Enjoy Gardening Year-Round With These Indoor Garden Systems (2024)

Enjoy Gardening Year-Round With These Indoor Garden Systems (1)

You don't have to wait for the outdoor growing season to have fresh herbs, vegetables, and flowers—an indoor garden system makes it possible year-round. Plus, many options take care of the watering and feeding for you, while providing enough light to keep plants happy, no matter where you place them in your home.

You can even start your seeds for your outdoor garden while it's still cold outside. “Indoor grow systems can help you get a jump start on a colorful garden by starting seed trays in February and March. Being able to experiment with a variety of seeds is a very fun project in the cold, dreary winter months,” says Melissa Lallo Johnson, a master gardener based in Kansas City, Missouri.

We tested 18 different indoor growing systems at our own homes across the country over a six-week period (over 18,000 hours and counting!). While we tested systems with and without grow lights, our testing confirmed that those with grow lights were more successful. In fact, during our separate test of grow lights, we found that the plants with grow lights grew 81 percent taller on average than those that just used natural lighting.

After setting up each system and planting the pods or seeds according to the manufacturer's instructions, we measured the growth of each plant after three and six weeks. We then evaluated each indoor garden on setup, ease of use, design, performance, quality, and value. Here are the best options for growing a successful indoor garden.

What We Like

  • Easy to set up and maintain

  • Timed grow lights and watering schedule

  • Large watering basin and plant capacity

What We Don't Like

  • Only accepts AeroGarden pods

After testing 18 different indoor garden systems, the AeroGarden Bounty Basic Indoor Garden earns our best overall spot. We initially tested this system in our lab for three months before testing it again at home. Both times, we found it to be very easy to set up and maintain and appreciated the variety of healthy, tasty herbs it provided—nine plants in total. As long as you have the counter or table space and a spot where you won't find the light to be distracting, we think this is a great option for most homes.

This hydroponic indoor garden is equipped with 30-watt LED grow lights to provide full spectrum light and promote photosynthesis, eliminating the need for natural sunlight. According to the manufacturer, plants will grow up to five times faster in this unit than they would in traditional soil. In fact, all of our herbs grew quickly: Our Genovese basil seeds sprouted first and were soon followed by the rest.

If you are new to gardening (or just want an effortless way to garden), this system makes it easy to begin. Set up took less than 15 minutes, with just a few pieces we had to snap into place, followed by plugging it in. We were slightly confused by setting up the timer for the grow lights, but the base's touch screen provided instructions to help guide us through quickly.

We love that each seed pod is marked with the expected height—short, medium, tall—so you know where to plant them in the unit (front for smaller plants, back for the taller ones). It comes with seed pods for Genovese basil, curly parsley, dill, thyme, Thai basil, mint, chives, and Italian parsley, but AeroGarden offers numerous other options as well. Note that you can only use AeroGarden seed pods with this system, however.

To accommodate plants as they grow taller, you can easily adjust the height of the light panel up to 24 inches. Plenty of other advanced features include a touchscreen control panel that displays your plant’s vital statistics and reminds you when to add water and plant food. It even estimates the days until seed germination. A timer turns the unit’s lights on and off automatically, and a large water bowl allows you to go longer between refills. It also has a vacation mode, so your plants stay nourished even when you’re out of town.

  • Very easy to set up and maintain

  • Can use AeroGarden seed pods

  • Automatic light timer and water pump

What We Don't Like

  • Light timer does not allow for alternate settings

  • Lights don't lift up very high

It might not have quite as many bells and whistles as our top pick, but this compact hydroponic system earned perfect scores during our tests. We found it very easy to set up the system and had basil sprouting in less than a week (the other herbs soon followed). The starter set includes basil, parsley, oregano, thyme, mint, cilantro, and dill seeds, but note that the system only has space for five pods at a time.

The growing system has a 2.5-liter water reservoir with a pump that automatically turns itself on for 30 minutes out of each hour to keep the water fresh and oxygenated. We were pleased with the pump's silent performance and helpful water gauge that lets you know when the reservoir needs to be refilled. We needed to top it off twice a week at first, but more frequently as the plants got bigger.

