Essentials PLUS NO STRESS is designed to improve plant health and aid stress tolerance. Whether your plant is being affected by heat, drought, cold or pests this additive will provide support. Used alongside regular nutrients, NO STRESS helps your plant manage environmental stress, cope with reduced amounts of water but still produce great yields. NO STRESS contains a natural source of carbon, potassium, nitrogen, fulvic acids, magnesium, sulphate and carefully selected trace elements, all of which are in demand by plants during times of stress. Potassium is very important for photosynthesis, osmoregulation and stomatal movement, therefore vital during stressful periods.
