Okay, so I’ve been messing around with growing some herbs indoors, and it got me thinking – do these plants actually need UV light, or is regular light enough? I decided to do a little experiment to find out.
Setting Up the Experiment
First, I grabbed a few basil plants – all roughly the same size and health. I wanted everything to be as consistent as possible so I could really see the difference the light made.

I set up three different growing areas:
- Area 1: Got a regular LED grow light. Nothing fancy, just your basic white light.
- Area 2: This one got a grow light that specifically said it emitted UV light. I figured this would be my “test” group.
- Area 3: My control group. These plants just sat by a sunny windowsill.
I made sure each area got the same amount of light each day – about 12 hours. I also watered them all the same amount, and used the same type of soil.
Watching and Waiting (and Taking Notes!)
For the next few weeks, I kept a close eye on my basil babies. I jotted down notes about how they looked, how fast they were growing, and any other changes I noticed.
Here’s what I observed:
- Regular LED Light (Area 1): These plants did okay. They grew, but they were a bit leggy, reaching for the light. The leaves were a decent green, but not super vibrant.
- UV Light (Area 2): These guys were interesting. They seemed a bit more compact than the ones under the regular LED, and the leaves were a deeper green. They looked…sturdier, somehow.
- Window Light (Area 3): These plants were pretty happy campers. They grew well, had good color, and seemed generally healthy.
My (Totally Unscientific) Conclusion
So, based on my little experiment, it seems like plants can grow with just regular light, but they might not be at their absolute best. The plants under the UV light seemed to do better than the ones under just the regular LED. I am very exciting when I saw different result on them.
It makes sense, really. Plants evolved to grow under the sun, which includes UV light. It’s probably not essential for basic survival, but it seems to play a role in things like leaf color and overall plant structure.
I’m definitely going to keep experimenting with this! Maybe I’ll try different types of plants, or different levels of UV light. It’s pretty cool to see how these little things respond to different conditions.
