PowerSi Granular is the first product of its kind. A granular, slow release, top dress silicic acid. It is extremely concentrated at 26% silicic acid and 6% fulvic.
For containers under 20 gallons we recommend a dose of just 10-15 grams per plant once a month. With outdoor season approaching I want to discuss larger pot applications. When the plants are small you can start with the 10-15 gram dose. If you are in a 200 gallons pot, as the plant gets bigger so should your dosing. In a 200 gallons pot we recommend maxing out at 50 grams per container. This will cost you about $3 per month in a 200 gallons pot. This is the most economical way to apply silicic acid to your plants.
