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.

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.

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. You can view Mineral Blend ingredients here.

For Tower Garden HOME, the reservoir (at the base of Tower Garden) holds 13 gallons and is 24" x 24". It stands 58" 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).

We currently sell and ship Tower Garden within the U.S. and Canada only. You may purchase Tower Garden directly from our website or from a sales representative in your area.

The number of plants your garden can grow depends on which Tower Garden growing system you use an 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!

Thanks to its compact, vertical design, Tower Garden HOME and Tower Garden FLEX fit almost anywhere.  But there are a few things to consider when picking a place for yours:

Light

• For fruiting crops—such as tomatoes, cucumbers, squash—to be most productive you’ll need full sun (about eight hours daily).
• Greens, herbs and other vegetable crops tolerate lower light levels. But they’ll be less productive as the amount of light decreases.
• Many flowers and ornamental plants grow fine in shade. Read seed labels to determine required light levels.
• Growing indoors? LED indoor grow lights help to provide consistent light for your crops.
• If you are growing outdoors and live in a region with intese summer heat, your plants may appreciate light shade in the mid-afternoon.
  

Water

Since Tower Garden uses water and nutrients rather than dirt to grow plants, access to good, clean water is critical. To avoid damaging your plants, never use heavily chlorinated water, very hard water or softened water.

• To remove chlorine, fill a bucket with water and leave it in the sun for 48 hours.
• To offset hard water, fill your Tower Garden using an RV water filter (available online and at many stores).
• To remedy softened water, you’ll need a reverse osmosis system. You can purchase a small sink unit for under $200.
• Alternatively, you can buy bottled water (ideally the 3- or 5-gallon size) to fill your Tower Garden.
  

Electricity

To power the pump (and grow lights if you’re growing indoors) you’ll need an electrical outlet. For safety, always use a waterproof connection when using outdoor extension cords.

Temperature

From Florida to Alaska, Tower Gardeners grow food in a variety of places and under an array of conditions. We recommend keeping the internal temperature of your Tower Garden between 65–85?F.

If you're growing outdoors there are simple ways to achieve this (e.g., adding frozen water bottles to the reservoir in hot weather, heating your Tower Garden with a water heater in cold weather). Should your conditions become too extreme, growing indoors is always an option as well.

Other Considerations

Tower Garden must be level to work properly (otherwise, plants won’t be watered consistently and the system may leak). So select a spot that’s already level or that can be leveled.

Absolutely! Tower Garden Home includes LED indoor grow lights to make sure your crops get the amount of light they  need.  For the Tower Garden FLEX Growing System, the Tower Garden Grow Lights Kit allows yout o grow leafy greens, herbs and other non-fruiting plants indoors year-round, regardless of climate and season.

For best results, set the pump timer for 15 minutes on, 45 minutes off, and the light timer to 14 hours on. And to reduce risk of pests and plant disease, provide adequate air circulation in your growing area, and start with new plants rather than outdoor transplants.

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! Learn more about our school resources »

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

Yes, you may use any type of seed you like. And if you don’t want to start your own seeds, you can also buy seedlings and simply transplant them to your Tower Garden.

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.

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.

Most people are able to assemble Tower Garden in 20–25 minutes. Step-by-step instructions are included with each Tower Garden HOME or Tower Garden FLEX Growing System, and no previous gardening experience is required.
