When taking care of cannabis plants, we think of the time frame, however, light is also considered in the process. It is said that cannabis produces its bud with time rather than light. Buds need consistent light, so shedding it with light is extremely important. Let us determine how long does cannabis need light per day.
Most growers think that 18 to 24 hours is the ideal range of light for auto-flowering plants. Now let us distinguish this two ranges of hours that our cannabis need.
For the18-hour Lighting
Autoflowering cannabis is said that it can survive sunlight for at least five hours a day. However, if you want your cannabis to thrive more and hit the peak potency then produce a heavy harvest, they need 18 hours of light per day. The perfect light for beginners is 18 hours of light and 6 hours of dark.
For the 24-hour Lighting
There are areas in the northern part of the world where they can receive about 24 hours of light depends on season growth. Cannabis is classed as a C3 plant, which means it can absorb Carbon Dioxide during the periods of light for photosynthesis. Theoretically, it can eliminate the need for darkness because they do not need periods of dark to photosynthesis, they have no special features to combat photorespiration.
Both can be ethical for growing your plants, you just have to choose the right time and lighting for your cannabis strain. There are cultivators that most likely to take the middle ground, using the 20-hour light cycle. This, in fact, offers a great deal in growing marijuana.
For autoflowering, you have to take note of the two main stages; vegetative stage and flowering stage. Take it as an analogy of a human being, the childhood stage, and the adulthood stage. Let us break down the two:
This is one of the important stages of the life cycle of your plant. This is the jump start of growing stage of your cannabis which needs more nurturing like a baby. The cycle will make your cannabis plants grow taller and bigger, specifically growing only stems and leaves. You are then able to grow and control the size and shape of your plants using the simple training method. During the entire stage, the plant only produces buds and all, the stems and leaves are more likely to increase. Thus, plants tend to grow very fast, especially when conditions are right relatively to light.
Despite the name itself, this does not literally means starting with the formation of flowers. Flowering only occurs a few more weeks into this stage. It is somehow weird to call it flowering when in fact it does not correlate to when you induce flowers. But rather it begins when the cannabis plant notices a change in light. This is how it knows winter is approaching. Many people misinterpreted that this stage is a change which means a decrease in light. However, the change is measured by an increase in the amount of continuous darkness.
How Can We Acquire Light for Autoflowering Cannabis Plants?
It is already given that we consider the light, we have only limited sunlight that we can organically manage to acquire as we grow our plants. However, there are locations who do not catch enough light depends on the cycle of the season. Another factor is the area, whether indoor or outdoor, still, cannabis needs enough light to yield. There are practical options that we can do, by acquiring light in simpler ways. Autoflowering that varies among marijuana do not rely on a change in light schedule to determine when to flower. The variety of strains will finish their whole life cycle within 2 to 3 weeks regardless of enough light schedule that they are catered.
What kind of Light do Autoflowering Cannabis Seeds need?
In the beginning, sunlight is the only source that we can get to shelter light for our plants, however, in the modern days, more plant growers opted to light technology.
These Types of lights are:
The light technology is called high-intensity discharge, or HID. This type of light comes in two varieties: this can be sodium or metal halide. This types of light are very strong, a little inefficient and only produces a substantial amount of heat. However, if you know how to constrain the heat, they eventually give you a job well done.
As mentioned, since there are space constraints, some growers started using lower-powered and more efficient lights compared to HID. When we say efficient, less electricity is lost to heat and that is more of an actual light is transformed. Such as compact fluorescent lights or the CFL, this is more efficient, small and compact, cheap, and can be available in any common hardware store or supermarket. Cannabis needs a specific light spectrum to produce which we are going to dive into the topic later.
On the other hand, modern light-emitting diode, or LED. This is considered as superbly efficient and at the same time producing a great photosynthetic active radiation. This means that the measure of the quality and intensity of the light spectrum that the plants actually use for photosynthesis. However, this does not mean LED is better than HID and CFL, this only means it fills a huge gap well.
How does the Light Color Spectrum Affect Cannabis Growth?
One that you have to consider is the light color spectrum when growing autoflowering plants. Commonly most growers use more blue lights for the vegetative period and more red lights during the flowering period. In this case, autoflowering strains can use the same principle by using the blue lights before the gender is obvious, then opt to more red lights once you see the action of obvious gender.
Blue light for vegetative stage
This is a radiation with wavelengths ranges from 450 to 495 nm and it affects photosynthesis. This fits the absorption peak of chlorophylls, which do photosynthesis to produce sugars and carbons. It can regulate flowering such as increasing bud size and regulate the timing of flowering. And it can be both essential for the vegetative and flowering stage. However, this can be less effective for driving photosynthesis, this can be manageable as long as you know how to manipulate the usage of the right light combination.
Yellow light for flowering stage
Considered as yellow/orange/red light which tends to produce the best growth and compact buds in the flowering stage. This is also called an amber light, which imitates the reddish light from the autumn sun. it is nearly okay to completely use yellow light for the cycle of life since which encourages stretchy growth and an autoflowering plant to grow fast.
Spectrum is lesser important to yields than the total wattage of the lights. To sort this out, the more the light is given, the more the yields you get.
It is important to know the light that you want for your cannabis. You just have to consider the lighting basics, such as the intensity, the duration, and the spectrum. Choosing your own drill would make your cannabis relatively healthy at your own preference of light. You now have the idea of how to manage the light that your plant needs. Use the options mentioned above as your guide to nurturing your marijuana strains. Dealing with the right light spectrum and choosing the friendly budget gadget would make you and your plants happy.
