Does gomphrena need darkness to germinate?
Provide plenty of light on a sunny windowsill or grow 3-4 inches beneath fluorescent plant lights that are turned on for 16 hours a day, off for 8 hours at night. The plants grow taller when the lights are raised. Incandescent bulbs will heat up too quickly, so they won’t work for this process.
If you want to grow plants indoors, you will need to use a grow light that is at least 10 watts per square foot (W/m2) or more. If you are growing plants outdoors, grow lights should be no more than 5 watts/square foot or less. Grow lights that are too bright or too dim can cause the plant to overheat, which can damage the roots and leaves.
