Calcium- and iron-fortified base nutrient — Part 2 of TechnaFlora's proven 3-part B.C. system.
TechnaFlora B.C. Boost (3-0-2) is the calcium- and iron-fortified backbone of the B.C. Hydroponic Nutrients trio, running alongside B.C. Grow in veg and B.C. Bloom in flower to deliver stable, low-salt nutrition through every stage of the crop cycle. Engineered to minimize pH fluctuation without buffering, it keeps reservoir management predictable at commercial scale.
B.C. Boost is Part 2 of TechnaFlora's B.C. Hydroponic Nutrients system — a three-part base nutrient line that has been a fixture in professional cultivation programs for years. Unlike single-part or two-part base systems, the B.C. line separates macro and micronutrient delivery across B.C. Grow, B.C. Boost, and B.C. Bloom, giving cultivators granular control over what the plant receives at each growth stage.
B.C. Boost carries an NPK of 3-0-2 and is specifically formulated to contribute supplemental calcium and iron — elements that both B.C. Grow and B.C. Bloom rely on Boost to deliver. This design avoids the calcium antagonism issues that arise when Ca is packed into the same part as phosphate-heavy components. The result is a cleaner, more bioavailable mineral delivery across the full stack.
B.C. Boost in the 4L size is the right entry point for licensed cannabis and hemp operators running multi-light rooms, small-to-mid commercial facilities, or R&D bays who want to standardize on the full B.C. three-part system before committing to larger drum volumes. The 4L is also common in multi-site operations where individual facility managers control their own nutrient inventory.
The system works across hydroponic (recirculating and drain-to-waste), coco coir, rockwool, and amended soil substrates — making it a practical choice for facilities running varied cultivation methods across multiple rooms or buildings. TechnaFlora positions the B.C. line for high-yield production, and commercial operators running dense canopies will find the calcium and iron contribution from Boost particularly relevant for structural stem integrity and chlorophyll production under high-intensity lighting.
B.C. Boost's 3-0-2 NPK delivers nitrate nitrogen and soluble potash alongside its primary function: supplemental calcium and iron to complete the micronutrient profile established by the Grow and Bloom parts. The formulation is engineered — not chemically buffered — to minimize pH fluctuation, which means operators running automated dosing and inline pH monitoring will see more consistent set-point stability compared to buffered systems that can drift as buffer capacity is consumed.
Salt accumulation is another meaningful metric at commercial scale. The B.C. system is formulated to produce low salt build-up, which directly reduces flush frequency and system maintenance overhead in recirculating hydro setups. Mixing ratios are straightforward: in vegetative stage, use 2 parts B.C. Boost to 1 part B.C. Grow per gallon; in flowering, use 1 part B.C. Boost to 1 part B.C. Bloom per gallon. TechnaFlora recommends maintaining solution pH between 5.5 and 6.5 for best results.
For facilities scaling up or standardizing their nutrient program, the B.C. three-part system offers a predictable, well-documented feed schedule that reduces training overhead and inconsistency between staff and shifts. The label-printed mixing instructions and the binary veg/flower ratio structure make it easier to enforce SOPs across multiple rooms or facilities without relying on proprietary software.
Hydro Supply & Co. supplies B.C. Boost through our direct TechnaFlora account and can coordinate the full B.C. system — Grow, Boost, and Bloom — together. Larger drum formats (10L, 20L, 65L, and above) are available for high-volume operations. Reach out via the quote form below and we'll put together the right volume configuration for your canopy size and feeding frequency.

No — B.C. Boost is designed as Part 2 of a three-part system and is intended to be used alongside B.C. Grow in vegetative stage and B.C. Bloom in flower. It provides the calcium and iron that complete the nutrient profile established by the other two parts. Using it as a standalone base nutrient will result in an incomplete feed program.
In vegetative stage, the recommended ratio is 2 parts B.C. Boost to 1 part B.C. Grow per gallon of water. In flowering, use 1 part B.C. Boost to 1 part B.C. Bloom per gallon. Always add B.C. Boost first when building your reservoir solution.
Yes. The B.C. line is formulated for hydroponic use and is specifically engineered to produce low salt build-up in recirculating systems, reducing the frequency of full reservoir flushes. It is also compatible with drain-to-waste, coco coir, rockwool, and soil-based cultivation setups.
B.C. Boost's role in the system is to deliver nitrogen, potassium, calcium, and iron — not phosphorus. Phosphorus delivery is handled by B.C. Bloom (which carries phosphate) in the flowering stage. This separation prevents calcium-phosphate antagonism in the reservoir, keeping nutrients bioavailable rather than precipitating out.
The 4L is practical for multi-light single rooms, R&D bays, or facilities that manage nutrient inventory at the room level. High-volume commercial operations typically step up to the 10L, 20L, 65L, or larger drum formats.
