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 adventurous hydroponic growers interested in pre-Columbian Mexican foods. EC 1.5-2.5 mS/cm. pH 6.0-7.5. Temperature: 18–28°C. Moderate to high light (DLI 14-22 mol/m2/day). Media beds or large containers (the plants are tall). From seed to flower cluster harvest: 70-90 days. Harvest the flower clusters when buds are tight and dark green, before any tiny flowers open. The clusters are removed from the woody central stem and typically prepared by blanching briefly, then battering and frying, or by sauteing with garlic and chile. The leaves are also edible (cook like spinach). Seeds are available from Mexican seed suppliers and some specialty heirloom seed companies. The plant grows vigorously in warm conditions and is relatively pest-free. For growers who want to explore authentic Mexican cuisine beyond the standard peppers-and-tomatoes, huauzontle is a unique crop with deep cultural significance.
