RSA (Rapid Silicic Acid) is the 8th-Generation Elite Series stabilized silicic acid formula from Advanced Nutrients — engineered to build rock-solid stems and thick stalks so your plants can hold up the weight they deserve.

The future of silicon for commercial cultivation. Stabilized mono silicic acid — the most bioavailable form of silicon — delivers stronger stems and thicker stalks, preventing bending or breakage under heavy, high-yield buds. Say goodbye to stretch and hello to rock-solid structure.

Why growers run RSA:

• Stabilized mono silicic acid — the most bioavailable form of silicon
• Strengthens stems and thickens stalks
• Prevents bending and breakage under heavy bud weight
• Reduces stretch and improves overall plant structure
• Compatible with all hydroponic media
