Evoponic Bud Bulk (0-47-34) — Professional PK Booster for Mid-to-Late Flowering
Best for: Advanced growers pushing their crop during weeks 3-6 of flowering who want serious phosphorus and potassium support without the premium brand markup
Our thoughts
We bought heavy on this one, so you benefit. Bud Bulk is a proper professional-grade flowering additive with amino acids and trace elements baked in—not just a bare PK dump. Extended application window (week 2 through harvest) gives you more control than single-week competitors. One for growers who know what they're doing.
Evoponic Bud Bulk is a professional-grade powder flowering additive formulated to deliver a concentrated dose of phosphorus and potassium when your plants need it most. At 0-47-34 NPK, it's built for serious growers who understand that mid-to-late flowering is when you lock in density, structure, and overall development. What sets it apart: it's enriched with 4% amino acids and 2% chelated trace elements, plus bio-active plant-derived stimulants—so you're getting more than just phosphorus and potassium. This is the essential enhancer for advanced growers working a proper flowering nutrition programme.
How it compares
Bud Bulk sits in the professional PK booster category, competing against single-use products like Canna PK 13/14, House & Garden Top Booster, and Grotek Monster Bloom.
-
Longer application window: Use from week 2 right through to final flush (stop only in the last week). Most competitors offer 1-4 weeks max.
-
Complete nutrition package: Amino acids and trace elements included, not just raw phosphorus and potassium
-
Bio-active blend: Plant-derived stimulants designed to be organic-certification friendly
-
Professional formulation: Built for growers who understand nutrient timing and want control over their programme
-
UK heritage: Evoponic is Britain's biggest independent manufacturer in this space, with established retail distribution
In practical terms: where competitors give you a narrow window or basic PK, Bud Bulk gives you flexibility, supporting materials, and proven formulation from a UK manufacturer you can actually buy from locally.
Usage guidance
Bud Bulk is a supplement to your main nutrient feed, not a replacement. Works with all standard hydroponic and soil-based programmes, and compatible with hard and soft water.
Dosage
Mix at 0.3-0.4g per litre of nutrient solution (or 4g per 10L). Small doses, serious results—don't overthink it.
Timing
Start at the end of week 2 of flowering and run it through to the final flush. Drop it out completely in week 7 (or whatever your final flush week is) to let the plant clean up naturally.
During mid-to-late flowering (weeks 3-6)
This is where Bud Bulk does its work. Your plants are building structure and density. The high phosphorus and potassium support energy transfer, sugar metabolism, and overall flower development. Run it alongside your standard feed—it's designed to layer on top, not replace what you're already doing.
Before flush
Drop the additive in your final week. Let your base nutrients run clean.
Why the extended window matters
Unlike single-week boosters, the flexibility here means you can adjust based on how your crop is performing. If density's lagging, you've got the window to push it. That control is what separates advanced programmes from one-size-fits-all feeding.

Who this is for
- Advanced growers running structured nutrient programmes who understand PK ratios and flower development
- Experienced indoor growers pushing for density and structure during mid-to-late flowering
- Growers with access to UK retailers and comfortable sourcing professional-grade additives
- Anyone running hydroponic systems where precise nutrient control matters
- Growers seeking organic-compliant products without sacrificing performance
- Experienced cultivators who want more control than single-week booster windows allow
This is not an entry-level product. It assumes you already understand your base nutrition and are looking to layer in a professional additive. If you're new to boosters, start with something simpler. If you know your programme inside out and want UK-manufactured professional support, this is worth the space in your cabinet.
Our take
Bud Bulk is a proper professional additive at clearance pricing. The amino acid and trace element blend gives it real depth beyond basic PK products, and the extended application window (week 2 through harvest) offers control you don't get from narrow-window competitors. Built by a UK manufacturer who understands what advanced growers actually need.
If you're running a structured programme and want professional-grade flowering support, good time to buy while clearance stock lasts. Does exactly what it should, day in, day out.
