Do you know these knowledge points of plant growth lamps?

1. The plant lighting market from 2018 to 2020 is mainly affected by the rapid growth of the hemp market. At the same time, the trend of the professional market is also developing from Indoor (indoor) to Greenhouse (greenhouse).

2. The brand-only theory of lamp bead chips is not the healthy development direction of plant planting. After the lamp bead efficiency reaches 2.0, the blind pursuit of parameter improvement will not be of great significance to planting.

3. To make a plant light, you must first know what "light" is. The response between light energy and receptors is what needs to be studied for plant cultivation.

4. There is no best spectrum, only the most suitable. On the basis of certain light quality conditions, light quantity>light quality, which means that the spectrum is the same, and the planting effect will be improved after increasing the power. However, one of the major advantages of LED plant lights is energy saving. For practical applications, LED plant growth lights can maximize plant absorption efficiency and minimize energy waste.

5. Plants are highly adaptable (the difference between animals is that animals have mobility), and the first and second generations will show differences. Therefore, in this case, the requirements for the planting environment on light will also be different.

6. The equipment has parameter attributes. It is unreliable to evaluate the quality of plant lights based on self-feeling without parameters and light color.

7. Plant light spectrum technology-planting technology spectrum technology (core technology)-planting conditions

Quantity of light-PPFD of the canopy

Light quality-SPD, spectral form

Light cycle-bright cycle, dark cycle

Dosage-DLA

8. Only by mastering DLA can the planting technology be discussed, and the stable planting technology can be used to realize the industrialization of planting.

9. The difference between DLA and DLI:

(1) DLI-Sunlight Dose-Geographical Location

(2) DLA-artificial light dose-light source design

Calculation formula: DLA=0.0036 X PPFD X photoperiod (hour) [Unit: mol/m2d]

10. The energy supply method has changed the traditional planting technology, and the planting quality and planting cycle have become the goal.
