What is the difference between direct, indirect, and low-light sunlight for plants?

You might have read plant care guides before to figure out how you can best take care of your plant. You might have looked at the type of light is best for your plant. In these plant care guides, you'll often see terms like "direct sunlight", "indirect sunlight", and "low-light". But what do these terms really mean?

When you know what the different levels of exposure mean, you can help your plant to stay in the level that it prefers. However, it also helps you when you want to adjust the level of sunlight exposure, because your plant might prefer a bit more or a bit less sunlight. It makes teaching others about which level of sunlight exposure helped for you a lot easier.

These are the exposure levels we're going to look at:

Let's learn more about the different levels of sunlight exposure and which plants generally do well in which level!

Direct sunlight levels

Direct sunlight, like the term suggests, means that the sunlight touches the leaves of the plants directly, without something being in the way. This level of sunlight is very bright and you'll generally find this type of light in windows that face west or south, if you live in the northern hemisphere. If you live in the southern hemisphere, you'll find this light in west and north-facing windows. These windows get several hours of bright sunlight during the day, especially in the summer.

There are a few plants that do really well in direct sunlight, like succulents, cacti, sansevierias, and tropical trees like crotons. This direct sunlight is too harsh for most tropical houseplants, because these plants often grow on the ground or on tree trunks. The sunlight that reaches the ground or tree trunks is indirect sunlight, because it goes through leaves and is almost never direct sunlight.

This brings us to indirect sunlight!

Let's move a little away from the window, in the space where you no longer get direct sunlight. This space is still very bright, but the sun rays don't directly touch your plant anymore. This type of sunlight exposure is called indirect sunlight. You get indirect sunlight if you've got a bright spot, the sunlight is blocked, but the space is still quite bright. The sunlight could be blocked by a thin curtain or another plant. It could also just be blocked, because the sunlight doesn't come far enough into the room to directly shine on your plant.

You can find this type of light in a few different spots, like in a room with a thin curtain that has west and south-facing windows, but also in front of windows that never get any direct sunlight. A spot right in front of the window of a north and east facing window, don't get any (strong) direct sunlight, so you can place any "indirect sunlight" plants by these windows without any issues.

This type of sunlight is perfect for most of the plants you can buy, this includes: Monsteras, Alocasias, Palms, Philodendrons, Pothos, etc. All of these plants need a bright space to grow, but get sunburns on their leaves when they're exposed to direct sunlight. We can take a few more steps back into the room to get in the low-light sunlight exposure zone.

Now that we're even further away from a window, we've found ourselves in the low-light zone. Low-light is a spot in your house where the sun can't reach and they're often a little "shadowy". These spots in your house is where to tend to turn on a light to be able to find something.

You might be wondering whether you can actually grow plants in these dark places, because surely all plants need some sunlight exposure. But you can actually grow a few nice plants in these darker places of your house. These plants include: Peace Lilies, ZZ plants, English Ivy's, Sansevierias, and several more. You might have notice that I said Sansevierias again. These plants are plants that can quite literally grow anywhere. They're incredibly tough. These plants thrive in direct sunlight, but tolerate low-light spots. It just won't grow any bigger.

Conclusion

In this plant care guide, we've learned the difference between 3 common sunlight exposure levels: direct, indirect, and low-light. It's useful to know what each of these levels means, because this helps you when you read plant care guides online. Most plant care guides mention these types of sunlight exposure, so now you know where you should put your plants.

Thank you for reading this post! I hope it helps you to keep your plants healthy and beautiful! If you're looking for more guides on specific plants, you can always request a plant guide to get a guide for the plant you have trouble with.
