NPK 20-20-20 provides 20% nitrogen for chlorophyll and foliage, 20% available phosphate (P₂O₅) for roots and early flower signals, and 20% soluble potash (K₂O) for quality, colour and resilience. The even ratio makes this 20-20-20 fertilizer a reliable “do-most-things” feed that maintains balanced growth without pushing plants too hard in one direction.
- Use: Vegetables, flowers, shrubs, lawns and indoor plants when a general, balanced feed is desired.
- Mixing: Dissolve in water per label directions; apply to moist media. Suitable for foliar where appropriate.
- Tip: In very soft water or with heavy feeders, pair with a Cal-Mag supplement.
- Good practice: Monitor EC/ppm and pH in hydro/coco. Flush occasionally to prevent salt build-up.
