Bird's eye chile
Capsicum frutescens
Also known asAfrican bird pepper · Piri piri · Pili pili · Cabe rawit (Indonesia) · Siling labuyo (Philippines)
Environment
The bounded range this crop tolerates. Strict on light; outside the DLI band, yields drop sharply.

Growing systems
Root mass: moderate.
Growing media
| Medium | pH effect | Retention | Bacterial surface |
|---|---|---|---|
| Expanded clay pebbles (LECA) | neutral / inert | low | high |
| Coco coir (Coconut coir) | slightly acidic | high | moderate |
| Perlite (Expanded volcanic glass) | neutral / inert | very low | low |
| Rockwool (Mineral wool) | alkaline until pre-soaked | very high | low |
| Soil-based mix (Potting soil) | varies | high | high |
Nutrient demand by stage
NPK ratios are relative weights. EC targets shift through the plant's life.
| Stage | N | P | K | EC (mS/cm) |
|---|---|---|---|---|
| seedling | 2 | 1 | 1 | 1.2 |
| vegetative | 3 | 1 | 2 | 1.8 |
| flowering | 1 | 2 | 3 | 2.2 |
| fruiting | 1 | 2 | 3 | 2.4 |
Companion-growing notes
- Heavy uptake of potassium, calcium. Co-grown crops with the same demand will end up deficient even at "correct" EC.
Aquaponics suitability
Compatible
Fish waste provides enough nitrogen for healthy growth. Supplemental potassium, calcium, and iron may still be needed depending on fish stocking density.
Care notes
One of the most productive and compact pepper varieties for small hydroponic systems. EC 2.0-3.0 mS/cm. pH 5.8-6.5. Temperature: 24–32°C (tropical origin; needs sustained warmth for best production). High light (DLI 18-25 mol/m2/day). The small plant size makes bird's eye chiles excellent for countertop, windowsill, or vertical hydroponic growing where space is limited. Plants begin fruiting 70-90 days from transplant and continue prolifically for months. Each plant can produce 100-200+ small fruits over a season. Harvest when fruits are green (milder, sharper flavor) or red (hotter, slightly fruity). The plants are perennial in warm conditions and can fruit continuously for 2+ years. Pest pressure is low; the capsaicin in the fruits deters many insects. The upright fruit position makes harvest easy. For cooks who use a lot of Southeast Asian chiles, 2-3 plants in a small hydroponic setup provide a year-round supply. The tiny fruits dry well: thread on string and hang to air-dry, or use a dehydrator at 55°C.
