Pure Professional Max Air

Pure Professional Max Air is Simply Organic’s most aerated substrate, designed for maximum airflow and drainage in high-performance cultivation setups. This ultra-light, peat-free blend is made with a boosted ratio of large coco fibers and coarse perlite that creates an open matrix allowing oxygen to move freely through the root zone. This results in faster root development and enhanced nutrient uptake, while reducing the risk of overwatering or root-bound stress — making it especially beneficial for fast-growing or high-yielding strains. Free from synthetic additives and unbuffered, you have full control over feeding and fertigation strategies. If you're looking for a slightly less porous option with similar structure, check out Pure Professional Air for excellent aeration and a bit more water retention. For a clean and simple base to build your own custom blend, Pure Basic is a solid choice.
