Review: Reliable, well know brand - 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.
Review: GREAT basic, all-purpose plant food for hydroponics - 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>
