Aji dulce
Capsicum chinense
Also known asAji cachucha · Cachucha pepper · Aji gustoso · Sweet habanero
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
Well-suited to indoor hydroponic growing due to compact plant size. EC 2.0-2.8 mS/cm. pH 5.5-6.5. Temperature: 22–32°C (C. chinense species prefer heat; growth stalls below 18°C and frost kills the plants). Full sun or strong supplemental light (DLI 18-25 mol/m2/day). The compact habit works well in DWC, Dutch bucket, or NFT systems. Fruits are small (3–5 cm) and produced prolifically on well-fed plants. Harvest when fully colored (90-110 days from transplant). Calcium and magnesium supplementation prevents blossom end rot and yellowing. The plants are perennial in warm conditions and continue producing for 2+ years if kept above 15°C. Good airflow prevents fungal issues. Aji dulce is an excellent choice for hydroponic growers who want the distinctive habanero-family aroma in cooking without the extreme heat. The compact plants and prolific fruiting make it one of the more practical pepper varieties for small indoor systems. The sweet-but-aromatic chinense flavor profile is unique and cannot be replicated with C. annuum sweet peppers. This makes aji dulce valuable for cooks who want the habanero family aroma in dishes without any significant heat. In Caribbean cooking, aji dulce is used in sofrito (the base for rice, beans, and stews) and in pepper sauce. The plants produce 50-100+ small fruits over a season, providing abundant supply for kitchen use.
