Description
House & Garden PK 13-14 stimulates rapid fruit and flower formation by providing your plants with a large amount of phosphorus and potassium over a period of 3 to 4 days.
This creates the illusion of a drought within the plant, stopping the growth cycle completely and forcing it into the flowering cycle. Phosphorous and potassium are important building blocks for the plant.
- Dilution / Dose
- 1.5ml per litre.
- When To Use
- As a short, sharp 3–4 day burst to force the plant from growth into flowering — not run continuously through bloom.
- Substrate Fit
- Soil, coco and hydro.
- Grower Notes
- Don't run alongside another PK booster such as Shooting Powder or Top Shooter — pick one, not both.
