PowerSi Bloom Silicic Acid

Power Si Bloom Runs From Flower Day One To Flush

Flower day one is the mark on the manufacturer chart, and it runs unbroken to flush. That is the entire schedule. The rate is 1 to 2 mL per gallon, or 0.25 to 0.5 mL per litre, and it does not step up by week. What separates this bottle from the Original is what rides alongside the silicon. The guaranteed analysis reads 1.00-2.00-0.5 with 0.66% soluble silicon from potassium silicate. Zinc sits at 0.3%, boron at 0.007%, and fermented Ascophyllum nodosum seaweed extract rounds it out. Growers report tighter internodal spacing, more flower sites, and ripening that finishes evenly across a canopy.

Feed Chart Rates, Mixing Sequence and the pH Question

Power Si Bloom goes into clean water before any other nutrient. The label states it does not push pH up the way an alkaline silicate does. Growers on reverse osmosis water report the opposite issue instead. Solution pH can sit low after mixing, so read it before you feed rather than after. The published chart lists no foliar rate for this bottle. Original is the one carrying a foliar instruction at 4 mL per gallon, and Bloom stays a root drench. One honest note on the silicon figure. At 0.66% soluble silicon it declares under a third of what Original does. Treat it as a flowering additive that carries silicon, not as a silicon program by itself. Most growers run the two together.

Key Features

• 1 to 2 mL per gallon, flower day one to flush: One rate covers the whole flower stage, so nothing needs recalculating week by week after the flip.
• 0.66% soluble silicon from potassium silicate: The silicon figure is declared on the guaranteed analysis, which makes it comparable against any other silicate.
• Guaranteed analysis 1.00 - 2.00 - 0.5: The phosphate is real and worth accounting for in a bloom feed rather than treating this as an inert additive.
• Fermented Ascophyllum nodosum seaweed extract: The fermented plant extract is what separates this bottle from Original, which is silicon and nutrients only.
• 0.3% zinc and 0.007% boron declared: Two micronutrients that flower-stage programs commonly run short on arrive with the additive.
• Add to clean water ahead of other nutrients: The manufacturer's mixing instruction, followed so the silicon disperses before base nutrients hit the tank.
