I set my little dolphins on the east-facing kitchen windowsill years ago. Every morning they glow a soft green when the early sun slides across them. That gentle light lasts an hour or two. Then the glass falls into shade for the rest of the day. The hard afternoon sun never reaches that spot. I noticed the leaves stay plump and bright there, with no brown edges and no faded patches at all.
No, string of dolphins do not need harsh direct sunlight. The string of dolphins light needs come down to plenty of brightness without the burn. You want to give them bright indirect light for most of the day. A short stretch of soft sun is fine on top of that. Too much hot, direct sun does real damage to those fleshy little leaves.
Here is the technical side you should know. NC State Extension lists this plant as a fan of bright indirect light indoors. Outdoors, it wants 2 to 6 hours of gentle direct sun. That soft morning exposure feeds the plant without cooking it. Strong midday and afternoon sun is a different beast. It heats the leaves past what they can take. You end up with succulent sun scorch on the surface, and burned leaves never bounce back.
Where you set the pot is what counts the most. An east-facing window is the easy win for you. The light there is bright but the sun stays mild. Does your brightest window face south and get hot? Pull the pot a few feet back from the glass. The rays spread out before they land on the leaves. A sheer curtain softens that hot light too. When your natural light is weak, a grow light helps a lot. Run it 10 to 12 hours a day and your plant stays happy through dark winters. My own dolphins ride out our gray months under a small grow light, and the new growth comes in tight and green.
Let the plant tell you when the light is wrong. Leaves that turn bleached, pale, or browned are your scorch warning. That means you should move the plant to softer light right away. The damage shows up first on the side that faces the window. Once a leaf burns, it will not heal. A quick move saves the rest of the plant for you.
Too little light causes the opposite trouble for you. The stems grow long and leggy. The gaps between the leaves get wider. The cute dolphin shapes flatten out and fade away. A plant that reaches and stretches toward the window is begging you for more light. Slide it closer to the glass or add a grow light. The new growth tightens right back up after that.
Light also shapes how your plant looks day to day. Good bright light keeps the leaves a firm, full green and the stems packed close. The little dolphin curves stay sharp and easy to spot. A plant in a dim room loses that crisp look fast. The color goes flat and dull, and the leaves sit far apart on thin stems. So the right light does more than keep the plant alive. It keeps your dolphins cute, plump, and worth showing off on the sill.
Aim for that sweet middle ground and you are set. Pick a spot with steady bright light and just a little morning sun. That keeps the leaves firm, green, and shaped like the tiny dolphins this plant is named for. Skip the blazing afternoon window and you sidestep the worst burns. Bright but soft is the whole rule. Follow it and your dolphins will swim along just fine.
