From Humboldt County Roots to Global Growth

Born in the heart of Humboldt County, California, FoxFarm began as a small, family-run company with a revolutionary idea — that soil should be alive, not sterilized.

Four decades later, that same passion drives every bag and bottle they produce. Each mix is carefully crafted in small batches, using premium ingredients and real grower testing to ensure consistent results for every crop, every time.

Hydrobuilder proudly partners with FoxFarm to bring growers living soils, balanced nutrients, and legendary reliability — all backed by decades of proven performance.

Happy Frog®

Your potted plants deserve the best. Their roots can’t seek out nutrition in the ground, so you have to bring it to them. That’s why Happy Frog® Potting Soil is amended with soil microbes that can help improve root efficiency and encourage nutrient uptake.

Between the earthworm castings, bat guano, and aged forest products, your container plants have never felt so good.

Happy Frog® Potting Soil is designed for container planting.

Frequently Asked Questions

A: We recommend feeding your plants up to twice a week, ensuring that they receive a regular watering in-between feedings. When feeding and watering your plants, you will want to apply enough water or solution so that 10-15% runs out the bottom of the container. Once the top 2-3” of media have dried out, it is time to water again.

Grow Big® Hydro (3-2-6) is formulated with a form of nitrogen that is better taken up by the plants in a hydroponic system. With that in mind, we do not recommend using the soil formulation of Grow Big® (6-4-4) in your hydroponic system.

A: Potting soils are formulated using specific ingredients that meet the needs of plants grown in container gardens. The perlite in FoxFarm potting soils creates air spaces in the soil that facilitate drainage, while peat moss retains moisture in a container environment, enabling you to water less often. Planting mixes and soil conditioners are designed for raised beds and in-ground planting. These products break up compacted soils and work well as a mulch top-dressing.

A: Using FoxFarm fertilizers with products made by other companies could result in burning or nutrient lockout. For best results we recommend that you Keep the Tribe Together®. Our products are designed to work together and complement one another, and our research and development team has created feeding schedules for a variety of growing environments. These feeding schedules will give you clear instructions about how and when to use FoxFarm fertilizers together for outstanding results.

A: These products are not intended to be used at the same time. They are developed for different stages of the flowering process. Please refer to our FoxFarm Feeding Schedules for more detailed instructions.

A: When you mix FoxFarm fertilizers together, do not combine them in their undiluted form. Begin with a gallon of clean water. Add each fertilizer product to this gallon of water in the recommended doses. If growing in soil, adjust the pH of your nutrient solution to between 5.6 and 6.8, and if growing hydroponically, adjust your pH to between 5.8 – 6.3. For best results follow one of our FoxFarm Feeding Schedules.

A: Big Bloom®, Grow Big®, Grow Big® Hydro, and Tiger Bloom®. Use at the recommended rates of application for supplemental foliar feeding on the back label of these products.
