SM-90, Gallon

Item SMC451

Our Price: $75.99

Pin It

The organic composition of SM-90 results in it’s ability to be bio-degradable and is also non-toxic to humans, animals and plants. It can be applied as a foliar spray or directly in reservoirs with nutrient solutions. When added in small quantities directly to plant nutrient solutions, new root growth emerges. Treated plants develop greater root area, root runs and exhibit generally healthier root development.
