Fox Farm

Dry salts, by the gram.

American powders rather than liquids - Open Sesame, Beastie Bloomz and Cha Ching, one for each part of the cycle - plus Big Bloom, a liquid guano and worm casting extract that can run all the way through.

Nothing matches all of those filters.

Fox Farm — the classic American trio

Fox Farm's three-bottle system — Grow Big, Tiger Bloom and Big Bloom — has been a staple in the US market for decades and works across both soil and hydro, which is fairly unusual since most ranges split their formula by medium. Grow Big handles vegetative growth, Tiger Bloom carries the plant through flower with a higher phosphorus ratio, and Big Bloom is a milder all-purpose feed that can be used throughout the cycle alongside the other two.

The trio is designed to be used together as a complete schedule rather than picked apart — Tiger Bloom without Big Bloom's micronutrient support, for instance, can leave gaps that a fuller system would cover. It's a simpler three-bottle approach compared to brands with a dozen or more specialist additives, which suits growers who want a proven, well-documented schedule without assembling it themselves from separate boosters.

Fox Farm works in both soil and hydro without reformulating between the two, unlike most brands on this site that split base feeds by medium — worth knowing if you switch mediums between grows and don't want to relearn a new schedule each time.
