 This is to prevent the occurrence of algae and dirt.
3.Rock wool is made in contact with the air. Roots are easier to absorb oxygen moderate.
4.Light facilitates optimal photosynthesis with light energy and color of an LED is controlled. This also will be given the amount of light that was
 in the height growth of LED lights can be changed.
Q.Is it may be how seeds sown?
A.Wrap 3 grain seeds to a hole of about 3-5mm depth to rock wool.It becomes easier seed sticks when wet with water and the tip of the toothpick.

③There are three of the appropriate temperature.
