Athena Nutrients Pro Line - Bloom — Professional-Grade Dry Soluble Flowering Nutrients
Best for: Commercial growers and serious hobbyists running drip systems or automated dosing setups who want professional results without the premium markup
Our thoughts
This is proper professional-grade kit at a price that makes sense. Athena Pro Bloom is used by some seriously demanding commercial operations and it shows. Clean, reliable, fully soluble, and plays nicely with all the major dosing systems. We bought heavy on this one — you benefit.
Athena Pro Bloom is a fully soluble dry fertiliser engineered specifically for the flowering stage. It's formulated with elevated phosphorus and potassium to drive flower density and size, plus sulfur to support the development of essential oils and aromatic compounds. Designed for growers running professional hydroponic systems — drip lines, stock tanks, automated dosers — it mixes completely at room temperature with zero sediment or clogging issues. Pair it with Athena Pro Core and you've got a complete, two-part flowering nutrition system that scales from single rooms to commercial operations.
How it compares
Athena Pro Bloom sits in the professional-grade segment of bloom nutrients.
- Comparable performance to General Hydroponics FloraPro, but at significantly lower cost per gallon of mixed solution
- Fully soluble powdered format — no particulates, no clogging, better value in bulk than liquid alternatives
- Compatible with all major dosing systems (Dosatron, Netaflex, Rhythm) rather than locked into one brand
- Trusted in high-end commercial gardens; proven track record with serious growers
In simple terms: you're getting commercial-scale nutrient reliability at a price that actually makes sense for large operations.
Usage guidance
Athena Pro Bloom is designed for growers using automated systems and stock tank preparation.
Stock concentrate preparation
Fill your stock tank half full with water. Slowly pour the Pro Bloom granules into the water while agitating thoroughly to dissolve completely. Top up to exactly 12.5 gallons and mix vigorously until all granules are solubilised. This concentrate is then dosed into your system or irrigation tank.
Dosing rates
Mix 4–7 grams per gallon of water, starting in week 2 of flowering. Dosing depends on your target EC level and whether you're running coco, hydro, rockwool, or soil. (Lighter feeding recommended in soil.)
System compatibility
Works with drip irrigation, drain-to-waste systems, and all major dosing equipment. The large-grind soluble formula dissolves completely with no sediment left in reservoirs or lines.
Pairing with Athena Pro Core
For every 1 gram of Pro Bloom, use 0.6 grams of Pro Core to hit your desired EC target. This creates a balanced macro and micro profile across the flowering stage.

Who this is for
- Commercial indoor growers and large-scale cultivation facilities running multiple rooms
- Serious hobbyists with automated drip systems or dosing equipment already in place
- Growers looking to reduce per-gallon nutrient costs without compromising performance
- Operations using coco, hydroponic rockwool, or inert media in controlled environments
- Anyone already familiar with mixing concentrates and targeting EC levels
Less suited to small-scale hand-watering growers or those without dosing experience — Pro Bloom assumes you're comfortable with stock tank preparation and automated feeding.
Our take
This is commercial-grade flowering nutrition at a realistic price. It's proven in serious grow houses, mixes cleanly, plays with any major dosing system, and doesn't leave you guessing about what goes in the tank. No unnecessary markup, no proprietary lock-in, just reliable kit that does exactly what it should.
Good time to buy while stock lasts. If you're running professional systems and want to cut nutrient costs without cutting corners on performance, worth picking up.
