King Solomon Dry Fertilizer Calculator: Size Stock Tanks, Injection Rates, and Bag Counts
Editorial · Order Junky
A free calculator for King Solomon's two-part dry fertilizer. Enter your batch and program to get Veg A&B and Bloom A&B stock-tank recipes, injection rates, and exact 50 lb bag counts—then order the bags in one click.
Executive summary: King Solomon is a commercial two-part dry fertilizer (Veg A&B, Bloom A&B) made by PlantGeek and now stocked on Order Junky. Dry salts are cheaper per gallon fed than premixed liquids, but they force a question liquids don't: how much powder goes into which stock tank, at what injection ratio, to hit my target EC? The King Solomon Dry Fertilizer Calculator answers that in seconds—stock-tank recipes, injection rates, and 50 lb bag counts for hydroponic and soil programs—so you buy the right number of bags instead of guessing.
Direct answer: what the calculator does
Enter your batch volume and program stage (veg or bloom) and it returns:
- Stock-tank recipe — how much Veg A, Veg B, Bloom A, and Bloom B to dissolve per stock tank (A and B stay separate, as two-part salts must).
- Injection rate — the dilution ratio to run your doser or fertigation injector at.
- 50 lb bag counts — exactly how many bags of each part your program consumes, so the purchase order matches the grow.
It's the same self-serve pattern as our other brand calculators, tuned to King Solomon's dry chemistry and live catalog pricing.
Why dry two-part matters for commercial feeds
Liquid nutrients ship water. Dry salts don't—which is why large operations move to powders once volume justifies the mixing labor. The trade-off is discipline:
- A and B never mix concentrated. Calcium in the A tank and sulfates/phosphates in the B tank will precipitate if combined at stock strength. The calculator keeps the two recipes separate by design.
- EC is driven by dose, not by the bottle. With liquids you pour to a chart; with salts you weigh to a target. Getting grams-per-gallon right is the whole game.
- Bag math is real money. At $188.80 per 50 lb of Veg A/B and $210.04 per 50 lb of Bloom A/B, ordering one bag too many (or running short mid-cycle) has a dollar cost. The calculator's bag count is the line that protects the budget.
Operational workflow: from calculator to dock
- Pull your reservoir or batch-tank volume and your weekly feed cadence.
- Run the calculator for veg, then again for bloom, to size each phase.
- Cross-check the injection rate against your injector's ratio range (e.g. 1:100 / 1:128).
- Confirm bag counts, then add the bags to cart straight from the King Solomon product page.
- Validate against the published feed charts before your first full batch.
Product reference

Procurement considerations
- Order in whole bags. The calculator rounds to purchasable 50 lb units so you're not stranded with a partial cycle's worth of one part.
- Match A and B. Two-part programs consume A and B in a fixed relationship; the tool keeps them paired so you don't over-buy one and run dry on the other.
- Freight is calculated per shipment. King Solomon ships on quoted/calculated freight at checkout—palletized 50 lb bags aren't a parcel item—so lead time and delivery appointment planning apply just like any commercial pallet.
Common mistakes
- Combining A and B in one stock tank. Guaranteed precipitate. Keep two tanks.
- Copying a liquid feed chart onto dry salts. The concentrations don't transfer; weigh to EC.
- Buying bags without running the numbers. The point of the calculator is that bag count is an output, not a guess.
ROI
Dry two-part earns its keep on cost-per-gallon-fed and freight-per-pound of nutrient (you're not paying to ship water). The calculator protects that upside by making the mixing spec repeatable and the purchase quantity exact—the two places dry programs usually leak money.
FAQ
What is King Solomon fertilizer? A commercial two-part dry fertilizer line—Veg A&B and Bloom A&B—manufactured by PlantGeek and sold in 50 lb bags for hydroponic and soil programs.
Do I mix A and B together? No. Keep A and B in separate stock tanks at concentrate strength; they precipitate if combined. The calculator gives you two separate recipes.
How do I know how many bags to order? Enter your batch volume and program in the calculator—bag count is one of its outputs, rounded to whole 50 lb bags.
Can I use it for both hydro and soil? Yes. The tool covers hydroponic and soil programs; enter your batch and it sizes the stock tanks and injection rate accordingly.
How Order Junky Helps Commercial Operators
Order Junky pairs the King Solomon Dry Fertilizer Calculator with the live catalog and account pricing, so the numbers you calculate flow straight into a cart with the correct bag count and current pricing. No re-keying a spec into a separate order form, no ordering the wrong ratio of A to B. It's procurement intelligence—the feed math and the purchase order in one place.
