Athena Blended Bloom B (0.7-6-5): Phosphorus-Potassium Hydroponic Bloom Nutrient
Athena Blended Bloom B (0.7-6-5, 55 Gallon) is the phosphorus-potassium side of Athena's Blended two-part bloom base. The formula carries 6% phosphate and 5% soluble potash with only a trace of nitrogen, which is exactly what mature plants need once they've shifted into reproductive mode. Phosphorus drives flower initiation and the energy transfer reactions inside the plant, while potassium handles osmotic balance, stomatal function, and the movement of sugars into the developing buds. The low nitrogen load keeps plants from running green when they should be stacking weight. All of this runs inside Athena's clean mineral chemistry, so you won't see the salt creep or residue buildup that older bloom formulas leave in drippers and reservoirs.
55-Gallon Drum for Commercial Flower Rooms and Multi-Light Operations
The 55-gallon drum is built for commercial scale. If you're running a multi-light flower room and going through Bloom B by the case every couple of weeks, the drum cuts your per-gallon cost and your restock frequency. It pairs with Athena Blended Bloom A (4.3-0-3.4) at a 1:1 ratio, and the Blended line is designed to be mixed direct into the reservoir without extensive pre-staging. On the low end of the sizing ladder, Athena also offers Bloom B in 2.5-gallon and 6-gallon jugs for mid-scale rooms. The 55-gallon format slots in when a facility outgrows those and wants to consolidate purchasing around a single drum that lasts a full flower cycle or more.
Key Features
- NPK 0.7-6-5: Phosphorus-forward bloom ratio with restrained nitrogen keeps plants focused on flower development instead of vegetative growth.
- Clean Mineral Chemistry: Athena's formulation runs without the residue buildup that fouls emitters and reservoir walls in long flowering cycles.
- Pairs 1:1 with Bloom A: Mixes at equal parts with Athena Blended Bloom A for the complete bloom base without complex ratio adjustments.
- 55-Gallon Commercial Drum: Reduces restock frequency and lowers cost per gallon for multi-light flower rooms running consistent bloom programs.
- Direct Reservoir Mixing: Formulated for straight addition into hydroponic reservoirs without pre-dilution or settling steps.
