The distance of the light provided by the clamp lamp is not invariable. It needs to be adjusted flexibly according to the height of the vegetables.

 

 

The replenishing time should be adjusted flexibly according to the demand of vegetables for light intensity. However, it should be noted that the length of the light should not be extended indefinitely. In case of no precipitation, the scattered light can be seen in the shed and the fill light can be turned off.
