  • I've always thought that gravity doesn't play any role. The top soil is warmer than the soil below the seed. It grows towards the warmer soil, then once it sprouts and begin photosynthesis, grows towards light.

  • These are the videos that should hit in millions, not the "Charlie bit me," "Lady Gaga," or Avril Lavigne's song's.

    Anyways, I'm still not convinced as to which light do plants grow towards, because man-made lights do not have the same energy or not sames as the sun's. Sun emits Microwave, gamma rays, ultraviolet rays, while our synthetic lights are only "white light," with less energy.

  • those kids knows so much..no kidding
