Plagron Terra Grow 1l
Plagron Terra Grow 1 litre is a mineral base nutrient engineered for the vegetative phase of soil-grown plants. This concentrated liquid fertiliser delivers an NPK ratio of 2.6-1.1-3.1 supplemented with magnesium, sulphur and six essential trace elements. All nutrients are available in mineral form for immediate root uptake without microbial conversion. The result is accelerated vegetative development and precise control over feeding parameters. Terra Grow is compatible with every irrigation system without clogging risk. The 1 litre bottle suits growers maintaining multiple plants who require consistent nutrition cycle after cycle. Experience the precision of mineral feeding.
Plagron Terra Grow 1L – Mineral Base Nutrient for the Growth Phase
Plagron Terra Grow is a highly concentrated, fully mineral fertiliser formulated specifically for the vegetative stage of plants cultivated in soil-based substrates. Unlike organic nutrient lines, there is no dependency on microbial activity for nutrient conversion — all elements are absorbed directly through the root system. This enables faster plant response and tighter control over nutrient balance. The 1 litre bottle is sized for growers managing several plants who want a reliable supply without frequent reordering.

Key features
Terra Grow provides a comprehensive spectrum of macro and micronutrients that cover the full requirements of the vegetative phase.
- NPK ratio 2.6-1.1-3.1 with predominantly nitrate nitrogen for efficient uptake and rapid cell division
- Includes magnesium and sulphur as secondary elements, plus six trace elements including iron, manganese and zinc
- Mineral composition prevents pipe fouling — suitable for drip systems, ebb-and-flow and manual watering
Application & dosage
Shake the bottle thoroughly before use. Add a maximum of 5 ml Terra Grow per litre of water (1:200) and apply this solution at every irrigation during the growth phase. A prepared solution remains viable for up to four days; however, monitor pH closely as it may rise gradually. Target a pH range of 5.5–6.5. For acute deficiencies, Terra Grow can also be applied as a foliar feed at a maximum of 2 ml per litre. Combine with other products from the Plagron range to build a complete feeding schedule.
Grower benefits
Terra Grow streamlines feeding with its single-part formula — no complex mixing of A and B components. The mineral base delivers predictable EC values and fast plant response. Nitrogen content stands at 2.6%, with the majority present as nitrate nitrogen, the most efficient form for cell division and chlorophyll production. The outcome is sturdy stems, vigorous foliage and a solid foundation for the flowering phase. For a complete package covering the entire cycle, consider the Plagron Pack XL Terra.
Combinations & alternatives
Terra Grow pairs with Plagron Terra Bloom to form the core duo for a full soil-based growth cycle. Add Power Roots during the vegetative stage to strengthen root development. Once flowering begins, switch to Terra Bloom, optionally supplemented with Green Sensation as a bloom booster. For coco or hydroponic setups, choose the dedicated Plagron lines instead.

What is the difference between Plagron Terra Grow and Alga Grow?
Terra Grow is a mineral fertiliser whose nutrients are absorbed directly by the roots without requiring microbial conversion. Alga Grow is an organic fertiliser derived from seaweed that relies on soil life for nutrient processing. Mineral nutrition acts faster and provides tighter EC control, while organic nutrition supports long-term soil biology.
Can Terra Grow be applied as a foliar feed during deficiencies?
Yes. Because Terra Grow is mineral-based, nutrients are also absorbed directly through the leaf surface. Apply at a maximum rate of 2 ml per litre of water and spray evenly across the foliage. This method is particularly effective for rapidly correcting nitrogen or trace element deficiencies during the growth phase.
How long does a prepared Terra Grow solution remain usable?
A mixed solution of Terra Grow and water remains stable for up to four days. Monitor the pH regularly as it may increase gradually during storage. Keep the solution in a cool, dark location and avoid adding organic products, as these can degrade within 48 hours in the mix.
Should I monitor pH and EC when using Terra Grow in soil?
Monitoring both pH and EC is strongly recommended. Terra Grow partially self-adjusts these values, but tap water composition varies by region. Aim for a pH between 5.5 and 6.5. The optimal EC value depends on plant species and growth stage — refer to the Plagron grow schedule for precise targets.
