A floor standing grow light is the right choice for a large floor plant in a dim corner, because it is a lamp on a pole that shines down and needs no shelf, clamp or ceiling fixture. In the listings we read, the poles ranged from 15 in to 68 in, the timers offered 4 to 18 hours, and the footprints were small, from a 6 in base to about 7.9 in square. Choose by the height range first, then the timer, then the base, because a tall pole on a light base is the most likely to tip.

When a floor light beats a shelf light

A shelf light, such as an LED bar under a shelf, covers a tray of small plants. A floor light is for one tall plant or a group of pots on the floor, where there is no shelf to fix a light to. It can also be moved from one corner to another, which is useful in a rental or a small room where the light changes through the year.

The trade-off is floor space and looks. A pole and a base take a few inches of floor, and a lamp is visible. In a small room, a slim pole with a small base is the least intrusive.

Three floor lights compared

Aumtrly 68 in floor grow light

The listing is 7.87 x 7.87 x 68.9 in, weighs 1 kg and has 80 light sources. The text says the stand adjusts from 17 in to 61 in, with a 7.8 in flexible gooseneck at the top. It has three light modes, five dimming levels and a timer that goes up to 16 hours. The light includes red at 660 nm, warm light at 3200 K and white light at 5000 K, according to the seller. The shade is aluminum and the colour is white, which blends with a light wall. The size field says 68.9 in but the stand range says up to 61 in plus the gooseneck, so measure the lamp height you need.

GHodec free-standing gooseneck lamp

This listing is 47 x 6 x 6 in, weighs 2.9 lb and uses 80 LEDs in a 4-head bracket. The seller says the tripod stand extends from 15 in to 48 in, with a 5500K daylight spectrum made of 16 white and 4 red LEDs per strip. The timer offers 4, 8 and 12 hour options, there are five brightness levels, and it runs on a USB connector with an adapter included. The bracket is steel and aluminum and the seller says it dissipates heat quickly. It is the shortest of the three, so it suits a medium plant and a seedling tray on the floor, but not a tall tree.

68 in full spectrum floor light, 168 LEDs

The listing is 68 x 6.3 x 6.3 in and has 168 light sources. The telescopic pole adjusts from 16.5 in to 68 in. The timer has 6, 12 and 18 hour cycles with a memory function, and brightness runs from 20 percent to 100 percent in five levels, with warm white, cool white and full-spectrum modes. The seller says the base is weighted for tip-over protection. No weight is given in the fields we read, so check the listing for the base weight.

What to check before you buy

Height range

A floor light must clear the top of the plant and still be able to shine down at a safe distance. If your plant is 4 ft tall, a pole that goes to 68 in leaves room for the arm and the plant to grow. A 48 in pole is only suitable for plants under about 3 ft.

Timer

Plants need a regular dark period as well as light. A timer that restarts each day saves you from switching the lamp on and off. A 12 hour or 16 hour setting suits most houseplants, but check the plant you grow. The listings offered between 4 and 18 hours.

Base and stability

A tall, thin pole needs a heavy base. A weighted base, as in the third listing, and a wide tripod, as in the GHodec, are both better than a thin plate. Keep the lamp away from walkways and pets that jump.

Spectrum and brightness

Three modes and dimming let you change the light as the plant grows. Full-spectrum white is the safe default, and red light is added by some lamps to encourage flowering. Dimming lets you soften the light in the evening so the lamp does not glare in a living room.

Worked example: a 5 ft fiddle-leaf fig in a dark corner

Say a tall plant stands 5 ft (60 in) tall in a corner with no window, and you want a floor light that arches over it.

• Height. The light should sit above the top of the plant, so choose a lamp that reaches at least 68 in. A 48 in pole would be below the top leaves.
• Distance. Leave at least 12 in between the lamp head and the leaves, so the light does not scorch them. With a 68 in lamp and a 60 in plant, that leaves 8 in, so lower the plant by raising the lamp or choose a lamp with a gooseneck arm and tilt it down.
• Timer. Use a 12 hour cycle to start. In a corner with no window, 12 hours of light and 12 hours of dark is a standard routine.
• Footprint. A 7.87 in square base takes about 62 sq in, which is less than half a square foot.

The result: a 68 in pole with a gooseneck suits a 5 ft plant, but 8 in of clearance is tight, so choose the gooseneck version or a plant a little shorter. A 48 in lamp is only for plants under about 3 ft.

Placing the lamp

Put the lamp where light falls across the plant evenly. If one side of the plant faces the room, set the lamp on that side and turn the plant every week so it does not lean. Keep the cable tidy and away from water. In a living room, the lamp is more pleasant to live with if it is on a timer that turns off before bedtime.

Avoid putting a floor lamp in a doorway or between a sofa and a table, where it can be knocked. The corner behind the plant is better, with the pole at the back.

Setting the schedule through the year

Houseplants do not need a different schedule every month, but a light in a dark room does most of the work in winter, when natural light is weakest. In summer, if the corner gets some daylight, you can shorten the cycle or move the lamp closer to the window. Watch the plant: pale, stretched growth means it wants more light, and bleached or crisp leaves mean the lamp is too close or on too long.

Write the date you set the timer on a sticky note near the plug, so you remember when to review it after a month.

Heat, safety and energy

LED grow lights run cooler than older bulbs, but the head can still get warm. Keep it away from leaves and curtains. Do not cover the lamp, and plug it into a surge protector. If you have children or pets, choose a weighted base and tuck the cable away.

Who should buy a floor standing grow light

• Owners of a tall plant in a dim room.
• Renters who cannot fit a ceiling fixture.
• People who move plants between rooms.

Who should skip it

• Anyone short on floor space. A shelf light or a clip-on lamp uses none.
• Growers of many small plants. A shelf unit with built-in lights is more efficient.

Common mistakes to avoid

• Choosing by the size field alone. The stated height range may be shorter than the listed height.
• Ignoring the base. A tall pole on a light base tips.
• Leaving the lamp on all day. Plants need dark time.
• Putting the head too close. Leave a gap to avoid scorching.

Frequently asked questions

What is a floor standing grow light?

It is a grow lamp on a pole that stands on the floor and shines down on a plant, with no shelf or clamp needed.

How tall should a floor grow light be?

For a plant of 4 ft to 5 ft, look for a pole that reaches at least 68 in. For a plant under 3 ft, 48 in can be enough.

How many hours should a grow light be on?

It depends on the plant. The listings we read had timers from 4 hours to 18 hours. Many houseplants do well with about 12 hours.

Do floor grow lights tip over?

They can if the base is light and the pole is tall. Look for a weighted base or a wide tripod.

Is a floor grow light better than a clip-on light?

For a tall floor plant, yes, because it can be placed anywhere. For a shelf, a clip-on or a bar light is smaller.
