Bloom Activator and Leaf Fertilizer Hesi Boost 500 ml

For the flowering stage of plant development. This new product strengthens the flowering, increases the sugar content and improves the condition of the entire plant. Suitable for use in all forms of growing medium (Soil, Coco and Hydro). Hesi Boost is not nutrient specific and can be used with all nutrients, although for best results we recommend using in conjunction with the Hesi range of nutrients. Hesi Boost has a low nutritional value and does not replace the normal nutrient solution. The plant will have an increased need for water after Hesi Boost has been added; the extra metabolic processes that are activated need water as additional fuel for fruit production. Do not use in conjunction with aggressive chemicals such as Peroxide as this will destroy the natural enzymes and other natural active ingredients.
