Overall, lots of light and getting dry all the way through between waterings.
Lots of light means, at the very least, sitting on a south or west window. That will provide enough light for “low light” succulents. However, the majority of succulents require full sun outdoors, which is a condition indoors that only be approximated under bright lights on a grow table.
Test soil moisture
Getting dry all the way through means you need to make sure there is no moisture in the soil, even down near the bottom of the pot, where the roots are. The only way to know this is to test the soil moisture. You can use a bamboo kebob skewer, as if you were testing a cake – push it all the way into the soil, pull it up, and run it between your fingers. It should feel completely dry.
Much of the information you read on the internet is incomplete, at best. For instance, “water once a week” (or every other week, or once a month) doesn’t really do it, because there are so many factors that influence how quickly the plant uses moisture. You should test the moisture in your plant once a week, until you’re familiar with what is happening with it.
Do not overexpose with sunlight
“Bright indirect light” usually refers to a window where the sun doesn’t actually shine through. In my experience, this may not be enough light for many succulentsthat are commonly sold in stores right now. For any succulent you buy, you can’t really give it too much light. Don’t worry about some sun coming in the window.
Well drainage soil
“Soil that drains well” is a must for all potted plants, not just succulents. If you buy one that is potted in sphagnum, you’ll need to get the poor little thing out of that into some decent soil. A bag of cactus potting mix, and some perlite (2:1 ratio) will work. Otherwise, leave the plant in the potting mix it’s already growing in.
