Growers Ark 2 part coco base nutrient is specifically formulated for growing in coco-coir using a range of feeding methods.
It is manufactured from high grade salts and EDTA chelated trace elements for the maximum ease of uptake by the plants. It also contains extra trace elements as sulphates to provide a secondary source of traces for the plants.
Growers Ark coco food contains potassium humate (what makes part B brown), this is a large molecule of the same chemical family as humus (one of the things that makes a good soil good) Humate is highly active in soil (or any other growing medium) being involved in the uptake of nutrients by plants, microbial activity and the cycling of nutrients. Studies have shown that plants grown in a medium rich in humic substances are more resistant to stress and have bigger root systems.
