Filum
Say goodbye to growth stalls.
Key Physiological Benefits:
Extreme Abiotic Stress Protection: Filum delivers Ascophyllum nodosum seaweed compounds rich in alginates and mannitol. These act as powerful natural elicitors and osmoprotectants, safeguarding plant cells against drought, heat, and frost shocks.
Cellular Division & Fruit Sizing: Foliar applications during fruit set stimulate cellular division, leading to larger fruit sizes, uniform shapes, and improved shelf life.
Nutrient Assimilation Support: Contains organic molecules that complex soil elements, boosting cationic exchange and improving macronutrient absorption.
Designed for maximum physiological response
Formulated with premium inputs to activate internal plant pathways and optimize harvest potential.
