Nutrient lines we recommend for soil, coco, and hydro — base trios, powder systems, and cal-mag supplements.
Full breakdown of N-P-K, pH, EC, soil vs coco vs hydro, and how to build a feeding schedule.
Three-part liquid base used in soil, coco, and hydro. Industry standard for precise control over N-P-K through each growth stage.
Best for
All-around growers who want one system for veg and flower
Why we recommend it
Flexible, well-documented feeding charts, and easy to scale from a single plant to a full tent. Works in every common medium when pH is managed.
Organic-friendly liquid trio tuned for soil and soilless mixes. Big Bloom adds microbes and humic acids throughout the run.
Best for
Soil growers who prefer a simple liquid schedule
Why we recommend it
Forgiving in soil, widely available, and pairs naturally with Fox Farm or similar peat-based mixes without over-complicating feeding.
Lower-nitrogen hydro/coco version of the Fox Farm trio. Designed for frequent irrigation and inert mediums.
Best for
Coco and hydro growers who like Fox Farm's approach
Why we recommend it
Solid coco/hydro alternative to GH Flora with a similar three-bottle workflow and strong community track record.
Three-part base with built-in pH buffers. Reduces daily pH adjustment in many water profiles.
Best for
Growers who struggle with pH stability in soilless systems
Why we recommend it
Helpful when pH drift is your biggest headache. Follow label rates — the buffered formula is less forgiving of over-feeding than it feels.
Powder-based three-part system: 5-12-26, calcium nitrate, and magnesium sulfate. Mix fresh batches per reservoir or watering.
Best for
Budget-conscious coco and hydro growers comfortable with a scale
Why we recommend it
Extremely cost-effective at scale, stable when stored dry, and favored by experienced coco/hydro growers for consistent results.
Calcium, magnesium, and iron supplement. Essential add-on for coco, RO water, and LED-heavy grows.
Best for
Coco, RO water, or any grow showing calcium/magnesium deficiency
Why we recommend it
Coco binds calcium aggressively; RO strips minerals from tap. Cal-mag prevents the classic new-growth yellowing that base nutrients alone won't fix.
Calcium and magnesium supplement from the same line as Flora. Low N, easy to add alongside any base nutrient program.
Best for
Flora users and anyone needing a reliable cal-mag backup
Why we recommend it
Pairs cleanly with Flora Trio and most liquid programs. Keep a bottle on hand even in soil if you use soft water or heavy coco blends.
