Blue Pothos likes bright, indirect light for the best coloration and growth. It can do well in a low light setting because it is a woodland plant. If you keep the plant under grow-lights, remember to give it at least 8 hours rest in darkness every 24 hours. Pothos plant does best with the soak-and-dry method of watering. Water the plant thoroughly, allowing water to flow through the drainage holes. These tropical vines like a humid setting.
