Feminized Seeds Light Cycle | Why is it Important for Growth and Yield?

Did you know that the length of time your grow light is on can affect the sex of your cannabis plants? It’s true! By manipulating the feminized seeds’ light cycle, you can influence whether your plants grow into males or females. Feminized seeds are specifically bred to produce female plants, so you can avoid the hassle of having to identify and remove male plants from your grow. In this article, we’ll discuss how to use light cycles to feminize cannabis seeds.

What are Feminized Seeds?

Feminized seeds are marijuana plant seeds that have been specifically bred to contain no male chromosomes. Meaning that every plant grown from a feminized marijuana seed will be female.

Feminized seeds are typically produced by forcing female plants to produce pollen, which is then used to fertilize other female plants. The resulting offspring will be genetically identical to the mother plant and female.

Feminized seeds are popular with many growers who want to ensure their crop is all-female. An all-female crop is often desirable because

    Female plants tend to produce more buds, which is the part of the plant that contains the highest concentration of THC (tetrahydrocannabinol), the active ingredient in marijuana.

Cannabis Light Cycles

Light schedule for cannabis seedling. When growing feminized marijuana seeds, starting with a healthy mother plant is important. The mother plant should be well-nourished and healthy so that it can produce strong and healthy offspring.

The Best Light Schedule for Cannabis in the Vegetation Stage

The best light cycle for vegetative growth is 18 hours of light and 6 hours of darkness. It will encourage the plants to produce more flowers and buds. Some do so well in the 20hours of light and 4 hours of darkness light cycle. Twenty-four hours of light or darkness cycle is not the best for cannabis plants.

The roots of cannabis grow during late night and early morning when the lights are off. The leaves and stems grow during the day when the lights are on. If you give your cannabis plants too much light, they will grow more leaves and stems and not as many roots.

When transiting to the flowering stage, the best light schedule for growing cannabis plants in the flowering stage is 12 hours of light and 12 hours of darkness.

When Does the Flowering Light Cycle Start?

The flowering phase begins when the plant receives 12 hours of uninterrupted darkness by using a black curtain or by covering the plant with a black sheet.

It Signals to the plant that it is time to begin producing flowers. The plant will then begin to produce buds which will open and bloom into flowers.

Once the plant has been in complete darkness for 12 hours, you will then need to provide it with 12 hours of light. The best way to do this is by using a grow light. By providing your plant with a consistent light cycle, you will encourage it to produce feminized seeds.

Indoor Marijuana Plants Light Cycles

When growing indoors, you will need to control the light cycle to produce female plants. The process of controlling the light cycle is called feminization. Feminized seeds are produced by manipulating the light cycle so that the plant only produces female flowers.

There are a few ways to go about feminizing your marijuana seeds.

  • One method is to use a product called Silver Thiosulfate (STS). STS is a silver compound that interrupts the flowering period, causing the plant to produce only female flowers.
  • Another method is to use a gibberellic acid (GA3) treatment. GA3 is a plant hormone that prevents the formation of male flowers.
  • You can also purchase from seed banks that sell cannabis seeds. Feminized seeds have been treated with STS or GA3 so that they will only produce female plants.

Marijuana Plants Types

There are many different types of marijuana plants, each with its unique characteristics. Therefore, when choosing a plant to grow, it is important to select one that will suit your specific needs.

Light Cycle for Vegetative Cannabis Outdoors

Photoperiodic Plants

These photoperiod plants require a specific light cycle to flower.

Plants grown outdoors will naturally follow the seasons, with shorter days and longer nights in the autumn and winter months. However, in the spring and summer, the days are longer, and the nights are shorter. This changing light cycle triggers the plant to begin flowering.

You will need to change the light cycle to 12 hours of light and 12 hours of darkness to flower your cannabis plants. Be sure to give the plants at least three weeks in the vegetative stage before changing the light cycle, as this will allow them to grow strong and healthy.

Outdoor Light Cycle Door Control

To control the light cycle outdoors, you need to use a technique called screen of green (SCROG). It involves training the plant to grow horizontally along with a screen or netting. It is especially useful in areas with shorter days.

Outdoor Light Cycle Door Control

To control the light cycle outdoors, you need to use a technique called screen of green (SCROG). It involves training the plant to grow horizontally along with a screen or netting. It is especially useful in areas with shorter days.

Light Spectrum for Plants in the Vegetative Stage

All plants need light to grow, but different plants have different light requirements. In general, cannabis plants do best in a full-spectrum light, which mimics the sunlight.

