Why Do Indoor Plant Lamps Often Look Pink or Purple?

What Crafty Clover says in this video

Intro

Hi there, curious minds! I'm Crafty Clover! Let's discover something amazing. Why do indoor plant lamps often look pink or purple?

The Big Idea

Indoor plant lamps often look pink or purple because they use red and blue light! Plants use those colors the most. Mixing red and blue makes the glow look pink or purple.

Leaf Colors

Step one: leaf colors. Plants use red and blue light the most, to make their food. They reflect green light, which is why leaves look green.

Red and Blue

Step two: grow lamps. Grow lamps often use only red and blue LEDs to save energy. They skip colors that plants use less, so less energy is wasted.

Pink Glow

Step three: pink glow. Mixing red and blue light makes the glow look pink or purple. Plants grow well under it, but the room looks strangely colored, and a white light helps people see.

A Closer Look

Let's take a closer look! Red light helps plants grow. Blue light helps too. Together they glow pink or purple. And the plant grows well.

Quick Facts

Quick facts! Greenhouses use grow lamps to keep vegetables growing through dark winters. Plants make food from light in a process called photosynthesis. Some grow lamps also add white light, so they look less pink and are easier on our eyes. Plants also need water, air, and a little warmth.

Think Like a Scientist

Now, think like a scientist! Plant cress seeds in two cups of damp soil. Put one on a sunny windowsill and one in a dark cupboard. Check them each day for 5 days, and write down what you see. How do the plants differ?
