Fish-based nitrogen for fast, dark green vegetative growth
Plagron Fish Force is a fish-based plant nutrient for the growth phase, rich in nitrogen, amino acids and vitamins. It is an NPK 3-6-2 fertiliser that stimulates and accelerates growth, drives chlorophyll production for deep green leaves, and builds plants with high natural resistance. It is equally at home on mother plants, where a weekly feed keeps cuttings coming from healthy, vigorous stock. Note that Fish Force is for soil growing - it is not suitable for hydroponic systems.
Key Benefits
- NPK 3-6-2 fish-based fertiliser aimed squarely at the vegetative phase.
- Rich in nitrogen, amino acids and vitamins, the building blocks of fast leaf and stem growth.
- Stimulates chlorophyll production for darker, more efficient foliage.
- Builds high resistance against stress and pests.
- Ideal for mother plants treated weekly, keeping cutting stock in good condition.
- Simple 1:100 dilution at 10ml per litre - one rate to remember.
Slow Growth and Pale Leaves in Veg
A short veg period is where low yields usually begin. Plants that grow slowly, throw pale leaves and never fill the tent are almost always short of available nitrogen, and mother plants cut from repeatedly suffer the same way. A weekly organic nitrogen feed keeps growth moving and colour dark without pushing EC up hard, which matters in soil where salt build-up shows quickly.
How to Use
- Standard rate: shake well, then add 10ml of Fish Force per 1 litre of water (a 1:100 dilution).
- Frequency: feed this solution once a week throughout the growth phase.
- Mother plants: treat weekly at the same rate to keep stock vigorous.
- Media: for soil growing only - not suitable for hydroponic systems.
- Irrigation systems: flush the pipes after use to stop organic residues settling.
- Expect some smell: a cloudy solution or odour after mixing is a normal bacterial process from the organic ingredients and harms nothing.
- Important: despite the name, never give Fish Force to fish, ponds, aquariums or any animal - it is plant nutrition only.
