LED lighting on strawberry in greenhouse

My name is Andrea Steffi, and I am a graduate student in the Special Crops Program at Colorado State University. I conducted lehrerin experiments in the greenhouse off-season in 2020 and 2021 to understand whether supplementing LED lighting will increase the growth yield or fruit quality parameters of strawberries. The experiment carried out 3 times of light treatment and 1 time of non-light control treatment.

White fire red low blue light and high blue light LED strips. Each treatment was applied to two different day-neutral strawberry varieties, albion and san andreas. Before starting the experiment, at night, we used an aspect radiometer to measure the light output processed by each LED. Both low blue light and high blue light treatments have higher red photon density, which is called the driving factor of photosynthesis. The effect of treatment on plant growth and fruit quality is analyzed. The soluble solid content (brix) that appears in the weight and yield of a single fruit can be sold as an indicator of sweetness and leaf area.

The experiment was repeated twice during s. In the first experiment, the number of days was shortened, after the winter solstice, the number of days was extended in spring and the number of days in autumn was shortened again. We see an increase in the number of fruits that can be sold and the number of fruits that can be sold. The weight of a single fruit processed by all LED grow light is the highest in high blue light and low blue light, because the weight of fruit San Andreas is higher. Using bricks to measure the soluble solids of berries, we found that the sweetness increased under high blue light treatments, and in all treatments, the worship of ouralbion was generally sweeter than sanandreas. We found that under all LED light treatments, the leaf area increased, especially under low blue light and white far-red light. Sanandreas extended days experiment 2 caused limited response. Supplemental lighting is a key tool currently used by greenhouse growers and researchers.

It shows potential in the off-season and increases the production of high-value crops. The most sensitive scene is to shorten the number of days in autumn in the san andreascultivar du and use supplemental lighting with low blue or high blue wavelengths. These studies show that in shortened days, higher density blue to red wavelengths are added. Supplemental lighting can improve the overall quality of strawberry fruit and plant growth

Marijuana plants should be kept away from the light source for maximum yield

I want to talk to you boys and girls about how far the plants should be from the light source. There is no doubt that no matter what bulb you install, I will say what system are you running besides Marijuana Grow Light? I would say any other HIV system. You want to place plants close to light. When you descend 12 inches from the position, the light source is in the range of 6 to 12 inches. Your light output loses 70% or more. If you are running CFL or Full spectrum led grow light, if the running bulbs are more than six inches apart, you will lose 70% of the light output of the LED and CFL, so in In HID, you want to only be at 12:6 A few inches from the light source between 12:00. I regret to prove this, because I have been using these dual head bulbs and hoods.

Manufacturers and everyone in the industry say that the Space Observer factory is 36 inches away from these two Dublin bulbs, otherwise they will burn your factory well. If your air conditioner is not good, it is difficult for me to plant plants 36 inches away. For every drop of one or two plants, you will find that 30 plants lose one or two drops, and you lose only because of me The plants did not reach the required level, reaching 30 to 60. Some crops have been planted in this location and are already in my tree canopy, so I am about 36 years old, about 24 to 36 inches. My twin engine is now 6 to 12 inches away from me, if you do not have enough air conditioners, then you need to spend some money and invest in your company and get better air conditioners. The first thing I want to say is that I see this problem in 90% of the growth space and the people with whom I talk. You know they don’t have enough cooling capacity and there is room for growth.

A simple window air conditioner can bring in enough cold air to properly cool it down to 6 kW, so it is correct to make a real investment in the air conditioner, and your output will explode, especially when you will notice the triceps. The yield is better and thicker. I mean about its better taste. If you cool the room appropriately, the quality will improve, so please keep a distance of six to twelve inches between the plant and the light source. When maximizing light output, you know that the lighting keeps plants six to twelve inches away. There are other things that will accumulate maximum output. They achieved this goal, but can be used for lighting. Or maximize your lighting. You know that the woman's growth distance must be between six and twelve inches. Hope you like this video, hope it can bring you a lot of benefits, expand your factory scale, increase production, and let you spend a good night. Thank you

Use ordinary lamps as plant lights-LED and energy-saving lamps for indoor plant lighting

I originally needed every plant to grow normally. Of course, natural sunlight is the best, but in winter, there is not enough sunlight. Therefore, one person or another sometimes asks the same question. Maybe the plant grows up and then you see the normal light, or because you have to go to an expensive bank to buy this problem. There is no answer.

In this article, shortwave blue light is provided for her plants. Ordinary bulbs like this have low light output and are very suitable. This is not like planting lights to find short-wave blue light. But we mainly bring back full spectrum LED lights, so LED lights are very suitable for winter. There are also plants growing. It is also supported by other lighting equipment because LEDs generate very little heat.

You may also damage nearby plants, or you may damage them. LED can obtain good energy and consume a lot. In addition to LED lamps, for example, fluorescent lamps or energy-saving lamps are also used to support plant growth. These lights are very important and are called daylight or neutral white. Then you can put them on, which is Dorian style. Buildings are usually only grown in Thailand. The room is very warm. He is also the star of hero clarification. That's it.

