Know How Much Light Your Specific Plant Need

Different plants need different intensities of light. Some are low light indoor plants, some are medium light indoor plants, and the remaining are bright light indoor plants. They need the required intensity to grow and offer fruitful results. Therefore, indoor growers need to understand how much light their indoor plants need. Before we dive into the types of plants that require low, medium, and bright light, we need to understand what low, medium, and bright light are.

Low Light: Low light is said when there is no direct sunlight. The plant remains away from the natural sunlight, and inside the indoor grow room, it is away from the grow light. This could be achieved by a small fixture of 10-50 watts, and the PPFD can be 50-150 µmol/s/m2.

Medium Light: Medium-light also means no direct sunlight, and the distance between the light fixture and plant is a bit less than the previous case (low light). The PPFD for this light ranges from 150 µmol/s/m2 to 250 µmol/s/m2.

Bright Light: Bright light refers to direct sunlight. It is also called High Light. The light fixture, in this case, is quite near to the indoor plants. The PPFD is around 250-450 µmol/s/m2.

Now, let’s have a look at the types of different indoor plants. 

Low Light Indoor Plants

There is a wide range of low light indoor plants, but some of them are,

  • Aspidistra Elatior (Cast Iron Plant)
  • Peace Lily
  • Lucky Bamboo
  • Mass Cane (Dracaena Massangeana)
  • Pothos
  • ZZ Plant

Light Measurement For Indoor Plants: PAR Or Lumens?

For indoor plants, we need grow lights to mimic the sunlight. These lights have utmost importance as they are responsible for the growth of plants by providing the required spectrum of light. Thus, you need to purchase grow lights with care. While buying a grow light for indoor plants, the most important thing that comes to mind is the output of the light. A grow light is evaluated on the basis of its output.

You will see PAR, lumens, or both on the specification, and this is where beginners get confused. It is important to understand PAR and Lumens to determine whether the grow light is suitable for your plant or not. 

Lumen is the SI unit of luminous flux. It is actually for humans because it is related to the light perceived by the human eye. Our eyes can only see the visible range of white light, which is 400-700 nm in wavelength. However, the white light also contains other radiations, including UV and IR. Lumen specifies the range of the light that humans can see. It does not tell what plants perceive.

For plants, there is a special unit, which is PAR. It is an acronym for Photosynthetic Active Radiation. It represents the light/radiations that plants use for photosynthesis. The spectrum of light that we see through the common eye is a bit different than what plants need. We see almost all radiations playing an equal role in the spectrum. In contrast, plants do not use all radiations in the spectrum equally. For instance, the least useful radiation for plants is yellow, while humans have a great impact of yellow radiation on eyes. Moreover, blue light is the most fruitful light for plants. It is clear that PAR and Lumens are different. PAR is for plants, and Lumens is for humans.

Thus, while selecting the grow lights for indoor plants, you need to consider the PAR value.

Usually, both values are mentioned in the specification, but PAR has more importance. You need to select the light that has a suitable PAR according to your indoor plants. PAR is mearsured in PPF (Photosynthetic Photon Flux) that quantifies the number of plant-usable photons emitted by a light source. Its unit is µmol/s (micromoles per second), and you will find this value in the specification of authentic grow lights. You might also encounter another metric, which is PPFD. It is a Photosynthetic Photon Flux Density that represents PPF per unit area. This also helps in understanding how much the PPF the grow light fixture can provide in a unit area. Its unit is µmol/s/m2 (micromoles per second per square meter).

Signs Of Too Much Or Too Little Light-Part II

According to our last post, when plants receive too much or too little light, they show some signs. For a plant grower, it is important to keep an eye on these signs and act accordingly before anything worse happens. We’ve shared 3 aspects that showing signs of too little light in the last post. Let’s start with the rest ones.

4) No Flowering

If you have indoor flowering plants, then they won’t give you flowers in the case of low light. It is because the plant does not have enough energy to produce flower buds. Thus, if you have noticed fewer or no flowering, you need to check the light level.

