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