The LED grow lights have just the right balance of red and blue light to promote the best plant growth. However, there are two light settings: one for vegetables and one for flowers. The light timer does not allow the level of control that the AeroGarden Bounty Basic does, but we found it more than adequate. Its default is 16 hours of light on, and 8 hours with the light off, but you can turn it off yourself if desired.

This system doesn't require a very large space on your counter, and it's compatible with AeroGarden pods as well as inbloom's pods for more variety. Like the AeroGarden Bounty Basic system, you can raise the grow lights as your plants get taller, up to a maximum of 17.25 inches. But note that it is slightly shorter than the Bounty Basic's, 24-inch maximum light height.

Dimensions: 10.25 x 5.4 x 6.25 to 17.25 inches | Plant Capacity: 5 | System Type: Hydroponic

What was the best color light for plant growth?

While thebest color light for plant growthcan depend on the type of plant and plant stage, choosing an option with a full spectrum light that covers the full PAR (Photosynthetically Active Radiation) Spectrum, 400 to 700 nanometers, and includes plenty of red and blue light, is optimal for most uses.

What We Like

  • Compact size

  • Very simple to set up

  • Self-watering system and LED grow lights

  • Built-in timer

What We Don't Like

  • Only includes basil

  • Lights don't extend over the entire growing area

After testing the Click & Grow Smart Garden 3 for over three months in the lab and at home, we found that it's easy to use and perfect for small spaces. At less than five inches wide, this attractive indoor garden system hardly took up any space on our countertop. And despite its small size, this unit has many useful features, including energy-efficient LED grow lights, a built-in timer, and a self-watering tank to encourage optimal growth.

The LED grow lights are on a timer, which has only one setting: 16 hours on, 8 hours off. We set it to correspond with our own typical bedtime/wake time, and didn't find the light objectionable at all. One potential downside to the system is that the lights don't extend completely out to the end of the system, meaning that the pod on the far end might not get quite as much light exposure as the rest (but we haven't found any issues with this to date).

As your plants grow, this garden does come with two extension arms that we found easy to click on. That allows you to adjust the height of the grow lights up to a maximum of 19 inches. We found that handy when our basil grew too high and also burned at the top (we were surprised by how quickly the basil grew!).

The water reservoir has a small gauge that shows when the level is dropping low. According to the manufacturer, it can go a couple of weeks before needing a refill, but make sure you keep an eye on it so your plants don't get too thirsty.

The Click & Grow Smart Garden 3 includes three basil pods to get you started, a perfect ingredient for pizza, salad, and pasta recipes. We do wish it came with a variety of herbs instead of all of the same type, but you do have the option to use your own seeds (using the Grow Anything Plant Pods). or purchase additional pods from Click & Grow (over 50 plant varieties to choose from). However, due to its compact size, this indoor garden is best suited for growing herbs rather than vegetables.

Rise Gardens Personal Garden and Starter Kit

Enjoy Gardening Year-Round With These Indoor Garden Systems (14)

What We Like

  • App allows you full control over the lights

  • Comes with a starter "nursery"

  • Includes 8 different seed pods

What We Don't Like

  • Light height not adjustable

  • Must use Rise seed pod refills

Other picks on our list might cost less, but none provide all of the features and benefits of this splurge-worthy indoor gardening smart system from Rise. We found it very easy to set up—basically, we just set the trays in place, added water, and turned it on. Plus, the Rise app made maintenance a breeze—you can control the full spectrum LED lights, get reminders about when to add water and nutrients, and follow the daily reminders and helpful hints about your plants' care and growth. You can also control the system through Amazon Alexa.

Unlike other indoor gardens, this one comes with a small plant "nursery" which holds up to eight seed pods. You use the nursery to start your seed pods before transferring them a week or so later into the main garden.

The garden comes with an eight-pod starter kit that includes a variety of herbs and vegetables, including lettuce, parsley, basil, and cilantro. We are happy to report that all of our plants sprouted quickly and remained green and healthy throughout our testing session. You'll need to use Rise pods to refill your garden, but luckily, they sell a wide range of herb, vegetable, and flower pods on their website.

