OSA Supervisor Spray

Organic 4 Life OSA SupervisorSpray is a superior, natural bio-organic leaf strengthener. Years of research preceded the unique, highly concentrated composition and revolutionary make-up of this product. Organic 4 Life OSA SupervisorSpray, is a complete carefully composed leaf fertiliser.

A biomix of natural stimulators and microelements, supplemented with Ortho-Silicic Acid (OSA). The active substances of OSA SupervisorSpray work quick and effectively, and are absorbed almost immediately by leaf and plant.

Organic 4 Life OSA SupervisorSpray ensures that leafs and plants absorb all nutrients better and more quickly, allowing them to grow better and faster. It ensures a perfect regulation for growth and flowering, thicker and firmer cell walls, and improves the natural immune system.

This allows leafs and plants to develop a high resistance against all kinds of diseases (moulds, insects, viruses, nematodes, etc. ), salt and water stress situations and other stress factors like heat and cold. Leafs and plants become healthier, develop greener and firmer leaves, and thicker and firmer stems, which are important factors for a good harvest. It improves the quality (scent, flavour and colour), yield, and lifespan.

Organic 4 Life OSA SupervisorSpray can be applied in combination with any type of liquid feed, pesticides and/or insecticides.
