Ferro do something unusual: they formulate their base feeds for specific regional water supplies, so a Greater London grower is not fighting the same hardness a soft-water grower never has to think about.
The range covers Growth and Bloom A-B for soil and hydro, Coco Growth and Bloom, Osmosis versions for RO water, plus Bio Roots, Bio Crops, Enzyme Plus, PK Bloom Booster and Oxy Org.
