Plagron Nutrients - Terra Grow - Mineral Base Nutrient for Soil, Grow Phase
Best for: soil growers who need a straightforward, mineral base nutrient for the vegetative growth stage.
Our thoughts
This is a base nutrient in the true sense - it covers what your plant needs during vegetative growth, no more, no less. Terra Grow is built for soil growing specifically, and it's designed to sit comfortably alongside Plagron's own additives if you want to build out the feeding schedule later. Straightforward, reliable feeding without overcomplicating the grow stage.
Plagron Terra Grow is a highly concentrated mineral base nutrient formulated for the growth phase of plants grown in soil, with an NPK ratio of roughly 3-1-3, weighted toward nitrogen and potassium to support strong stem and leaf development. It's quickly absorbed, giving plants the nutrition they need to build a solid vegetative structure before moving into flower.
It's suitable for use with all soil mixes and is designed to work alongside other liquid fertilisers and additives, including Plagron's own bloom and booster range, so it slots in easily whether you're running a minimal feeding schedule or a fuller one.
How it compares
Mineral base nutrients for soil growing are a crowded category, and Terra Grow competes on being a straightforward, no-frills option rather than a boosted "complete" formula.
- Compared with Canna Terra Vega, both are mineral base nutrients built for the vegetative stage in soil, with dosing rate and bottle pricing being the main practical differences.
- Compared with BioBizz Bio Grow, an organic alternative, Terra Grow gives more predictable, fast-acting feeding since it's mineral rather than microbially dependent.
- Compared with a "complete" all-in-one feed, Terra Grow is a base nutrient only - you'll want to add boosters and additives separately if you want to push beyond basic feeding.
It's a dependable, no-nonsense base nutrient - exactly what you want underpinning a soil grow before you start layering on extras.
Usage guidance
Terra Grow is used throughout the vegetative stage, with the dose scaled to plant size.
Dosing
Use approximately 2.5-5ml per litre of water, adjusting up or down depending on the size and feeding demand of your plants.
Feeding schedule
Apply with regular waterings during the vegetative stage, switching to a dedicated bloom nutrient once you move plants into flower.
Combining with additives
Works alongside root stimulators, silicon additives and other Plagron products without needing to adjust the base dose significantly.
