Indoor planting is not the same as outdoor planting. In addition to the need to supplement light, other requirements also need to be paid attention to. Sowing requires soil, and then distinguish which plants to plant. It should be noted that generally indoor planting is the cold season, so pay attention to the temperature, otherwise it will affect the growth of seedlings.
First, prepare fertile, well-drained soil and proper regional planning. Then place the seedlings so that they do not interfere with the seedlings, and then play the role of compaction, so that the supplementary light and temperature control can allow the seedlings to grow healthily.
Problems to pay attention to when planting
1. Indoor plants must be planted according to the specifications of specific varieties or hybrid varieties.
2. Compactness poses a serious threat to crops and is the cause of pests and diseases.
3. Make sure to leave a piece of land in the darkest place and place a bucket or water tank for fertilizer or pruned grass. During the fermentation process, carbon dioxide is released, which has a beneficial effect on plant growth and fruit setting.
After the above-mentioned problems about sowing are solved, the most critical plant light will be supplemented. Then how to choose LED plant lights?
Three points to know before choosing LED plant lights:
First of all, we must understand what plant to supplement light? Because different plants have different requirements for light intensity and spectrum, this affects the power selection and spectrum customization of LED plant lights; professional LED plant lights will customize the spectrum according to the needs of different crops at different growth stages, and the spectrum can significantly affect the light supplement Effect.
Understand the area and layout of the supplementary light area, which involves the selection of the size of the LED plant light, the layout and installation, to ensure the uniformity of light and increase the utilization rate, and use the entire space as reasonably as possible without causing regional waste.
Estimate the cost, the cost estimate of the LED plant light is determined according to your planting plants. If you are growing high-value plants, of course the cost of investment will be higher. On the contrary, lower it. In fact, the main thing is to meet the needs of your plants, and the right is the best. You can also find a professional person to help you with quotations and related questions, which will help you choose LED plant lights better.
Choosing LED plant lights can start from these 8 points:
1. PAR
PAR stands for "photosynthetically active radiation". It is a metric used in plants, while lumens are used in humans. So plants don't care how bright your lamps look. PAR in lighting is a wavelength in the visible light range of 400 to 700 nanometers (nm), and plants use this range for photosynthesis or growth.
2.PPF&PPFD
There are two stages related to photosynthetically active radiation (PAR). They are photosynthetic photon flux (PPF) and photosynthetic photon flux density (PPFD).
PPF simply describes the number of photons produced by the LED growth lamp in the PAR wavelength range in one second.
PPF is measured in units called micromoles (umol). You can use PPF to determine if your plant growth light is "strong enough."
PPFD is the number of photons that hit the canopy of a plant in a given second. This is measured in micromoles (umol). The larger the value, the better. The difference between PPF and PPFD is that PPF is the light intensity measured at the light source, while PPFD is the light intensity measured on the surface of the plant.
3. Light effect
Photon efficiency is a measure of how well a light source produces visible light. The unit of efficiency is Joules per second (J/s). If you know the PPF of the light and the input wattage, you can easily calculate the photon efficiency. The higher this number is, the higher the efficiency of the led plant growth lamp to convert electrical energy into photons.
4. LED chip
LED chip is the most necessary and basic aspect of LED plant growth lighting. Therefore, the manufacturing of chips must keep durability and efficiency in mind. A suitable LED chip can hardly appear color inconsistency while maintaining voltage and intensity. Elaborate chips can produce effective and uniform LED plant growth lights, which can support a variety of crops.
5. Spectrum
The spectrum refers to the electromagnetic wavelength of the light generated by the light source to promote plant growth. In order to carry out photosynthesis, plants use light in the PAR (Photosynthesis Effective Radiation) region. The wavelength of this region (400nm-700nm) is measured in nanometers (nm). Red light and blue light are the most critical for plants. Blue represents plant growth stage, while red represents flowering. In addition to red and blue, other wavelengths are also conducive to certain stages of plant growth. Ultraviolet rays help protect plants from insects and diseases, while more infrared rays than normal will make your plants think they are covered by something, so they need to grow taller to get more light. Compared with other wavelengths, green light can penetrate plant leaves farther and deep into the canopy. The ideal spectrum can help accelerate vegetation, increase flowering, accelerate growth, and so on. Whether the light source is an auxiliary light source (such as an indoor) or the only light source also affects which spectrum should be used.
Equipping your indoor plants with full-spectrum LED grow lights means that it can provide all the wavelengths present in natural light. All you need to do is to switch the amount of light the plant needs in different growth stages.
6. Heat dissipation
Although LED plant lights emit less heat than other traditional plant lights, putting many LED plant lights together, they still need a heat dissipation system to keep the body cool at all times. Some of the best LED plant lights on the market have a heat sink to release extra heat. This means that there are no noisy fans, and no power is wasted by powering them.
7. Lighting coverage
Every LED grow light you consider should contain information about lighting coverage. This refers to the area covered by the light falling on the plant, usually in square feet. A good coverage area is very important. Not only the size and lens of the LED grow light determine your coverage area, but also the height of the suspension. The farther the distance between the lamp and the plant, the larger the area, but the lower the PPFD.
8. Wattage
When it comes to the wattage of LED grow lights, this indicator refers to two things. 550w LED light can show that it can really absorb 550w energy from the wall, or it can provide brightness power equivalent to 550wMH/HID growth light. This also has to be selected according to your planting plants. If it is a more light-loving plant, you can choose a higher power.
When you choose the LED plant growth light, you can choose the best LED plant growth light for your plants by taking the above 8 points as the standard. In terms of minimizing power costs while maximizing plant health, the right LED grow lights will bring you the most benefits.
