“Where’s the soil?”
That’s one of the most common questions people ask me when they see my Tower Garden, whether in person or online.
The answer is, there’s no soil.
That’s because the Tower Garden is a form of aeroponics.
Let me begin by describing hydroponics because most people are more familiar with it.
In hydroponics, plants grow in water, with no — or very little — soil.
Their roots are submerged in water the whole time.
Aeroponics is similar to hydroponics, but in aeroponics, the plants’ roots aren’t in the water the entire time. Instead, the plants’ roots are suspended in air.
Hence the name, “aero”-ponics.
Every few minutes, the plants receive a misting or sprinkling of water. This is accomplished with the use of a pump that pushes the water to the top of the tower. From there, it flows down to the roots of each plant, as this video demonstrates.
Since the roots are in air most of the time, they get a lot of oxygen. This results in healthier plants that grow faster than plants grown in soil.
This also means the Tower Garden eliminates the need for digging, weeding, and mulching.
Tower Garden Mineral Blend
Because there’s no soil in both hydroponics and aeroponics, plants need to get their nutrients from somewhere else.
That’s where Tower Garden Mineral Blend comes in. Containing all the nutrients plants need to grow, Tower Tonics A and B are added to the water.
In hydroponics, you’d need to use different plant nutrients, depending on the plants you’re growing and the stage of growth they’re in. For example, there are nutrients specifically for the seedling phase, for stimulating the growth of foliage, and for fruiting.
On the other hand, Tower Garden Tonics are effective for everything you’ll ever grow in the Tower Garden and for all phases of growth.
But that’s not the only thing that makes Tower Garden Mineral Blend special.
While other hydroponics solutions contain nutrients essential for the growth of plants, Tower Tonics go beyond. They also contain trace minerals such as calcium, iron, boron, and zinc that humans need for health. (See ingredients below)
Mineral Blend A
- Total Nitrogen (N) – 2.0%
- Calcium (Ca) – 1.0%
- Chelated Iron (Fe) – 0.05%
Derived from: Calcium Nitrate, Iron Sodium EDTA
Mineral Blend B
- Available Phosphate (P2O5) – 1.0%
- Soluble Potash (K2O) – 3.0%
- Magnesium (Mg) – 0.5%
- Sulfur (S) – 3.0%
- Boron (B) – 0.01%
- Copper (Cu) – 0.001%
- Manganese (Mn) – 0.01%
- Molybdenum (Mo) – 0.0005%
- Zinc (Zn) – 0.005%
Derived from: Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Boric Acid, Copper Sulfate, Manganese Sulfate, Sodium Molybdate, Zinc Sulfate, Phosphoric Acid
This blend makes your plants not only healthier but also more nutritious!
Take a look at some of the plants I had in my Tower Garden. These pictures show a side-by-side comparison of the same plants taken four weeks apart:
The Pros and Cons of Aeroponics
As you may have realized, aeroponics has many advantages:
- You don’t have to touch dirt or pull weeds.
- Plants are healthier due to receiving more oxygen.
- Water cycles throughout the closed system, so it uses less water than traditional gardening.
- The Tower Garden Mineral Blend helps plants grow better and produces more nutritious food.
But I would be remiss if I didn’t mention the disadvantages of aeroponics.
- It requires electricity (or some other source of power, such as solar) to run the pump.
- You rely on plant tonics to deliver nutrients to your plants.
Did I miss any?
The Bottom Line:
As someone who also grows organically in the ground in my backyard, I know first-hand how much easier and faster it is to grow great food using the Tower Garden aeroponics system.
That’s why I think the benefits of aeroponic gardening far outweigh the disadvantages.
Do you agree?
