Get Cuttings and Transplants Rooted and Growing Without the Setback
Superthrive Essential Vitamin Solution is a highly concentrated vitamin B1 and kelp-based plant supplement that supports healthy root development, reduces transplant shock and improves overall plant vigour. It is not a complete fertiliser - it works alongside your normal feeding programme to help plants recover from stress and keep growing strongly. Suitable for hydroponics, coco, soil and other systems, it earns its place from seedling right through to flowering.
Key Benefits
- Stronger roots: supports healthy root development and vigorous top growth
- Less transplant shock: helps plants settle quickly after potting on or moving
- Better nutrient uptake: improves feeding efficiency when run with your base nutrient
- All-media, all-stage: suitable for hydro, soil and coco through veg and flower
- Stress recovery: helps plants bounce back from pruning, root disturbance and environmental stress
- Non-toxic formula: built on vitamin B1 and kelp extract, safe for indoor grow tents and grow rooms
Just transplanted, taken cuttings or dealing with stressed plants?
Plants routinely stall after transplanting, throw weak root systems or struggle to shrug off environmental stress. Superthrive minimises these setbacks by feeding root development and encouraging tougher, more resilient growth. Used with your normal nutrient programme it helps plants establish faster, hold strong nutrient uptake and stay vigorous across the whole cycle - especially useful after transplanting, taking cuttings or any period of stress.
How to Use
- Fill your watering can or reservoir with fresh water.
- Add your normal base nutrients if required.
- Add Superthrive at 1/4 teaspoon (approx. 1.25 ml) per 4.5 litres (1 UK gallon) for routine use.
- Mix thoroughly before feeding.
- Apply during watering, or when transplanting to reduce shock.
- Continue through veg and flower alongside your regular fertiliser - it is a supplement, not a base nutrient replacement.
