What NPK 20-20-20 Means

A balanced, all-purpose fertilizer—also called 20-20-20 fertilizer or 20 20 20 fertilizer—supplying equal parts nitrogen (N), phosphorus (P) and potassium (K) for even vegetative growth, strong roots and steady flowering across vegetables, houseplants, ornamentals and lawns.

Balanced nutrition: Equal N-P-K (20-20-20) supports leafy growth (N), rooting & bud set (P), and vigor & stress tolerance (K).
All-purpose use: Great “all purpose fertilizer” for seedlings, transplants, herbs, greens, houseplants and ornamentals—ideal between bloom-booster cycles.
Flexible formats: Works as a water-soluble powder or a ready-to-mix 20 20 20 fertilizer liquid for soil, coco or hydroponics.

What is NPK 20 20 20? It’s a complete, balanced plant food delivering 20% nitrogen (for chlorophyll and foliage), 20% available phosphate (P₂O₅ for roots and blooms) and 20% soluble potash (K₂O for quality, color and resilience). Because the ratio is even, this 20-20-20 fertilizer is a reliable “do-most-things” feed that keeps growth steady without pushing plants too hard in any single direction.

Use for vegetables, flowers, shrubs, lawns and indoor plants when a general, balanced feed is desired.
Mix as directed by your product label; apply to moist media for consistent uptake. Can be used as a foliar spray where appropriate.
If your water is very soft or plants are heavy feeders, pair with a calcium-magnesium supplement for complete nutrition.

My chain of hearts have been giving me plenty of seeds lately so I thought I would have a go at growing some in Sphagnum Moss under grow lights and feeding them with @completegrow…. 9 weeks later I have healthy little babies 😍 @time__and__place.

Been using this fertiliser in my hydro setup and the results have been very good. The lettuce is growing fast, full, and super vibrant. I like that it’s clean and doesnt stink, mixes easily, and works without clogging anything. Has made a big difference from the last fertiliser i used.
