Description
Hesi Bloom Complex is a liquid fertiliser specially designed for plants grown in soil, during their flowering phase. Hesi’s soil nutrient range can be used with any soil, but we recommend using a light mix such as Plagron or Biobizz, as the combination of lightly fertilised soil and additional nutrients will give you a greater level of control.
With a balanced blend of essential minerals, trace elements, and added vitamins, Hesi Bloom Complex promotes healthy growth, boosts plant metabolism, and enhances flower development without overloading your soil with salts or residues.
Key benefits of Hesi Bloom Complex:
-
Optimised for flowering – Supplies the perfect base NPK ratio and micronutrients to support abundant, healthy blooms. The addition of Hesi Phosphorus Plus or another PK booster as the flowering phase progresses will further enhance your results.
-
Enriched with vital trace elements – Includes iron, magnesium, calcium and other key elements in chelated form for easy plant absorption.
-
Boosts energy and metabolism – Fortified with amino acids, vitamins (B1, B2, B6) and sugars that support plant vitality during bloom.
-
Gentle on soil – Low salt content ensures no root burn and keeps soil structure intact.
-
Easy to use – Fully water-soluble and compatible with all soil-based grow systems. All products in the Hesi range are colour-coded with an easy-to-follow Hesi Soil Grow Schedule, making it an ideal solution for inexperienced growers and experts alike.
Perfect for indoor and outdoor growers looking to maximise flower production with minimal fuss. Use from the start of the flowering stage until harvest for best results.

Questions

Any soil works. We recommend a light mix, because a lightly fertilised soil with nutrients added by you gives a greater level of control.
Do I need a PK booster as well?
It is not essential, but adding Hesi Phosphorus Plus or another PK booster as flowering goes on will improve the results.
