Do clones need 24 hrs of light? This is a common question asked by many new growers looking to produce the best quality plants. And, the answer is not as straightforward as one might think. While some growers believe that clones need 24 hrs of light to develop into healthy plants, there are others who think that clones require less light during their early growth stages.
Clones, like any other plant, require a certain amount of light to produce energy and grow. However, providing too much light can be just as detrimental as not providing enough. This is because clones have a limited capacity to absorb nutrients and energy, and providing too much light can lead to nutrient burn or stunted growth. On the other hand, not providing enough light can lead to leggy growth and weak stems.
The amount of light required for clones varies depending on the stage of growth they are in. During their early growth stages, clones require less light as compared to when they start to mature. Providing 24 hrs of light during the early growth stages can lead to excessive energy consumption and ultimately hamper the growth of the clones. Getting the right balance of light is key to producing healthy and bountiful plants.
Optimal Light Schedule for Cloning
Cloning is a popular method for propagating plant species that is widely used in agriculture and horticulture. It involves taking a cutting from a mother plant and rooting it to produce an exact genetic replica. Light is an essential factor for successful cloning, as it plays a significant role in the plant’s growth and development.
- 24-hour light schedule:
- 18/6 light schedule:
- 16/8 light schedule:
Some growers believe that keeping clones under 24 hours of light will produce more rapid root growth and higher yields. This method is considered beneficial as it provides the plant with a constant supply of energy to undergo photosynthesis. However, constant light exposure can lead to stress and may affect the metabolism of the plant, leading to reduced overall growth and decreased quality.
The most common light schedule preferred for cloning is 18 hours of light and 6 hours of darkness. This schedule allows the plant to have an adequate amount of light to promote photosynthesis, but also gives the plant ample time to rest to avoid stress. The 6 hours of darkness also help to prevent stretching and promote bushier plant growth.
Another light schedule that can be used for cloning is 16 hours of light and 8 hours of darkness. This schedule is commonly used during the vegetative stage of plant growth, but it can also be beneficial for cloning. The longer dark period allows the plant to rest and may lead to more vigorous roots.
Ultimately, the optimal light schedule for cloning will depend on the specific plant species and the grower’s personal preference. It is important to note that clones are delicate and require proper environmental conditions to thrive, including the appropriate lighting schedule. Consistency is also key; any changes in the light schedule can disrupt the plant’s development and potentially lead to failure.
Providing the appropriate light schedule is essential for successful cloning. As a grower, it is important to understand the various options and choose the best one for your specific plant species. Remember, consistency is key, and any adjustments in the light schedule should be made gradually to avoid disrupting the plant’s development.
|Light Schedule||Hours of Light||Hours of Darkness|

Effects of light duration on clone growth
Light is an essential element for the growth and development of plants. However, the optimal amount of light required for clone growth is still a subject of debate among growers. The duration of light exposure affects the plant’s growth, and different light schedules can be used depending on the growers’ preference. In this article, we will discuss the effects of light duration on the growth of clones.
- 24-hour light exposure: Providing continuous light to clones can result in faster growth and better root development. However, this can also cause clones to stretch too much, leading to weak stems and reduced overall plant health.
- 18-hour light exposure: This light schedule is commonly used by growers as it provides sufficient light for clone growth and allows for a brief period of darkness, which promotes healthy plant development.
- 16-hour light exposure: This light schedule has shown to be effective in some cases, but it may lead to slower growth and longer vegetative periods in certain strains.
It is worth noting that the light intensity also plays a crucial role in clone growth. Providing a high-intensity light source can result in faster growth and better yields, but it can also damage the plant if the light is too close or too strong. On the other hand, providing low-intensity light can result in slower growth and smaller yields, but it is less likely to cause damage to the plant.
To better understand the effects of light duration on clone growth, we have compiled a table showcasing the differences in growth rates between clones exposed to different light schedules.
|Light Duration||Average Growth Rate|
|24 hours||0.8 inches per week|
|18 hours||1 inch per week|
|16 hours||0.6 inches per week|
It is important to note that these growth rates may vary depending on the plant strain, the light source used, and the growing environment. Therefore, it is essential to monitor the plant’s growth and adjust the light schedules accordingly to ensure optimal growth and yields.
