Grow Big Hydroponic Plant Food - 3-2-6 Liquid Plant Fertilizer for Lush Vegetative Growth in Hydroponic Systems - Liquid Concentrate with Earthworm Castings & Micronutrients - 1 Pint

This fertilizer is amazing for hydroponic systems! My plants grew stronger, greener, and healthier after just a few uses. The 3-2-6 formula with micro-nutrients really supports vegetative growth, flowering, and fruiting. I also love that it’s pH adjustable, which makes it easy to customize for different plants. Feels high-quality, works as promised, and gives my garden a noticeable boost. Highly recommend for serious plant lovers!

I’ve had a really good experience using FoxFarm hydroponics products. They’re easy to use, well-labeled, and produce consistent results. My plants responded quickly, showing healthy growth and strong development. I appreciate the quality of the ingredients and how versatile the products are—they work well in hydroponic systems and can also be adapted for other growing setups. While they’re a bit more expensive than basic nutrients, the results make them worth it. Overall, FoxFarm is a trusted brand that delivers dependable performance, and I’d definitely continue using their hydroponics products.

When the plant food that came with my hydroponic system ran out, I had a hard time deciding what kind to get. The FoxFarm products stood out to me, both because I'd seen them in my local HEB, and because they are derived from real ingredients. I know people will say synthetic fertilizers are the same, but I'm not sure. They are also potent enough they are easy to do, and maybe I'm just not as much a stickler for reading directions as I should be. The NPK on the Grow Big fertilizer looks just right for most plants you want to grow hydroponically, and it worked quite well when I added it following their directions. (2-3 t per gallon of water). I do need to get a conductivity or ppm meter to better gauge my water quality, especially as I am using tap water that contains minerals. But for now I'm doing OK>

Seems to be greatly appreciated, need to use cal mag with this, separate flowering mix available

This organic fertilizer seems to work very well

I’ve been using FoxFarm Grow Big Hydro for my hydroponic plants, and I’m very pleased with the results. This liquid fertilizer provides a full spectrum of micro-nutrients, which helps promote strong vegetative growth, flowering, and fruiting. I’ve noticed a significant improvement in the overall health and size of my plants since I started using it. What I particularly appreciate about Grow Big Hydro is its ability to be pH adjusted without causing any nutrient lock-up, which is a big concern when using liquid fertilizers. The formula is easy to mix and apply, and it delivers consistent, high-quality results. My plants are thriving, and they seem more robust than before. At 16 ounces, the pint bottle offers excellent value for the price. It’s a great size for regular use and lasts for quite a while, making it a practical choice for hydroponic growers. If you're looking for a reliable, high-quality nutrient solution for your hydroponic garden, FoxFarm Grow Big Hydro is definitely worth trying!

Great organic fertilizer.

I started using this for all my plants whether they grown in water or dirt. The results have been amazing, especially those plants that are required regular feeding

I can’t honestly say this made a difference for my plants
