Can I use Athena Pro Grow on its own?

No. Pro Grow is a vegetative component that must be used with Athena Pro Core, which supplies the nitrogen and calcium it lacks.

What dose do I use in the reservoir?

The direct reservoir rate is 4–6 g/gal during vegetative growth. For stock tanks, mix at 2 lb/gal, with a maximum of 2.5 lb/gal.

Does it work in a Dosatron or inline injector?

Yes. It is formulated for Dosatron, Netaflex, Rhythm, inline injectors and reservoir-based fertigation, and leaves no sediment when fully dissolved.

What media can I run it in?

Coco, rockwool, perlite, DWC, recirculating NFT and soil are all listed as compatible.

Our take on the Athena Pro Grow - 10 lb

Athena Pro Grow is a dry, fully water-soluble vegetative fertilizer in the Pro Line, with a 2-8-20 NPK plus 3% magnesium, 8% sulfur and DTPA-chelated iron. It carries no urea or ammoniacal nitrogen, so it feeds nitrate nitrogen only, and it is built for injector and reservoir fertigation in coco, rockwool, perlite, DWC, NFT and soil. It must be paired with Athena Pro Core, which supplies the nitrogen and calcium the Grow formula leaves out. The best new price is $57.75 for the 10 lb bag at HTG Supply as of November 6, 2026, with 4 stores listing it new.
