Description
Thicker, Faster Roots From Cutting Through to Bloom
British Minerals Root Mass is a root stimulator built on essential minerals, natural plant extracts, vitamins and trace elements including microalgae. The microalgae fraction is the interesting part - it supplies both nutrients and natural growth hormones, which is what produces noticeably thicker and more balanced rooting rather than simply more of it.
It also contains substances that help a plant ride out environmental stress such as drought or temperature extremes, so it earns its place well beyond the propagation bench. The active ingredients have been shown to significantly increase rooting speed and final biomass in independent studies at international universities. Used on cuttings and transplants it speeds establishment; applied as a foliar spray it helps stressed plants recover.
Key Benefits
- Considerably speeds up root development for thicker, more balanced rooting
- Microalgae, vitamins and trace elements supply nutrients and natural growth hormones
- Independently verified to increase rooting speed and final biomass at international universities
- Helps plants overcome stress from drought and temperature extremes
- Works as a foliar spray to bring stressed plants back
- Reduces reliance on synthetic fertilisers and pesticides by building a healthier root system
Transplant Shock and Slow Establishment
The week a cutting or a young plant spends sitting still after being moved is dead time you never get back, and it usually comes down to a root system that has not yet found the new medium. Pre-treating that medium and feeding growth hormones and trace elements straight to the root zone shortens the gap dramatically. Carrying a low maintenance dose through bloom then keeps the root mass working at the point the plant is asking most of it.
How to Use
- Shake well before use
- Cuttings, transplants and vegetative growth (weeks 1-4): 4ml per litre of water
- Flowering (weeks 5 onward): reduce to 0.5-1ml per litre
- Re-potting: pre-treat the growing medium with the solution before the plant goes in
- Foliar: spray the formula onto the leaves to help a stressed plant recover
- Check reservoir pH after adding - Root Mass may raise it slightly
- Do not exceed the recommended dosage
