Our take on the Front Row AG Part B

Front Row AG Part B is a fully soluble powder fertilizer meant to be used alongside Part A in a two-part feeding program for vegetative and flowering plants. It supplies phosphorus, potassium, magnesium and sulfur, with a proprietary acid and surfactants for mixing. The best new price is $20.00 at heirloomseedsdirect.com as of November 6, 2026, the low end of its recent range across four stores.

Pros

Fully soluble powder dissolves cleanly in water
Two-part system lets you adjust the P-K ratio by stage
Includes magnesium and sulfur alongside phosphorus and potassium
Powder form ships light and stores without leaking
Food-grade blue dye makes mixing strength easy to see

Cons

Useless without Part A; it is half of a two-part system
No NPK numbers printed in the listing, so dosing needs the feed chart
Blue dye can stain hands, tools and reservoir walls
5 lb tub is a large commitment for small gardens

Questions and answers

Do I need Part A to use Part B?: Yes. Part B is one half of a two-part program and is dosed together with Part A. Using it alone will not give a balanced feed.
What is the NPK of Part B?: Front Row does not print a single NPK on the Part B label; the ratio is set by how much A and B you mix. Follow the Front Row feed chart for your stage.
How much powder goes in a reservoir?: Dosing depends on your target EC and stage, so weigh per the feed chart rather than by scoop. Add Part A first, mix, then add Part B.
Is it safe for coco and hydroponics?: It is a fully soluble powder designed for reservoir and fertigation systems, including coco. Rinse lines and tanks periodically because the dye and organics can build up.
When is the price lowest?: The best new price seen is $20.00 at heirloomseedsdirect.com as of November 6, 2026. Prices across the four stores vary, so compare before buying.
Where is the Front Row AG Part B cheapest?: At heirloomseedsdirect.com, for $20.00, 60% under what the other stores charge, as of our latest check.
Where can I buy the Front Row AG Part B?: 9 stores we checked sell it, including heirloomseedsdirect.com, Cultivate, Greener Gardens, eBay, Front Row Agriculture.