While not a compact system, this is also not an oversized garden, so it should be easy for most people to find a suitable space to house their growing greenery. Note that unlike most other systems, the grow lights cannot be raised or lowered, but at a height of 16 inches, they allow you to grow a wide range of plants without crowding.

What We Don't Like

  • Instructions for setup not clear

Some indoor garden systems are undeniably pricey, but there's no need to break your budget with the iDOO Hydroponics Growing System. Although this is a no-frills setup, we were very pleased with its performance and found it very easy to maintain (aside from some initial confusing setup instructions). This is a fairly compact system, so we're happy to report that it didn't take up too much room on our kitchen counter.

Unlike some other more expensive indoor gardens, this one does not come with any seeds or pods, but you can purchase any herb, flower, or vegetable seeds that you'd like, as long as you stick with varieties that do not grow taller than 15 inches, which is the maximum you can extend the grow lights. Herbs are ideal, but you can also grow lettuce or other short veggies. The system holds eight pods, but you might find your plants are crowded if you use all eight at the same time.

The grow lights have two settings: one for fruit/flowers and one for vegetables. You cannot alter the settings of the timer, which keeps the grow lights on for 16 hours after you plug in the system, and then shuts them off for 8 hours before repeating the cycle, so keep that in mind when considering placement. Although it doesn't notify you when water is needed, the water reservoir has a small window so you can see when the water is getting low and it has a small pump to keep the water circulating.

Other than the seeds, the system comes with everything you need, including fertilizer. Our seeds sprouted and grew quickly into healthy, green plants. While not the most elaborate indoor gardening system, we highly recommend this offering from iDOO for anyone who'd like to grow their own herbs without spending a bundle.

  • Helpful reminders for water and fertilizer

What We Don't Like

  • Lights are very bright at full intensity

  • Takes up quite a bit of counter space

The AeroGarden Bounty Elite offers all of the great features of our best overall pick, the AeorGarden Bounty Basic, with a few helpful extras, including smart features. Thanks to the system's WiFi or Amazon Alexa capabilities, as well as the AeroGarden app and touchscreen, you can easily set the light's timer to match the needs of the specific seeds you are planting. Plus, you can set the timer to simulate dawn/dusk, lower the intensity of the lights—something we really appreciated, because at full power they are very bright—or turn them on/off remotely. You'll also get reminders of when to add water and fertilizer, which is always helpful, even if you've been gardening for years. There's even a vacation mode to keep things humming when you are out of town.

This is one of our pricier picks, but we feel it is worth every penny for the many advanced features this indoor garden system offers, starting with the very simple setup. This large system can hold up to nine pods and comes with the Gourmet Herbs Seed Pod Kit, featuring Genovese basil (2), curly parsley, dill, thyme, Thai basil, mint, chives, and Italian parsley. However, AeroGarden offers many other seed pod options, including tomatoes, bell peppers, petunias, several types of lettuce, and a wide range of herbs.

This is a fairly large system, with adjustable height ranging up to a whopping 30 inches for growing larger vegetables. It also comes with a small trellis to help lend support to larger plants and keep them from flopping over. We found that our seeds started off quite slowly, taking more than a week to germinate, but once they sprouted, they grew quickly, and all remained green, healthy, and tasty. We even like the sleek, stainless steel design of the system, which is quite attractive on the kitchen counter.

What We Don't Like

  • Seed pads not clearly labeled

  • Can only be used with manufacturer's refills

If you love cooking with microgreens, the seedlings of various vegetables and herbs, you'll love this system from Inagarden. This sleek indoor garden is specifically designed for growing microgreens and features an attractive stainless steel frame and a handcrafted ceramic base, with four colors to choose from.

We found that maintaining the system couldn't be easier. We added water at the beginning, set the seed pads in place on their small trays, and switched on the grow light. The timer automatically keeps the lights on for 12 hours, then off for 12 hours, then back on again. The grow lights are fixed in position and cannot be raised higher, but that's not an issue with microgreens, which are eaten when they are only a few inches tall. We loved not having to deal with messy soil, a noisy pump, or even fertilizer; this is about as easy as it gets. And at less than six inches wide, the garden is slim enough to fit on a windowsill or bookshelf.

