Stimulate root growth with VitaLink RootStim. This additive uses high quality seaweed extracts with natural bio-stimulant properties and hormones to encourage plant roots to grow long, strong and healthy. By using this product in the early stages of plant life, it helps to encourage rapid root growth but it can also be used at any stage of the plant life cycle at a reduced dosage to improve roots.

RootStim can be used in hydroponic systems, coco coir media and soil. We recommend you use 1ml per 1L for the first week of vegetation, you would then use 0.5ml per 1L right up until bloom week 7
