CompleteGrow All Purpose Liquid Fertiliser

Houseplants

A great liquid fertiliser for indoor plants, especially for growers who want a clean, easy routine for pots, foliage plants and popular houseplants like Monstera, pothos and peace lilies.

Veggies

Excellent for vegetables and herbs where growers want stronger growth, healthier leaves and better overall performance through the growing season.

Flowers

A balanced option for flowering plants, ornamentals and garden beds when you want steady feeding instead of switching between multiple products.

Lawns

Useful as an all purpose lawn fertiliser for gardeners wanting quick colour response, greener growth and a simple liquid feeding option.

Hydroponics

Suitable for growers searching for a hydroponic liquid fertiliser that can be used as part of a flexible feeding program.

What NPK 20-20-20 Means

NPK 20-20-20 means this fertiliser contains equal proportions of nitrogen, phosphorus and potassium. This balanced ratio is one of the reasons 20-20-20 fertiliser is so widely used across many plant categories. Nitrogen supports leafy green growth, phosphorus helps root development and early establishment, and potassium contributes to plant strength, stress tolerance and overall performance.

Because the ratio is balanced, it works especially well as an all purpose fertiliser for gardeners who do not want separate feeds for every plant. It suits general maintenance feeding, active growth periods, and a wide variety of indoor and outdoor uses.

Why This Liquid Fertiliser Works For So Many Plants

A good all purpose liquid fertiliser needs to do more than just provide nitrogen. It needs to support leaves, roots and general plant health at the same time. That is why a balanced liquid feed with micronutrients is so useful for mixed gardens, indoor collections, edible crops and general landscaping.

This formula is especially helpful for gardeners searching for one product they can use across houseplants, vegetables, herbs, flowering plants, orchids, lawns and hydroponic systems. Instead of trying to match a different fertiliser to every single plant, this gives a broad-coverage feeding option that is practical, effective and easy to use week after week.

Perfect For These Growing Goals

Instead of a generic all-purpose feed, show shoppers exactly why this fertiliser suits their plant type. This helps people instantly think, “yes, this is for me.”
