Product description
Plagron Coco A & B 5 L: product details and use
Plagron Coco A & B 5 L is a two-component, highly concentrated mineral base nutrient for buffered coco substrates, covering both veg and flowering. Calcium (A) and phosphorus (B) are kept in separate cans so they cannot bind and precipitate in concentrated form. The 5 L can is an economical choice for larger grow rooms and growers who run several cycles a year.

How to use
Shake well and add max. 4 ml Cocos A per litre of water (1:250), mix, then add the same amount of Cocos B. Never mix A and B undiluted. Use the solution with every watering and adjust to pH 5.5–6.5. Coco needs frequent watering to prevent salt build-up. Check pH daily and use the mixed solution within 4–10 days.
