Features: Up to 30 plants | Free accompanying app | 6-gallon water tank

Complete with an artificial intelligence-based assistant app, this five-foot vertical gardening system debuted at the 2021 Consumer Electronics Show. Gardyn can grow up to 30 plants simultaneously using integrated LED lighting, sensors, and a six-gallon water reservoir that is fully autonomous for weeks without added water. The free app lets you see more details about your plants, including when a crop is ready to be harvested or your plants’ temperature, humidity, and water levels.

This indoor smart garden also has a vacation mode to preserve your plants when you are away, and you can even remotely check in on them in the app through Gardyn’s embedded vision system. Gardyn lets you grow greens, herbs, fruits, veggies, and flowers, all with minimal effort on your end since the AI tech takes care of your plants for you.

Features: 3 plants at a time | Autonomous watering | USDA-certified organic greens 

If you’re strictly interested in the world of microgreens, the Ingarden is a great indoor smart garden option that also looks super sleek in your kitchen. This indoor smart garden uses autonomous watering complete with a ventilation system and wicking structure so you can easily grow microgreens. Simply place the included pads onto the growing beds, pour water over, hold the light timer at the top for three seconds, and get fresh microgreens about a week later.

Ingarden offers various USDA-certified organic superfood microgreens such as arugula, cress, radish, etc. You can grow up to three pads of microgreens at a time.

Features: 7 plant pods | 5-liter water tank | 24W LED lights

Those looking to get into indoor smart gardens but don’t want to spend a lot should consider the iDOO Hydroponics Growing System. It’s the cheapest option on this list, but it still has seven plant pods so that you can harvest many different plants at once.

Some of its features include 24W LED lights that simulate sunlight spectrum, two water pump modes and a five-liter water tank, and three light modes depending on the stage of your plants’ growth. It also has an adjustable light height so the light moves with your plants as they grow taller.

Features: 6 plant spaces | Automatic reminders | Adjustable arm lamp

Perhaps one of the most recognizable brands in the indoor smart garden space, Aerogarden has plenty of smart garden planters to begin your indoor garden. The Harvest Elite is a compact option that still allows six plants to grow. As your plants grow, its extendable lap arm gets up to 12 inches tall to allow more room.

The planter itself has automatic reminders for water and food, so you never have to guess when your plants need something. A big plus about Aerogarden is its Grow Anything Kits that allow you to put any seed you want into its seed pod, meaning you get more options with what you grow rather than only a specific selection of seeds to choose from.

Features: 3 plant spaces | Automatic lighting cycle | Smart Soil pods 

The Click & Grow indoor smart garden 3 is your best bet if you have a small space to work with. At 9 x 4.9 x 12.5 inches, it’s the most compact option on our list but still holds three plants of your choosing. You can choose from more than 50 plant refill capsules, including peppers, chives, catnip, yellow tomatoes, and more. Click & Grow’s plants contain a patented nano-material called Smart Soil that automatically releases oxygen and water to your plants and is inspired by NASA technology.

The device’s lamp has a 16 hours on/8 hours off cycle to optimize your plants’ growth. In addition, its water float indicator will let you know when it’s time to refill the tank. And, since there is no water pump, the Click & Grow is completely silent.
