Plagron PK 13-14 is a concentrated flowering additive that delivers an optimal ratio of phosphorus (P) and potassium (K) to meet the increased nutritional demands of plants during the mid-flowering phase. Phosphorus supports energy transfer and flower formation, while potassium plays a key role in bud development, water regulation and overall plant strength.
This powerful PK booster is designed to be used for a short period during peak bloom, working alongside your base flowering nutrients to maximise bud size and density without overfeeding. Suitable for soil, coco and hydroponic systems, PK 13-14 integrates easily into any nutrient programme.
Key Features & Benefits
- High Phosphorus & Potassium Formula: Supports intense flower and bud development.
- Boosts Bud Size & Density: Encourages larger, heavier and more compact flowers.
- Increases Final Yield: Optimised PK levels help maximise harvest weight.
- Targeted Mid-Bloom Use: Designed for peak flowering when nutrient demand is highest.
- Highly Concentrated: Effective at low dosages.
- Easy to Apply: Simple liquid additive that mixes easily with nutrient solutions.
- Multi-Medium Compatible: Suitable for soil, coco coir and hydroponic systems.
How to Use
- Shake well before use.
- Add 2 ml per litre of water.

Frequently Asked Questions (FAQ)
When should I use Plagron PK 13-14?
Use it during peak flowering, usually for one week in the middle of the bloom phase when buds are rapidly developing.
Can PK 13-14 be used in all grow mediums?
Yes, it’s suitable for soil, coco and hydroponic systems.
Is PK 13-14 a complete bloom nutrient?
No, it’s a bloom booster and should be used alongside your base flowering nutrients.
Can I use PK 13-14 with Green Sensation?
No, Green Sensation already contains PK and should not be combined with additional PK boosters.
Will PK 13-14 improve bud hardness?
Yes, potassium plays a key role in producing firmer, denser flowers.
During peak flowering, plants require significantly higher levels of phosphorus and potassium to support energy transfer, bud expansion and flower density. Plagron PK 13-14 delivers these nutrients in a precise ratio at exactly the right time, helping growers achieve bigger buds, increased density and heavier yields. Easy to use and highly effective, it’s an essential bloom booster for anyone looking to maximise flowering performance and harvest weight.