This type of light is available from fluorescent, LED, and HPS lights. Fluorescent T5 lights are the most energy-efficient and produce very little heat, making them a good option for small grow spaces.

Even though they are more expensive, LED grow lights last longer and use less electricity than HPS lights. On the other hand, HPS lights produce a lot of heat, so they need to be used with ventilation and cooling systems.

To get the best results, growers experiment with different types of light and see what works best for their plants.

What is the Best Light Cycle for Feminized Seeds?

The best light cycle for feminized seeds is 12 hours of light and 12 hours of darkness. Be sure to give the plants at least three weeks in the vegetative stage before changing the light cycle, as this will allow them to grow strong and healthy.

How Many Hours of Light do Feminized Seeds Need?

Depending on the stage of growth, feminized seeds will need 12-18 hours of light per day. For the vegetative stage, 12 hours of light is sufficient, but during the flowering stage, they will need 14-18 hours of light per day. Therefore, it uses grow lights or by placing the plants outdoors in an area that receives full sun for most of the day.

What is the Best Light Spectrum for Feminized Seeds?

The best light spectrum for feminized seeds is a mix of cool white and warm white LEDs. It will provide the plants with the full range of wavelengths they need for photosynthesis while also giving them the red and blue light wavelengths needed for healthy growth.

What Light Cycle Should Seedlings Be On?

For the first two weeks after germination, seedlings should be under 24 hours of light. It will help them to grow strong and healthy before being transitioned to a 12-hour light cycle. After 3-4 weeks on a 12-hour light cycle, one can induce them to flower by changing the light cycle to 12 hours of light and 12 hours of darkness.

Feminized Seeds Wrap Up

If you want to feminize your cannabis seeds, it is important to understand the light cycle and how it impacts flowering. By using a 12-12 light schedule, you can encourage your plants to produce female buds. Remember, not all strains of cannabis will respond the same way to this type of light cycle, so be sure to do some research before you get started.

When can seedlings be put under lights or in the sun?

Not sure whether to grow your cannabis seeds in the sun or under lights? This article explains how much light you need, how to prevent your seedlings from falling over, and when to plant them outside.

“When can cannabis seedlings be put under lights or in the sun?” is a common and sensible question that is often asked by novice cannabis enthusiasts after germinating seeds indoors under lights.

For those who are growing indoors, cannabis seedlings may be put under lights as soon as they emerge from the soil or growing medium.

How much light for cannabis seedlings?

When using HID lighting (usually a metal halide lamp), young seedlings should be kept at least 50cm from the bulb.

With compact fluorescent lamps (usually 100w or more), a distance of around 15cm should be maintained between the top of the young seedlings and the bulb.

If using normal fluorescent tubes (18-36w), seedlings can be kept within a few centimetres of the light source.

Cannabis seedlings growing under lights should always be given a gentle breeze from an oscillating fan (a small household fan on the lowest setting is fine), as constant gentle movement will strengthen their stems significantly.

Are your cannabis seedlings falling over?

If cannabis seedlings grow tall and then fall over, this is almost always a result of growing in an environment with static air.

Seedlings intended for outdoor growing should be kept by a sunny window for the first week or two after emerging from the soil.

When they have grown their second or third set of serrated leaves (after the the round cotyledons that initially emerge from the seed) seedlings are usually hardy enough to flourish in direct sunlight.

When to plant your cannabis seedlings outside?

If outdoor temperatures are suitable, seedlings may be acclimatised to direct sunlight by giving them progressively longer daily exposure to outdoor conditions.

Starting with about three hours outside, at the sunniest time of day, seedlings can be given an extra hour of outside exposure each day, so that within about two weeks they can be left outdoors permanently.

Laws and regulations regarding cannabis cultivation differ from country to country. Sensi Seeds therefore strongly advises you to check your local laws and regulations. Do not act in conflict with the law.

Understanding the Cannabis Light Cycle to Improve Yield

The most important part of growing cannabis is getting a favorable yield that brings smiles and profit when it’s time to harvest. Growing cannabis, however, can sometimes be challenging for beginners . The success of your marijuana grow frequently depends on one crucial factor: lighting.

Lighting is crucial when you are growing your cannabis, whether indoor or outdoor. The light cycle you use for flowering cannabis directly correlates to a crop’s quality and overall yield. Yes, you need light to grow your cannabis, and here is what you need to know about the cannabis plant light cycle.

