Capsicum annuum
Also known as: Hungarian wax pepper, Magyar wax, Erős paprika (Hungarian)
Quick facts
- Category
- fruiting
- Difficulty
- beginner
- Days to harvest
- 65 to 80 days
- Harvest type
- continuous production over weeks or months
- Spacing
- 50 cm between plants
Environment
- Temperature
- 18–30°C
- pH
- 6 to 6.8
- EC (hydroponic)
- 1.8 to 2.6 mS/cm
- Daily light
- 20 to 28 mol/m²/day (strict, will fail outside this range)
Climate and zones
- USDA zones
- 4 to 12 (winter low around -34°C or warmer)
- Frost tolerance
- frost sensitive (dies at first frost)
- Season
- warm (summer crops, frost-sensitive)
Viable growing environments:
- outdoor in growing season (annual)
- unheated greenhouse / hoop house
- heated greenhouse
- indoor (heated home)
- indoor hydroponics under grow lights
USDA zone bounds reflect outdoor year-round survival. Anywhere outside the bounded zone range, this crop still grows as an annual in the warm months (outdoor_seasonal), under cover (greenhouse), or indoors under lights.
Growing systems
Hungarian Hot Wax works in:
- drip / Dutch buckets
- media bed (ebb and flow)
- soil bed
Growing media
The substrate the roots sit in. Choice depends on the system (clay pebbles don't fit NFT channels; rockwool isn't used in media beds) and the crop (hungarian hot wax works in the media listed below).
| Medium | pH effect | Water 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 by source | high | high |
Bacterial surface area matters for aquaponics: clay pebbles, lava rock, and pumice double as biofilter substrate. Low-surface media (rockwool, perlite, pea gravel) work in hydroponics but need a separate biofilter in aquaponics.
Nutrient demand by stage
NPK ratios are relative weights at each growth stage; the nutrient mix calculator scales them to absolute grams or ml. EC targets shift through the plant's life: seedlings need a much lighter solution than fruiting adults.
| Stage | N | P | K | EC target (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. Plan around this in shared reservoirs.
Aquaponics suitability
Compatible with typical aquaponics nutrient profiles. 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 reliable, early-maturing hydroponic pepper. EC 2.0-2.8 mS/cm. pH 5.8-6.5. Temperature: 18–28°C (one of the more cold-tolerant peppers; produces well at temperatures that slow many other varieties). Moderate to high light (DLI 16-22 mol/m2/day). Plants are compact (40–60 cm). From transplant to first harvest: 60-70 days (one of the fastest peppers from transplant to fruit). Each plant produces 15-25 peppers. Harvest at the yellow stage for pickling (the classic use) or at red for a sweeter, hotter product. For pickling: pack whole or sliced peppers into jars with garlic, vinegar brine, and spices. The thick walls produce a satisfying crunch in pickled rings. Calcium supplementation during fruiting prevents blossom end rot. The early maturity makes Hungarian hot wax peppers a good choice for northern hydroponic growers with limited growing seasons or for greenhouse production where fast turnover is important.
