Fox Farm Big Bloom Liquid Plant Nutrient Fertiliser for Hydroponics & Soil

Big Bloom by Fox Farm is a micro-brewed organic liquid nutrient suitable for use throughout the entire plant life cycle. Formulated with earthworm castings, bat and seabird guano, rock phosphate, sulphate of potash magnesia, and Norwegian kelp, it delivers a full range of organic nutrients and trace elements that support overall plant health, root development, and flower and fruit quality. Compatible with both soil and hydroponic systems.

NPK 0.01-0.3-0.7

Derived from: earthworm castings, bat and seabird guano, rock phosphate, sulphate of potash magnesia, and Norwegian kelp. The low NPK reflects its role as an organic supplement rather than a primary feed — it works alongside base nutrients to enhance plant health and improve the quality of flowers, fruits, and herbs.

How to Use

Because Big Bloom is fully organic, it is gentle enough to use with every watering throughout the growth cycle. For plants showing signs of stress, a root drench application can help restore vigour. Ideal for flowering and fruiting plants at all stages.

Breathable Lid Notice

Fox Farm uses breathable lids on all liquid products. There is no inner seal — a small hole in the bottle cap allows live microbes to breathe. This is intentional and does not affect product quality.
