It is greenhouse gardening. In the industrialization process of plant planting, we call it the planting process. In the case of insufficient sunlight in the greenhouse, supplementary light is inevitable. The spectral parameters of the plant light meet the spectral design requirements and may not guarantee the planting effect and Efficiency. In the artificial light environment, the planting process is the core technology. The planting process is a sufficient condition for planting in the artificial environment. Under the premise of the planting process, the spectral parameters of the led grow light can reflect the planting effect and planting efficiency.
If the LED lamp beads encapsulated by any two packaging companies have the same spectral parameters, the planting effect is the same under the same PPFD plant canopy and the same planting process. It has nothing to do with the brand of the lamp bead packaging company. Bio-optics is the most taboo It is a taboo to superimpose people's preference for the lamp bead brand on the spectral technology.
What needs to be acknowledged is that in lighting products, the brand effect of lamp beads will enhance the customer's sense of identity. That is because lighting is to solve human visual problems. People are used to subconsciously prefer to superimpose the lamp bead brand of lighting products, and this subconsciousness also improves It enhances the buyer’s pride and self-feeling comfort.
but.
Plants will not respond to the lamp bead brand, only the spectral parameters of the lamp bead; people's preference for the brand must not be superimposed on the application of the plant lamp.
Unfortunately, many plant lamp manufacturers (including beginners in plant cultivation) put too much energy on the brand of lamp beads, so that they forget the magic in the substrate and nutrients, and forget the ability to regulate the planting environment parameters. Priority, forgetting that horticulture is a complex professional discipline, entering into the thinking mode of only spectral parameter theory, ignoring what is the core technology of plant cultivation.
Only the spectral parameter theory only shows the lack of knowledge of planting technology.
My suggestion is to use LED lamp beads with excellent cost performance and focus on the cultivation substrate deployment and high-quality genetics. The effect of spending money on planting technology is far better than spending on led grow light. This is my advice to avoid Only the spectral parametric thinking traps itself in the accusation that it cannot solve the customer's planting effect.
Recently, the phenomenon that a certain brand of lamp beads need to wait in line for supply is really incredible. You can consult professionals in the horticulture discipline, listen to their ideas, and be a plant lamp product company. Put the technology of agricultural people in the first place. The two cognition, you have already lost the first step.
There are three principles of spectroscopy technology:
1. There is no best spectrum, only the most suitable.
2. Light quantity takes priority over light quality.
3. With the same planting effect, the less spectral components, the higher the photosynthetic efficiency of the spectral design.
In the continuous development of plant light spectrum technology, led plant grow light can practice new high-efficiency spectroscopy technology every year, that is to say, the technical cycle of plant photosynthetic efficiency improvement of spectral design is less than one year, and good spectral design ultimately serves the planting cost Plant cultivation usually does not reflect the performance and quality of similar industrial products. The price is the dominant factor. For cannabis lamps, the increase in the price of the lamp is not equivalent to the output and quality of the plant. The output of hemp The improvement of quality and quality can be obtained more easily through the planting process, and does not require excessive investment.
The spectral parameters of plant lights can be considered from the following aspects:
1. The QE value of domestic plant lamp beads has reached or exceeded foreign lamp beads, and the cost performance is excellent.
2. Choose lamp beads whose junction voltage is lower than 3.0V to reduce power consumption.
3. Learn to reduce the driving current to obtain high QE, the effect is obvious.
4. At all times, the priority of planting technology should be placed before plant lights to reduce blindness.
5. The QE of the plant lamp is greater than 2.2umol/J, and its planting effect and efficiency basically depend on the planting process, which is the thinking of experts.
6. Know how to use the radiation heat transfer mechanism to control the PPFD of the plant canopy. This technology needs to be studied again, and its effect is much better than blindly increasing the QE value of the plant lamp.
7. The comprehensive energy-saving technology of the plant lamp is better than the improvement of the energy efficiency of the lamp, and reducing the planting cost is the development direction of the plant lamp.
LED plant grow light spectrum technology aims at serving the planting process. Without the goal of planting technology, plant light spectrum design is not technical.
Finally, someone will raise the issue of light decay index. Here we need to clarify a restriction. The application of plant lights is restricted by the photoperiod. 30,000 hours should meet the light decay index. That is the 5-year working period of plant lights. Spectroscopy technology The improvement cycle of planting efficiency is basically less than one year, just understand this reason.
