What kind of light is the best for indoor gardening and what are the cheapest options?
I have a small indoor seed starter/green house and it is standing in the warm part of the house (65-70 degrees). I would like to grow some herbs (rosemary, basil, majoram, thyme, oregano and start some lavenders for planting out later). I know it is difficult to start rosemary from seeds but the others should be fine. Which lights are the best ? Can I use an old Christmas light (white light not the one with many colors) How many hours of light is sufficient?
