Hydroponic towers vs aeroponic towers
Aeroponics is a branch of hydroponics and involves watering plant roots in an air or mist environment. Each of these towers is considered a low-pressure aeroponic system (LPA).
What to grow first in a hydroponic tower
Start with leafy greens and herbs: lettuces, kale, basil, cilantro, parsley, chard, and similar crops. Then, once you understand spacing and harvest cadence, expand into larger or fruiting crops with pruning and support.
