Even in apartments or living situations where a full garden wasn’t feasible, I’ve always triedto growsomething, whether it’s a single rosemary plant on a windowsill, aTopsy Turvy Tomato, or a few basil sprigs in an old-schoolAeroGarden.For the past year, I’ve been testing various indoor smart garden systems in my home, including models from all the well-known brands, and I have some thoughts. These gardens are definitely an investment in both time and maintenance, and they’re all different in terms of what they offer. TheGardyn Home 4.0 ($899), for example, offers total success with no green thumb required if you pay for a subscription, while theAuk Mini ($259) is the perfect attractive-yet-low-maintenance solution for those who just want herbs. Are these gardens worth it? How much can you really grow? How can you be sure which option is best for your specific lifestyle?

Flowers, kohlrabi, thyme, and even a whole cauliflower all thrived in this pipe-based system with the lights in front to allow for taller plant growth.Seeds arrive in proprietary pods called yCubes. Part of what makes the Gardyn foolproof is the subscription app add-on, “Kelby,” which monitors your plants via attached sensors and cameras. It delivers customized watering and lighting schedules, as well as maintenance suggestions via AI (which an anonymous source told me is basically OpenAI’s ChatGPT with an overlaid prompt). This subscription adds an additional$259 a yearto the base purchase price, though it includes a certain number of credits per month, depending on whether you have the Home or Studio model, with which tobuy new yCubes. There’s a free 30-day trial for Kelby, but you can use the Gardyn without it by relying on manual light and watering controls. Also, there have been some recent privacy concerns with Kelby (more below).Each Gardyn purchase comes with your choice of yCube sets: “Salad Lover,” “Budding Florist,” or “Chef Faves.” I’ve tried both “Budding Florist” and “Chef Faves,” and my favorite is the latter; it has an interesting variety of everything from breen and Tokyo bekana greens to Thai basil and miniature sunflowers. Though Gardyn recommends starting the yCubes in the company’s add-on$80 nursery, I’ve germinated plenty of yCubes right in the system just fine. (Make sure you don’t add nutrients until they sprout. If you’re germinating yCubes later on, when nutrients are already in the system, you can just use a shallow bowl with loosely tented plastic wrap.) The seeds arrive tucked inmineral wool, snug in their little yCubes that slot into larger cups (“yPods”) that fit into the pipes. When the Gardyn waters the plants, the yPods fill with nutrient-infused water, and the plants’ roots grow right into the water.Once a month, the base needs to be emptied and scrubbed. Every few weeks, the ro