There are two stages of cannabis growth where it is important to strategically monitor your light cycles. These are:

  1. The vegetative stage
  2. The flowering stage

The Vegetative Stage Light Cycle

This is the stage where your plants are growing. This stage is very vital for the success and health of your cannabis plant. At this stage, the stems and leaves of the marijuana plants start growing larger and taller. However, also at this stage, the cannabis plant doesn’t produce any buds and you will have to control the shape and size of your plant. That is where the cannabis light cycle comes in: the light for your plants can be manipulated at this stage to yield better growth. The more lighting your cannabis plant receives, the better their growth and future yield.

When marijuana plants are in the vegetative stage, keep them under a minimum of 18 hours of growing light (also known as 18/6). But if you are one of those growers that would like their plant to grow as big as possible, then you may keep them under 24 hour (24/0) indoor light.

Cannabis plants don’t start developing flowers until they start receiving 12 hours of continuous darkness. Otherwise, they will continue to remain in the vegetative stage. As long as your cannabis plants are getting about 13 hours of light (or more) every day, you can keep your plants in this stage forever.

Indoor Vegetative Stage

Note that while in the vegetative stage, light is not the only means of growing large cannabis plants. If you are growing your plants indoors, you will need a well maintained grow room with a high ceiling.

Also, it’s important to note that certain cannabis strains (like Northern Lights and Jack Herer, for example) grow higher yielding crops even without such manipulations.

Outdoor Vegetative Stage

Typically, most growers would start their cannabis plants indoors under lights before moving them outside to grow under the sun. Most growers would usually start either cutting clones or starting seeds during March or April, and would keep them under 18 to 24 hours of constant light before moving them outside in the early period of May or June.

So, if you have plans to grow your cannabis outside, it can be helpful to first keep them inside until all forms of danger like frost, for example, have passed. A sudden drop in temperature or a late spring snowfall can kill your cannabis crop outright.

But, once such risks are over, your plants will be in vegetative stage outdoor from the late period of spring down to late summer.

The Flowering Stage Light Cycle

For your plants to move from their vegetative stage to the flowering stage, they will need to be exposed to 12 or more hours of darkness each day to start flowering.

Flowering Indoor Cannabis

Most growers that grow their plants indoors begins from the point of 12 hours of darkness immediately the plants have reached the desired size and shape during their vegetative stage. Usually, most growers prefer an indoor vegetative period of 4-8 weeks under a 24/0 or 18/6 light period.

To grow cannabis successfully indoor, you need to mimic the natural growth pattern. When you grow your cannabis outdoor, they start to develop buds (flowers) as the days gets shorter, and they receive a minimum of 12 hours of complete darkness. To do this, just switch your light usage from 18 to 24 hours of good sunlight daily down to 12 hours of light and also of 12 hours of darkness for the cannabis life cycle.

Flowering Outdoor Cannabis

If you have plans to grow your plants outdoors, allow nature to take its course. During this time period, the cannabis plants will start to produce flowers naturally on their own, which usually happens after the 21st of June, as the days start getting shorter.

Of course, the plants will not stop growing or developing flowers at this particular instance. On average, the plants start doubling up in height and shape after they begin the flowering stage — this is true for both indoor and outdoor plants. However, make sure your cannabis plants are NOT exposed to light during the 12 hours they are supposed to be in darkness. Take care: floodlights and even street lights can seriously disrupt the flowering period.

Scheduling Your Light Cycles for Maximum Yield

Are you planning to grow your cannabis indoor or outdoor? It is crucial you understand light cycles for cannabis seedlings so you can define the best light schedule for your crop. If you can follow up with a beautiful lighting plan, you will get maximum yield during harvest.

If you are growing your cannabis plant indoors and you do not have any issue with room height or space, then you should allow your plant to remain under 24/0 or 18/6 light schedule during the vegetative stage. This should last for 60 days, which is the best time to grow more flowers.

On the other hand, if you plan to grow outdoor, your light cycle for flowering cannabis should also be scheduled for 18/6 or 24/0, but you will want to first keep them inside until all unfavorable conditions like freezing temperatures and frost have passed. After that, you can safely bring them out and allow them to grow and flourish naturally under the open atmosphere, relying on the sun’s natural light cycle.

From the moment you have successfully crossed the vegetative stage of your cannabis plants, from 3 to 6 months, get ready to reap a bountiful harvest from your seedling efforts.

Final Thought

There are a whole lot of benefits to growing your own cannabis. However, you can only get the best harvest and therefore the most benefit from homegrown cannabis by knowing the various light cycles involved during the planting and growing of your crop.

You will have to do some experimenting to get truly familiar with the cannabis light cycles we have discussed. If you are cannabis cultivation newbie, however, you can stick to the tips above and rest assured that you will find success along the way.
