2-Part

Grow and bloom. Veg and flower. Whatever you call it, 2-part nutrients are designed to cover both phases of plant growth with just two bottles. These kits will break down into a grow, designed to cover the vegetative growth of the plant, and flower, which is used to cover the flowering growth of the plant. Grow will generally contain a higher amount of nitrogen, whereas the bloom will have higher phosphorus and potassium. Both will contain a spectrum of micronutrients. It is common in 2-part nutrients to use both bottles at the same time, just different ratios in veg and bloom. HTG Supply carries top brands like Roots Organics, General Hydroponics, CANNA, and more! Shop now to find your next favorite nutrient.
