Blossom Blaster by Grotek is the definitive flowering initiator that transforms the structure of your plants, stopping vertical growth to focus all energy on creating abundant bud sites immediately. This powerful supplement acts as a biological signal that tells your crop it's time to stop growing leaves and start producing the flowers you're looking for.

Stop the stretch and multiply your production

Does it happen to you that, when switching the photoperiod, your plants stretch uncontrollably, resulting in long internodes and airy buds? It is one of the most common frustrations: seeing how your crop grows in height but not in volume, wasting the potential of your indoor setup.

This inconsistency not only affects the final weight of the harvest but also complicates the management of the crop. Having lights too close burns the tips, and having them too far reduces production. Trying to guess how much they will stretch this time generates anxiety and makes you feel like you are not in control of the situation.

Blossom Blaster is the solution to stabilize your crop. By applying it right at the beginning of flowering, you drastically reduce internodal distance. This means you get compact plants, with a structure ready to support heavy and dense colas, making every watt of light count.

Why Blossom Blaster guarantees a canopy full of buds

The secret lies in its extreme concentration of high-quality minerals. With an NPK of 0-39-25, this additive provides a massive shock of Phosphorus and Potassium exactly when the plant needs it most to change its hormonal cycle. Unlike other cannabis fertilizers that are used throughout the cycle, this is a precision tool.

By using it, you are ensuring that the plant's energy is not wasted on stems, but is directed to the flower nodes. This creates a "horizontal" effect, filling the branches with pre-flowers that will later become rock-hard buds. It is the perfect foundation for a record-breaking harvest.

Key factors to master your flowering phase

  • Concentration: Being a highly concentrated powder, you need very little quantity to see huge changes.
  • Timing: It is designed for the first weeks of flowering (pre-flowering), the critical moment to define the structure.
  • Compatibility: It works perfectly in soil, coco, and hydroponic systems, ensuring versatility regardless of your growing style.
  • Stress reduction: Its ingredients help the plant cushion the stress of the photoperiod change and transplanting.
  • Synergy: It prepares the plant to later receive fattening boosters like Monster Bloom or the complete Grotek Indoor Kit.

How to use Blossom Blaster for professional results

  1. Preparation: Fill your tank with water and add your base nutrients first.
  2. Mixture: Dissolve 1 gram of Blossom Blaster for every 10 liters of water (0.1g/L). It is very powerful, do not exceed the dose.
  3. Application: Apply it in irrigation when the first pistils (white hairs) begin to appear, usually in the first or second week of flowering.
  4. Repetition: You can make a second application two weeks later to reinforce the effect.
  5. Control: Observe how the vertical growth stops and the internodes shorten.

Advantages and benefits of total control

  • More flowers per branch: By shortening the internodes, you get longer and more continuous colas.
  • Maximum light efficiency: Compact plants make better use of your Full spectrum led grow lights.
  • Cost savings: Its high concentration means a small jar lasts for many crops.
  • Consistency: You will achieve predictable and repeatable results in each cycle, eliminating the "luck" factor.

Frequently Asked Questions

Can I use it together with Monster Bloom?

They are not used at the same time. Blossom Blaster is for the beginning of flowering (initiation) and Monster Bloom is for the final stage (fattening). Using them in sequence is the perfect strategy.

Is it suitable for autoflowering plants?

Yes, you can use it on autoflowers just when you see the flowering start automatically, helping to maximize their limited size.

Do I have to correct the pH after adding it?

Yes, always measure and adjust the pH after adding all nutrients to the water. Being a mineral product, it is crucial that the pH is in the correct range (5.8 - 6.5 depending on the medium) for absorption to be optimal.

Personal Experience of Pevgrow’s CEO (Alan)

In my years of testing products, few have surprised me as much in terms of efficiency as Blossom Blaster. I remember a crop of Sativas that were getting out of hand in height; I applied Blossom Blaster in the first week of 12/12 and the change was radical. The plants stopped stretching as if they had hit a ceiling and began to sprout pistils everywhere.

For me, it is essential when I grow genetics that I don't know well or that tend to stretch a lot. It gives me the peace of mind of knowing that the structure will remain compact and manageable. If you are looking for that "sea of green" effect full of dense points, this is the secret weapon you are missing in your arsenal.