These plants are not available in winter, but for me, the reason this plant can flourish is because the extra lighting is very good. Therefore, you will find that there is no need to buy expensive LED grow lights. You can also use regular lights.

If you know which one is correct, hope this article suits you. If yes, please give me a thumbs up.

Central Maine's demand for LED grow lights

 　　I started to grow in 2002 and have been growing in the medical field for the past four years. This means that my partner Benny started working in flower care in Central Maine, Maine. I think the strains obtained from plants can learn a lot in this book. My name is Andy Lee. I am a leaf grower for a social flowering homeowner in Maine. I am the only LED grower I have ever seen in the industry. We see more and more innovators. Participate in the industry, but this is the foundation of HPSkind. The style is constantly evolving, so the trees and flowers grow into many lines.

　　I am doing traditional green crackle. I am studying "Dutch Dragon". There are some hybrids on Indian sapphire cheese, such as OGKush strawberry cheesecake, cherry bomb and so on. The best sourness of the day, we have run more than 50 different strains here, and in the past four years, we have only tested and found LED technology that cannot be used in our system. For example, the energy saved by HVAC can then be used to control the room to a greater extent, which can help us really adapt to various pressures. Before I saw anyone at VANQ Spectroscopy, they were using many different competing companies. We believe that the average price of high-quality LED lights should be about $1,000 higher than the price of things that require fancy money. In this case, you only worry that the things you buy are no longer reliable. There is basically an LED graveyard in my closet. The 3-year warranty on damaged LEDs with VANQ warranty is a good warranty. The radiator on the VANQ is really great, in fact the radiator here is huge.

　　You can tell us that you can save more quality because you can save money. You do not need to replace the bulbs with these diodes. You know that it takes three to five years for them to completely degrade, so you can only get the same effect as the peak lighting performance, and you can indeed get a consistent lighting effect, and you know that the product deviates from the lighting state because of the lighting. This is another thing you need to worry about. The grand plan for growing these plants does require fine-tuning of all other aspects (such as water). Agricultural system, soil system and nutrient level

Greenhouse grow LED grow light research results

The focus of this research is on LEDs in horticultural applications, not only on the energy impact of energy conservation but also on the non-energy benefits of farmers who integrate LED technology into their operations.

We started in a small garden center south of Minneapolis, next to a restaurant. Conceptually, everything in these two locations is produced and raised on a farm 45 miles from Prato, Minnesota.

We have greenhouses, and most greenhouses are dormant only during the year, so we think this is an opportunity to use the facility and extend the growth period. The snow and fields on the ground were frozen, we transferred energy to the inside, and we began to use the greenhouses on the ground more, because the cold shelves and high tunnels made us discover that Minnesota can produce higher quality and higher value for the local Food for 12 months a year, instead of taking it to far away, at least you have the ability to understand your own high-quality food, high-quality food, nutritious food, they know that the exciting thing about LED technology is efficacy Increased In the past three years, about 70% of crop costs have dropped sharply, and in greenhouses led, this is a controlled cultivation method.

Farmers have created new opportunities for the crop environment. When we start to pay attention to energy consumption, especially in winter, when energy costs account for a large proportion of the company, we must have a good understanding of the appearance of these inputs, and then how can we make the most of them maintain high energy consumption. There are obviously many alternatives to high-quality products on the back-end, and if we just start looking for ways to save or change the source, it will have a major impact.

Another aspect of this research area we are studying is the result of growing in a low-income environment. LED lighting. When you compare our high-pressure sodium devices, what I noticed. Under LED lights and LED lights, plants are under high pressure. Growth tends to be faster but not so strong, and the route is not so firm. Under LED lights, you tend to become more compact, but with higher density and stronger rooting. Therefore, I think the quality of plants is actually better and closer to the appearance under LED lights in daylight.

Under high-pressure sodium lamps, the powdery mildew on the LED lighting side is much smaller than that of high-pressure sodium. This shows that I think one person will definitely be healthier and stronger than others. The fact of the disease-resistant plant I think is that you can slightly adjust the wavelength, you can adjust the light according to the specific crop, and you can use different LEDs. There are more blue LEDs and red LEDs. What is the spectrum of sodium? For me, LED lights are undoubtedly the next area I definitely recommend in order to be able to grow crops locally.

This is a real victory in protecting sustainability and enabling our growers to produce and use this new technology locally throughout the year.

 

Which LED or HPS growth lamp is better?

