Q.Red and blue light bulbs for plant growth
I have several plants that I am wintering inside. the shortage of sunlight is causing them to Wither can a regular blue and red household lightbulb help to keep them alive until late spring planting. How long should I leave them in the artificial light. Can I use a red and blue light Bulb at the same time? I am currently using a combination of red and blue on a rosemary plant lavender and several other herbs.
