House & Garden Shooting Powder Pouch, 500 g

What the Shooting Powder Pouch Holds

The pouch holds 500 g of powder. Guaranteed analysis is 0 - 0.9 - 0.2, so this is a phosphorus and potassium feed rather than a nitrogen one. EDDHA-chelated iron rides along in the blend, and that is the part keeping iron available at the pH a bloom tank usually sits at. The rate works in 65 g units, with 65 g going into 100 L of solution. Expressed by weight that is 0.65 g per litre for a single dose and 1.3 g per litre for a double. A pouch this size therefore covers a little under eight single doses at that rate. The powder is water soluble and goes in alongside a base feed rather than replacing one. House and Garden names Cocos, Hydro, Aqua Flakes and soil as the base programmes it sits on top of. Run the base nutrient at reduced strength while this is in the tank, with base EC set to 1.2. It is meant for healthy plants, and not alongside a second PK product. Part number is HGSHOOTP500G with UPC 638104029858.

Dosing a PK Booster for Late Flower

A pk booster for late flower is a timing product more than it is a dosing product. The schedule puts a single dose in three weeks out from harvest, then a double dose through each of the last two weeks. Going in earlier than that pushes phosphorus and potassium at a plant still building leaf, and leaf is not what the boost is for. Weighing rather than scooping is what a bulk pack makes possible. Loose powder asks for a scale with one-gram resolution sitting next to it. Mix the base feed first, bring it to its target EC, and only then stir the powder in. Check pH after it has dissolved rather than before, because the powder moves the number. Watch EC through the week as well, since a late-flower plant drinks unevenly and a tank concentrates as it drops. Back the base nutrient down as instructed instead of adding this on top of a full-strength feed. Stacking a booster onto a full tank is how a late-flower room ends up with tip burn in the final ten days. Keep the pouch closed and dry between doses, because the powder takes up moisture from room air and cakes. A caked pouch still works, but it stops being accurate on a scale, and accuracy is the whole reason for weighing a dose.
