Essential Information for Cultivators
Advanced Nutrients RSA™ (Rapid Silicic Acid) is a revolutionary 8th-generation silica supplement for plants. Unlike standard silica products, RSA features stabilized monosilicic acid—the only silicic acid for plants that they can immediately metabolize. It revolutionizes our previous Rhino Skin formula, utilizing 27 years of cannabis research to provide a more effective solution.
RSA acts as “silica armor” for your crops. Key benefits include:
The integration is effortless. Add 0.5 mL per gallon (0.13 mL per liter) to your nutrient solution.
Add RSA to your reservoir first, and allow it to fully mix before adding your base nutrients or other products. This ensures optimal integration and prevents compatibility issues.
You should apply RSA once per week, all weeks of both the Grow (Vegetative) and Bloom (Flowering) phases.
Yes. RSA is specially designed for use with all hydroponic growing media, including coco coir. It is also compatible with continuous liquid-feed growing systems such as aeroponics, drip irrigation, NFT, flood and drain, and deep water culture.
RSA packs a high concentration of silica derived from stabilized monosilicic acid. The guaranteed analysis lists Soluble Silicon (Si) at 13%
No. RSA’s stabilized monosilicic acid formulation stays in solution and won’t polymerize in your reservoir. Unlike some potassium silicate products that can cause buildup, RSA maintains clean delivery through drip systems, filters, and irrigation lines.
Results can appear within 7-14 days of consistent application. The earlier you start RSA in vegetative growth, the more pronounced the structural benefits.
Yes. RSA’s stabilized monosilicic acid formulation is compatible with biological inoculants. The stabilized monosilicic acid formulation supports microbial populations without disruption, making it ideal for growers running biological inoculants like Voodoo Juice® Plus.
Yes. Like all Advanced Nutrients products, RSA is backed by our 100% Money-Back Grower Guarantee. If you are not thrilled with the results, you can return the unused portion with your original sales receipt to the place of purchase within six months for a full refund.