Importance of Dark Period in Cloning
Cloning involves the propagation of genetically identical plants. This is achieved by taking cuttings from a “mother” plant, which is usually in the flowering phase. These cuttings, also known as clones, are then placed in a rooting medium to encourage the growth of roots. Clones need adequate light to photosynthesize and grow, but they also require a dark period. Here’s why:
- Root Growth: During the dark period, the plant’s focus shifts from photosynthesis to respiration. This means that the energy generated by the plant is directed towards root growth instead of leaf production. This is crucial because robust root growth is needed to anchor the plant and absorb water and nutrients efficiently.
- Stress Relief: Plants, like humans, need rest to mitigate stress. A break from photosynthesis gives the plant a chance to regenerate and repair damaged tissues. This is especially true for clones that undergo significant trauma when cut from the mother plant.
- Timing: Dark periods are essential for regulating plant growth and development. By controlling the amount of light the clone receives, growers can manipulate the plant’s growth cycle. Clones that receive more than 24 hours of light can experience stunted growth or even die due to exhaustion.
The optimal dark period for clones is between 6 and 18 hours, depending on the specific strain being propagated. This period can be regulated using timers on grow lights or by placing the clones in a separate dark room during the appropriate hours.
In conclusion, a dark period is as crucial to clone growth as light. By giving clones adequate darkness, growers can encourage robust root growth, relieve stress, and regulate the plant’s growth cycle. It’s important to remember that each strain has unique needs, and growers must adjust the duration of the dark period as needed.
|Benefits of Dark Period in Cloning:||How to Implement a Dark Period:|
|1. Promotes root growth||1. Use a timer on grow lights to regulate light exposure|
|2. Relieves plant stress||2. Place clones in a separate dark room during appropriate hours|
|3. Regulates plant growth cycle||3. Adjust the duration of the dark period as needed|
Keep in mind that finding the right balance of light and dark is crucial for healthy clone growth. By understanding the importance of a dark period in cloning, growers can optimize plant growth and yield.
Impact of Light Intensity on Clones
When it comes to cloning cannabis plants, light intensity plays a significant role in the growth and development. It is essential to provide proper light intensity to ensure healthy and robust clones. High-intensity light can lead to stress and stunted growth, whereas low intensity can also negatively impact the plant’s growth. Here are the effects of different light intensities on clones:
- High Light Intensity: Cannabis clones exposed to high light intensity can get stressed, leading to stunted growth and yellowing of leaves. High light intensity can also cause photobleaching, resulting in a loss of chlorophyll and reduced photosynthesis efficiency.
- Low Light Intensity: Low light intensity can result in lagging growth, stretching of internodes, and weaker stems. It can also lead to fewer branches and longer periods to mature.
- Optimal Light Intensity: An excellent balance of light intensity can lead to healthy and robust clones. It is recommended to provide 2000-3000 luxes of light intensity for clones.
It is important to keep light intensity constant and provide the same level of light throughout the clone’s growth cycle. Any significant changes in light intensity can result in shock and negatively impact the clone’s health and growth. Clones are delicate and require a consistent light environment to ensure successful growth.
Below is a table that illustrates the effect of light intensity on cannabis clones:
|Light Intensity (Lux)||Effect on Clones|
|1500-2000||Stunted growth, yellowing of leaves|
|2000-3000||Optimal light intensity for healthy growth|
|Above 3000||Photobleaching, loss of chlorophyll|
Providing proper light intensity is crucial to ensure healthy and robust cannabis clones. Optimal light intensity helps the clones to develop a robust structure and establish a healthy root system, which is essential for the growth and development of the plant in its vegetative stage.
Light color and spectrum for cloning
The light color and spectrum used for cloning plays a significant role in the success of the process. The ideal light spectrum for clones is blue light, which has a wavelength range of 400-500 nm. Blue light spectrum promotes vegetative growth, which is most suitable for clones.
