Ecothrive Soil Food Grow 5kg is a premium organic top-dress soil amendment formulated specifically for vigorous vegetative growth in living soil. With a typical NPK analysis of 3.5-3-4.5, it combines readily assimilable nitrogen with phosphorus, potassium, calcium, magnesium, sulphur and amino acids to replenish nutrients as plants build roots, stems and healthy foliage.
Soil Food Grow is part of Ecothrive's complete Soil Food system and is designed around a simple living soil principle: replace the nutrients plants have used rather than continuously feeding them with soluble fertiliser.
The key ingredient is soy amino hydrolysate, which provides fast-acting organic amine nitrogen. Ecothrive selected this highly accessible form of nitrogen to support strong vegetative development while stimulating the biological processes responsible for nutrient cycling within living soil.
Mealworm frass, micronised rock phosphate, potassium sulphate and gypsum complement the nitrogen source, creating a balanced top-dress containing both immediately useful and medium-release nutrition.
Soil Food Grow is particularly useful for fast-growing or heavy-feeding plants that begin to draw down the original nutrient reserves in their living soil during the vegetative stage.

Balanced organic nutrition for vegetative growth
Vegetative plants need sufficient nitrogen to construct new foliage, proteins and chlorophyll, but successful growth requires more than nitrogen alone.
Soil Food Grow provides a balanced blend of macro and secondary nutrients with a typical analysis of:
-
Nitrogen (N): 3.5%
-
Phosphorus pentoxide (P₂O₅): 3%, equivalent to approximately 1.3% elemental phosphorus
-
Potassium oxide (K₂O): 4.5%, equivalent to approximately 3.8% elemental potassium
-
Calcium: 6%
-
Magnesium: 1%
-
Sulphur: 4%
-
Amino acids: 6%
The result is a vegetative top-dress designed to replenish the nutrients that an actively growing plant removes from its soil while maintaining a balanced living soil system.
Soy amino hydrolysate - fast-acting organic nitrogen
The key ingredient in Soil Food Grow is soy amino hydrolysate, a fast-acting organic source of amine nitrogen.
Nitrogen is fundamental to vegetative growth, but different organic nitrogen sources become available at different rates. Ecothrive uses soy amino hydrolysate because its amine nitrogen is readily assimilable, helping plants access useful nitrogen without waiting exclusively for slower organic materials to break down.
This makes it particularly valuable when established plants begin placing greater demand on the original nutrient reserve in their living soil.
The formulation balances this relatively fast response with medium-release inputs, helping provide useful vegetative nutrition while reducing the risk of unnecessarily accumulating large quantities of residual nutrients.
Feed the plant while supporting living soil biology
Soil Food Grow is designed to work with the biological processes that make living soil function.
Organic nutrients are transformed and cycled by microorganisms within the root zone. Ecothrive's formulation is designed to encourage this biological activity rather than bypass it with a conventional high-strength soluble mineral feed.
The soy amino hydrolysate provides accessible organic nitrogen, while Ecothrive Charge mealworm frass contributes organic material that supports microbial life and nutrient cycling.
Maintaining an active soil ecosystem helps organic nutrient sources become part of a continuing cycle between soil, microorganisms and plant roots.

How to use Ecothrive Soil Food Grow
Soil Food Grow is designed to be top-dressed periodically during vegetative growth.
For established indoor plants, use 1-2g per litre of soil. Calculate the dose using the volume of soil within approximately the top 15cm of the pot or bed.
Spread the measured amendment evenly over the soil surface, lightly scratch it into the top 2-4cm and water after application.
For established plants in approximately 40-60L pots, Ecothrive recommends applying Soil Food Grow during the late vegetative or early transition stage, approximately 3-4 weeks after planting.
Smaller containers generally deplete their nutrient reserves more quickly than larger containers and living soil beds, so application should always be adjusted according to plant demand, container volume and growing conditions.
When should Soil Food Grow be applied?
Ecothrive's Soil Food system is designed around plant demand rather than a rigid weekly fertiliser schedule.
Soil Food Grow is intended for the vegetative phase, when plants are actively producing roots, stems, shoots and foliage.
As a general guide, Ecothrive suggests using Grow around 3-4 weeks after planting in smaller pots or 4-6 weeks in larger pots. For established 40-60L containers, application during late vegetative growth or early transition is recommended.
These timings should be treated as guidance rather than an automatic feeding date. Plant size, crop duration, soil volume, environmental intensity and previous soil use all affect nutrient demand.
Using Soil Food Grow outdoors
Soil Food Grow can also be used as an organic top-dress for established outdoor crops grown in field or garden soil.
Apply 100-200g per m², spread evenly across the soil surface.
Lightly scratch the amendment into the top 2-4cm of soil and water after application.
For established outdoor crops, Ecothrive recommends repeating the application approximately every 4-6 weeks, adjusting according to plant performance and growing conditions.
Grow, Bloom & Re-Gen - the Ecothrive Soil Food system
Soil Food Grow is one part of Ecothrive's three-stage organic powdered nutrient system for living soil.
Soil Food Grow
Use during vegetative growth to replenish nitrogen and balanced nutrition required for strong roots, stems and foliage.
Soil Food Bloom
Switch to Soil Food Bloom as plants enter flowering or fruiting. Its formulation reduces nitrogen and increases phosphorus and potassium to better match generative plant demand.
Soil Food Re-Gen
After harvest, use Soil Food Re-Gen to restore depleted living soil and prepare it for another crop.
The products are designed to be used sequentially according to crop stage, rather than applying all three together.
Designed specifically for Ecothrive Living Soil
Ecothrive Living Soil contains an initial reserve of nutrition, so newly planted crops do not automatically need additional fertiliser.
As plants grow, however, those nutrient reserves are gradually consumed. Heavy-feeding plants, smaller soil volumes and high-intensity growing environments can accelerate this depletion.
Soil Food Grow is designed to replenish the nutrients used during vegetative development without abandoning the living soil approach.
Rather than feeding on a fixed liquid nutrient schedule, the aim is to top up the soil when plant demand indicates that additional nutrition is required.
How much soil will a 5kg bag treat?
At the recommended indoor rate of 1-2g per litre of soil, a 5kg bag provides substantial coverage for multiple containers or large living soil beds.
At 1g/L, 5kg provides enough Soil Food Grow for approximately 5,000 litres of calculated soil volume.
At 2g/L, it provides enough for approximately 2,500 litres.
Remember that Ecothrive recommends calculating indoor top-dress quantities using the soil volume within approximately the top 15cm of the pot or bed rather than automatically using the entire container volume.
For outdoor applications at 100-200g/m², a 5kg bag provides approximately 25-50m² of coverage per application.
