Product Description


AZOS is a beneficial bacteria that promotes plant growth naturally by fixing atmospheric Nitrogen and converting it to a plant available nutrient. The supplemental source of nitrogen increases the plant's ability to quickly establish roots for faster vegetative growth.


Apply around the root zone of plants. Apply weekly through vegetative and early flower stages. 


AZOS works in all types of growing media and can be used in combination with synthetic and natural fertilizers. Great for Vegetables, Fruits, Herbs & Flowers.

Growth Promoting Bacteria

Nitrogen-Fixing Bacteria - Of all the nutrients transported to plants through the soil, nitrogen is required in the greatest amount. It drives chlorophyll production in the foliage and keeps plants green and efficient. It is a fundamental part of amino acids and other compounds that assure crop health and productivity. It is a major part of every protein molecule and soils are often deficient in this element. However, the atmosphere is comprised of around 80% nitrogen which is in a form (N2 or Atmospheric Nitrogen) that is not conventionally available to plants. 

Nitrogen From the Air - Somewhere along with the evolutionary development of the "Plant - Soil - Microbial Matrix", certain bacteria began to specialize in tasks to enhance plant growth, which in return provided the microbes with a food source exchange opportunity. A select group of bacteria classified as "Diazotrophs" began to supply nitrogen to plants from a range of sources, including decomposed plant litter, dead micro-organisms, and sequestration of atmospheric nitrogen. Azos belongs to the last of these groups and functions primarily as an atmospheric nitrogen converter. 


A Natural Isolate From the Amazon - Azos is a particularly-efficient agent originally isolated in the Amazon Basin where the lack of soil, the rapid breakdown of any vegetation by hungry microbes, and the environmental conditions which require "Growth to Survive" is a fundamental proposition of the ecosystem. AZOS specializes in the highly-efficient conversion of the N2 form of nitrogen into plant-available ammoniacal nitrogen. 


Plant Growth Promoter - With the increased accessibility of nitrogen in the soil, AZOS can catalyze a natural growth hormone within plants that help promote more root and vegetative growth. AZOS is excellent for rooting out cuttings, transplants, and water-borne applications throughout various plant stages.

AZOS Red Liquid Application:

Propagation Stages

1. Dipping/soaking cuttings – Add 20ml per gallon of water. Dip or soak cutting tips for at least 15 seconds before transferring to rooting media or machines.

2. Soak grow plugs/rockwool cubes – Add 20ml per gallon of water. Soak grow plugs/rockwool cubes for 10 minutes.



Propagation machines (EZ Clone, Turbo Cloner) 

1. Adjust the pH of the water to 5.5-6.0.

2. Add 5ml per gallon of water.

General Watering

In reservoirs or hand-watering – Add 5mL per gallon of water. Watering a minimum of 1/4 gallon - 1/3 gallon per potted plant. 

Raised beds – Add 5ml per gallon of mix and water in regularly every 1-2 weeks during vegetative stages.

May be mixed with other organic fertilizers or plant bio-stimulants.


May be applied by overhead or drip irrigation at the recommended rate of 16 ounces per acre.

Dosing machines & Nutrient Delivery Systems

Add 3.75 gallons to of AZOS Red Liquid to 1.25 gallons of water in order to create a concentrate. The concentrate is then applied through 2000 gallons of water.

Hydroponic Application

Add 5ml per gallon of water in reservoirs through veg/grow.
