Aleppo pepper
Capsicum annuum
Also known asHalaby pepper · Pul biber (Turkish) · Maraş biber (Turkish for the related Maraş pepper)
Environment
The bounded range this crop tolerates. Strict on light; outside the DLI band, yields drop sharply.

Growing media
| Medium | pH effect | Retention | Bacterial surface |
|---|---|---|---|
| Expanded clay pebbles (LECA) | neutral / inert | low | high |
| Coco coir (Coconut coir) | slightly acidic | high | moderate |

| 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
Grows well in hydroponic systems under warm, sunny conditions. EC 2.0-3.0 mS/cm. pH 5.8-6.5. Temperature: 21–30°C. Full sun or strong supplemental light (DLI 20-25 mol/m2/day). Plants are medium-sized (60–90 cm) and benefit from staking. Fruiting: 80-100 days from transplant. The peppers are primarily used dried, so post-harvest processing matters: slice fruits in half, remove seeds, and dry in a dehydrator at 55–65°C or in sun for several days. Crush the dried halves into flakes. A small amount of olive oil mixed in during crushing replicates the traditional oily texture. Calcium supplementation prevents blossom end rot. Increase potassium during fruiting. In hydroponic greenhouses, Aleppo pepper performs similarly to other medium-hot C. annuum varieties (comparable culture to Anaheim or Hungarian wax). The plants are perennial in frost-free conditions. Surplus production of dried Aleppo flakes stores for 12+ months in sealed containers. A rewarding crop for growers who cook Mediterranean or Middle Eastern food. The flavor profile of properly dried Aleppo pepper is complex: fruity, mildly sweet, moderately hot, with a slightly oily, raisin-like quality that distinguishes it from generic red pepper flakes. Growing and processing your own ensures authenticity, which matters because much commercial Aleppo pepper has been adulterated or substituted with other dried chiles since the Syrian civil war disrupted traditional supply chains.
