Kelp-derived B1 tonic for root development, transplant recovery, and veg-to-flower transitions.
TechnaFlora Thrive Alive B-1 Red is a mineral salt–fortified, concentrated liquid supplement built on British Columbian sea kelp — delivering a balanced 1-1-1 NPK alongside 0.09% Vitamin B1 to support root establishment, reduce transplant stress, and sustain canopy health through vegetative growth and into the first week of flower. Compatible with soil, soilless, and hydroponic production systems.
Thrive Alive B-1 Red is TechnaFlora's mineral salt–fortified plant tonic — a liquid concentrate built on premium British Columbian sea kelp (Macrocystis, Nereocystis, and Ascophyllum species) and reinforced with mineral salts for a balanced 1-1-1 NPK (1% N, 1% P₂O₅, 1% K₂O). The addition of 0.09% Vitamin B1 (thiamine) differentiates the Red formulation from TechnaFlora's organic-only Green variant. B1 is widely used in commercial horticulture as a biochemical signal supporting root initiation and abiotic stress mitigation — particularly relevant during propagation and transplant windows where root systems are most vulnerable.
The nitrogen fraction breaks down as 0.5% ammoniacal, 0.3% nitrate, and 0.2% other water-soluble nitrogen — a distribution that provides multiple uptake pathways. Source materials include potassium nitrate, monopotassium phosphate, diammonium phosphate, potassium hydroxide, and ammonium nitrate, in addition to the three kelp species.
Licensed cannabis and hemp operators running propagation programs will find the most immediate application here. Thrive Alive B-1 Red is structured around the two highest-risk transitions in a commercial cultivation cycle: the clone/cutting stage and the transplant window. At both points, root system integrity determines how fast a plant enters productive growth — and transplant stress that sets a plant back even a few days compounds across a multi-thousand-square-foot canopy.
It's equally relevant for operators running integrated feed programs who need a compatible tonic that works across soil, coco, rockwool, or recirculating hydroponic systems without disrupting their primary nutrient regime. Facilities running TechnaFlora's Recipe for Success (RFS) program will recognize this product as a standard component of that ten-product system. Operators running other base nutrient programs can still run Thrive Alive B-1 Red as a standalone supplement in propagation trays or as a foliar during veg.
Soil / root zone drench: Applied at the cutting or transplant stage, Thrive Alive B-1 Red conditions the root zone and supports early root mass development. It is designed to pair with rooting gels during propagation to accelerate viable root system establishment.
Foliar spray: Applied through the vegetative cycle and into the first week of flower, foliar applications increase nutrient uptake at the leaf surface and keep canopy tissue healthy and lush. Avoid foliar application under active HID or direct high-intensity light to prevent foliage burn — apply during the lights-off window or under lower-intensity conditions.
Rejuvenation / mother plant maintenance: Applied to mother plants prior to taking cuttings, the tonic sustains shoot production and overall plant health, contributing to more consistent cutting quality across production cycles.
Thrive Alive B-1 Red carries a 1-1-1 NPK — low and balanced — so it does not materially shift the N-P-K ratios of an existing nutrient program when used at label rates. This makes it practical to slot into propagation protocols, transplant procedures, and weekly foliar schedules without rebuilding EC targets or recipe sheets.
The 500mL bottle size is the trial and small-run format. Operators moving it at volume across multiple rooms or facilities should request a quote for the 1L, 4L, or 10L formats, which reduce per-application cost significantly. As a supplement used across cloning, veg, and early flower, a single SKU covers three phases of production — useful for facilities looking to keep additive SKU count low without sacrificing coverage.

Both products share a kelp-and-B1 foundation, but Thrive Alive B-1 Red is fortified with mineral salt nutrients (potassium nitrate, monopotassium phosphate, diammonium phosphate, etc.), giving it a 1-1-1 NPK profile. Thrive Alive B-1 Green is an organic-only formulation without the mineral salt additions. Red is the more common choice for commercial operators who want measurable nutrient delivery alongside the seaweed and B1 components.
Yes. The product is compatible with hydroponic, soil, and soilless (coco, rockwool, perlite) systems. In recirculating systems, use it as you would any liquid additive — measure into your reservoir after your base nutrients, confirm your EC hasn't shifted beyond target, and monitor pH as you would with any mineral addition.
TechnaFlora's guidance positions foliar application through the vegetative cycle and into the first week of flower. Root zone drenching is most applicable at propagation and transplant. Most commercial cannabis operators discontinue foliar applications entirely by the end of week one of flower to avoid issues with residual moisture and flowering-stage canopy management. Consult your state's pesticide/supplement application regulations for any compliance requirements.
At typical application rates, the additive contribution to EC is minimal. The 1-1-1 ratio is low and balanced, so it generally does not require significant adjustment to your base program's recipe or EC ceiling. That said, always dial in with your specific base nutrients and measure EC after adding any supplement before applying to your full production crop.
The 500mL is a viable trial or small-run size. For production-scale use across multiple rooms, the 1L, 4L, and 10L formats offer a lower cost-per-application. Request a quote through HSC and we can size the format to your program and volume.
