The Science Behind Tower Gardens: A University of Mississippi Study

Ever wondered if growing your own food in a Tower Garden is really worth it? Well, the researchers at the University of Mississippi did too—and they put it to the test! Their study compared the nutritional content and yield of leafy greens grown in a Tower Garden (aeroponic system) versus traditional soil farming. The results? Pretty incredible!

More Greens, Less Space

One of the biggest findings was that Tower Gardens produced significantly more food per square foot than traditional soil-based farming. In fact, the study showed that aeroponic growing systems yielded 30% more fresh produce while using 90% less water. That means more leafy greens for your salads, smoothies, and sandwiches—all without the backbreaking work of traditional gardening. 

Here’s how much more food aeroponic plants produced compared to their soil-grown counterparts:

• Basil – 19% more

• Chard – 8% more

• Red Kale – 65% more

• Parsley – 21% more

• Bell Peppers – 53% more

• Cherry Tomatoes – 35% more

• Cucumbers – 7% more

• Squash – 50% more

Nutritional Powerhouse

What about the health factor? The study analyzed phenolic content, flavonoids, and antioxidants—the good stuff that helps keep our bodies healthy. The results showed that aeroponically grown crops had comparable levels of these beneficial compounds to soil-grown crops.

Some minor differences were noted:

• Phenolic content was slightly higher in soil-grown basil, chard, and parsley, but red kale had more when grown aeroponically.

• Flavonoid content varied, with parsley leading the pack in soil, but red kale showing higher levels in aeroponics.

• Antioxidant activity, measured by DPPH and cellular antioxidant assays, was very similar between the two methods, meaning aeroponic crops deliver the same health benefits!

Simply put, the food grown in a Tower Garden isn’t just abundant—it’s packed with the good stuff your body craves.

Faster, Fresher, Better

Another major takeaway? Tower Gardens don’t just produce more and better food—they do it faster. The study found that leafy greens reached maturity up to three times quicker than their soil-grown counterparts. That means you get to harvest and enjoy homegrown produce in record time. Plus, because Tower Gardens are vertical and self-contained, you can grow year-round without worrying about soil quality, soil-borne diseases and pests, or unpredictable weather.

Why This Matters for You

This study makes one thing clear: aeroponic gardening can produce just as nutritious food as traditional farming—but with significantly higher yields. Whether you’re an urban gardener, a homesteader, or just someone looking for a more efficient way to grow fresh food, aeroponics proves to be a game-changer, it’s no wonder Tower Garden owners rave about their results.

So, if you’ve been on the fence about starting your own Tower Garden, let science be your guide—because the proof is in the produce! You can read the full study here.
