Aerogarden Harvest vs Harvest XL: Which To Choose?

Hey everyone! Today, I’m going to compare two closely related hydroponic systems from Aerogarden: the Harvest and the Harvest XL. The most noticeable difference is that the Harvest XL is bigger than the standard Harvest.

Additionally, the Harvest XL comes with more powerful LED lights. Stay tuned as I dive into these and other differences in more detail.

The Harvest XL is about 6 inches taller, almost 2 inches wider, and a bit deeper than the standard Harvest model. This means you’ll need more space for the Harvest XL, but it also lets you grow larger plants.

Although both units feature 6 planting holes on their growing decks, the Harvest XL has a deck area of 76.2 square inches compared to the Harvest’s 58.2 square inches. This results in more space between the holes on the Harvest XL, giving plants more room to spread out and grow.

One clear advantage of the Harvest XL is its higher grow height, which is 18 inches compared to the Harvest’s 11 inches. This allows you to grow taller plants like cucumbers, tomatoes, and dill.

Another perk of the Harvest XL is its 4-liter water bowl, whereas the Harvest comes with a 2.5-liter bowl. The larger bowl means you don’t have to refill the water as often and provides more space for root growth.

Overall, the Harvest XL offers greater flexibility in what you can grow, making it the more versatile option when compared to the standard Harvest.

The Harvest XL comes with 25-watt LED lights, compared to the Harvest’s 20-watt LEDs. While a 5-watt difference might seem minor, I’ve found that it actually makes a noticeable difference in how quickly plants grow.

Additionally, the light hood area on the Harvest XL is nearly 50% larger than that of the Harvest. This means that a larger area gets illuminated, giving plants more room to flourish.

So when it comes to lighting, the Harvest XL definitely has the edge over the standard Harvest.

Trellis system

The Harvest XL comes with a built-in trellis system, which is a major plus. This feature keeps plants upright as they grow tall, so you don’t have to fret about finding something to tie them to.

On the flip side, the standard Harvest model lacks this convenient system, and there’s no easy way to add one. The best I’ve managed is tying a plant stem to a light post.

Having a trellis system in indoor hydroponics is incredibly handy. The absence of this feature in the regular Harvest model is a significant drawback.


Both the Harvest and Harvest XL models are on the pricier side compared to their competitors. The standard Harvest is priced at $100, which may seem steep when you can find similar hydroponic systems for $60-$80. However, given Aerogarden’s quality and its unique water distribution system, the cost seems justified.

The Harvest XL carries a price tag of $139, which is also on the higher end. You can find cheaper alternatives, like the Spider Farmer SF-Smart G12, currently priced at $80. It comes with a 6-liter bowl and 36-watt LEDs.

So, is it worth shelling out the extra cash for the Harvest XL? In my opinion, it is. If you’re just looking for a small hydroponic setup, the regular Harvest should suffice. But if you’re in the market for a larger system, the additional $40 for the Harvest XL doesn’t seem like too much to ask.

Other features

Here, I’d like to discuss the features that both devices share.

Both have an identical control panel, featuring three buttons. These buttons let you switch the light on and off, schedule when the light should turn on automatically, and set reminders for plant food.

Each device comes with six reusable growing baskets that include sponges. These sponges are single-use and can either be pre-seeded or empty, depending on what you prefer. Additionally, both kits include a 3 oz bottle of plant food and transparent grow domes.

Another common feature is the water pump, located at the bottom of the bowl. This pump circulates water to the growing deck. Both units operate at a noise level below 35 dBA and come with a filter for the pump.

Regarding maintenance, both systems should be cleaned at least once a month and require a water change every two weeks. The process is straightforward: simply remove the bowl and disconnect the pump wire from the base. After that, you can move the unit to the sink for cleaning.


In summary, both devices offer excellent quality and efficiency, but they’re designed for different purposes. Understanding your specific needs and goals for a hydroponic system is key to making the right choice.

The standard Harvest model is ideal for beginners—those who are new to the world of hydroponics. This device offers a great learning experience, helping you understand the basics and potential challenges of hydroponics. It’s perfect for growing herbs or leafy greens.

On the other hand, the Harvest XL takes hydroponics to the next level. It’s designed for those who are looking to grow larger plants and achieve better yields. With this system, you can easily produce enough lettuce or herbs to sustain yourself and another person. It’s even capable of supporting a cherry tomato bush that will yield a respectable amount of fruit.

That wraps up my comparison of these two fantastic devices. Good luck, and all the best in your hydroponic adventures!
