TechnaFlora B.C Bloom 10L - Nutrients

What B.C. Bloom Is

B.C. Bloom is the flowering component of TechnaFlora's B.C. Hydroponic Nutrients three-part system — a line built around B.C. Grow (veg), B.C. Boost (Ca/Fe supplement), and B.C. Bloom (flower). The 1-4-7 NPK ratio keeps nitrogen deliberately low during bloom while driving elevated phosphorus and potassium, which are the macronutrients most directly tied to flower development and reproductive growth.

Unlike single-component bloom formulas that rely on a separate part for micronutrients, B.C. Bloom carries its own full micronutrient package: Magnesium (0.852%), Sulfur (1.37%), Boron (0.0072%), Copper (0.00268%), Manganese (0.024%), Molybdenum (0.00012%), and Zinc (0.0139%). This means the flowering nutrient itself is nutritionally complete, and B.C. Boost layers in supplemental calcium and iron on top.

Derived from Potassium Nitrate, Magnesium Sulfate, Monopotassium Phosphate, Potassium Sulfate, Manganese EDTA, Boric Acid, Zinc EDTA, Copper EDTA, and Sodium Molybdate — the chemistry is salt-form but formulated, not simply buffered, to minimize pH swing across reservoir cycles.

Who Should Be Running This

B.C. Bloom is purpose-built for commercial and craft licensed operators who want a proven, cost-effective base nutrient without proprietary lock-in. The three-part system's mixing ratios are transparent and printed on every label, which makes it straightforward to hand off to a cultivation team without creating a black-box feed program.

It performs in recirculating hydro (DWC, NFT, flood-and-drain), run-to-waste coco, and soil — which makes it a practical choice for multi-facility operators or those running different growing styles across their licensed footprint. In hydroponic systems, the formula is dosed every irrigation cycle. In soil-based grows, frequency is reduced to avoid salt accumulation in the medium.

The 10-liter format is the right entry point for commercial operations: large enough to run a meaningful harvest cycle without constant restocking, but not a 65L or 205L bulk commitment if you're trialing the line.

Key Formulation Features

The B.C. system's standout technical feature is that both B.C. Grow and B.C. Bloom each carry independent, full-spectrum micronutrient packages. This is a meaningful difference from three-part systems where micronutrients are consolidated into only one bottle — if you ever adjust or omit a part, you're not inadvertently stripping micros from the feed.

Formulated to minimize pH drift, not just buffered after the fact. Operators running tight pH windows in recirculating systems report stable solution chemistry across reservoir holds, which reduces the labor cost of constant pH correction and adjustment.

Low salt accumulation profile keeps system and medium cleaner between flushes. In commercial runs with high irrigation frequency — particularly recirculating hydro — this reduces the risk of nutrient lockout from salt buildup and cuts down cleaning time and expenditure between cycles.

B.C. Boost must be added to the reservoir first before B.C. Bloom is introduced. This mixing sequence matters: Boost contains high calcium and iron, and pre-mixing it ensures those elements are fully dissolved and won't bond with phosphorus or other elements in Bloom. This is a firm protocol requirement, not a suggestion.

How It Fits a Commercial Build

B.C. Bloom slots in as the flowering base nutrient from the start of the flip through pre-harvest flush. Paired with B.C. Boost at a 1:1 ratio per gallon, it covers macros and chelated micros for the reproductive phase. Operators can layer TechnaFlora's own supplement line — MagiCal, Awesome Blossoms, SugarDaddy — on top via the Recipe for Success mixing chart, which maps stage-by-stage combinations rather than week-by-week schedules.

The 10L container size works for facilities running multiple flowering rooms simultaneously or operators who want to standardize on a single SKU for bloom-phase feeding without over-investing in bulk volume before the program is fully dialed. TechnaFlora scales the B.C. line up to 65L, 205L, and 1000L totes for high-volume operations — HSC can source those formats as well.

Storage is straightforward: cool, dark room, away from HID lighting and humid grow-room conditions. Shelf life is two years from manufacture date. Each batch is numbered and coded at the TechnaFlora facility for traceability.
