RAW Potassium 0-0-50 is a fully soluble powder supplying 50 percent water soluble potash derived from potassium sulfate. It runs at a sixteenth to an eighth of a teaspoon per gallon in the reservoir. That is why an 8 oz tub stretches to roughly 800 gallons of feed.

Why RAW Potassium 0-0-50 Is Dosed So Lightly

Concentration is the whole point of a single-element powder. Fifty percent of this tub is water soluble potash derived from potassium sulfate. NPK Industries describe it as fully soluble, with nothing left sitting in the bottom of the tank. Nitrogen and phosphorus are both zero, so nothing else moves when you add it. The rate reflects that strength: a sixteenth to an eighth of a teaspoon per gallon in the reservoir. A 2 oz pack makes 200 gallons, which scales to somewhere near 800 gallons for the 8 oz size. The tub itself weighs half a pound. It sits alongside any feeding programme rather than replacing part of one. That is the usual reason a grower reaches for a straight salt instead of a blend.

When a High Potassium Fertilizer Earns Its Place

Two situations justify keeping one of these on a shelf. The first is a deficiency that shows up mid-flower. A heavy fruit load draws potassium down faster than a base feed replaces it, and older leaves start to go at the margins. The second is recipe work, where a grower building a custom solution needs to move one element without dragging nitrogen or phosphate along with it. That precision is the argument for a single salt over a bloom booster. Measure by weight rather than by spoon if the tank matters, because a scoop of powder varies more than people expect. Add it to water that is already moving, let it dissolve fully, then set pH. Two honest limits are worth stating. Sulfate comes along with the potassium and adds to the solution strength. A deficiency that is really a pH lockout will not respond to more potassium at all. Check the runoff reading before reaching for this.
