Why Do Your Plants Need Artificial Light?
Have you ever brought a gorgeous new plant home from the nursery with lots of dense, sturdy foliage, only to realize a few months later that it’s become thin, pale, and straggly? Those are signals that your photosynthesizing friend is struggling to get the light it needs.
Most plants need at least 3 to 4 hours of natural sunlight a day, and many (especially vegetables) require as much as 12+.1 In indoor environments, plants may not get enough light exposure, so it’s important to understand how much light your plant needs and whether your current conditions allow for that.
The tell-tale signs of insufficient light exposure include:2
- Thin, weak stems that lean toward the light source
- Leggy growth (too much stem and too few leaves)
- Leaves that fade from dark green to pale green, yellow, or even white
How Does the Light Spectrum Affect Your Plants?
When you’re shopping for grow lights, you’ll find bulbs that put out full spectrum white, blue, and red light wavelengths. So what do your plants really need in a grow light? Let’s break it down:
- Full-spectrum – Different parts of the visible light spectrum appear to our eyes as different colors. Sunlight naturally contains all colors—in other words, it’s full-spectrum. All plants require at least some full-spectrum light to thrive. That said, plants particularly like blue and red light. As such, many grow lights are customized to emit more blue and red hues.
- Red light – Grow lights with more red lightwaves can help to promote flowering. This part of the spectrum can also help plants stay more compact.5
- Blue light – Blue hues can support healthy foliage. Grow lights with more blue output are good for sprouting seedlings and growing lettuce indoors, as well as foliage plants, and other leafy greens.6
- White light – White light, whether it’s LED, incandescent, or fluorescent, is not necessarily full-spectrum. Full-spectrum LED lights appear white because they contain all colors (just like sunlight).
