How Important is Micro in Your 3-part Base Nutrient Formula?

In a word, very.

The majority of 3-part base nutrients in the market, often referred to as grow micro bloom, have Micro as a vital, yet often underappreciated component. Therefore, it’s important for a grower to understand the role of Micro in the feeding program and to choose the best one for cultivating their high-value crops.

Micro provides a rich mix of trace elements along with many chelated micronutrients that can be absorbed by plant cells more readily, pacing the growth phase.

Let’s dig deep into the components that impart Micro it’s typical traits.

Calcium Nitrate

Calcium is an integral part of plant cell wall and gives strength to binding and linking molecules together. Calcium participates in metabolic activities within the cells and mediates intracellular communications. In the absence of a balanced source of Calcium, metabolism in plants cell either slows down or stops altogether. Calcium Nitrate is the ideal inorganic N fertilizer source and used when Calcium and Nitrogen are required to be supplied at the same time.

  • Retains Magnesium and Phosphorous in plants
  • Increases quality of crops
  • Calcium deficiency leads to stress
  • Improves function of antioxidants
  • Protects plant cell from biochemical stress
  • Nitrate is reduced to Ammonium (Nitrogen source) and essential for Ammino acid, protein, DNA, RNA, ATP and hormones

Ammonium Nitrate

A common Nitrogen source as it contains both Nitrogen and Ammonium. It is less concentrated than urea but is more stable without loss of Nitrogen in the atmosphere.

  • Ammonium is said to increases the vegetative growth in plants
  • Augment Calcium, Potassium and Phosphorous uptake
  • Effects the chemical composition of the whole plant
  • Influence enzyme activity

Potassium Nitrate

An exclusive source of Potassium and Nitrogen for optimal plant nutrition. The salt is absorbed efficiently and is free of chloride. The optimum level of potassium improves quality and overall yield, and Nitrates enhances formation of organic acid.

  • Mediates opening of flowers
  • Increased leaf area duration
  • An optimum level leads to increase in the concentration of sugar, glutamic acid, aspartic acid and alanine
  • Improves the taste and aroma of fruits
  • Resistance towards stress
  • Increases chlorophyll concentration
  • Improves tolerance towards drought and frost
  • Plays a crucial role in development of flowers

 Urea

Urea is basically a Nitrogen release fertilizer and has the highest Nitrogen content of most of the nitrogenous fertilizer available in the market.

  • An important source of Nitrogen
  • Retards aging in plants
  • Increases tolerance to freezing

 Cobalt Nitrate

Cobalt is an essential component of quite a few enzymes and co-enzymes. It forms complexes on interaction with other elements.

  • Essential for plant growth
  • Enhances stem elongation
  • Increases plant height
  • Increases number of branches and leaves
  • Retardation of senescence of leaves

Iron EDTA

Micronutrients are essential in all stages of plant development.  However, they are not absorbed directly and are transported in a chelated form. EDTA is a chelating agent, and Chelation is a process wherein the nutrient moiety is bound to an organic molecule like amino acid or proteins so that it is quickly absorbed by plants and last longer in the medium. EDTA enhances budding and flowering and draws excess mineral nutrient out of solution. It also boosts phytoextraction of heavy metals.

  • Without Iron plants cannot produce chlorophyll, no oxygen, and no green appearance.
  • Mediate enzymatic activity

Copper EDTA

  • Copper is essential for growth during seedling stage and prevents malformed head
  • Imperative in flower bud initiation
  • Vital role in photosynthesis
  • Essential for carbohydrate and protein metabolism
  • Adds color and flavor

Magnesium EDTA

  • Acts and co-factor in activating enzymes for biosynthesis of aromatic amino acid
  • Promotes stem elongation
  • Mediates apical development
  • Prevents stunted leaf growth
  • Improves fruit quality

Zinc EDTA

  • Zinc mediates pollen function and fertilization
  • Zinc deficiency decreases thickness of leaves
  • Zinc deficiency reduces leaf chlorophyll concentrations
  • Plants have stunted growth in absence of Zinc

Sodium Borate

  • Boron is essential for plant growth
  • Boron deficiency leads to reduced fruit quality
  • Boron application improves calcium mobility
  • Develops pollen energy

Look for these important components in your 3-part base nutrient formula and get the most out of your grow room in the next crop cycle.

    Why isn’t Micro listed in the 3 part feeding chart?????????????????????????????

    I would have been using it all along. Now entering 4th week of cannabis flower
