Growers Ark are a UK based (Sheffield) company, who produce high-quality plant food and additives. In order to give their customers the best possible products, they only use technical grade salts in their food. The biological components of their food are of an equally high quality (from sustainable resources) and where possible from organic sources. The mixture of minerals in their food is picked to give the best results for plant growth rather than the easiest / cheapest mix to manufacture. Growers Ark manufactures and bottles all of their products in-house, and do not contract out the production or bottling of any of their products.
