BC sea kelp tonic with vitamin B1 — soil drench, foliar, or transplant soak across any medium.
TechnaFlora Thrive Alive B-1 Red is a mineral salt-fortified, 1-1-1 NPK seaweed tonic derived from British Columbian sea kelp and supplemented with 0.09% vitamin B1 — designed to reduce transplant shock, drive vegetative vigor, and support root development from clone through early flower. The 20 L format is sized for commercial operations running continuous production cycles.
Thrive Alive B-1 Red is TechnaFlora's mineral salt-fortified plant tonic built on a base of British Columbian sea kelp — specifically Macrocystis, Nereocystis, and Ascophyllum kelp species. The Red formulation is distinguished from TechnaFlora's Green variant by the addition of mineral salt nutrients (potassium nitrate, monopotassium phosphate, diammonium phosphate, potassium hydroxide, and ammonium nitrate), delivering a balanced 1-1-1 NPK alongside naturally occurring kelp-derived growth factors and 0.09% thiamine (vitamin B1).
The result is a product that functions simultaneously as a plant tonic, a root-zone conditioner, and a mild balanced nutrient supplement. It is liquid-concentrated, fully water-soluble, and compatible with any feed program — soil, soilless, coco, and recirculating or run-to-waste hydroponic systems.
Commercial cannabis and hemp operators running multi-stage production lines — propagation through early flower — will find the most utility in the 20 L format. The tonic earns its keep at three recurring high-stress moments in any production cycle: cloning and early root establishment, transplanting from clone to veg container or from veg to flower, and the transition into the first week of the bloom phase.
Licensed cultivators dealing with large weekly clone volumes, frequent transplant days, or any operation where plants are moving between environments will benefit from a standing protocol that incorporates Thrive Alive B-1 Red as a root soak, irrigation supplement, and foliar application. The 20 L volume reduces per-unit input cost and limits reorder frequency for facilities with meaningful weekly water volumes.
Thrive Alive B-1 Red supports three distinct application methods. As a root-zone drench or hydroponic reservoir additive, use at approximately 1/2 tablespoon (roughly 7.5 mL) per gallon of nutrient solution — run throughout vegetative growth and into early flower. As a transplant soak, use 1/2 teaspoon per quart of water and soak root zones for 15 minutes before transplanting to reduce shock and encourage rapid re-establishment.
As a foliar spray, mix at 1/2 teaspoon per quart of water and apply beginning one week after transplanting, then every two weeks through the vegetative cycle and into week one of flower. Do not apply foliar sprays under direct HID or high-intensity LED fixtures at full intensity — apply during lights-off or under reduced light to avoid photosensitized leaf burn. The kelp-derived growth factors and vitamin B1 promote cellular activity at the internodes and help maintain strong canopy color through the transition period.
For multi-room facilities with dedicated propagation, veg, and flower spaces, Thrive Alive B-1 Red integrates cleanly as a standing supplement at every plant-movement event. Many operators run it through propagation trays at cutting, use it as a drench for the first two to three irrigation events post-transplant, and then carry it into the feed schedule as a weekly foliar through veg. The balanced 1-1-1 NPK means it does not meaningfully distort macro ratios in a dialed-in feed program.
The 20 L container supports high-throughput facilities without constant reordering. Thrive Alive B-1 Red is also a logical pairing with TechnaFlora's broader nutrient lineup — including the B.C. three-part base and Rootech Cloning Gel — for operators looking to consolidate their supplement supply into a single vendor relationship.

Both are kelp-based tonics with vitamin B1, but the Red formulation is fortified with mineral salt nutrients (potassium nitrate, monopotassium phosphate, diammonium phosphate, potassium hydroxide, and ammonium nitrate), giving it a 1-1-1 NPK profile. The Green formulation is the natural/organic version without the mineral salt additions. For commercial operations that want the kelp and B1 benefits alongside a light macro contribution, Red is the appropriate choice.
Yes. It is a fully water-soluble liquid concentrate compatible with drip, NFT, ebb-and-flow, and hand-water setups. Mix into your reservoir or dilution tank at the labeled rate (approximately 7.5 mL per gallon of solution) before delivering through irrigation lines. Flush lines per your standard IPM and maintenance schedule.
TechnaFlora specifies that foliar applications should not be made when plants are under direct, full-intensity HID or high-output lighting. Apply during lights-off or during a low-intensity period to avoid photosensitized leaf burn. This is standard practice for any foliar application in a sealed or semi-sealed grow room.
The 1-1-1 NPK is low enough that it will not meaningfully shift macro ratios in a standard base program, even at full application rates. It is intended as a supplement and tonic layer — not a replacement for a base A/B or three-part nutrient. Mix it into your reservoir last, after your base nutrients and pH adjustment, and check EC before application.
For commercial facilities running Thrive Alive B-1 Red through clone trays, transplant soaks, and weekly foliar schedules simultaneously, the 20 L minimizes reorder frequency and typically lowers cost per liter. If your operation uses this product across multiple rooms or production stages, the 20 L is the practical bulk format.
