No. In fact, most of these hydroponic garden systems were specifically designed to be low-maintenance. Many have apps, telling you exactly when to add water, fertilizer, and other needed adjustments. The biggest thing you’ll have to do for most is to keep it watered (often only once a week but some as infrequently as once per month). Some systems may require the occasional change of bulbs, but most use long-lasting LED lights. It's a good idea to wash out the system every year, or whenever you completely change out all the plants.
