Plant Magic Soil Grow — Mineral-Based Vegetative Nutrients for UK Water
Best for: Soil growers wanting a straightforward, UK-formulated mineral feed that handles hard or soft water without fuss
Our thoughts
Plant Magic Soil Grow sits in that sensible middle ground—proper mineral-based nutrients formulated specifically for UK water chemistry, without the premium price tag of the big Dutch names. It does what soil growers actually need: deliver calcium, magnesium, and trace elements in ratios that work, regardless of whether you're in a hard or soft water area. One we recommend a lot for soil cultivators who want to stop guessing and start feeding properly.
Plant Magic Soil Grow is a liquid mineral-based nutrient concentrate designed for the vegetative stage of soil growing. It contains magnesium, calcium, humates, and trace elements balanced specifically for UK water conditions—available in both hard and soft water formulations. This matters. Most generic nutrients don't account for regional water chemistry, which means you're either under-feeding or creating lockout. Plant Magic does the thinking for you, letting your soil microfauna adjust pH naturally and your plants absorb what they actually need.
How it compares
Sits firmly in the mid-tier mineral-based nutrient segment for UK soil growers.
- Mineral-based, so more precise nutrient control than organic options like BioBizz
- UK water-optimised formulation—BioBizz and Dutch brands don't account for regional hardness variations
- Significantly cheaper than premium systems like CANNA or Advanced Nutrients
- British-made with local grower support, unlike imported alternatives
In practical terms: you're getting proper soil grow nutrients at a price that leaves room in the budget for other essentials, formulated to actually work with your tap water.
Usage guidance
Plant Magic Soil Grow is designed for the vegetative stage through to the end of week one of bloom:
Dosage
Apply at 2–3ml per litre of water. Follow your feeding schedule or apply when soil nutrients begin to deplete.
Application through veg
Feed every watering or every other watering depending on your soil quality and pot size. Start at 2ml/L and adjust based on plant response.
Water management in soil
Soil should sit at roughly 25% water content. If it looks waterlogged, drain excess immediately—you'll drown the roots otherwise. Let it dry to roughly 50% between feeds.
Hard or soft water selection
Choose the version that matches your tap water. If you're unsure, check your local water authority report or test a sample. Using the wrong formulation wastes money and creates unnecessary pH swings.