- Blue light: As mentioned earlier, blue light is essential for cloning success. It helps in developing a strong root system and increases the growth rate in the vegetative stage. Too much blue light can cause stunting or delayed growth, so it is crucial to maintain the correct intensity and duration.
- Red light: Red light has a wavelength range of 600-700 nm and helps in the flowering and fruiting stage. It has a low impact on clone growth but is necessary for mature stages. Too much red light will induce early flowering, and too little will cause delayed flowering.
- Full spectrum: Some growers use full-spectrum lighting that contains blue, red, and green light. It provides a more balanced spectrum and can be suitable for clones depending on the strain.
Light intensity also plays a vital role in cloning success. Clones require less intense light than mature plants. Too much light can damage or burn the delicate leaves of clones. It is recommended to keep the light intensity at 400-600 PPFD (Photosynthetic Photon Flux Density) and be decreased as the clone grows.
Growers can use table light intensity and duration while cloning:
|Light Type||Intensity (PPFD)||Duration|
|Blue LED||400-600||18-24 hrs/day|
|Red LED||400-600||18-24 hrs/day|
|Full Spectrum LED||400-600||18-24 hrs/day|
Using the correct light spectrum for cloning and maintaining the right intensity and duration can lead to a successful cloning process. Experienced growers can experiment with different color spectrums to find the optimal spectrum for their particular strain of plant.
Using Supplemental Lighting for Clones
When it comes to cloning cannabis plants, they require a specific amount of light to grow properly. However, clones don’t need the full 24 hours of light that mature plants require. In fact, it’s best to give clones some darkness to rest and recover.
- Most growers recommend giving clones 18-20 hours of light and 4-6 hours of darkness. This is because clones need less light than mature plants, and too much light can actually stress them out and stunt their growth.
- However, there are some instances where supplemental lighting may be necessary for clones. If the natural light in your growing space is insufficient, you may need to provide additional lighting.
- Supplemental lighting can also help speed up the cloning process. By providing more light, you can encourage faster rooting and growth.
If you do decide to use supplemental lighting for clones, it’s important to choose the right type of light. LED grow lights are a popular choice for their energy efficiency and spectrum control.
It’s also important to keep the temperature in your growing space in mind when using supplemental lighting. If you’re using high-wattage lights, they may generate additional heat that could stress out your clones. Make sure to monitor the temperature and adjust accordingly.
Overall, using supplemental lighting for clones can be a useful tool for growers. Just make sure to follow best practices and be mindful of your clones’ specific needs.
|Can speed up cloning process||Too much light can stress out clones and stunt their growth|
|Can provide additional light in areas with insufficient natural light||High-wattage lights can generate excess heat|
|LED lights are energy-efficient and offer spectrum control|
Light cycles for specific plant species cloning
Cloning is a popular technique among gardeners and growers that allows them to reproduce their favorite plants with exact genetic copies. However, cloning requires careful attention and a conducive environment to achieve success. One vital factor to consider when cloning plants is the amount of light they require.
While some plants prefer to be under specific light cycles for cloning, others respond better to different cycles. Here are some of the commonly cloned plant species and their ideal light cycle:
- Cannabis: Cannabis plants require 18-24 hours of light during the cloning phase for speedy growth and healthy development.
- Tomatoes: Tomato plants grow best with 12-18 hours of light during the cloning process.
- Basil: Basil clones require approximately 12-18 hours of light per day for optimum growth and healthy roots.
Knowing the specific light cycle your plants need will help you provide the best possible environment for cloning success.
It is worth noting that while light cycles may vary depending on the plant type, it is recommended to provide aseventy percent humidity during cloning processes for all plant species to prevent dehydration. Here is a table summarizing the cloning light cycles for some common plant species:
|Plant species||Light cycle||Humidity level|
By following the recommended cloning light cycles, you can set your clones up for success and ensure they grow into strong, healthy plants.
