What is the best science experiment plant?

Does sunlight or artificial light make plant grow faster a good science experiment project plz read bottom?

• I have to do a science experiment project for the last day of school and i was wondering if this is a good topic does sunlight or artificial light make plant grow faster a good science experiment project or Which candle brand stays light up the longest or does a light color candle say let up the longest or dark color candles

• Answer:

  Well, depending on which type of artificial light you use, you get different ranges of the electromagnetic spectrum, including spikes at certain wavelengths, whereas the sun emits a greater range. Plants absorb most efficiently in the reds and blues of visible light, so artificial light may be lacking in the best wavelengths that a plant can utilize. It sounds like an interesting experiment, but you might want to try more than just the common incandescent, for example I use mercury bulbs for my lizard since it produces UV. But plants have to be grown in large batches to see overall trends, because there is always a lot of individual variation, and you may only get really noticeable results if you find a light with a very narrow range of emitted wavelengths of light. I know less about candles, but brand is probably going to make a difference, since there are a lot of things that are put in the candle besides wax that may change the overall consistency. From experience, I would think diameter matters too. hope that helps some.
