Know before you buy
Azos contains the beneficial bacteria Azospirillum brasilense, which converts atmospheric nitrogen into a form your plants can easily absorb. This process provides a steady supply of nitrogen, which is essential for building strong stems and lush foliage.
Yes, Azos is fully compatible with hydroponic systems. Because it is a water-soluble powder, it can be easily mixed into your nutrient reservoir to support root health and growth.
Absolutely. Azos is a naturally occurring microbial amendment, making it a great choice for organic gardening practices where you want to avoid synthetic fertilizers.
For cuttings, you can dip the base of the cutting directly into the powder before planting, or mix it into your rooting medium. This helps stimulate root development early on, leading to a higher success rate for your clones.
Azos is a microbial amendment rather than a complete fertilizer. It works best when used alongside your existing feeding program to improve nutrient uptake efficiency and overall plant vigor.
Since Azos provides a continuous feed of nitrogen-fixing benefits, it is typically applied during transplanting or as a root drench. You can reapply it periodically throughout the vegetative stage to maintain a healthy microbial population in the root zone.
