Greenhouse lighting: planting lights and agricultural products

Winter in Canada can be long and dark. The lack of natural light throughout the year hinders the production of winter greenhouses. As a result, greenhouse growers need to use auxiliary lighting to provide high-quality products. Consumer hopes are not the same throughout the year. When an alternative light source is provided to crops, the growth and growth of crops will be different.

 

Greenhouses currently use high-pressure sodium lamps or HPS lamps. Their investment cost is very low, but you cannot adjust the quality of the light. They may become very hot, reaching 300 degrees. This means that if the light gets too close, the plant may burn. Light-emitting diodes or LED grow lights are the latest technology. They provide higher quality light with customizable intensity, direction and color settings. Their surface temperature is also lower than that of HPS lamps, so they can be used inside the crop canopy.

 

Canadian agricultural and agri-food scientist Xiuming Hao from the Harrow R&D Center and Cao Rong from the Guelph Research and Development Center are busy using a new hybrid lighting system, HPS can illuminate the top of the crop canopy and LED lighting inside the crop canopy. The Canadian Department of Agriculture and Agri-Food is one of the main organizations researching global greenhouse vertical lighting. The results show that the new system can increase the yield and nutritional value of greenhouse crops. They found that by using an optimized hybrid lighting system, suitable spectra can be emitted at different heights, and the vegetable yield of cucumber plants is twice that of traditional greenhouses. Twenty times more than the ground! They also studied the effects of greenhouse LED lights of different colors on antioxidants in vegetables. Blue light increases the content of polyphenols, helping plants protect themselves from insects and diseases.

 

On the other hand, red light will increase carotenoids, which is very beneficial to plant growth and leaf health. The results of these studies may enable Canadian greenhouse growers to overcome the Canadian winter and enter the entire 12-month production cycle. This will enable them to produce fresh vegetables throughout the winter. Satisfy consumers' demand for high-quality local products throughout the year. This will also make them more competitive, because they will be able to stand out, and winter imports will be able to expand their influence in the international market. With the help of our Canadian agricultural scientists, the sun will never stop shining on Canadian greenhouse growers. At the right time, at the right time, everything is extraordinary.

How close is the distance to keep the LED grow lights

Hello, my name is Joshua. Today we are going to talk about the distance of placing the plant growth lamp on the plant to be found. Starting from the general range, try to see if the manufacturer of the lamp provides information and how far away is. If your lamp is 100, you should keep the lighting (if you don't follow these general tips). You want to keep it between 8 and 12 inches. Anything below 100 watts is not really useful for any type of actual growth.

 

Maybe you get a plant by a window or something, you need to give it a little more light power than 40 watts, but if you want to grow the light completely, you need at least 100 watts, so 100 watts 8 to 12 distance 200 to 399 inches, This will give you 400 to 600 between 12 and 20 inches which is about 20 to 27 inches, and then 600 to thousands to no matter how bright you can get, you need at least 3 feet or more if you are using one that is far away from the top of the plant Matters needing attention reflectors like mylar I have come back here, you want to give your plants a little extra height and monitor them very carefully, because all this reflected light entering your plants may make you incomprehensible Take a little further than you need, and then move in instead of as you want, you need us to love our plants, so you think more light means more love, but you don’t want to burn your plants , So it always starts to be cautious about its distance. It’s good then move it down, wait a few days, and then move it down again. You can find your little sweet spot, I let my light come closer once I sprout, My plants will sprout to simulate the spring sun’s tendency to move them farther. This is not really necessary, but I prefer to make sure that I get the germination rate and possible, so you do after setting the general range a The next thing in general height is that you have to closely monitor the plants, they will tell you that you are exactly what they need, so the common symptoms of plants do not get enough light to make the leaves yellow and drip, hindering the growth of the leaves. And dim colors, so I have almost no problems like mine. When I set the correct height, there is always too much light. I dialed everything, and of course the plants grow light upwards, and then as they grow, They are burned, so I don’t really have a good example, but if you want to make sure it’s not as long as your plant, because once it grows long, it’s within reach.

 

 

It becomes fragile to recover. It may have a weak plan based on it, and then weaken the rest of the plan to stay healthy. It seems crazy, so continue to make sure you are looking at the plant to make sure you are now Give them enough light to shine on the headlights, this is an example of cucumber plant growth. Too much light makes you unable to see the leaves are scorched. I believe you can look good on the camera, but these skills are restricted Yes, you will be burned to death. The patches you can see here have some spots burned off on leave. Okay, they are very crisp, a bit like it is really crisp, like this, you want to be careful A little bit and imagine that you are sunburned. I am glad you know that you have been sitting on the beach for too long in the sun. You are sunburned. This is the same reaction that plants will have to you. This is what you are looking for. I think most growers will tend to just because of this problem rather than problems like this. How powerful LED grow lights and all growing lights, etc. are now, plants tend to grow into lights and get sunburned, so you want to see if To something like this, please adjust the lighting adjustment in advance. The three ways to give plants are of course. You keep the light close to the plant, move it to a farther place, you give them less light, and you get closer to it. , You give them more numbers two. You can also set a timer. I use a timer here, it will automatically turn off and turn off the lights according to the 16 o’clock and 8 o’clock schedule.

