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. Hold EC around 2.0-3.0 mS/cm and pH 5.8-6.5. It demands sustained warmth, 2432°C, with growth stalling below 18°C, and very high light, 25-35 mol/m2/day. The season is long, well over 110 days from transplant to ripe fruit. Plants are medium, 6090 cm, and benefit from staking, and Dutch bucket or large containers suit them; hand pollination improves set indoors, and steady calcium prevents blossom end rot. Handle with care: wear nitrile gloves to harvest and process, because the capsaicin oil can burn skin and cause respiratory distress if it reaches your face or you inhale cooking fumes. Each plant gives 20 to 40 fruits, used mostly for hot sauce, flakes and powder, where a little goes a very long way. This is not a crop for casual growers or households with small children.
