Power Si Granular Silica ( 0.9. 0.8. 0.8 ). Stabilized Silica Supplement. 2 kg

Power Si Granular Holds Silica Active For 30 Days Silicic acid does not stay silicic acid for long. In water it polymerises and stops being plant-available, which is why a liquid silica has to go in at every feed. Power Si Granular answers that with a stable matrix instead, releasing for up to 30 days from a single application. The guaranteed analysis is 0.9-0.8-0.8. Soluble silicon sits at 0.26%, derived from potassium silicate, with rock phosphate and ammonium sulfate making up the rest. This is a top-dress. It goes onto the medium, not into a tank. Granular Silica Top-Dress Rates By Pot Size The chart is keyed to pot volume and repeats every 30 days. A pot between 1 and 15 gallons takes 10 grams. Fifteen to 45 gallons takes 20 grams and 45 to 100 takes 30 grams. It climbs to 50 grams on a 150 to 200 gallon pot. There is a separate transplant routine. Dust each seed, dip clones after gel, and dust the hole at transplant. Fresh media is amended at one ounce per one and a half cubic feet. One honest note on the silicon figure. At 0.26% soluble silicon this is a low-concentration product. The reason to run it is the 30-day release and the dry format, not silicon per dollar. Key Features Up to 30 days from one application: The stable matrix keeps silica plant-available instead of polymerising out the way a liquid does between feeds. 0.9 - 0.8 - 0.8 guaranteed analysis: Nitrogen, phosphate and potash are all declared, so the granules can be accounted for in a feed rather than treated as inert. 0.26% soluble silicon from potassium silicate: The silicon figure is on the label, which makes it directly comparable against any liquid silicate. Top-dress rates keyed to pot size: 10 grams on a 15 gallon pot up to 50 grams on a 200, so the dose scales with the container instead of guesswork. Transplant and amending routine included: Dust seeds, dip clones after gel, dust the hole at transplant, amend at 1 oz per 1.5 cubic feet of fresh media. Derived from potassium silicate, rock phosphate and ammonium sulfate: Three named inputs on the derived-from statement rather than a proprietary blend left undescribed. Dry format, no reservoir dosing: Nothing to mix, nothing to settle in lines, and no pH correction before a feed.
