Aeroponics vs hydroponics, which should a beginner choose for greens?

For a beginner growing greens, hydroponics is almost always the better choice over aeroponics. Hydroponics is cheaper to set up, more forgiving because plants sit in or near a water and nutrient reservoir that buffers short power or pump interruptions, and there is far more local knowledge, training and vendor support for it. Aeroponics offers some advantages in oxygenation and water use for specialised cases, but it demands precise misting, redundant power, and constant maintenance, and a brief failure can kill exposed roots, which makes it a poor place to learn. Start with a simple hydroponic system, ideally NFT or substrate culture, master EC, pH, climate and disease control, secure your market, and only consider aeroponics later if you find a specific high value reason for it. The skill you build in hydroponics transfers, and the lower cost means a first-year mistake hurts less. Talk to a working hydroponic grower and your KVK before buying any system.
