FAQ's
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.
Growing your own clean, healthy food is certainly rewarding, but Tower Garden also offers a plethora of additional benefits you can feel good about, like reducing food miles, contributing to sustainability efforts, being an educational resource and reducing grocery bills. Check out all of the wonderful benefits Tower Garden has to offer.
For Tower Garden HOME, the reservoir (at the base of Tower Garden) holds 13 gallons of water and is 24" x 24" (2 sq. ft.). It stands 58" tall and holds up to 32 plants (16 full-size plants + 16 baby greens/herbs).
For the Tower Garden FLEX, the reservoir holds 20 gallons of water and is 30" x 30" (3 sq. ft.). It stands 55" tall and holds up to 20 plants. Extension kits are available for the FLEX unit providing growing ports.

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.
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.
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!
Vegetables, herbs, fruits, flowers—Tower Garden will grow just about anything except root crops, grapevines, bushes and trees.
Thanks to its compact, vertical design, Tower Garden fits almost anywhere, indoors or outdoors. 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 intense 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 timer and LED Indoor 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
- 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 and the Tower Garden FLEX are capable of indoor growing when paired with the LED indoor grow lights. The lights are full spectrum and support leafy greens, herbs, fruiting and flowering crops indoors year-round, regardless of climate and season. Just stay on top of your pruning and hand-pollinating…unless you have a house full of bees.
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.
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.
