Green Planet PK Spike
PK Spike is Green Planet’s concentrated bloom-phase accelerator, delivering a clean 0‑14‑15 ratio to push phosphorus and potassium exactly when flowers need it most. This highly soluble formula shifts plant energy toward flower building, driving rapid bud initiation, increased floral density, and a stronger finish. It’s engineered to stack neatly on top of any base program (GP3, Dual Fuel, etc.) without unnecessary fillers, just precision P and K for serious bloom performance.
During mid‑flower, plants demand large amounts of phosphorus for energy transfer and potassium for carbohydrate production, cell strength, and oil synthesis. PK Spike answers that demand with a potent shot of both, helping crops set heavier sites, ripen uniformly, and maintain quality under high-light or heavy-feeding conditions. Its low‑residue inputs keep reservoirs and lines clean while delivering fast plant availability.
Use PK Spike as a targeted tool from early‑ to mid‑bloom to amplify yield and quality. With correct timing and rate, you’ll see tighter stacking, improved resin output, and a confident, consistent finish across cultivars and environments.

Flower Mass Amplifier
High phosphorus and potassium ignite bud set, density, and resin production for heavier harvests.
Ultra‑High P/K Potency
Concentrated 0‑14‑15 formula delivers a strong nutrient spike with clean, fully soluble inputs.
Mid‑Bloom Turbocharge
Timed for weeks 2 – 5 of bloom to accelerate stacking, uniform ripening, and finish quality.A precision bloom booster for serious weight and quality gains.

Key Highlights

- Targets the flowering window with a balanced 0‑14‑15 analysis to support energy transfer and carbohydrate synthesis.
- Phosphorus fuels ATP production and flower initiation; potassium strengthens cell walls and enhances sugar movement.
- Potent, low‑residue formulation mixes clear and keeps recirculating systems running smoothly.
- Helps crops handle higher light intensity and heavier feeding by supplying the limiting bloom nutrients.
- Improves uniformity of ripening and overall harvest quality when applied at the correct stage.
- Compatible with GP3, Dual Fuel, and other base nutrients, easy to integrate into existing programs.
- Suitable for hydroponics, coco, and soil in both hobby and commercial environments.
- Simple, targeted additive that reduces guesswork and maximises bloom efficiency.
Directions for Use

Dilution Rate
- Root Drench: Apply 0.5 – 1 mL per 1 L of water between week 3 and 5 of flowering.
Application
- Shake well before use.
- Add to reservoir after base nutrients; never mix concentrates together.
- Timing guide: start Week 3 on short cultivars (≤65 days) or Week 4 on longer cycles; continue through mid‑bloom.
- Monitor EC, PK Spike is strong and can raise solution strength quickly.
Store in a cool, dry place away from direct light. Keep sealed to preserve quality.
