OMRI Listed organic kelp-and-B1 tonic — root zone or foliar, veg through early flower.
TechnaFlora Thrive Alive B1 Green is a concentrated, OMRI Listed organic supplement built on British Columbian sea kelp and vitamin B1 to support root development, increase nutrient uptake, and reduce transplant-related stress across soil, coco, and hydroponic systems.
Thrive Alive B1 Green is TechnaFlora's OMRI Listed organic plant tonic — the organic counterpart to their B1 Red formulation. The active base is a blend of three wild-harvested British Columbian sea kelps (Macrocystis, Nereocystis, and Ascophyllum) combined with vitamin B1 (thiamine). The kelp fraction delivers naturally occurring cytokinins, auxins, and trace minerals that support cell division and root architecture, while vitamin B1 is documented to ease the metabolic stress plants experience during transplanting and environmental shifts.
The guaranteed analysis is lean by design: 1.0% Soluble Potash (K₂O) and 0.01% Iron (Fe), fully water-soluble. This is a supplement and biostimulant, not a base nutrient — it is intended to run alongside your primary feed program, not replace it. TechnaFlora's own FAQ confirms both the Green and Red versions deliver equivalent agronomic results; the Green's OMRI certification makes it the go-to choice for certified organic operations or programs where input documentation matters.
Commercial cannabis and hemp operators running certified organic programs or maintaining OMRI-compliant input logs will find Thrive Alive B1 Green the cleaner choice over the Red variant. It fits naturally into any soil, coco, or hydroponic system without meaningfully shifting reservoir pH, which matters in tightly managed commercial recirculating setups.
The product is particularly well-suited for propagation-heavy operations — mother plant rooms, tissue culture transitions, large-scale clone batches, and any operation transplanting significant numbers of plants on a fixed schedule. It's also practical as a weekly foliar application throughout the vegetative cycle for facilities looking to maintain leaf health and minimize abiotic stress during environmental swings (HVAC adjustments, light schedule changes, canopy training). TechnaFlora's formulation is compatible with all major base nutrient brands, so it layers into existing programs without reformulation.
Thrive Alive B1 Green supports three distinct use cases in a single concentrated bottle. As a root-zone drench, it facilitates vigorous root development in both fresh cuttings and established transplants while protecting against transplant shock. As a foliar spray, it is applied at ½ tsp per quart of water — importantly, it should not be applied under active HID or high-intensity lighting to avoid foliar burn; schedule applications during dark periods or low-intensity windows. As a weekly foliar through vegetative growth into early flower, operators report a sustained 'green-up' effect: strong internode development and dense canopy color.
For propagation specifically, Thrive Alive B1 Green works in tandem with TechnaFlora's Rootech Cloning Gel — the drench application conditions the media while the gel drives root initiation at the cutting site. Standard hydroponic dosing is ½ tablespoon (approximately 7.5 ml) per gallon of nutrient solution. The product is extremely concentrated, so dosing discipline matters at commercial scale — small volumes go a long way across a large reservoir.
In a multi-room commercial facility, Thrive Alive B1 Green earns its place at two critical transition points: the clone/propagation room and the transplant-to-veg handoff. These are the stages where plant losses from stress, root damage, or environmental shock are most likely to compound across a production cycle. Running B1 Green at both stages — as a root soak pre-transplant and a drench post-transplant — adds a low-cost, well-documented insurance layer to those transitions.
For operations with organic certification or pursuing it, the OMRI listing means B1 Green can be used without jeopardizing certification status, provided the rest of the input stack is compliant. It also integrates cleanly into TechnaFlora's broader Recipe for Success program for facilities already running that full-line approach. Available in 1L through 20L sizes through HSC, so procurement can scale with production volume without switching products.

The Green formula is OMRI Listed Organic, making it suitable for certified organic production programs. The Red formula is fortified with mineral salt nutrients and is not OMRI Listed. TechnaFlora confirms both versions deliver equivalent agronomic performance — the choice typically comes down to certification requirements. A common approach in commercial facilities is to run Red in the reservoir and Green as the weekly foliar, though Green can be used in both applications.
Yes. TechnaFlora explicitly states their supplements, including Thrive Alive, are compatible with all major base fertilizer brands. It is designed as an additive to an existing feed program, not a standalone base. Confirm compatibility with your specific base by checking reservoir EC and pH stability after combining, as with any new input.
Mix at ½ tsp per quart of water. Apply during your dark period or when HID or high-intensity fixtures are off — the product should not be applied under active high-intensity lighting as it can cause foliar burn. TechnaFlora recommends beginning foliar applications one week after transplanting and continuing on a two-week interval through the vegetative cycle and into early flower.
Yes — Thrive Alive B1 Green is well-suited for propagation. As a root-zone drench at ½ tsp per quart, it conditions the media and supports root initiation in fresh cuttings. It pairs with TechnaFlora's Rootech Cloning Gel in a complementary protocol: the gel drives root site development while the B1 Green drench supports overall root-zone conditions. It also supports healthy mother plant maintenance when used as a rejuvenator prior to taking cuttings.
It goes directly into your nutrient solution at ½ Tbsp per gallon. The product is noted not to significantly alter pH levels, which reduces the risk of needing major adjustments after addition. That said, always add supplements after your base nutrients and confirm your final pH before feeding at commercial scale.
