Hoya plants, also known as wax plants, are tropical plants that thrive in bright, indirect light. Too much direct sunlight can scorch the leaves, while too little light can cause the plant to become leggy and not produce blooms. Here is a complete guide to Hoya sunlight requirements:

1. Bright, indirect light: Hoya plants prefer bright, indirect light. Place your Hoya plant near a window that receives filtered sunlight, such as a north-facing or east-facing window. Direct sunlight can burn the leaves, so it's important to provide some shade.

2. Avoid direct sunlight: Hoya plants are sensitive to direct sunlight, and exposure to direct sunlight can damage the leaves. Avoid placing your Hoya plant in a location that receives direct sunlight, especially during the hottest part of the day.

3. Provide shade: If your Hoya plant is receiving too much direct sunlight, you can provide some shade by placing a sheer curtain over the window or moving the plant to a slightly shadier location.

4. Avoid low light conditions: Hoya plants require bright, indirect light to thrive. Avoid placing your plant in a location that receives low light, such as a dark corner of the room. If your Hoya plant is not receiving enough light, it may become leggy and not produce blooms.

5. Provide consistent light: Hoya plants prefer consistent light conditions. Avoid moving the plant around too much, as this can cause stress and damage to the leaves. If you need to move your Hoya plant, do so gradually over a period of several days to allow the plant to adjust to the new light conditions.

6. Use grow lights: If you are unable to provide enough natural light for your Hoya plant, you can use grow lights to supplement the light. Use a full-spectrum grow light that is designed for indoor plants, and provide the plant with 12 to 14 hours of light per day.

In summary, Hoya plants require bright, indirect light to thrive. Avoid direct sunlight and provide some shade if necessary. Avoid low light conditions and provide consistent light. If you are unable to provide enough natural light, you can use grow lights to supplement the light. With proper light conditions, your Hoya plant can grow healthy and produce beautiful, fragrant flowers.
