Grow Light for Fenestraria: Holding Baby Toes Compact
A grow light for fenestraria holds baby toes short and tight. This small succulent needs bright light and dry soil to stay firm.
The short answer
Give fenestraria bright light from a sunny window or a grow light within 12 inches for 12 to 16 hours. Low light makes the leaves stretch and a sudden jump in light can scorch them. Let the soil dry fully between waterings since succulents rot when left wet.

How much light do baby toes need?
Minnesota Extension suggests a bright sunny window for succulents. Iowa State says low light gives tall pale spindly growth in succulents. It also says a sudden move to bright light can leave brown or tan patches.
Move it to brighter light slowly to avoid brown patches.
How close should the light be?
Hang the light overhead. Minnesota Extension suggests cool white or daylight tubes 6 to 12 inches above succulents for 14 to 16 hours a day. Iowa State uses an LED or fluorescent grow light within 12 inches, set on a timer for 12 to 16 hours. Minnesota Extension’s lighting page notes that LEDs do not produce too much heat.

How do window leaves use light?
Each leaf ends in a clear tip that lets light into the leaf. Leave the tips above the soil line.
Minnesota Extension suggests a mix of one part potting soil to one part coarse sand.

Troubleshooting
Pale long leaves: low light. Lower the lamp or add hours.
Brown or tan patches: a fast jump in light. Lift the light and step up gradually.
Soft yellow growth: overwatering. Skip watering until the soil is dry.
