How to Choose Your Hydroponic Growing System

You’ve seen those hydroponic growing systems for sale, and you’d like to buy one, but you’re not sure which one fits your needs. This article will help you choose an indoor garden.

Indoor gardens have come a long way since the days of plants in pots of soil crowded around a window, eking out a meager existence fighting over light from the winter sun. Advances in technology and new techniques have revolutionized indoor gardening in recent years.

An exciting example of technology and techniques merging into an awesome product is the hydroponic growing system. Hydroponic growing systems have flooded the market. Why? Because they work, they’re convenient, and they’re relatively inexpensive. (See related article, How a Self-Watering Hydroponic System Works.)

Of all the manufacturers selling hydroponic growing systems, AeroGarden is perhaps the most well known.

AeroGarden hydroponic growing system products are extremely popular and are generally the standard against which products from all other manufacturers are judged. Therefore, all the AeroGarden products are included in the matrix. Products from popular competitors will be included as well.

Let’s Clear Up Some Confusion

Choosing your first hydroponic growing system can be maddeningly confusing. They all look so much alike. Why choose this one over that one? What features matter most and which ones are of little value?

To assist you in making a decision, this article offers you a matrix of products and features. The article explains the meanings of the values in the chart.

Every attempt has been made to present accurate information, but products evolve and features change. Please confirm any information you read here before making your purchase to be sure you’re getting what you wish for.

Garden Environment

The table below describes the three core garden environment properties.
  • Number of plants it can grow
  • Power of the light
  • Highest the plant can grow before it bumps into the light
You’ll probably start your comparison shopping with these three properties.

You don’t need to know a bunch of technical information such as exactly how bright the light is per watt. Just pay attention to where a hydroponic growing system LED wattage lands in the range for comparison.

If you find a hydroponic growing system that supports a 24 inch plant like the Bounty but offers a 10 watt LED like the Sprout, you should question whether that unit can grow healthy plants. Why?

The greater the maximum plant height, the more powerful a LED grow light you want. The effect the light has on a plant decreases rapidly as the distance increases between them. You’ll see the correlation between LED wattage and maximum plant height in this chart.

To ensure the light is as close to the plant as possible, the hydroponic growing system you select should allow you to set the light very low against the growing tray and raise it until it reaches its maximum height as the plants grow taller.

The wattage of products in the chart ranges from 10 to 120 watts per garden. The (relatively) meager 10-watt LED in the AeroGarden Sprout hosts 3 plants under 10 inches tall. That’s suitable for small herbs and lettuce. Conversely, the two super-bright 60 watt LEDs on the 24XL support plants up to three feet tall, such as tomatoes, peppers, and squash.

The highlighted hydroponic growing systems stand out against the other units for the properties included on this chart.

Garden User Interface

You want to look for several factors in a user interface on your hydroponic growing system.
  • Ease of use
  • Helpful feedback
  • Control over growing conditions
You’re here to garden, not manage the settings on one or two (or twelve, because you’ll get hooked on growing food in these things!) hydroponic growing systems. The most basic units have little more than a power button. High-end units have touchscreen control panels plus Wi-Fi apps and can synchronize schedules with other units.

Buttons

Devices on the chart with only buttons operate entirely manually, except the iDOO 12-Pod, which has Wi-Fi. The interface is simple and intuitive. The device communicates garden status to you with lights that illuminate, blink, or change color. Some gardens may have an audible alarm.

Digital Display

The digital display enhances the garden device by offering you detailed feedback regarding the state of your garden. Rather than interpret a flashing light, you just read the text or view the icons on the digital display to learn what the garden is attempting to communicate to you.

Touchscreen

The ultimate in interaction with your hydroponic growing system is the touchscreen. The menu system guides you through set-up and offers lots of feedback. The screen is large enough to just explain to you what you need to know.

Wi-Fi

The devices with Wi-Fi communicate with an app you install on your iOS or Android phone. You can manage many settings from your phone using the app. You may be able to synchronize multiple hydroponic growing systems, if they are compatible. Wi-Fi connectivity is a tremendous convenience you don’t want to overlook.

Before you buy a garden with Wi-Fi connectivity, make sure it will work on your wireless router. Is the hydroponic growing system connecting via 2.4GHz or 5GHz? Make sure your wireless router supports that frequency. Most routers handle both frequencies, but things change.

Vacation Mode

Finally, the vacation mode gives you peace of mind knowing your garden is less likely to run dry while you are away on vacation. The device reduces the amount of light it shines on your plants each day, slowing their growth and also their water intake. Somebody was really thinking when they came up with this feature!

Garden Dimensions

Can you fit that hydroponic growing system on your countertop? Or, once you’ve gotten hooked on growing your own food indoors, how many growing systems can you fit?

As you consider the dimensions, picture your hydroponic growing system in various locations within your home. The kitchen counter is a convenient location for a garden, but plants look lovely anywhere you put them. Your hydroponic growing system can add a nice touch to the living room or dining room.

You’ll find below the dimensions of each hydroponic growing system. I highlighted no rows because each model is perfect for you if it fits where you want it.

Leave Extra Space

As you compare dimensions you’re probably thinking in terms of placing the garden along a wall. Will it fit between the mixer and the toaster? But remember that plants grow in all directions. Be sure you leave space between the garden and the wall for the plant to fill out.

You also need room to reach behind if you are picking tomatoes or peppers. Reaching through the plant or over the top of the light assembly may not be feasible.

Leave Extra Height

And on the topic of tomatoes and peppers, remember that the plant does not know to stop growing when it reaches the light. It may grow taller than the height of the garden unit. If you place your hydroponic growing system under a kitchen counter or shelf, plant height may become an issue.