This kit includes red cabbage. radish, and mustard seed pads. However, they were not labeled, so we didn't know what they were until they grew. Luckily, we didn't have to wait long: Ingarden guarantees that the seeds will sprout within 7 days, but our seeds sprouted in just 24 hours. Within a week they were around 3 inches high and ready to eat.

Note that you can only use Ingarden's seed pads with this system. While they do offer several varieties of refill seed pads to choose from, they are rather pricey, although the price goes down if you subscribe. Still, if you like the taste and healthy nutrients provided by microgreens—we used our harvest to add flavor to salads and stew—it's hard to go wrong with this compact and stylish growing kit.

What We Like

  • Attractive appearance

  • Reminders for water and fertilizer

  • Fairly compact

What We Don't Like

  • Cannot dim grow light

This compact, six-pod indoor gardening system from AeroGarden is ideal for herbs, thanks to its maximum of 12 inches of growing height underneath the LED lights (the light arm itself extends to 18 inches). You can also use it for growing lettuce or other fairly short crops. We found it very easy to set up and maintain, and appreciated that it didn't take up too much space on our kitchen counter. Our system came with the Gourmet Herbs Seed Pod Kit, which includes Genovese basil, curly parsley, dill, thyme, Thai basil, mint, chives, and Italian parsley, but AeroGarden offers other options as well.

Like most AeroGarden systems, this one has full-spectrum grow lights that closely replicate natural sunlight. The 20-watt bulbs were quite bright, and unlike the AeroGarden Bounty Elite, this is not a smart system, and the lights cannot be dimmed. Still, we found a spot where the lights weren't bothersome at night, eliminating the issue. The light's timer automatically turns them on and off according to the type of crop you've planted, with the start time being the time you turn the system on. We appreciated the reminders to add water and fertilizer, which took all of the guesswork out of growing the herbs. Fertilizer is added every two weeks, and we needed to add water around once per week.

Each included herb comes with an estimate of its sprouting time, and we found those to be quite accurate. The two varieties of basil sprouted in just a few days and grew quickly, but the other herbs weren't far behind. All of the plants were healthy and green, although we didn't trim them as often as we could have. We like the easy-to-read digital display and the attractive stainless steel finish, both of which give the system a sleek, modern appearance. All in all, this is a great way to keep healthy, fresh herbs right at hand to liven up your cooking.

Final Verdict

After extensive testing, we found that the AeroGarden Bounty Basic Indoor Garden takes a lot of the guesswork out of gardening, earning our best overall spot on this list. It comes with automatic lights and a touchscreen control panel which reminds you to add food and water as needed. Plus, it comes with nine different pods. If you’re looking for a more affordable, space-saving option, we love the Click & Grow The Smart Garden 3, our best for small spaces pick, which also performed very well in our tests. Simple and stylish, this system allows you to grow three plants at once and has a grow light and watering system to keep your plants healthy.

Other Options We Tested

The following products are two that we tested and found impressive. Though they fell a bit short of our standards, we think they're still worth considering.

Aerogarden Sprout With Gourmet Herbs

Enjoy Gardening Year-Round With These Indoor Garden Systems (27)

The Aerogarden Sprout is a much more compact system than many other Aerogarden products—it holds just three plant pods at a time—and it comes with basil, parsley, and dill. Like other Aerogarden systems, you can adjust the height of the grow lights, but only up to 10 inches maximum, which is rather low. And we found setting up the timer for the grow lights to be somewhat confusing. Still, if you want an Aerogarden for growing healthy herbs indoors, and you don't have a lot of room, this is still a good option to consider.

Gardyn 3.0 Hydroponics Growing System

Enjoy Gardening Year-Round With These Indoor Garden Systems (28)

While we like this admittedly pricey smart indoor growing system, and especially like the way its app helped guide us through all aspects of setup and maintenance, we ultimately felt that this system is just too large for most apartments. It's designed for growing crops vertically, and it measures a whopping 5 feet high, 2 feet wide, and 1 foot deep. Plus, the grow lights are very bright and the pump is somewhat loud. Still, if you want to grow a large crop of herbs and vegetables—the system holds up to 30 plants at a time—this is definitely worth a look.