5) Leaf Fall

The leaves on the plants may fall if they are not getting enough light. The chlorophyll in the leaves assists in photosynthesis, but when the light is lower than the requirement, the plant cannot produce food. The leaves may fall from the plant as they cannot get enough energy to survive. In normal cases, the leaves fall from the plant at a certain age, but if you notice something unusual, it is a sign of too little light. 

6) Bending/Leading Towards Light

It is noticed that the plant bends towards the light source if it is receiving too little light. It is difficult to notice this sign, but you will also see other signs with it.

7) Smaller Leaf Size

Every plant has a tendency to grow a certain size of leaves. In the case of low light, the plant is deprived of energy, and the size of the leaves becomes shorter. You will start noticing this sign if the plant has been receiving too little light for a long time.

Signs Of Too Much Light

Too much light also imposes a bad impact on plants. It can kill your plant, and most of the time, it makes it dry, and the plant cannot carry out photosynthesis. There are only a few signs to detect this issue in plants.

1) Fading in Color

The color of the leaves will fade with time, and if this issue persists for a long time, you will see bleached leaves. This is a clear indication your plant is receiving too much light. The leaf or a part of the leaf might also get burned or scorched.

2) Lesser Life of Flowers

In the case of too much light, the flowers will not live a longer life. You will first notice the contraction in flowers, and then they will die soon.

3) Wilted Leaves

Due to excess heat and light, the leaves bend and become limp. This is also known as leaf drooping.

In a word, it’s important to keep an eye on these signs and ensure that plants are receiving the right amount of light they need. For other instructions, contact us aokairuisi professional team for an answer!

Signs Of Too Much Or Too Little Light-Part I

Light is a necessity for plants, especially indoor plants because it acts as a catalyst in photosynthesis, and without it, the reaction is not possible. As we all know, both too much and too little light are unfavorable for plants. Whether the plants are in your backyard or inside your house (indoor plants), it is important to ensure that plants are receiving the right amount of light they need. 

When plants receive too much or too little light, they show some signs. For a plant grower, it is important to keep an eye on these signs and act accordingly before anything worse happens. 

Signs of Too Little Light

For indoor growers, this problem is quite common. The indoor plants are often deprived of the light they need. There are some symptoms and signs that can indicate your plant needs more light.

If you see one or more of these signs, you must increase the light exposure. 

1) Change in Color

The first thing that the grower can notice is the color of the leaves.

The leaves are green due to the presence of a green pigment called chlorophyll. This green pigment appears green as it absorbs all colors except green, which is why it gives off the green light. Chlorophyll is present in the chloroplast. It has the utmost importance as photosynthesis takes place because of it. Without the process of photosynthesis, plants cannot produce their food.

We all know that plants need light to carry out photosynthesis. If the plant is receiving low light, then the process of photosynthesis will be slow, and the plant will not be able to produce sufficient food. Due to scarcity of food/energy, the plant cannot produce green pigment (chlorophyll). Consequently, there will be a change in the color of the leaves.

Finally, the green leaves will turn pale green. If the scarcity continues, it will change to yellow and then white. In the case of variegated plants, the change of color is a bit different. As they are normally white (can be another color like pink), their original color is the sign they are receiving the right amount of light. If the color of their leaves turns green, then they are receiving little light. It is because they are deprived of energy, and they try to get more energy by increasing the amount of chlorophyll in the leaves.

2) Leggy Stems

When plants do not receive enough light to produce energy and food, they cannot make new leaves. In this case, only the stem grows using the available energy/food. The stem becomes leggy, and there are fewer leaves on it. It means there will be more spacing between the leaf nodes and leaves. If you notice that the spacing between the nodes is increased and the plant is becoming thin and long, you should increase the light. 

3) Wet Soil

Wet soil is another sign of too little light. Plants need light and water to make their own food. They absorb water from the soil and convert it to energy by reacting it with carbon dioxide in the presence of light. If there is little light, the plant cannot carry out photosynthesis. Consequently, it does not use water in the soil, and the soil remains wet for a long time.If you notice the soil remains wet longer than usual, your indoor plants need more light. 

We will be sharing more information about this in the next article, if you have questions or inquiries about grow light, please contact our professional aokairuisi team!

