Black Currant (Ribes nigrum) in Hydroponics
The Black Currant is a flowering shrub native to central and northern Europe and northern Asia. It bears small black berries that are rich in vitamins, particularly vitamin C, and are commonly used in jams, jellies, and beverages. This plant thrives in well-drained soils and is increasingly cultivated using hydroponic systems due to its adaptability and high yield potential.

Propagation Methods
- Cuttings: Take semi-hardwood cuttings in late summer, ensure 2-3 nodes are present. Place in moist soil or water until roots develop.
- Seeds: Harvest seeds from fully ripe fruit, clean and dry them. Plant in moist soil, germination takes 2-3 weeks, transplanting after 6 weeks.
- Other methods: Layering can be used; bend a lower branch to the soil to encourage rooting.
Stages of Growth
After propagation, Black Currant plants typically take about 70-100 days to reach maturity for harvest. This involves:
- Propagation (0-2 weeks)
- Root development (2-4 weeks)
- Vegetative growth (2-4 weeks)
- Flowering and fruiting (3-6 weeks)
- Harvesting (70-100 days total)
From a single seed, you can expect approximately 500-2000 grams of fruit when fully mature.
Common Pests
- Aphids
- Spider mites
- Leafhoppers
- Powdery mildew (fungal infection)
