Mykos is very-specific specie of Mycorrhiza that works faster and stronger. If you haven't heard of mycorrhiza, it's a microbe that builds root mass and increases plant uptake of nutrients and water. With more roots, you get more fruits. Mykos grows the biggest and best fruits, vegetables, flowers, and herb! It also helps 'leap start' new transplants and shield roots from shock and disease. Mykos is a beneficial additive; it may be used with any nutrient line. Great for vegetables, fruits, & herb.Azos is a beneficial microbe that sparks new root development and boosts growth. Azos works by rapidly increasing plant production of IAA (indole-3 acetic acid) a natural plant hormone, affecting cell division, growth rates, plant and root development. Azos enhances growth by converting atmospheric nitrogen into a usable form available to plant roots. Use Azos to quickly and naturally root new cuttings; add to transplant to kick-start new development and add to hydroponic reservoirs to feed and fuel abundant growth. May be used with any nutrient line.