How We Tested the Indoor Garden Systems

We tested 18 indoor garden systems at our own homes across the country for six weeks (18,144 hours and counting!). Each indoor garden was evaluated on setup, ease of use, design, performance, quality, and value.

  • Setup: We used a timer to note how long it took from the time the box was opened until the garden was set up and ready for the seeds to be planted. We then set up the grow lights for systems that include them (all of our final picks have grow lights) and positioned the system in a spot where the grow lights would be the exclusive source of light for the plants. For systems we tested without lights, we placed them near a window that receives plenty of sunlight. Next, we planted the seeds or seed pods in the garden system according to the manufacturer's instructions. For those systems that did not include seeds, we used basil seeds.
  • Ease of use: During the entire testing process, we evaluated how easy it was to maintain the garden system, how often water or nutrients needed to be added, and how quickly the plants sprouted and grew.
  • Design: We scored the indoor garden systems on how well any timers, pumps, apps, lights, and other features performed. We also considered the amount of space the garden systems required, and the variety of seeds that were included.
  • Performance: For the initial six-week testing period, the gardens were maintained according to the manufacturer's guidelines. We strove to keep the temperature at a steady level: no lower than 60 degrees and no higher than 80 degrees. We used a hygrometer to monitor the humidity level in the room where the garden was placed, aiming to keep the humidity between 40 percent and 60 percent. Whenever possible, the grow lights were kept on for 14 to 16 hours a day. The height of the seedlings was measured at 3 weeks and again at 6 weeks. If plants had matured enough for harvest during the testing session, they were used for cooking and evaluated for taste.
  • Quality: We considered the overall health of the plants, including any browning of leaves, stunted growth, or other issues.
  • Value: After the testing period, we noted what we liked and didn't like about each indoor garden system and if we felt that the price was reflective of its features.

What to Look for in Indoor Garden Systems

Grow Lights

Grow lights mimic natural sunlight and provide a full spectrum of light for optimal plant growth. Without grow lights, your plants must receive an adequate amount of sunlight from a nearby window to stay alive indoors. A small herb garden might get enough sun on a windowsill, but you’ll likely need LED grow lights for larger plants to thrive in your home. Most indoor garden systems, including all of our top picks, come with a built-in lighting system.

Seedlings in particular benefit from grow lights, because they tend to be healthier for transplanting. According toAaron Steil, Consumer Horticulture Extension Specialist, Department of Horticulture, Iowa State University, "They transplant better than lanky ones, and almost universally, we don't have enough light even in the brightest windows to produce robust stocky plants."

Typically, indoor hydroponic garden systems have a timer that controls the lights. A common pattern is 16 hours on/8 hours off—our best overall runner-up, the inbloom Hydroponics Growing System Starter Kit follows this pattern—but others follow a 12 hours on/12 hours off pattern. Most basic systems don’t allow you to change the timer’s settings, but simply begin the countdown starting from when you turn the system on. Most smart indoor gardens, including our best smart pick, the AeroGarden Bounty Elite, on the other hand, do allow you to adjust the grow light timer to suit your own preferences. Still, it’s important to provide your growing plants with no less than 12 hours of “sunlight” per day, and preferably more.

System Type

There are three basic types of indoor garden systems: hydroponic, aquaponic, and soil-based. All typically rely on grow lights to provide enough light for healthy plant growth. Hydroponic systems are the most common, and the easiest to maintain. All of our top picks are hydroponic. While we did test some soil-based and one aquaponic system, none scored high enough to be included in our roundup.

