Green Planet Bud Booster — Flowering Nutrient Powder for Bigger Yields
Best for: Growers wanting a straightforward bloom booster that works across soil, coco, and hydro without the premium price tag
Our thoughts
This is a solid entry-level bloom booster that punches well above its price point. High phosphorus and potassium, easy to use powder format, and it works with everything — exactly what new growers need when they're adding their first flowering additive. One we sell a lot of, and for good reason.
Green Planet Bud Booster is a powdered PK additive designed to boost flower size and density during the flowering stage. With an NPK ratio of 1-50-30, it delivers serious phosphorus and potassium exactly when your plants need it most — plus boron and amino acids to help everything work properly. It's a proper flowering nutrient supplement at a price that actually makes sense.
How it compares
This sits firmly in the accessible entry-to-mid tier of bloom boosters.
- Same professional-grade NPK ratio as liquid concentrates, but in powder form (easier storage, lower cost per dose)
- Simpler formula than premium competitors — no unnecessary fluff, just the nutrients that matter
- Works across all growing media and hydroponic systems (soil, coco, DWC, NFT, everything)
- Significantly cheaper per application than Advanced Nutrients Big Bud or Element Nutrients Flower Fuel
In simple terms, you're getting professional results without paying professional premium pricing.
Usage guidance
Bud Booster integrates into your existing nutrient program. It's not a replacement — it's an addition that kicks in when buds start forming.
Dosing
Use at 6g per 20 litres of water (roughly 1 teaspoon per 5 gallons) from the moment buds form. Continue with every nutrient application throughout the flowering stage, then stop completely in the final week before flushing.
All growing systems
Works with soil, coco, DWC, NFT, drip, hand watering — whatever setup you're running. No restrictions, no compatibility issues.
Important
Bud Booster is concentrated. If you're using sensitive varieties or notice plants getting stressed, lower your base nutrient EC slightly to compensate. Don't use it alongside other PK additives — this does the job alone.
Why it works
The high phosphorus promotes flower formation and increases overall yield. Potassium improves flower quality and starch production. Boron helps transport sugars to the developing flowers. Everything dissolves clean and gets absorbed fast.
