Banana pepper
Capsicum annuum
Also known asYellow wax pepper · Hungarian wax (hot variants) · Banana wax 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
One of the easiest and most productive pepper varieties for hydroponic growing. EC 2.0-2.8 mS/cm. pH 5.8-6.5. Temperature: 20–28°C. Moderate to high light (DLI 18-25 mol/m2/day). The compact plant size works well in DWC, NFT, and Dutch bucket systems. Plants begin producing fruit 60-75 days from transplant and continue for months. Each plant can yield 25-40 peppers over a season under hydroponic conditions. Harvest at the yellow stage for the mild, classic banana pepper flavor, or let them ripen to red for slightly sweeter flavor. The thin walls make them ideal for pickling: slice into rings, quick-pickle in vinegar with garlic and spices, and they're ready in 24 hours. For stuffing, harvest slightly larger fruits and fill with cream cheese or sausage filling. Calcium supplementation prevents blossom end rot. The plants are light feeders compared to larger pepper varieties. Pest pressure is low in indoor systems. Banana peppers are a reliable, high-yield crop for beginners, producing usable quantities of fruit within two months of transplanting.
