Description
Win the Mid-Bloom Window Where Flower Weight Is Made
Monkey Nutrients PK 9/18 is a concentrated phosphorus and potassium bloom booster aimed squarely at the most demanding part of flowering. Once bloom is fully underway, plants need far more P and K than a standard base feed provides, and PK 9/18 delivers those ratios in a form that's easy to add alongside your existing bloom nutrients in soil, coco or hydroponic systems, driving heavier flowers, denser buds and stronger yields.
Key Benefits
- High P and K ratio (9/18) targeted at peak flowering demand
- Increased bud density and overall flower weight
- Improved yield and stronger bloom development through mid-flower
- Stronger nutrient uptake during the demanding bloom stage
- Full harvest potential reached from your genetics
- All media: suits hydroponics, coco and soil
Fixing airy buds and disappointing flower weight?
Without enough phosphorus and potassium through the middle of flowering, plants produce airy, loose buds and lower yields than their genetics allow. PK 9/18 supplies the extra P and K exactly when flowers are being built, so plants channel that energy into thicker, denser buds instead of stretching or running short in grow tents and controlled grow rooms.
How to Use
- Dose: 2.5ml per 10 litres of water added to your nutrient solution
- Timing: use during weeks 5, 6 and 7 of flowering
- Method: mix thoroughly into the reservoir or watering container
- Alongside: run with your regular bloom feed in soil, coco or hydro
- Stop: discontinue before the final flush period
