Terra Aquatica Calcium Magnesium – Cal-Mag Supplement
£12.99
Type: Mineral
Mineral feeds are dissolved minerals your plant can use straight away. They're fast-acting and precise, but it is possible to overdo them, so stick to the dose.
The Two Minerals Everybody Forgets
Soft water, RO water, coco and LED lights all leave plants short of calcium and magnesium. Calcium Magnesium from Terra Aquatica puts them back, preventing the rusty spots and interveinal yellowing that come with deficiency.
Why It Works
- Calcium: strong cell walls and new growth
- Magnesium: the heart of chlorophyll for green leaves
- Ideal for soft water: RO, rainwater and coco
For Houseplant & Garden Growers
Watering with rainwater or a filter jug? A little cal-mag keeps houseplants green.
For Growers
- When: throughout the grow on soft water, coco or under LEDs
- Dose: follow the Terra Aquatica feed chart
Rose's Pro-Tip: Add products to your water one at a time and stir between each. Never mix concentrates neat.
