FAQ

What is aeroponics?

Aeroponics—the technology Tower Garden uses—is the process of growing plants in an air or mist environment, without the use of soil. It is the most effective and efficient way to provide plants with the necessary nutrients, hydration and oxygen.

Is Tower Garden organic?

Because soil is a prerequisite for organic growing, and aeroponic systems don’t use soil, Tower Garden can’t be classified as organic. But it can be equally as safe and healthy—and more efficient.

Organic gardening requires organisms in the soil to convert “organic” material into minerals plants can use. But instead of growing plants in soil, Tower Garden uses water, oxygen and pure, natural minerals to deliver nutrients directly to plant roots.

The result is higher growth rates and greater yields than resource-intensive organic methods can achieve. And remember, since you’re growing the plants, you control the use of herbicides and pesticides.

So you could say Tower Garden is better than organic, because you get the same results (and more)—without the dirt.

What is Tower Garden made of?

Tower Garden is made from UV-stabilized, BPA-free, food-grade plastic. The high-quality plastic resins we use are compliant with both U.S. Food and Drug Administration guidelines for food contact and European guidelines for Restriction of Certain Hazardous Substances.

Our plastic is also completely opaque — it keeps out light, inhibiting algae growth. This keeps your plants happier and gives your Tower Garden a longer life. So you’ll enjoy growing your own food for years to come.

Tower Garden Mineral Blend contains a wide range of natural minerals.

What are Tower Garden's dimensions?

For Tower Garden HOME, the reservoir (at the base of Tower Garden) holds 13 gallons and is XX" x XX". It stands XX" tall and holds up to 32 plants.

For the Tower Garden FLEX, the reservoir holds 20 gallons and is 30" x 30". It stands 62" tall and holds up to 20 plants.  With an extension kit, Tower Garden is 81" tall and holds up to 28 plants.

Wondering how much space you need to grow a Tower Garden? A 3' x 3' square should do it.

Note: To maximize yield output, the Community Garden comes with extension kits.  So each of the 12 Towers is 81" tall and holds 28 plants (allowing you to grow a total of 336 plants).

How many plants can Tower Garden grow?

The number of plants your garden can grow depends on which Tower Garden growing system you use and which type of garden you grow.

  • Tower Garden Home holds up to 32 plants.
  • Tower Garden FLEX holds up to 20 plants — whether you’re growing vegetables, herbs, fruits or flowers. With an extension kit, you can as many as 28 plants.  With a baby greens extension kit, it holds up to 52 plants.
  • A Family Garden comes with 3 Tower Garden FLEX units. So you can grow up to 84 plants.
  • A Community Garden includes 12 Tower Garden FLEX units that are 7 sections tall. That means you’re able to grow as many as 336 crops at once!

Is Tower Garden good for schools?

Safe, compact and soilless, Tower Garden makes a great classroom growing system. Many schools already use Tower Gardens to engage students and bring lesson plans alive. While students witness first-hand how plants grow, they also learn the importance of sustainability, healthy eating and giving back to the community.

That’s why we’ve developed Tower Garden lesson plans and other teaching materials!

What can I grow with Tower Garden?

Vegetables, herbs, fruits, flowers—Tower Garden will grow just about anything except root crops, grapevines, bushes and trees.

Do I have to use Tower Garden Mineral Blend?

Designed specifically to support aeroponic technology, Tower Garden Mineral Blend plays a critical role in ensuring your Tower Garden grows healthy plants. We think you’ll find the Mineral Blend is most effective (and cost-effective) for achieving the best results.

How long does it take plants to grow in Tower Garden?

Tower Garden grows plants up to three times faster than conventional gardening methods. And many vegetables can be harvest-ready in as little as three weeks after transplanting.

Ultimately, time-to-harvest depends on a number of factors—such as climate, plant type, light exposure and more. But most seed packets offer a reliable estimate of how soon plants will be ready.
