THROUGH THE Cultivator's LENS Hands-On Evaluation

  • You are adding a P-K booster to your feeding schedule because your base nutrient line is not keeping up with the increased hunger of your plants once they begin forming buds.
  • You are looking to target higher bloom density and color quality because your current yield feels thin or underdeveloped during the final weeks of the cycle.

  • The 0-6-4 ratio is pretty standard, but we find the inclusion of B1 helps the plants handle the stress of high-intensity lighting better than using phosphorus alone.
  • It mixes cleanly into water without leaving a heavy film in the reservoir, which makes it an easy addition for automated drip systems.

  • Growers who added this during the mid-to-late flowering stages say they saw a noticeable increase in overall density compared to previous runs without a bloom additive.
  • Users managing climate-controlled environments report that adding this helped their plants maintain vigor during periods of higher temperatures.

Vivosun Bloom Juice 0-6-4 Liquid Flowering Supplement

Once plants flip to flower, their demand for phosphorus and potassium climbs, and a base nutrient built for all-around growth may not keep pace. Vivosun Bloom Juice is a concentrated 0-6-4 flowering additive that adds extra phosphorus and potassium during bloom. It supports flower development, size, and density from the first week of flower through harvest.

Phosphorus supports flower development and fruit quality, while potassium contributes to flower size and color and strengthens overall plant growth. Vivosun also fortifies Bloom Juice with vitamin B1, which supports root activity, energy metabolism, and nutrient uptake. It can also help plants cope with transplant shock and environmental swings during the demanding flowering phase.

Bloom Juice is 100% water-soluble and compatible with hydroponics, aeroponics, DWC, coco coir, soil, and other growing systems, indoors or outdoors. Use it on its own or combined with your base nutrients and other additives during flowering. Start at a conservative rate and adjust to find what works best for your setup. It's available in 8 oz and 32 oz bottles.

Frequently Asked Questions

When should I use Bloom Juice? +

Vivosun Bloom Juice is formulated for the flowering stage. Add it to your feeding program once plants begin to flower and continue through the bloom cycle to support flower development.

What does the 0-6-4 ratio mean? +

The numbers show the nitrogen, phosphorus, and potassium content. Bloom Juice contains no nitrogen, 6% phosphorus, and 4% potassium, which makes it easy to layer on top of your base nutrients during flower.

Why does Bloom Juice include vitamin B1? +

Vitamin B1 supports root activity, energy metabolism, and nutrient uptake. It can also help plants handle transplant shock and environmental fluctuations during the demanding flowering phase.

Can I combine Bloom Juice with other nutrients? +

Yes. Bloom Juice can be used as a standalone additive or combined with your base nutrients and other additives. Its nitrogen-free formula adds bloom-stage phosphorus and potassium without changing your nitrogen feed.

Is Bloom Juice compatible with hydroponics and DWC? +

Yes. It's 100% water-soluble and designed for hydroponics, aeroponics, DWC, coco coir, soil, and other growing systems. It mixes cleanly into reservoirs and irrigation lines.

How much Bloom Juice should I use? +

Vivosun recommends experimenting with the dosage to find the best amount for your specific plants and setup. Start conservatively, watch how your plants respond, and increase gradually as needed.

Which size should I choose? +

The 8 oz bottle is a good fit for smaller grows or first-time use. The 32 oz bottle suits larger gardens and growers who feed Bloom Juice throughout every flowering cycle.
