1. Plants have strong adaptability (unlike animals, animals are migratory), the first generation and the second generation will show differences, so in this case, the requirements for light on the planting environment will also be different.
2. Only by mastering DLA can we discuss planting technology, and stable planting technology can realize planting industrialization.
3. To make a plant lamp, you must first know what “light” is. The response between light energy and receptors is what needs to be studied for plant cultivation.
Fourth, the spectrum is not very good, only very suitable. On the basis of certain light quality conditions, light quantity > light quality, that is to say, the spectrum is the same, and the planting effect will be improved after increasing the power. However, one of the advantages of LED grow lights is energy saving. For practical applications, LED grow lights can make plants absorb more efficiently and waste less energy.
5. The market of plant lighting in 2018-2020 is mainly affected by the rapid growth of the hemp market, and the trend of the professional market is also developing from Indoor (indoor) to Greenhouse (greenhouse).
6. The equipment has parameter attributes, and it is not reliable to evaluate the quality of the plant lamp by self-feeling without talking about the parameters and the light color.
Seven, the difference between DLA and DLI:
(1) DLI – Dose of sunlight – Geographical location
(2) DLA – Artificial Light Dose – Light Source Design
Calculation formula: DLA=0.0036 X PPFD X light period (hour) [unit: mol/m2d]
8. Spectral technology of plant lamp – planting technology spectral technology (core technology) – light quantity of planting conditions – PPFD of canopy
9. The brand-only theory of lamp bead chips is not the healthy development direction of plant cultivation. After the lamp bead efficiency reaches 2.0, blindly pursuing the improvement of parameters will not be of great significance to planting.
Light Quality – SPD, Spectral Shape
Photoperiod – bright period, dark period
Dosage – DLA
10. The energy supply method has changed the traditional planting process, and planting quality and planting cycle have become the goals.

11. Three elements of planting technology spectrum technology:
Germplasm (Object) – DLA (Energy) – Environment (Conditions) Same germplasm, same environment, few spectral components are good. Save energy! Very energy efficient!
12. Light has no color, and white light does not exist.
13. The absorption of sunlight by plants only accounts for 13%, and the green light band in the sunlight is very sufficient. If it is a greenhouse fill light, when designing the plant light, the spectral composition can not contain the green light part of the band. In this case Also save energy.
