Carolina Reaper
Capsicum chinense
Also known asHP22B · Smokin' Ed's Carolina Reaper
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 | 2 |
| flowering | 1 | 2 | 3 | 2.6 |
| fruiting | 1 | 2 | 3 | 2.8 |
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
A specialty crop for hot sauce makers and chile enthusiasts. EC 2.0-3.5 mS/cm. pH 5.5-6.5. Temperature: 24–32°C (C. chinense demands sustained warmth; growth stalls below 18°C). Very high light (DLI 20-30 mol/m2/day). Long season: 90-120+ days from transplant to ripe fruit. The plants are medium-sized (60–90 cm) and benefit from staking. Dutch bucket or large container systems work best. Hand-pollination improves fruit set indoors. Calcium supplementation prevents blossom end rot. Caution during handling: wear nitrile gloves when harvesting and processing. The capsaicin oil is potent enough to cause skin burns and respiratory distress if you touch your face or inhale fumes from cooking. Each plant produces 20-40 fruits over a season. The superhot peppers are primarily used for hot sauce production, dried pepper flakes, and pepper powder. A few plants provide enough product for a year of personal hot sauce making. The extreme heat means a little goes a very long way. For commercial hot sauce makers, hydroponic Carolina Reapers provide a consistent, controlled supply of the headline ingredient. Not a crop for casual growers or households with small children.