Lighting methods for indoor cloning
When it comes to indoor cloning, lighting is one of the most important factors to consider. Proper lighting ensures that your clones receive adequate light for photosynthesis to occur, which is essential for their growth and development. Let’s take a closer look at some of the common lighting methods used for indoor cloning:
- Fluorescent Lights – Fluorescent lights are a popular choice for indoor cloning because they are affordable and energy-efficient. They don’t emit as much heat as other lighting methods, so you don’t have to worry about your clones overheating.
- LED Lights – LED lights are a newer technology that has gained popularity in recent years. They are energy-efficient and produce very little heat, making them a great choice for indoor cloning. Many LED lights are also adjustable, so you can customize the spectrum to suit your specific cloning needs.
- High-Intensity Discharge (HID) Lights – HID lights are known for their intensity and are often used in large-scale indoor growing operations. These lights produce a lot of heat, so they require proper ventilation to prevent your clones from overheating.
When selecting the lighting method for your indoor cloning, there are a few factors to keep in mind. Consider the size of your growing space, the number of clones you plan to grow, and your budget. Additionally, think about the spectrum of light that your clones need for optimal growth and development.
Now, the big question is, do clones need 24 hours of light to grow? While clones don’t necessarily need 24 hours of light to grow, they do need a consistent amount of light each day. Many growers opt for a 18/6 light cycle, meaning the clones receive 18 hours of light and 6 hours of darkness each day. This schedule mimics the natural light cycle of the sun and allows the clones to rest and recover during the dark period.
|Light Method||Light Cycle||Advantages||Disadvantages|
|Fluorescent Lights||18/6||Affordable, energy-efficient, low heat||Limited intensity|
|LED Lights||18/6||Adjustable spectrum, energy-efficient, low heat||Higher cost upfront|
|HID Lights||18/6||High intensity, good for large-scale operations||Produces a lot of heat, requires proper ventilation|
Ultimately, the lighting method and cycle you choose will depend on your specific needs and preferences. Remember to regularly monitor your clones and adjust your lighting accordingly to ensure they are receiving optimal conditions for growth and development.
Natural vs Artificial Light for Cloning
When it comes to cloning, light is one of the most critical factors that affect its success rate. The majority of clones require a minimum of 16 to 18 hours of light per day. But, do clones need 24 hours of light? This article will discuss the difference between natural and artificial light for cloning and answer this commonly asked question.
Before we dive into whether clones need 24 hours of light, let’s first look at the difference between natural and artificial light for cloning. Natural light is produced by the sun and is what plants experience in their natural environment. This form of light changes intensity and spectrum, depending on the time of day, season, and weather. On the other hand, artificial light is produced by lamps and is consistent in spectrum and intensity.
- Advantages of Natural Light
- provides a full spectrum of light that mimics the sun
- offers variations in intensity and spectrum throughout the day, allowing plants to adapt to changes in their environment better
- Advantages of Artificial Light
- allows for light to be delivered on a consistent schedule
- makes it easy to control the spectrum of light delivered to the clones
- allows for clones to receive the necessary amount of light no matter the time of year
Now, let’s answer the question, “do clones need 24 hours of light.” Generally, clones do not require 24 hours of light but do require a minimum of 16 to 18 hours of light per day. Providing clones with more than 18 hours of light can lead to diminished results, lower yields, and plant stress. Clones need a period of darkness or a light schedule with a consistent rate of photoperiodicity to grow optimally.
|Hours of light per day||Cloning Stage|
|18-24 hours||Rooting stage|
|16-18 hours||Veg stage|
|12 hours||Flowering stage|
While clones do not require 24 hours of light, it is crucial to provide them with the correct amount of light depending on their growth stage. The table above shows the recommended amount of light per day for each cloning stage. By following this schedule, you can ensure optimal growth and development for your clones.
In conclusion, natural and artificial light both have their advantages, but it is ultimately up to the grower to choose which is best for their specific needs. Clones require a minimum of 16 to 18 hours of light per day, but not necessarily 24 hours. By providing clones with the correct amount of light, growers can ensure optimal growth and yield from their clones.
Adjusting light schedules for successful clone rooting.
When it comes to successfully rooting clones, adjusting light schedules can be a key factor in ensuring success. Here are some tips and tricks to help you adjust your light schedules for maximum clone rooting potential.
