Conclusion In this experiment I tested different light intensities. I tested a normal fluorescent light bulb‚ a 100-watt light bulb‚ a 25-watt light bulb‚ and a 15-watt light bulb. I was surprised to find that the control plant grew the most at 135 mm. The 100 watt plant grew the least at 0 mm due to the fact that it fried the plant. The 25 watt plant grew the next highest at 120 mm. The 15-watt light bulb grew tall fastest‚ but then slowed down and stopped at 98 mm you would want to use this