  • Hydroponic gardening at its most basic is the replacement of soil with nutrient-filled water to nourish the growing plants’ roots. You’ll need to be sure your system doesn’t run low on water, will need to add nutrients to the water periodically, and will need to clean out the entire system between crops, but beyond those tasks, these systems are quite easy to maintain and don’t make much mess.
  • Aquaponic systems have a unique component–a fish tank that mimics a natural ecosystem. Fish waste acts as a fertilizer and encourages plant growth. In turn, the fish feed on the decomposing plants, though supplemental fish food is required. These systems are basically a small fish tank with a lidded top that holds the plants, with the roots reaching down into the water. While an aquaponic system can successfully grow herbs or other small plants, you won’t be able to grow as large a garden as with other types of indoor gardens, and it can be challenging to keep the fish healthy and alive. Still, these systems can be a fun way to introduce children to the joys of gardening, or a unique way to keep a pet fish while growing a small herb garden.
  • Soil-based indoor gardens are the familiar potted plants grown in potting soil. On the plus side, these are easy to maintain and familiar to most people. Also, depending on the size of your containers and the height of your grow lights, you can potentially grow larger plants than would be possible in a hydroponic or aquaponic system. However, you’ll need to pay close attention to the soil moisture to keep your plants healthy, and there is more potential for soil gnats, spilled dirt, and mess with a soil-based system.

Size

Most indoor garden systems are designed to be set on a kitchen counter or similar perch. Generally, you’ll need at least a foot or two in width and depth to fit your garden system, but some are quite compact, making them a better choice for anyone who has little room to spare. For example, our best for small spaces pick, the Click & Grow Indoor Garden System, is only about 5 inches wide.

You’ll also want to consider the height of the system. Most allow you to extend the grow light arm higher as your plants grow. That means that if you’ll be setting the garden system on a counter underneath cabinets, you should first measure the space to be sure the grow lights will have enough room to fully extend. Also, the available growing space between the base of the system and the full extension of the lights to some extent determines what types of plants you can grow. Just about any indoor system has enough room for microgreens, lettuce, and herbs, but if you hope to grow tomatoes or other crops that need more headroom, you’ll want a system that can accommodate them. Our best overall pick, the AeroGarden Bounty Basic, has grow lights that can be raised to a maximum of 24 inches high, which is tall enough for just about any crop.

Ease of Use

Most indoor garden systems are fairly easy to maintain, but you still need to pay attention for the best results. Generally, with a hydroponics system, you’ll need to add water regularly to keep the reservoir from drying out. Typically, you’ll only need to add water occasionally at first, but might need to top off the tank every few days as your plants grow taller and thirstier. Some systems just have a small window that lets you see the level of the water, but others, particularly smart systems, will notify you via an alert on the app when the water is running low. For example, our best splurge pick, the Rise Gardens Personal Garden, takes all of the guesswork out of growing your own herbs and vegetables.

You’ll also periodically need to add more nutrients to the water in a hydroponic system. The nutrients are critical for healthy plant growth, as they mimic the nutrients that would be found in the soil. Expect to need to add water nutrients every other week or so. Smart systems will usually alert you when it’s time to add the fertilizer, but other systems usually require you to remember on your own. While not a fully “smart” system, our best for herbs pick, AeroGarden Harvest Elite, still provides prompts on its touch screen when it’s time to add water and nutrients. Most indoor systems come with the nutrients, but you’ll have to purchase more if you continue to use your garden long-term.

Of course, you’ll periodically need to empty out the water tank and clean the system thoroughly to prevent the growth of mold or algae. Generally, you will do this in between crops. Follow the manufacturer’s instructions for the cleaning procedure to avoid damaging the pump or other components.

Plant Type

Because an indoor garden system is typically sized to fit on a countertop, these are not intended for growing very large plants, such as zucchini, green beans, or gourds. However, they are ideal for smaller crops including lettuce, herbs, dwarf varieties of tomatoes, and many other small fruits, vegetables, and flowers. The ingarden Superfoods Indoor Growing Kit is somewhat unusual in that it’s designed only for growing healthy microgreens, not larger crops, however.

Typically, you’ll grow plants that are discarded after harvest in an indoor system, or use the system to start seeds for later planting outdoors. Perennial plants that live for several years are not the ideal choice for an indoor garden system, as periodically you’ll need to empty the system out for cleaning.

Because the grow lights of the garden system simulate natural sunlight, you don’t need to worry about the time of year, weather, or amount of sunlight available; you can grow your favorite herbs all year long.