Today, the topic we will discuss is that there has been great interest in this fast-growing indoor horticulture industry. Now growers are polarized on this issue, so we are dealing with two options. After all, both options are very effective. Well, and both will ultimately help us achieve our respective growth goals. Both options have their advantages. We will discuss it immediately. It will depend on you. The grower will decide which option is best for your needs. Therefore, without effort, let’s dive directly and have some fun.
Now let’s start with high-quality old-style HID HID lamps or high-intensity discharge lamps, which is definitely the traditional choice, and growth lamps. These lamps mainly have two growth metal halide lamps and high-pressure sodium lamps, which now have a cold spectrum or blue spectrum The task of the metal halide lamp is suitable for high-pressure sodium lamps for plant growth or heating lamps for high-pressure sodium lamps and is now suitable for the red spectrum of flowering plans. Unless these lights work properly, no one will. The large amount of light produced by these bulbs contains an intensity spectrum suitable for plant growth, but this light intensity comes at a price.
As we all know, HIV generates a lot of heat, which is why other components are often needed in the equipment that uses them. Causes of heat generation. To make them a viable option, these projects now include ballasts to regulate the electrical output from the source hood to wrap the lamp itself, as well as built-in fans and air ducts to cool the lamp. The most common case is to use some type of air The equipment cools the room to the right temperature, and now the original cost of buying all these items and the operating costs of running all these components can make the installation very complicated, which means it may take some time to dial each component in the room The merge work is even, so the final output is temperature. This is ideal for increasing the variables we need to consider. The ambient temperature of the room containing the room continues to increase, the air volume of the fan, the cooling capacity and settings of the air conditioner, and of course the lighting itself, once a good balance is achieved, you will get good results, but this still allows you to increase all The energy consumption of these ingredients will hardly cause you any inconvenience. The HIV setting requires that the bulb be changed from a metal halide bulb to a high-pressure sodium bulb from the plant growth period to the flowering period, but a replacement bulb must also be purchased each time. Because of their short life, these lamps rarely increase.
Now, relative to new technology growers, talking about LED light-emitting diodes or LEDs is a type of light. New technology growers are polarizing this technology. LED users who have experienced a sharp decline and made great achievements have benefited greatly from it. But other people refuse to try or have different experiences when testing them. Some of the reasons for this situation are the hesitations we often encounter, because growers may be satisfied with the light they use. If the light does not break, please do not fix it at a level, it makes sense, but When you consider all the inefficiencies of HID lighting, you must realize that this is not an ideal solution. Another reason we encountered is that growers tend to classify all LEDs into a single category. As HID tried, we can all understand the trend of doing this, but the reality is that this idea is not consistent with the facts. There are too many differences between a leading company and later companies, and it is easy to compare the power design differences between the products they produce and the spectral diodes between apples and oranges. Amplifying the drive current for a placeholder, to name a few, will greatly affect its effect. If growers buy improperly by buying cheap imitation LED lights, then your precious plants will perform poorly on the whole and blame all LED technology on the poor harvest, which is easy to understand because how to induce consumers to buy inferior products , These products have a lot of technical information about night LED companies and competitive lighting technology companies, that is to say, it is difficult for buyers to do this.
Know who or what you can trust, we will try our best to help you eliminate the haze in this video. From a technical point of view, those LEDs that have entered the market have obvious advantages. Their useless power is cooler than traditional bulbs. Longer lifespan, this alone is enough to influence your decision, but this technology needs to be applied in the right way to have a truly positive impact on your plants, not all LED growth lamps are manufactured And, there seem to be many such plants in the market that seem to ignore the high-quality LEDs that factories really need to thrive. The advantage is that these diodes can be targeted.
Photosynthesis spectrum Including visible light and invisible light. LED panels can contain a certain number of diodes in each color or wavelength, so they can be perfectly adjusted to absorb the exact proportion or number of these wavelengths to form the spectrum that plants will absorb and utilize. This means there is almost no wasted light, you can get a very efficient growth system, you can get amazing quality results by providing your plants with exactly what you need, and you don’t need to look at the spectrum comparison table to understand How to get the spectrum.
The most perfect spectrum harvested from our factory is a waste-free spectrum. By observing the comparison table between the LED and HID lighting options, we do see a lot of light emitted by the HID bulb, but a closer look shows that there is a lot of light energy in the green and yellow areas. Although the spectrum rarely uses plants, it is the least used. The photosynthesis in this area is caused by hyperspectral and HIV bulbs, but the actual measurement units required by plants are completely unreliable, so it is easy to ignore plants. Operating costs continue to increase because they appear on your energy bill once a month, so if you need to be like me, you usually pay these costs as you grow, but in reality, these costs can be very Big, affect your productivity and profitability. ROI, you cannot ignore these costs.
The average life of LED lights is about 50,000 hours. It works 12 hours a day. It has been running for more than ten years. Now, it is a typical HID bulb. It takes about 7 to 10,000 hours, which can make your growth time up to one and a half years. Last but not least, LED lamps have a lower operating temperature, which frees you from the growing demand for other cooling components. need. This room made us talk about not wanting to talk about Monday’s return on investment. Now, when you compare the results of LED and HIV growth, you may get similar results. When talking about profits, this is probably the most common mistake in measuring success. Now, when considering operating costs and listed output, you want the average power per watt to be less than 1 gram of factory products from the leading HID brand, while the average power of LEDs from leading Cob LED grow light manufacturers is about 1.4 grams per watt.
