TechnaFlora B.C Grow 4L - Nutrients

What It Is

TechnaFlora B.C. Grow is a highly concentrated liquid base nutrient designed to drive vegetative development. It carries an NPK of 1-3-6 and is built around a nitrate-nitrogen source combined with magnesium (1.11%), sulfur (1.44%), and a full suite of chelated micronutrients — boron, copper, manganese, molybdenum, and zinc. Derived from Potassium Nitrate, Magnesium Sulfate, Monopotassium Phosphate, Potassium Sulfate, and chelated trace element sources including Manganese EDTA, Zinc EDTA, and Copper EDTA.

Unlike formulations that load micronutrients into only one part of the feed program, B.C. Grow carries its own complete micronutrient profile independent of B.C. Boost. This means plants receive trace element coverage at the base level of the vegetative feed, not solely as a function of the Boost ratio.

Who It's For

B.C. Grow is suited for licensed cannabis and hemp cultivation operations running any recirculating or drain-to-waste hydroponic system — NFT, DWC, ebb-and-flow, drip — as well as coco and soil-based programs. The formulation is media-agnostic by design, which makes it practical in facilities that run more than one growing method across rooms or phases.

Operations that need a straightforward, label-documented feed program benefit from B.C. Grow's stage-based mixing protocol. The 3-part system (Grow, Boost, Bloom) uses defined part ratios per growth stage rather than week-by-week EC targets, which reduces training overhead for cultivation teams working across multiple sites or shifts. The 4L size is the practical working unit for mid-size and larger operations that aren't yet at drum-volume consumption.

Key Formulation Features

The formulation is designed — not buffered — to minimize pH fluctuation during the vegetative feed cycle. This is a meaningful distinction: buffering temporarily masks pH drift; a properly balanced ionic ratio avoids inducing it. Operators running recirculating reservoirs with hard or variable source water report more stable reservoir pH over multi-day hold periods compared to unbuffered concentrate systems.

Minimal salt accumulation is a function of the inorganic salt selection — highly soluble potassium and magnesium salts at the concentrations used leave less residual buildup in dripper lines, manifolds, and reservoir walls. This reduces flush frequency and system cleaning time, a measurable operational cost in high-canopy commercial grows. All chelated micronutrients (Cu, Mn, Zn) use EDTA chelation for reliable uptake across the pH range typical of hydro and coco programs.

How It Fits a Commercial Build

B.C. Grow is used during the vegetative stage at a 2:1 ratio of B.C. Boost to B.C. Grow per gallon of reservoir or feed water. Always add B.C. Boost to the water first before adding B.C. Grow to maintain proper ionic sequencing. During the flowering stage, the program transitions to B.C. Boost paired with B.C. Bloom — B.C. Grow is phased out at the flip.

TechnaFlora publishes a Recipe for Success mixing chart and an online Recipe Calculator that accounts for growth stage, medium type (hydroponics, DWC, soil, coco 50% mix), and reservoir volume. This gives cultivation managers a documented dosing reference to build SOPs around, which is increasingly relevant for state-licensed operations that require nutrient input logs as part of their compliance records.

The 4L bottle is available as a standalone unit through HSC, and can be ordered alongside B.C. Boost and B.C. Bloom to complete the system. Larger volume packaging (10L, 20L, 65L, 205L, 1000L) is available through the line — contact HSC to discuss volume pricing on higher-quantity runs.
