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 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 easiest, most productive peppers for hydroponics. Hold EC around 1.8-2.6 mS/cm and pH near 5.8-6.5. Run temperatures 20–28°C with moderate to high light, on the order of 20-28 mol/m2/day. The compact plants suit deep water culture, NFT and Dutch bucket. Fruit starts about 60 to 75 days from transplant and keeps coming for months, with 25 to 40 peppers per plant over a season. Pick at the yellow stage for the classic mild flavour, or let pods ripen red for a touch more sweetness. The thin walls make them ideal for pickling: slice into rings and quick-pickle in vinegar with garlic and spices, ready within a day; harvest larger fruit for stuffing with cheese or sausage. Keep calcium steady to prevent blossom end rot. These are lighter feeders than big bell or chile types, and pest pressure indoors is low, which makes them a dependable high-yield crop for beginners with usable fruit inside two months.
