Read our full verification: Is FoxFarm Made in USA?Est. 1984

Born in Humboldt County
FoxFarm was founded in the early 1980s in Humboldt County, California — the region of the northern California coast known for its ancient redwood forests, clean Pacific air, and intensive small-scale agriculture. The company's founders drew on the knowledge base of Humboldt County's agricultural community to develop soil and fertilizer formulations that addressed the specific needs of container gardening and intensive cultivation.
The company has remained in Humboldt County, with production facilities in Arcata, throughout its four decades of operation. The California origin is more than geographic: the state's agricultural innovation infrastructure, organic certification programs, and demanding environmental standards have shaped the company's product development and manufacturing practices.
Ocean Forest: A Premium Blend
Ocean Forest potting soil is FoxFarm's flagship product, a rich organic blend designed to deliver maximum plant performance without additional fertilization for the first several weeks of use. The formula combines aged forest products and sphagnum peat moss for water retention and soil structure with a marine-derived nutrient package: fish meal, crab meal, shrimp meal, oyster shell, and earthworm castings.
The marine ingredients are what distinguish Ocean Forest from competitor premium potting mixes. Fish meal and crab meal provide a complex nitrogen source that releases slowly as microorganisms break down the proteins, feeding plants over time rather than delivering a front-loaded nutrient spike. The oyster shell adds calcium and natural pH buffering. Earthworm castings introduce beneficial microorganisms and plant-available humic compounds. The resulting pH of 6.3-6.8 sits in the optimal range for most vegetable and ornamental plants.
Liquid Nutrients for Every Stage
FoxFarm's liquid nutrient trio — Big Bloom, Grow Big, and Tiger Bloom — addresses the three major stages of plant growth. Grow Big is a high-nitrogen formula for vegetative growth: building leaf area, root systems, and stem structure. Tiger Bloom is a high-phosphorus formula for flowering and fruiting: signaling reproductive effort and supporting fruit development. Big Bloom is a low-analysis microbial fertilizer that supports beneficial root zone biology and enhances nutrient uptake throughout all growth stages.
Using the three products together creates a nutrient program that supports plants from seedling through harvest without the over-fertilization or deficiency problems that single-formula feeding programs produce. The trio's formulation reflects decades of field testing and refinement in Humboldt County's intensive cultivation environment.