How To Improve The Output Of Greenhouse Vegetables

1.Water It Properly

Keeping adequate water is an important factor to ensure the normal growth of vegetables. Choosing a proper time for water and reasonable water amount is an important measure to improve the yield of vegetables, especially in winter. Because the temperature in the greenhouse is lower in winter, the water absorption and evaporation are slower, which is easy to cause adverse effects on the moisture content of the air in the greenhouse and the growth of vegetables. The following points should be paid attention to: first, the watering time should be selected when the temperature is higher, usually after 11:00 a.m. of the day and before 2:00 p.m. During this period, the temperature inside the vegetable greenhouse is higher, which will not cause the occurrence of frost damage. It is also possible to choose water deep in the ground at higher temperatures for irrigation. Pay attention to observe and measure the temperature throughout the shed. Generally, the temperature is a little higher on the sunny side. Water more, and water less in the colder areas. In consideration of the influence of weather, water more on sunny days and less on rainy days is due to high air humidity and low pressure, which is not conducive to water absorption and easy to cause frostbite. The best approach is to use drip irrigation. Not only can achieve the goal of water conservation but also can reduce the humidity in the greenhouse environment to keep dry, conducive to the growth of vegetables and water absorption.

2. Reasonable Fertilization

The right amount of organic elements is also necessary for the growth of vegetables. To improve the yield of the greenhouse, organic base fertilizer should be selected as the first choice. Organic base fertilizer can not only improve the content of soil microelements, but also promote the reproduction of beneficial microflora in the soil, change soil structure, and enhance the storage and supply of organic fertilizer and water by soil substrates. When fertilizing, it is best to pay attention to the principle of a few times, to leave a certain amount of time for vegetables to absorb fertilizer.

3. Reasonable Ventilation

In winter, though the temperature is low, ventilation is unavoidable. Reasonable ventilation is to improve the fresh air in the greenhouse, reduce the carbon dioxide content, and reasonable transmission of light, so that the vegetables have a great degree of photosynthesis, prevent the occurrence of diseases such as yellow, weak light disease, adverse to the growth of vegetables

4.Illumination

It is well known that light determines the growth rate of this vegetable. However, in winter, due to the influence of climate, the time of light is short, the days are short and the nights are long.At this time, it is necessary to choose some expected lights to the vegetables such as LED grow lights. Aokairuisi has been engaged in the production of LED grow lights for more than ten years, and the product quality is widely popular by customers.

So when we grow vegetables in winter, we need to pay attention to many aspects.

Problems Should Be Avoided When Using LED Grow Light

Many people around the world are growing marijuana at home, whether for entertainment or medical purposes, although some of them do well and produce good products, for others, they don’t work well. In this article, we will provide you with the most common things you should be aware of when using LED grow lights so that you can grow healthy plants and avoid any unnecessary hassles. This information is very relevant to beginners.

1.The Wrong Distance Between Lamp And Plant

If the leaves closest to the light begin to brown, you will know that the plant is taking too much heat. If some of the leaves begin to curl, it may also indicate that the plants are too close to the light. Besides, excessive light or insufficient light may also be due to the light being too close or too far from the plant. There is no optimal standard for setting the distance but it is recommended to place the LED 12 to 18 inches from the plant and adjust the appropriate distance according to the growth rate of the plant. (you’re always welcome to contact our aokairuisi professional team for instructions). Another important thing is to occasionally rotate the flower pot to prevent uneven illumination. Causes the plant to tilt too much.

2.Insufficient Lighting

Planting areas of different sizes need to choose plant lights of different powers, think about how many plants you are planting, and how many LED lights you need to properly illuminate them. You should also know the brightness of the light you are using. Light is the most important factor in plant growth because it triggers photosynthesis processes. If you use ordinary incandescent lamps, it’s unlikely to grow strong and healthy plants. Therefore, for best results, we recommend using a full spectrum aokairuisi LED grow light. Designed specifically for this purpose, they have the ability to provide illumination in the precise spectral range required by the factory.

