Borne from the sea.
For the discerning craftsman.

Reiziger Root Booster has the reassurance of being used by many professional gardeners and growers for over 20 years to activate, revive and stimulate indoor hydroponic plants, outdoor plants, seedlings, trees, flowers, bulbs, natives and more. This nutrient-rich, organic root stimulator has the power to save, revive or help newly potted plants and transplants, grow early white healthy roots, give more uniformity and improve survivability resulting in greener, vigorous plant growth and abundant new flowers.

Powerful. Pure. Bioactive.

This kelp is harvested sustainably from the coldest and cleanest tidal waters, its essence distilled and fermented gently with the simplest and purest natural ingredients. It’s the distillation that that makes the difference between a good organic root stimulant and a small sensation, originating from the age-old art of fermentation. The resulting highly potent broth, rich in bioactive stimulants and B vitamins, has the ability to produce astonishing results. In a brief time, roots become healthy, nutrient uptake is improved and plant growth rates and yields are maximised.
