When it comes to indoor cannabis growers, whether you are a personal grower or a commercial grower. LED plant lights play an important role in planting. However, for commercial cannabis growers, the requirements for LED grow lights may be different due to different planting purposes, planting environments and budgets.
What are the factors for the best LED plant lights for commercial cannabis cultivation?
1. Spectrum
Although the spectrum of LED plant lights is very rich and meets the growth needs of plants, we still have to identify those spectrums that are not suitable for growing cannabis, such as too much red light, too much blue light, and insufficient infrared light. Because marijuana needs a more balanced broadband full spectrum to obtain ideal growth results.
The best spectrum is customized according to the needs of hemp, the ratio of light quality, and the spectrum can be adjusted, so that every growth stage of hemp planting must be adjusted to meet the required spectrum of each stage, which is also the best for hemp Grow.
2. High parameter requirements
In addition to spectral requirements, we also require other parameters to be as high as commercial cannabis cultivation requirements. Like wattage, PPF, average PPFD, efficacy, etc., because hemp is a light-loving plant, the requirements for supplementary light are very high, and the benefits of commercial hemp cultivation are the most important, so other aspects must be met.
Power High power can meet the light intensity required by hemp and more photon flux.
The PPF determines how many effective photons the cannabis obtains in the LED plant light.
PPFD determines how effectively your cannabis uses photons, and the more evenly distributed the better.
Efficacy, higher efficacy means you can get more photons with the same electricity bill.
For commercial cannabis growers, it is most cost-effective to choose high-power 1000w LED plant lights. The average PPFD is preferably above 1000 μmol/m2/s, even as high as 1500 or 2000, because commercial cannabis facilities have carbon dioxide enrichment systems , Plants can use higher levels of light for photosynthesis. In small individual planting tents, higher PPFD higher than 1000 wastes energy, because most individual growers do not have such a complete CO2 enrichment system, let alone precise control of humidity, temperature, nutrients, etc.
3. Selection of accessories
Commercial cannabis cultivation facilities basically have to operate every day to provide a year-round production for the cannabis market. In this case, your LED plant light must have a very sturdy design. LED plant lights are composed of several main parts that have the greatest impact on durability.
LED chips, top chips include brands such as Samsung, Osram, Lumileds, Cree, etc. These top LED chips have a life span of more than 50,000 hours and a light loss of 10%.
LED drivers, top drivers include MEAN WELL, Inviter, etc. The best drives usually offer a warranty of up to 7 or even 10 years.
The heat sink, which depends on the choice of the LED plant light manufacturer, but the larger the collective surface size, the better the heat conduction. The operating temperature should not exceed 60 degrees Celsius to obtain an L80 life span of at least 5 years.
4. Waterproof and heat dissipation
The heat generated by high-power LED plant lights will be more correct. If it is an indoor environment such as a greenhouse or a greenhouse, it is easy to cause air inefficiency and poor heat dissipation, and the growth of cannabis is related to the carbon dioxide content in the air, so keep it Air circulation. At the same time, we must pay attention to the waterproof, the LED hemp plant light must reach the waterproof level of IP65.
5. Warranty
The warranty period of LED plant lights should be at least 5 years. If manufacturers really have confidence in their quality and their products are made with the highest quality materials and processes, then they claim that it is safe for 5 years.
LED plant lights commercial cannabis planting supplement light tips:
(1) Different types of plants are planted reasonably and arranged in accordance with natural rules. For example, plant plants in the northern hemisphere. It is best to follow the principle of high in the north and low in the south, so that all plants can be evenly illuminated, and try not to shade between plants;
(2) At the same time, reflective measures can be taken in the greenhouse to improve the effective utilization of light. When erecting the rack, use reflective materials. In addition, all the brackets do not need to be upright at 90 degrees. Keep the middle brackets upright, and the north and south brackets are slightly Tilt, this can increase the light utilization rate by 5--10%, and it can be reused by plants.
(3) Cleaning the roof of greenhouse planting regularly clean up "roof garbage", otherwise the transparency is not enough, it will have a great impact on the light and temperature in the shed, which will affect the photosynthesis and respiration of plants, and ultimately affect the yield and quality of plants .
(4) Reflective measures can be taken around the greenhouse, which can reflect a large part of the scattered light back and be reused by plants;
(5) Using LED plant lights to fill light, on the one hand, the light distance can be appropriately shortened. Generally, when buying LED plant lights, they will be purchased according to the installation area and the irradiated area of the LED plant lights. The irradiated area can be appropriately shortened to increase plants in a reasonable range. Fill light.
With the increasing demand for cannabis in various fields, not only commercial cannabis has been developed, but indirect LED cannabis plant lights have also been further developed. The main factor of commercial cannabis plants is the supplementary light of LED plant lights. Only with sufficient light and light can cannabis grow better and achieve an excellent cannabis planting effect.