3.Do Not Protect And Maintain LED Grow Lights

LED grow lights are your friends and important investments, so you need to keep them in a safe place. They bring a lot of benefits to the evolving process, and a little maintenance and preparation can save you a lot of trouble. There will be another blog about maintenance from aokairuisi team in the near future, if you’d like to learn more about it, you can contact us at any time.

4.Incorrect Lighting Usage

Some growers may forget to turn on these plant lights when they are too busy. On the contrary, or forget to close them, this may sound insignificant, but the wrong arrangement is likely to adversely affect the growth of plants. In fact, cannabis requires approximately 18–24 hours of illumination during the vegetative phase and 12 hours of illumination during the flowering phase.

In fact, indoor cannabis cultivation saves us a lot of trouble, but we still need to consider many factors such as room temperature, air circulation, soil, nutrients, plant genetics, etc. during the growth of plants. A little more patience and care with the plants, plants will give us unexpected returns.

Can LEDs Affect The Taste Of Vegetables

There is a widespread misconception that the taste of vegetables is solely based on genetics of the plant species and cannot be enhanced by cultivation techniques or environmental conditions. That would be true in a scenario where other cultivation parameters were universally normalised. However, this is rarely the case when it comes to indoor vegetable production facilities.

How are the fruits and vegetables in the greenhouse different from the fruits and vegetables in the natural environment? Natural fruits and vegetables grow under the sunlight, while fruits and vegetables grow under the LED grow lights in the greenhouse. To solve the puzzle, the first thing is to understand the working principle of the LED grow light, it is the principle of fully simulated sunlight on plant photosynthesis, in accordance with the law of plant growth needs sunlight, using led grow light instead of sunlight to plant growth and development environment of a kind of lamps, so under the sun and the growth of fruits and vegetables under LED grow light irradiation is the same, can be eat, so taste better or not?

In the natural environment, fruits and vegetables should always be prepared to fight against natural disasters, such as wind, rain, snow, frost, fog, and disease and insect poisoning. The ability to survive is stronger, but it often leads to deformity or insect infestation, thus affecting the taste of vegetables and fruits. On the contrary, fruits and vegetables in the greenhouse do not have to experience the wind and rain, and the led grow lights can provide different light according to the growth state of the plant, so that the plant is always in the best growth environment, and it is perfect in both appearance and internal taste.

Compared with the sunlight, led grow light has the biggest advantage of artificial control. According to different plants and different growth stages, it is equipped with the most suitable lighting environment. LED growing lights can also control the intensity of light, making the photosynthesis of plants more active and controlling the light cycle, making the photosynthesis of plants longer. It was reported that in the arctic research camp of Germany, researchers used LED plant lights to try out a variety of vegetables such as tomato, cucumber, and kohlrabi in the cold region.

So there’s no doubt that the vegetables that come out of the led grow lights are not only healthy but also taste better! Want to try?

When It Comes To LED Grow Light,Forget LUMENS

How Many Lumens Do The LED Grow Light Produce?

Many growers ask us about lumens of our full sepctrum led grow lights. Lumens are a measure of how bright a light will appear to the human eye, not how well a LED light will grow plants. Although a good way to measure metal halide, high-pressure sodium, T5, and CFL lights, lumens will not accurately describe the growing ability of the LED grow light. This is because LEDs are not maximizing brightness. Rather, aokairuisi led grow lights maximize the portions of the light spectrum that help plants in photosynthesis. For example, the red, far-red, and infrared diodes are critical in a LED grow light. However, these colors do not emit bright light and would have a low lumen measurement. Although lumens are a good metric to measure the brightness of a light, it doesn’t convey meaningful information about the growing capability of LEDs.

Aokairuisi led grow lights are designed with a weighted average of the optimal wavelengths needed for the photosynthesis of plants. Aokairuisi lights maximize the portions of the light that the plants need most, such as the red and far-red wavelengths, and minimize the portions that are used less. Aokairuisi also supports customizing the spectrum according to the characteristics of different plants, customization for growers to play the best role of plant growth lights and save costs for them.

