Water-soluble PK booster designed for heavier, higher-quality flowering.
Buddha’s Tree PK 9-18 is a fully soluble phosphorus and potassium additive made to support plants during the key flowering window, when demand for P and K rises and bulk is built. It mixes cleanly into reservoirs and feed tanks, making it a solid choice for hydroponics, coco, and soil grows where you want a reliable PK push without clogging lines or leaving residue.
Why growers use PK 9-18
- Supports flower development by boosting P and K when plants shift energy into bloom production.
- Fully soluble for cleaner mixing and easier use in tanks, drippers, and recirculating systems.
- Helps improve finish by supporting the plant’s natural processes around oils, sugars, and density during bloom.
- Built for performance in modern feeding programs where consistency and repeatability matter.
How to use
- Use during the flowering phase, typically around the peak bloom period.
- Always follow the manufacturer’s dosage guidance and start low if you are new to PK boosters.
- Monitor EC and pH after mixing. PK products can raise EC quickly if over-applied.
- Do not combine with other strong PK boosters in the same feed unless your schedule specifically calls for it.
Best for
- Growers wanting a stronger bloom push during peak flowering
- Hydro and coco setups where clean, soluble additives matter
- Anyone chasing improved density and finish without messy mixing
Available sizes
- 100ml
- 250ml
- 1L
- 5L
Tip: PK boosters work best when the base feed is already balanced. If you are seeing burnt tips or high runoff EC, reduce base strength before adding more PK.
