The fourth-gen Gardyn packs a 30-plant hydroponic garden into about two square feet of floor space. No soil, no sunny windowsill required: built-in LEDs run sunrise and sunset modes, and the redesigned columns are engineered for easier cleaning with water-level monitoring built in. Seed-filled yCubes keep planting tidy, and two cameras send plant photos to the app. An optional $39-a-month Kelby AI membership uses those images and sensor readings to adjust growing schedules and send care reminders, and adds Vacation Mode plus monthly plant credits, though the basic controls work without a subscription. If you are already growing indoor plants and want to graduate from pots on a shelf, it runs $899, with $100 off using code KELBY100.
