For Indoor, family, greenhouse cultivation, do you encounter
the following problems?
1. Succulent plants grow leggy, difficult to have bright color.
2. Flowering time late and short ; Flower color is dark.
3. Plant grow slow.
4. Fruit is not Sweet enough.
5.To enlarge profits, you want to sell the fruits of the same period earlier.
6. Common cultivation on of vegetables have high nitrite con

Light intensity and photosyntheic rate.
A: At night time, leaves have no photosynthesis, only release
carbon dioxide and do respiration.
B: With the increase of light intensity, the photosynthetic rate
increased accordingly, when reaching a certain light intensity.
Leaf photosynthetic rate and respiration rate are equal, net
photosynthetic rate is zero, then the light intensity is called light
C: In a certain range, the photosynthetic rate increased linearly
with the increase of light intensity. However, When the light
intensity reached a certain point, the photosynthetic rate did
not increase with the increase of light intensity , This phenomenon
is called light saturation. The light intensity at which point the
photosynthetic rate begins to reach its maximum is called the
light saturation point.