Your plant is unharmed by growing beyond the light, although those branches are missing out on the benefits of the light. Just be sure enough of your plant gets that light to make up for the parts that do not. You may consider pruning the plant to keep all its leaves under the light.

Other Lighting

Another factor that may become an issue with a garden under the cabinets is any under-counter lighting system. Your garden simulates night and day with its timer and counter lights may interfere with that schedule. It may not be a big thing, but something to consider as you ponder where to place your indoor garden.

Stacking

The 24XL stands almost four feet tall and it’s taller than that if you set it on a stand to keep it off the floor. Moreover, the Farm series is stackable, so your garden could be six feet tall with a 24 Basic stacked atop a 24XL (or vise versa).

Garden Accessories

You can get more from your hydroponic growing system with some included or optional accessories. These gardens are very versatile!

The table below highlights availability of three garden accessories.

  • Seed starter tray (optional)
  • Microgreens tray (optional)
  • Trellis attachment (optional/included)

A seed starter tray holds more grow plugs than the regular tray. The seed starter tray has specialized built-in pods to hold the grow plugs. You start a seed in each grow plug and transplant the grow plug to soil once the seedling has grown enough. A seed starter tray is not intended to grow plants to maturity.

The microgreens tray provides a flat area for seeds to grow and be harvested as microgreens. The microgreens tray replaces the garden tray.

Finally, the taller AeroGarden gardens include mounts to support a trellis. When growing larger plants such as tomatoes or peppers a trellis helps keep things contained. For plants such as cucumbers, you can wind the vine around the trellis to maximize the plant’s access to the light.

The highlighted cells in the chart indicate that accessories are available. The trellis is included with your AeroGarden. The trays are available for separate purchase.

If you have no interest in transplanting seedlings or growing microgreens, the availability of these optional trays should have no effect on your choice of hydroponic growing system.

You don’t need the seed starter tray to start seeds. You can start seeds in the regular tray and just move them when the seedling is ready. The starter tray allows you to start more seeds in the same space and do so without using any drop-in pods. With the seed starting tray, you just drop a grow plug into the build-in pods.

Common and Manufacturer Exclusive Features

Your hydroponic growing system should allow for some form of grow plug and come with a low water indicator and a LED grow light on a timer. These features are what all systems have in common. Certain very low-end kits may lack these features, but arguably those kits cannot be considered a hydroponic growing “system”. Manufacturers include features that make their hydroponic growing systems stand out.
  • The 10-pod and 12-pod iDOO systems have a built-in fan to agitate the plants. This helps self-pollinating plants like tomatoes and peppers grow fruit and can stiffen up leaves on your greens.
  • The AeroGarden Bounty and Farm series gardens offer dimmable lights and a sunrise/sunset light setting.
  • The iDOO models include a feature allowing you to switch your grow light between vegetable and fruit modes.
  • Some countertop models allow you to detach the lighting assembly. You can be a little more DIY with how you set up your device.
  • The AeroGarden Farm series is stackable.
One distinguishing feature not compared above is tub capacity. How much water does the hydroponic garden hold in its reservoir? The more water it holds, the longer you can be away from home without worrying about your plants running out. Compare your prospective gardening system units based upon how many liters of water each holds.

Buying Your Hydroponic Growing System

Hydroponic growing systems are an exciting and ever-evolving tool for growing food indoors. Prices are coming down even as manufacturers add features.

Accessories

Accessories can strengthen your investment in your garden. What accessories are available for the hydroponic growing system you’re considering? For example, a seed starter tray could save you some money if you have outdoor raised beds. Rather than buying seedlings from the nursery for $5 to $10 each, you can buy a $3 package of seeds and grow the seedlings yourself.  Even factoring in the cost of the grow plugs, it’s a deal. The seed starting trays also work well to provide you with seedlings for a full-blown hydroponic system, which lacks the ability to start seeds.

Wi-Fi Connectivity

Watch for connected gardens to become more popular. With a single application on your phone you can manage multiple gardens. You can synchronize the light and feeding schedules. You can track your plant’s progress. Don’t discount how convenient you’ll find this feature as you keep buying more and more gardens. Because you can’t stop at just one!

DC Power Ratings

If you are living off-grid or in an RV, you may want to wire your hydroponic growing system directly to a DC source. Check the voltage of the hydroponic growing system before purchase. Some devices run 12V but others run 24V or something else entirely.  

Ease of Maintenance

Your hydroponic growing system needs your attention for cleaning and keeping the water fresh. When comparing devices, look for features that make maintenance easier and quicker.

  • On devices with a larger water reservoir, does it include a drain plug?
  • How do you drain the water on larger systems that sit on the floor?
  • For countertop devices, does the tub detach from the base?
  • What parts are dishwasher-safe?

Each manufacturer approaches maintenance differently. Some make it easier than others. You may need to dig into product reviews to see how people rate the ease of maintenance of each product.

Key Takeaways

Hydroponic growing systems work. They’re spectacular. And the market offers you so much variety in indoor garden systems. You can have a tiny garden with just a few herbs or a huge garden with multiple plants three feet tall. Manufacturers distinguish their products with innovative new features and conveniences.

This article provided you with a comparison based upon the number of plants a system can grow, the dimensions of the system, the interface you’ll use with the system, and accessories available for the system. You can use the charts to compare hydroponic growing systems from other manufacturers to be sure you’ll get the features you need to make your garden a success.

Once you see how fun and easy growing food indoors can be with your first hydroponic growing system, you’ll be right back here comparing models for the purchase of your second, and third, garden system.

Please check back with this article from time to time. It will evolve as the market grows.