 

 

If you can’t move upwards like in my shelf system, only a certain distance away, you can keep it, and then you can adjust how long to keep them at any time so even if the LAT light touches the leaves and you, you only keep it It stayed there for four to six hours, which is equivalent to a day full of light. Just in general, I don’t want to try any math or whether this is completely equivalent, but the point is that you can start a timer and reduce the amount of light the plants get, or You can add or remove the reflective sheath. I use a lot of polyester film just because I like my growth lamp to be the most efficient. I know that you have to pay for electricity like I want to make the most of it and control how close I can put the lamp. Knowing that it can save time and energy, so I can not only reflect on my tray, but also reflect on the back wall, because it is just a concrete wall, it absorbs light, so if I can reflect some of the light than I Useful, and then I can use to reduce energy, so I strongly recommend that you use a reflector system in your products and get the best energy for your lighting. Another reason I use reflective film is because the light cannot penetrate the roof like Like sunlight, sunlight travels millions of miles, so it’s not a big deal to penetrate the sun a few inches down through the canopy of something, but it’s a big deal for grow lights.

 

Because you are only emitting light and putting a foot or two on the ceiling of these inches, it may be difficult for the light to penetrate, so I put the reflective polyester film here to reflect it back to the bottom of the canopy, so all of these can get very good Good light sources, even shaded leaves can get good light, so thank you for discussing with me how to put the light near the plant. The comment section tells me if you burned the plant like I did. Tell me if you did it Correction, did you make further adjustments to put the timer there, or you added or removed reflective film, thank you for watching.

Orchid-Thinking about the setting of LED plant growth light

Hello, friend, I know this is very different from my opinion. I usually start to play the video because at night, I am asked to show you how to set up the micro lights at night to provide me with extra orchid lights so that they can grow better, so I think I should share my settings .

 

Basically there are 3 400W LED grow lights, and each LED light has at least 15 high-power LED lights. I bought them from China and there is always one in the middle, but I got two aspects from me. I recently went to China. Their price is lower than the price I don't hate me, but less than $10. They are doing well, partly because China is famous for semiconductors. China's LED industry is also very mature, so it has many manufacturers. They cooperate with many manufacturers. Chinese manufacturers, so that they can truly produce high-quality LEDs. But you know the price is reasonable, so I didn't buy it from Amazon or any western online retailer.

 

LED planting lights are actually related to China Channel. I mainly turn on these LED lights before going to bed. The time I get off work or go home in the gym is when I actually turn on the LED lights on the ceiling of that grout room. Therefore, if I open it, you can say that it is really bright. The wattage LED bulbs on the three-story ceiling are really bright, but if you turn them off, you will know that it is significantly darker, but I put three LEDs on top. The growth lamp still performed well. The growth space illuminates this growth space. Now I like my settings.

I prefer these round ones because they can be moved to the laboratory or to the right. It depends on whether you know which jobs I think require special lighting. In order to make them move without being fixed, they are all like clips, so I can actually use it to clip on the side. But I only wrote this, not only put them on the top and middle layers without lining, but for the third layer here, I did have a lining at the beginning, and this lining on each shelf, but I took out the top and The reason for the lining of the middle shelf is because it is winter here, even in Sri Lanka, so I want to make sure that I don't limit the ability of the orchids on the shelf to get more light through the windows during the day.

 

Do you know I have a liner here? It does not absorb as much sunlight as it does without a shelf, but another one. The problem is, I switch to one of the three switches on the back, and then everyone has the correct switch. I can easily turn them off or on in the morning, but I have to use a belt to secure the switch so that I can easily find the position of the switch and then the air purifier. This is the hospital level. I also bought it from China. In fact, it is no more than a year old and it works well. I know that sometimes it becomes very sensitive, but I noticed that the terminology is different. I have less allergic reaction to the groom or the whole air, I can say that it does make a difference, as I mentioned, this is that every room in some hospitals in China has such a ward, because micrograms are actually smaller than ordinary wards , So I know this is enough.

You know this is enough to purify my air growth space. I'm not. I really don’t know if an air purifier can really help orchids grow better, but every time I enter this room, I feel the air is better. Maybe it’s just me thinking, but you know that it didn’t cause a lot of Energy, so I’m doing this just in case, when I help these orchids in some way when I’m not at home, I did close the orchids by my side in order to protect the energy. For safety reasons, I don’t want to open none Any of my appliances. Now, when I return to China, this is just a short announcement in the flower market, we are talking about I met a lot of orchid lovers and learned what hydroponic orchids are becoming more and more popular in Asia, but this is because of babies People in the early days did not know much about water culture, full water culture or half water culture, so I will start to make videos about water culture based on my Chinese experience to grow orchids to help my Chinese-speaking friends in Asia. Learn from experience, you can communicate and learn from each other, and continue to lead you into my orchid growth journey.
