Okay, so I wanted to share my little journey with using UV lights for my indoor plants. It wasn’t super scientific, just me trying things out because my plants looked a bit sad, especially when the days got shorter.
Figuring Things Out
First off, my apartment doesn’t get a ton of direct sunlight. Some of my green buddies were looking stretchy and pale. I’d read online somewhere, maybe a forum or something, about plants needing UV light, like they get outside. Sounded logical, right? So, I thought, “Okay, let’s get some UV light on them.”

I started looking around online. Man, there are tons of options. Some looked really complicated, like professional setups. I just wanted something simple. I wasn’t trying to start a commercial greenhouse in my living room. I ended up finding these clip-on lamps with adjustable arms. They weren’t too expensive, which was good because I wasn’t sure if this UV light thing would even work.
Getting Started and Setting Up
The light arrived pretty quick. Pulled it out of the box. It had a couple of light bars on bendy arms and a clip. Seemed easy enough. I clipped it onto a bookshelf near a cluster of plants that seemed most desperate for help. The tricky part was figuring out how close to put the lights. I didn’t want to fry them. I started with them about a foot away, pointing down.
Then came the timing. How long do you leave this thing on? The instructions were kinda vague. I decided to start with about 6 hours a day. I bought a cheap outlet timer – you know, the kind with the little pins you push in – so I wouldn’t have to remember to turn it on and off every single day. Plugged the light into the timer, set it for the morning hours, and hoped for the best.
Watching and Waiting
For the first week or so, I didn’t see much difference. I was checking the leaves every day, poking the soil, probably annoying the plants more than helping them. I was worried I might be doing more harm than good. Was the light too close? Too far? Not the right kind of UV, maybe?
But then, maybe around week two or three, I started noticing things.
- My little succulent that was getting tall and skinny started to look a bit more compact.
- A couple of my leafy plants seemed perkier, their leaves a bit greener.
- One plant near the edge didn’t seem to care much, so I adjusted the light arm to point more towards it.
I eventually bumped the timer up to about 8-10 hours a day, especially during the really gloomy winter months. I also played around with the distance. If leaves looked like they were getting scorched or too pale, I moved the light back. If plants were still stretching, I moved it a tiny bit closer.
So, What’s the Verdict?
It definitely helped. My plants aren’t winning any awards, but they look much healthier than before. They survived the winter without getting all leggy and sad. New growth seems stronger. It wasn’t like flipping a switch and having a jungle overnight, but it made a noticeable difference for my situation with low natural light.

Was it specifically the “UV” part? Honestly, I’m not sure anymore. Reading more later, people talk about “full spectrum” and PAR values and stuff. Maybe the light I got wasn’t strictly UV, or maybe that wasn’t the most important part. But whatever that clip-on lamp was putting out, my plants seemed to appreciate it.
So yeah, that was my experiment. Started with a problem, grabbed a simple tool, fiddled with it until things got better. It’s an ongoing process, really. Still adjusting things now and then. But for keeping my indoor green friends happy when the sun won’t cooperate, these lights were a pretty good find.
