Most often a grower utilizes a pre-balanced nutrient package as the basis of the feeding schedule, but there are cases when a grower needs to further refine specific nutrients to increase vegetative growth or flowering, or to prevent or correct deficiencies.
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.

Explore our range of water-soluble fertilizers designed to support your growing needs, whether you're cultivating indoor plants or other crops. Our products offer the quality and reliability you need to achieve excellent results in your indoor or outdoor garden.
Top Water-Soluble Fertilizer Brands
Water-soluble fertilizers offer farmers the flexibility to easily adjust nutrient concentrations to meet the evolving needs of plants throughout their growth cycles. Although working with water-soluble fertilizers requires more active management, the potential for maximizing value in a shorter timeframe makes it a worthwhile effort from a professional perspective.
Shop Organic Nutrients
Organic nutrients offer the finest plant food and provide all the same NPK nutrition as synthetics. Hydrobuilder.com offers the largest selection of organic nutrients and organic nutrient packages
Unlike synthetic plant nutrients, organic nutrients come from living or "organic" sources, such as animal or plant waste. Some examples are kelp meal, or fish based fertilizer. These are renewable and ecologically stable, and growers who decide to implement an organic feeding schedule will leave a smaller footprint on the environment.
