Additive : General Hydroponics Rare Earth 4 lb

Rare Earth is a rich blend of silicon, humates and 72 rare minerals. Blend it with rooting media, top dress around the plant stem or add it directly to a nutrient solution to develop a protective silicon shield. Silica naturally improves plant resistance to heat and nutritional stresses, deters fungal diseases and reduces insect damage resulting in stronger development and denser, heavier fruit.
