prozyme assures that each task required by the plant is performed efficiently and rapidly.

    Whenusing Prozyme as a catalyst for chemical reactions, the rate of reaction can be over 15 million times faster than if left un-catalyzed. Without proper enzymatic activity, absorption of nutrients is sluggish and incomplete.

    Using Humboldt Nutrients Prozyme in addition to our nutrient feeding schedules will ensure that your plants maintain rapid, and complete nutrient absoprtion.

    DIRECTIONS:Add 5-10ml per gallon of water or nutrient solution.

    Humboldt nutrients ProZyme is specially developed for cleansing and treating all growing mediums.  ProZyme is compatible with all standard nutrients, rooting compounds, and fertilizing programs.
