Concentrated 1-4-7 liquid bloom nutrient — engineered for high-yield flowering cycles in commercial hydro and soil-less grows.
TechnaFlora B.C. Bloom (1-4-7 NPK) is a highly concentrated liquid base nutrient formulated to drive flowering and reproductive growth in hydroponic, coco, and soil-based cultivation systems. Paired with B.C. Boost during the flowering stage, it delivers a complete macro and micronutrient profile — including chelated Mg, S, B, Cu, Mn, Mo, and Zn — with stable pH and minimal salt accumulation.
B.C. Bloom is the flower-stage component of TechnaFlora's B.C. Hydroponic Nutrients three-part system, alongside B.C. Grow (vegetative) and B.C. Boost (calcium-iron supplement used across both stages). The 1-4-7 NPK ratio is deliberately weighted toward phosphorus and potassium to support reproductive growth and dense floral development, while the nitrogen component is delivered exclusively as nitrate nitrogen for clean, efficient uptake.
Unlike formulations that reserve micronutrients for a single bottle, B.C. Bloom carries its own full complement of chelated micronutrients — copper (EDTA), manganese (EDTA), zinc (EDTA), boron, and molybdenum — so plants aren't relying solely on the Boost component for trace elements. This dual-micronutrient approach is a deliberate design choice by TechnaFlora and a meaningful difference in commercial runs where micronutrient deficiencies during late flower can cost yield.
The 20L format is the practical volume for mid-to-large commercial cultivation — enough to run a meaningful production cycle without constant restocking, and sized for easy reservoir management and weekly mixing.
B.C. Bloom 20L is appropriate for licensed cannabis and hemp operators running hydroponic systems (DWC, NFT, ebb-and-flow, recirculating drip), coco coir, or amended soil. The formulation is explicitly designed to work across all three substrate types, making it a practical choice for multi-room facilities that run different growing methods under one nutrient program.
The three-part B.C. system is structured so that operators run only two components at a time — during flower, that's B.C. Bloom plus B.C. Boost — which simplifies mixing, reduces the margin for error in a commercial environment, and keeps reservoir management straightforward for multiple cultivation staff. Facilities that have standardized on the B.C. system appreciate the consistency: the mixing ratios are fixed, printed on every label, and don't require a proprietary calculator.
The 20L size is the right entry point for commercial purchasing. It scales appropriately for rooms in the 1,000–5,000 sq ft canopy range depending on reservoir volume and feed frequency, and eliminates the per-liter overhead of buying in smaller increments.
B.C. Bloom is formulated — not buffered — to minimize pH drift. The practical result in a commercial system is fewer pH correction events during the flowering cycle, which matters when you're managing multiple reservoirs across a large facility. Stable pH also means consistent nutrient availability throughout the week between reservoir changes.
Salt accumulation is a chronic maintenance problem in recirculating hydroponic systems. TechnaFlora formulated the B.C. line to produce minimal salt build-up, which translates directly to reduced flush frequency, less downtime for system cleaning, and lower maintenance overhead per cycle.
The bloom-stage mixing ratio is 1 part B.C. Boost to 1 part B.C. Bloom per gallon, with Boost always added first. The standard starting dose is 1 tsp of each per gallon. This fixed ratio makes it easy to scale up for large reservoirs without recalculating on the fly, and the per-label instructions mean any team member can mix correctly without relying on a separate feed chart system.
Hydro Supply Co. carries the full TechnaFlora B.C. line — Grow, Boost, and Bloom — across all commercial volume sizes. For operators looking to standardize on the B.C. system, HSC can coordinate the complete nutrient program rather than requiring you to source each component separately through different channels.
Pricing through HSC reflects our direct accounts with the brands we carry — operators consistently find our wholesale pricing more competitive than retail or regional distributor alternatives. All orders ship nationally to licensed cannabis and hemp facilities across the United States.

B.C. Bloom is designed to be used with B.C. Boost during the flowering stage — the Boost component supplies supplemental calcium and chelated iron that B.C. Bloom does not contain on its own. Running Bloom without Boost will leave gaps in your calcium and iron delivery. B.C. Grow is only used during the vegetative stage and is replaced by B.C. Bloom at the flip.
B.C. Bloom is formulated for use in hydroponic systems, coco coir, soil-less media, and traditional soil. TechnaFlora designed the entire B.C. line to perform across all three substrate types, which makes it workable for facilities that run mixed growing methods.
During flowering, the ratio is 1 part B.C. Boost to 1 part B.C. Bloom per gallon of water. The standard starting dose is 1 tsp of each per gallon. Always add B.C. Boost to the reservoir first, then B.C. Bloom. Mixing instructions are also printed on every label.
TechnaFlora formulates the B.C. line specifically to minimize salt accumulation and pH drift. The formulations are built to maintain stable pH without constant adjustment — a meaningful advantage in large recirculating systems where pH swings and salt fouling are routine maintenance costs.
