Benefits of Using a Garden Tower for Year-Round Gardening

Frost stops the outdoor harvest, and summer heat turns lettuce bitter. Even on a balcony, there’s only so much room for pots. Most home gardens stop when the weather says so.

A vertical garden tower doesn’t need outside conditions to thrive. It grows on water, light, and nutrients, all of which you can control, so the weather outside matters much less. But before you buy one, you should know what it does well and what it doesn’t.

Why a Vertical Garden Tower Keeps Going All Year

The ALTO Garden GX Tower has no soil. Plants sit in rockwool cubes or net pots, and water flows up and down the tower like a small fountain. Timers control the watering and the lighting.

So January looks like July, and you can set it once and let it keep its own time.

Move It Outside, Move It Back In

The GX Tower is portable and works both indoors and outdoors. Leave it outside when the weather is mild, and wheel it back inside when it’s too hot or too cold.

Going outside is more than convenient. Some cucumbers and tomatoes need pollination, which is much easier outdoors, where bees and a steady breeze do all the work. The sun also provides every wavelength your plants need, so the LED grow lights can stay in storage until the tower comes back indoors.

Will it survive the sun? Yes. The walls are 2 mm thick, so it won’t fade or discolor even after a whole summer outside.

Growing Indoors Without the Mess

A hydroponic tower garden doesn’t make a mess on the kitchen floor, which is a main reason it works so well as an indoor garden. The LED grow lights replace the sun, and the timers keep everything running.

The recommended settings are straightforward. Water for approximately 15 minutes each hour during a 14-hour period, and keep the lights on for 14 to 16 hours. That’s all that’s required. No gardening experience is necessary, and assembly takes about 20 minutes without any tools.

Space Is Where Towers Really Win

Each GX Tower supports 24 pots in 1 sq. mt of floor area. To do this on land, you would need 50 to 60 sq ft of space.

No backyard needed. For anyone in an apartment or condo, that gap settles the whole debate.

Faster Growth, Bigger Harvests

Plants grown with hydroponics and aeroponics can grow up to 3x faster than in soil, and the reason is simple. Nutrients are delivered directly to the roots, so the plants don’t waste energy searching for them in the soil and can spend it on growing and developing fruit. Roots also take in oxygen more efficiently, and watering is more exact.

You can also expect a 30% yield boost from the same system. Once you transfer your seedlings into the tower, you can expect your first harvest in around three weeks.

Water Use Drops Sharply

When you grow in soil, most of the water soaks into the ground before the plant can use it. A hydroponic tower garden recycles its water, saving 95% of the water you would use in a conventional garden. Grow year-round and you will see the difference.

What Grows Well (and What Doesn’t)

Leafy greens do well: lettuce, spinach, kale, chard, and bok choy. Herbs like basil, parsley, dill, thyme, rosemary, and chives all work well too. Fruiting plants such as tomatoes, cucumbers, peppers, and strawberries are also good for an aeroponic system.

Root vegetables are the exception. Carrots, potatoes, and onions grow underground and are difficult to harvest from the tower. If most of your crops are root vegetables, I’d recommend skipping the tower.

What to Compare Before You Buy

Not all towers are the same, so here’s what to check:

• Indoor and outdoor use. Year-round growing needs both, which the GX Tower offers.
• Lighting. The GX Tower arrives with an LED grow light for seedlings, and the GX light kit is equipped for growing inside. Many accessories, such as rockwool cubes and net pots, are already in the box.
• Timers. Check whether you get timers for both the water and the light.
• Materials. If the tower is going outside, check the quality of the materials, such as wall thickness and fade protection.
• Setup and support. A short setup time, a setup video, and someone to talk to are extremely helpful when you’re learning to set up a tower.

Getting Started

Sow your seeds in the rockwool cubes. When they sprout, place them under the LED grow light. When they’re around two inches tall, slide them into the net pots, set your timers, and stand back! You can see the first step in detail in our germination guide.

So, Is a Garden Tower Right for You?

If you want to grow greens and herbs all year round, have limited space, and want to use less water, a garden tower is probably a smart decision. If you grow a lot of root vegetables, then perhaps not.

For those who enjoy this style of growing, the ALTO Garden GX Hydroponic Tower with Grow Lights is suitable for indoor and outdoor use. Visit ALTO Garden to see the complete lineup.

Frequently Asked Questions

1. Can a vertical garden tower grow vegetables all year?
   Yes. Our towers grow plants on water, light, and nutrients rather than soil, so outside conditions have much less impact. Timers keep your tower watered and lit, creating a consistent environment year-round, regardless of the weather.
2. How much space does a hydroponic tower garden need?
   You can grow more in less space. For example, the GX Tower holds 24 pots in about 1 square meter of space, compared with the 50 to 60 square feet needed to grow the same number of plants in soil.
3. Which plants grow best in a garden tower?
   You can grow leafy greens like lettuce, spinach, and kale, and herbs like basil and parsley. Tomatoes, cucumbers, peppers, and strawberries also do well. Root vegetables like carrots, potatoes, and onions are hard to harvest, so skip them.
4. Does a hydroponic tower garden really save water?
   Yes. Hydroponic tower gardens recycle their water instead of letting it drain away into the ground. You’ll use roughly 95% less water compared to a conventional garden, and as you garden year-round, those savings increase.
5. Can I use a garden tower both indoors and outdoors?
   Yes. The GX Tower can stay outside in mild weather and be rolled back in when it gets too hot or too cold. Indoors, grow lights replace sunlight and timers automate the light cycle, so the tower keeps growing.
