Shop By Popular Supplements
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.

Why HGV Nutrients?
HGV is built for commercial growers who demand more from their plants — more aroma, more flavor, and higher yields at scale. Blended entirely in our own facility for unmatched quality and consistency, our formulas deliver clean, reliable nutrition that drives terpene production and maximizes genetic potential.
What is HGV Dry?
HGV Dry is the foundation of the HGV nutrition system — a trusted product relied on by commercial growers for years to deliver uncompromising quality and top-tier yields. Developed for efficiency and performance, these dry formulas meet the demands of large cultivation environments while keeping input costs low.
HGV Dry also offers the added benefit of reduced shipping costs compared to the liquid format. Whether you use HGV in dry or liquid form, it consistently delivers high-quality results without compromise.

HGV Base Formula
HGV Part B supplies essential Calcium and Nitrogen to boost plant structure, metabolism, and growth across all stages. It ensures consistent nutrient uptake for strong, healthy development.

HGV Grow Formula
HGV Grow Formula boosts vegetative growth, promoting foliage expansion and uniform canopy. It supports root and shoot development, laying a strong foundation for flowering when paired with HGV Part B.

HGV Flower Formula
HGV Flower Formula delivers targeted P, K, S, and key micronutrients to support flower development and terpene production. Designed for the generative phase, it works with Part B to maximize resin, structure, and yeild.
What is HGV Liquid?
HGV Liquid is the latest evolution of HGV, designed for growers who want the convenience of a liquid nutrient without compromising the quality and yield potential HGV is known for. It features the exact same formula as our Dry line — just in a pre-mixed, liquid form.
The Liquid line makes it easier than ever to feed plants with precision—whether you're a home grower or managing a large commercial facility. HGV Liquid delivers plug-and-play simplicity: pure performance, no shortcuts.
Shop Water Soluble Fertilizers
Water-soluble fertilizers are designed to dissolve in water, allowing them to be applied directly to plants via drip irrigation and foliar application, which enhances nutrient use efficiency.
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.
