House and Garden Shooting Powder for the Final Weeks of Flower
Shooting Powder is House & Garden's late-flowering additive, made to push a fresh surge of flower growth near the end of the cycle. It comes as a water-soluble powder in a sealed sachet holding 65 g. The blend is pH-balanced and built on premium-grade phosphorus and potassium. Phosphorus feeds the energy transfer that drives flower building, and it supports oil and resin production. Potassium handles water movement in the plant and helps form sugars and starches. Together they give flowers soluble PK at the stage when demand runs highest. The US guaranteed analysis is 0-0.9-0.2, listed as available phosphate and soluble potash. House & Garden states it contains no synthetic plant growth regulators and no detectable heavy metals. It works in hydro, coco and soil systems. Shooting Powder runs alongside your base nutrient rather than replacing it. House & Garden also makes Top Shooter, a liquid built from the same ingredients. The two are meant to be used one at a time, never together.
Feeding a PK Bloom Booster in the Last Three Weeks
Start three weeks before harvest, and only on healthy plants with good light, heat and CO2. First adjust the base nutrient so the solution reads an EC of 1.2. In that first week, add one sachet to every 100 liters, or 25 gallons, of feed water. For the final two weeks in hydro, raise the rate to two sachets per 100 liters. Soil growers typically stay at one sachet for those last two weeks. Dissolve the powder fully, then check and adjust pH as usual. Hold the base EC steady rather than letting it climb with the booster. Skip any other PK booster while Shooting Powder is in the tank. Too much bloom booster on top of a full base feed can stress plants late in flower. Store sealed sachets between 45 and 85°F, away from moisture. Once a sachet is open, use the contents within a year. Keep it out of reach of children and rinse off any powder that contacts skin or eyes.
