HGV Nutrients -- Premium Plant Nutrients for Indoor Growing
HGV is Hydrobuilder's own premium nutrient brand, developed by the cultivation team at Hydrobuilder Holdings with a focus on high-performance indoor and CEA growing. HGV products are formulated using pharmaceutical-grade chelated mineral inputs for consistent bioavailability across a range of growing media and system types -- the same quality tier used by premium third-party nutrient brands, at pricing that reflects Hydrobuilder's direct-to-grower model without distribution margin. HGV nutrients are developed and tested in active production environments, informed by feedback from the commercial growers, CEA operators, and cultivation specialists that make up Hydrobuilder's customer and expert network.
HGV Base Nutrients
HGV's base nutrient line provides a complete two-part program covering both vegetative and flowering stages -- formulated to deliver accurate, consistent EC contribution in coco coir, rockwool, perlite, and recirculating hydroponic systems. The two-part A and B format separates nutrients that cannot coexist in concentrated form (primarily calcium from phosphates and sulfates) to prevent precipitation in the concentrated stock solution. Fully dissolve each part separately before combining in the reservoir, following the mixing order specified on the label. HGV base nutrients are designed to work as a complete standalone program or alongside qualified Cal-Mag supplements for RO water and coco coir programs. Free shipping.
HGV Supplements & Additives
HGV produces a range of performance supplements designed to stack on top of the base program -- silica for structural strength, bloom-phase PK supplements for peak flowering, and bio-stimulant additives for root zone health and nutrient uptake efficiency. All HGV supplement formulations are developed around the base nutrient ratios to avoid nutrient antagonism when running the full program. For growers new to HGV or building a first complete nutrient program alongside pH and EC meters, the base nutrients plus Cal-Mag plus silica is the recommended starting configuration -- the full supplement stack can be added progressively as experience with the base program develops.

HGV Nutrients FAQ
What makes HGV nutrients different from other brands?
HGV is formulated by Hydrobuilder's own cultivation team using pharmaceutical-grade chelated mineral inputs -- the same quality tier as premium brands like Athena and Emerald Harvest, at a price point that reflects Hydrobuilder's direct-to-grower supply chain without distributor margin. Being developed by a team that works directly with commercial CEA growers and cultivation specialists means HGV formulations are informed by real production feedback rather than developed in isolation. For growers who want a high-quality nutrient program without paying third-party brand premiums, HGV is the direct alternative.
Does HGV come with a feeding schedule?
Yes -- HGV nutrients include a recommended feeding schedule covering vegetative growth, early flower, peak flower, and late flower/flush phases with specific dosing rates for each stage. Start at the low end of the recommended range for the first cycle and adjust based on plant response and EC meter readings. Like any nutrient program, target EC and plant health indicators should guide your actual application rates rather than the schedule alone -- use it as a starting framework and dial in from there.
Can I use HGV nutrients in any hydroponic system?
Yes -- HGV base nutrients are formulated for compatibility across coco coir, rockwool, perlite, recirculating DWC/RDWC, and drain-to-waste drip systems. The clean, fully chelated formulation stays in solution well in recirculating systems and does not produce the sediment or precipitate issues that can affect lower-quality nutrient programs in long-run RDWC configurations. For soil or heavily buffered living soil programs, a soil-specific nutrient approach may be more appropriate than a hydroponics-optimized program like HGV.
Do I need Cal-Mag with HGV nutrients?
If you are using RO or soft water, or growing in coco coir, yes -- add a dedicated Cal-Mag supplement. HGV base nutrients provide calcium and magnesium in their formulation, but RO water strips Ca and Mg from the base solution composition, and coco coir actively buffers calcium from nutrient solution until saturated. In these scenarios, supplemental Cal-Mag at 2-4 ml/gallon before base nutrients provides the additional Ca and Mg needed to meet plant requirements. With moderately hard tap water (150-300 ppm TDS), the tap water's Ca and Mg content may be sufficient alongside the base nutrients without additional supplementation.
Is there free shipping on HGV nutrients?
Yes -- all HGV Nutrients products ship free to every state. Free shipping is included automatically at checkout for the full HGV product line with no minimum order requirement.
