Umbilical hernia repair. Umbilical hernia repair is surgery to repair an umbilical hernia. An umbilical hernia is a sac (pouch) formed from the inner lining of your belly (abdominal cavity) that pushes through a hole in the abdominal wall at the belly button. You will probably receive general anesthesia (asleep and pain-free) for this surgery.
Light provides the energy plants need to make the food required for them to grow and flower. Plants are the only organisms able to use the energy from light to produce sugars, starches and other substances needed by them as well as by other living organisms.
Most plants will require about 12-16 hours of light per day. They also require at least 8 hours of darkness each day. Start by setting the timer for 12 hours of light and 12 hours of darkness and adjust the light time upwards if your plant does not appear to thrive.
