Did you know plants need the same balanced "diet" of vitamins and minerals as we do? Feeding your hydroponic plants with the proper nutrients is crucial to your indoor garden's livelihood. The right nutrients are essential to help your plants grow successfully with maximum yields. Hydroponic growers have to determine what their garden needs depending on their plants, but many seeds will begin with the same macronutrients.
Your unique nutrient solution provides the food your seeds need to grow and bloom. Each type of nutrient blend can have a different effect on every stage of growth, so we offer a wide range of options. You can browse our selection for anything from conditioners to supplements and see the difference they make.
At HTG Supply, we have premium nutrients for hydroponic gardens made by industry-leading brands that you know and trust. We also carry nutrients for all stages of plant development, so you can be sure there is a solution for every application.
Advantages of Hydroponic Nutrients in Your Garden
Plants need to feed on more than air, water and light. Adding nutrients to your reservoir or water supply will give your seeds the minerals soil usually provides — and more. One of the most critical parts of feeding your grow room and expanding your harvest is creating a nutrient solution.
Here are a few benefits of using various hydroponic nutrients in your grow room:
- Increased growth: Certain enhancers or supplements can both improve your plants' growth and quicken the process. The beneficial vitamins, bacteria and minerals can work wonders on your garden's progress.
- Ingredient management: Many experienced growers make compost teas or nutrient solutions based on their system's needs. Your ability to control what your seeds absorb creates healthier plants and stronger results.
- Necessary minerals: With hydroponics, your plants need to get their nutrients from somewhere. The absence of soil creates a need for essential minerals like calcium and nitrogen. Most growers use several nutrients, conditioners and enhancers for best results.
- Pest control: Many hydroponic nutrients are made to build tolerance to pests and plant diseases. A concentrated nutrient solution including these additives in your reservoir can help to prevent damage from bugs, algae, mold and disease so you can grow effectively. Plus, a soilless system already attracts fewer pests and invasive species.
- Plant health and strength: In certain stages, you can add supplements or enhancers for stronger roots, thicker cell walls and better blooms. These are powerful additions to your nutrient solution and can drastically improve your final product.
Our Soil & Hydroponic Nutrients for Sale
Hydroponic gardeners may choose different nutrients for each growth stage. You can learn more here about what each hydroponic nutrient can do for your garden.

We carry brands such as Advanced Nutrients, General Organics, Down to Earth and other leading nutrient manufacturers.
- Base nutrients: Base nutrients include potassium, phosphorous, nitrogen and micronutrients that are vital to growing healthy, high-yielding plants. We sell one-, two- and three-part base nutrients to meet all your requirements.
- Conditioners: This class of nutrients adjusts soil states and reservoirs for better nutrient absorption, soil health and clean systems. Our conditioner products include humic and fulvic, pH down and pH up, enzymes, mycorrhizae and beneficial bacteria.
- Supplements: Growers feed supplements to plants to maintain their health and correct soil deficiencies and nutrient schedules. Our selection of supplements includes foliar sprays, calcium magnesium, amino acids and vitamins, seaweeds and kelps, silica and organic supplements.
