Extremely vigorous plant. MUST be containerised within a dedicated grow bed to prevent system-wide colonisation. High inulin can cause digestive discomfort if eaten in large quantities.
Very resilient and productive, ideal for steady harvest cycles
Extremely fast-growing; ideal for nutrient uptake and system balancing
Requires significant space and planning
Very uniform growth
Hardy alternative to watercress
Requires excellent drainage
Requires patience and stable conditions

Very fast-growing and productive
Very fast and productive
Adds strong flavour to mixes
Thrives in lower nutrient systems
Heat-tolerant spinach alternative
Good for continuous harvest
Adds colour to systems
Excellent Andean staple crop. Day-length sensitive — tubers form as days shorten. Contains oxalic acid (less after cooking).
Thrives in heat; highly productive in warm systems
Can work with excellent aeration; best suited to large, stable systems
Most are mild, some are hot. SHU: 500–2,500
Reliable and easy

Larger fruit needs stable feeding. SHU: 1,000–2,000
Prefers drier root conditions than typical aquaponics
Performs surprisingly well in highly aerated media and aeroponic systems. KEY RISK: seed potato rot — in media bed trials the seed tuber rots and degrades water quality. Solution: use a wet vacuum to remove the seed potato once plants are established but before the seed perishes. NASA has successfully grown potatoes in aeroponic systems for decades.
