Shop By Veg Nutrients or Bloom Nutrients

Veg nutrients are, simply put, nutrients for veg stage of growing. They provide much higher levels of nitrogen than bloom nutrients, with lower levels of phosphorus and potassium. These three nutrients make up the NPK ratio.

The reason veg nutrients have higher levels of nitrogen is because this macronutrient is responsible for helping your plants produce branches and foliage.

Bloom nutrients are specifically used during the plants flowering stage. The main elements that make flowers bloom are potassium and phosphorus.

Base Nutrients vs Additives

Base nutrients, whether for veg or bloom, are to be used as the main part of your feeding schedule during the growth or flower stage. Additives, sometimes referred to as Growth Enhancers or Bloom Boosters go above and beyond what your base nutrients provide your plant to push out even bigger, more potent flowers.
