How much faster do plants grow with a grow light?

Grow lights are designed to simulate sunlight, providing the energy that plants need to photosynthesize and grow. But how much do they actually affect plant growth? Generally speaking, plants grown under grow lights will grow slightly faster than plants grown in natural sunlight.

The amount of speed increase will depend on the type of grow light used, as well as the plant species. For example, a study published in the journal HortTechnology found that lettuce grown under high-pressure sodium (HPS) grow lights grew about 25% faster than lettuce grown under natural sunlight. In another study, researchers found that tomato plants grown under LED grow lights produced about 30% more fruit than plants grown under natural light.

Of course, there are many other factors that affect plant growth, such as watering, fertilizing, and temperature. So, if you’re looking to give your plants a boost, grow lights are a great option.

How long should plants be in grow light?