How to Measure LED Grow Lights

So, how should we measure LED grow lights? The strength or intensity of the light can be measured by the total wattage of the LED grow light. The higher the wattage, the more intense the light will be. The coverage area of a grow light is another good measure of its strength. Another measure is the PPFD and PPE( also called EFF). If you’d like to learn more details about these, contact aokairuisi professional lighting expert, we will answer and support you.

Aokairuisi led grow lights maximize the power consumed by the light to provide the highest yields per electricity consumed. Grow healthier plants, with robust flowers with more trichomes. Aokairuisi grow lights grow plants with more flavor, aroma, and potency.

Why We Need Grow Indoor＆LED Grow Light

A successful grow story begins with professional led grow lights.

Indoor farming technology has more advantages than the traditional farming method. Possible to grow more type plants all year round without regard to the weather, insects, and diseases.
True spectrum engineering helps you to grow best plants with a perfect appearance and flavor.

Get More Harvest

Quality and high yield are related to temperature, humidity, nutrition, but also lighting of plants. Daily light integral and photoperiod are the critical factor in growth duration. Lighting of plants stimulates or suppress vegetation, flowering and fruiting. When grow indoor, extreme weather, insects and diseases are not longer a threat for users. Much possible to get more harvest and harvest better plants no matter what you grow.

Healthy Grafting

A healthy grafting needs true and sufficient level lighting. You can increase your successful grafting rate and reduce your electric usage with professional grow lights.

Cost Saving

Traditional plant growing requires a large area of land. When you adopt indoor plant growing and use professional LED plant grow lights, you can replace traditional planting way with vertical agriculture to save land area and cost. At the same time, indoor planting and led grow lights can make your plants mature faster and yield higher.

In conclusion, grow indoor will help you to get more harvest and at the same time save cultivation costs, advanced indoor farming technology is helping people and society to progess.

Advantages Of LED Grow Light Compare With HPS Lamp

Grow lights are used in applications where there is either no naturally occurring light or where supplemental light is required. Horticultural LED systems and the spectral science they have made possible have already revealed some amazing effects, including using light alone to create bigger yields per plant; producing more marketable crops overall; and changing the wavelength of light to change the flavor of foods. For these reasons and others, including the ones detailed below, LEDs are on their way to replacing legacy lighting systems in many new and newly renovated growing operations. In addition, LED technology is popular for scientific application to get the best results with high-efficiency photosynthesis and healthy growth duration.

Avoid High Temperature Damage To Plants

High temperature damage, is a plant physiological injury caused by too high temperature. This will lead to deterioration of plant protein, damage of biofilm structure, disorder of metabolism in the plant, and abnormal phenomena such as leaf burning, plant wilting and flower falling off.

According to the law of energy conservation, it is found that the ability of LED and sodium lamp to convert electric energy into light energy and heat energy is different. Using the same energy, the LED plant growth lamp as the cold light source will produce more light and less heat, while the sodium lamp of the hot light source will produce a lot of heat and less light while lighting.Therefore, compared to these two lights, LED plant growth lamps not only save energy, but also convert more energy into light energy, providing effective radiation for plants, and effectively avoid plant “high temperature damage” and help users reduce planting risks.

Longer Service Life

LED uses solid semiconductor chip as the luminescent material, and the light decay is small. The sodium lamp is used to generate arc between the electrodes between the two ends of the arc tube, and its life expectancy is shorter than that of the LED plant growth lamp.

Rich Wavelength And Good Light Filling Effect

As an important factor of plant growth, light plays a very important role. It is found that the spectral energy distribution of sodium lamp can be roughly divided into red orange light, yellow green light and blue violet light (a small amount). The LED plant growth lamp can emit monochromatic light with narrow light wave, such as red, green, blue, orange, etc., and these monochromatic light can be mixed. For example, the mixed wavelength LED light source can promote the growth and development of lettuce, basil and other seedlings and roots, shorten the flowering and fruiting cycle of plants, and increase the accumulation of sugar and starch in sugar beet; The red and blue spectra with different proportions can meet the requirements of different stages of plant growth, coloring, flowering and fruiting.

To sum up, LED grow light has more advantages than sodium lamp in performance, service life and effect, reduces the cultivation cost, and is more worthy of consumers to buy.
