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.

Reviews From Our Gardener's
Hedges are looking amazing since started using NPK 20-20-20 – with greater foliage and flowering im very happy with results would highly recmmoend NPK 20-20-20
Have used this fertiliser on all my indoor plants and the results have been great. Everything’s looking healthy, lush, and growing more consistently. I’ve got a mix of pothos, ferns and calatheas. It’s clean, easy to use, and hasn’t caused any buildup or leaf burn. Definitely noticed better colour and stronger growth since switching over along with having no fishy odour smell

FAQ
Yes! It’s 100% water-soluble and great for hydro systems. Just mix as directed and apply via reservoir or manual feed.
Absolutely — just apply at half strength during cooler parts of the day to avoid leaf burn and maximise uptake.
Some listings inflate numbers — we show total nutrient analysis and use only high-quality, traceable ingredients. No fillers, no fluff.
Apply every 7 to 14 days. For sensitive plants like orchids, use a lower dose. It’s versatile and easy to adjust.
