Description

Veg+Bloom DOS Part A and Part B are a two-part, high-performance nutrient system designed to provide your plants with all the essential macro and micronutrients they need for healthy growth and abundant yields.

Part A contains a balanced blend of nitrogen, phosphorus, and potassium, along with other essential macronutrients and trace minerals. These nutrients work together to support vigorous vegetative growth, root development, and overall plant health.

Part B contains a carefully calibrated mix of minerals and trace elements that complement and enhance the effects of Part A. It contains higher levels of phosphorus and potassium than Part A to support optimal flower formation and fruit production, as well as additional micronutrients like iron, zinc, and manganese that are essential for healthy plant growth.

When used together, Veg+Bloom DOS Part A and Part B provide a comprehensive nutrient solution that meets the demands of your plants throughout their entire lifecycle, from seedling to harvest. Whether you're growing in soil, coco coir, or hydroponic systems, Veg+Bloom DOS is a reliable and effective way to give your plants the nutrients they need to thrive.
