12/12 From Seed: Doing It Right

Some of the most sacred rules of cannabis growing tell us that in order to grow and successfully harvest photoperiod strains, you need to let the plants grow and gain mass during their vegetative period. Now, what if we told you that some rules are meant to be broken? Thanks to some daring enthusiasts who weren’t afraid to take a risk, we now know that even photoperiod strains can be grown 12/12 from seed – in other words, put straight into the flowering phase the day they germinate. Should you try it? Is it worth it? What about the yields from 12/12 from seed? In the true spirit of experimentation, we’re going to answer these questions and many more in this Herbies article, so read on!

12/12 From Seed: The Method Explained

We know, it’s exciting to find out that there’s a way to stop all the questions about exactly how and when to transition plants grown from photoperiod seeds into the flowering stage. With the 12/12 light cycle from seed, you give your weed plant 12 hours of light and 12 hours of darkness every day without exception, from the day the seed pops until the day you snip off the buds. That’s one problem less – but at what cost does this convenience come?

The Role Of Veg And Flower

Of course, if cannabis plants naturally go through both vegetative and flowering stages, they need these periods for certain reasons. During the vegetative stage, which lasts while photoperiod strains receive more than 12 hours of light per day, cannabis plants actively grow, become thicker and taller, and often reach their maximum possible height, signaling that they’re mature enough to procreate and make buds.

When the schedule is switched to 12 hours of light per day or less, the plant can still stretch a little, especially if it’s a Sativa, but from that moment on, it will direct all its accumulated power to making those sticky and smelly buds we grow cannabis for in the first place.

Apparently, however, you can skip the vegetative phase entirely and set your cannabis to 12/12 from seed. So, what are the consequences of skipping the veg?

Cannabis Light Schedule

What Happens When You Skip The Veg?

If you decide to skip the veg and carry out the 12/12 from seed grow at home, you need to understand that by switching cannabis plants to flowering straight after germination, you deprive them of the time and light energy they would normally use to grow, mature, and prepare themselves for developing buds. With the 12/12 light cycle from seed, your photoperiod cannabis plant will only reach the minimal mass and height that it can use to start procreating. As the result, plants grown on 12/12 from seed become extremely compact, and thus yield less than their counterparts that went through the standard vegetative period.

However, such a bold move proves that there’s still much to learn about cannabis growing. While we wouldn’t have dared to even think of skipping the veg before, we now know that cannabis won’t die, and indeed will still yield buds, if we use 12/12 from the day the seed pops. If you’re looking for proof, there’s lots of it in the special 12/12 from seed Growdiaries section, where growers share their experiences with skipping the vegetative period.

Now let’s move on to the pros and cons of this growing method. Give it a read-through and decide whether 12/12 from seed is worth it for you.

Guide to: 12-12 From Seed Technique

With regular and feminized seeds, you need to determine when to end the vegetative phase and make the plants flower. Usually, it can take several weeks. However, you can force your plants to flower a lot earlier than when they are under regular conditions.

By managing how much light cannabis receives, you can begin harvesting as soon as possible. Some people have time and space constraints. Growing 12-12 from seed is beneficial if you experience both of those challenges.

What Is Growing 12-12 From Seed?

Growing 12-12 from seed means that you would give your seedling 12 hours of light and 12 hours of darkness soon after germination. Usually, cannabis receives an 18/6 cycle during the early stages of life. Switching to a 12-12 schedule initiates the flowering stage.

With equal amounts of light and dark, your young plants would begin flowering right from the start. Some growers grow 12-12 from seed since it is perfect for solo cup growing. The plant’s roots do not need much room to grow, since the vegetative period will be short.

So, a solo cup or another small container can work well. However, you may need to water cannabis a bit more frequently.

Advantages

One reason you might want to try using a 12-12 light cycle after germination is the shorter cultivation time. Cannabis typically takes 3-4 months to reach harvest. You can enjoy some nice buds sooner than expected.

Trimming becomes less of a hassle as well. You do not need to manage as many sugar leaves compared to when you grow marijuana normally. You can save money on water, nutrients, and energy as well.

Another advantage of growing weed under 12-12 lighting is the space you can save. The plants can grow in smaller containers, and the branches do not extend too far. Not to mention, cannabis plants are easier to move. You can turn them around for the light to reach all the leaves.

Disadvantages

Some growers do not grow 12-12 from seed due to a few of the disadvantages. One of the main drawbacks is the reduced size of the plants. The shorter vegetative phase means the plant has less time to mature to its full mass. Still, you can get desirable yields.

You would not be able to do a lot of the training techniques as well. Most of them occur during the vegetative stage, so you would not have enough time to do something like monster cropping. One of your options would be low-stress training.

Expected Yield When Growing 12-12 From Seed

If you are intrigued by growing marijuana with 12-12 lighting, you might wonder how much you can harvest. The yield weight is usually not that hefty, but the lights, strain, and pot size can make a difference.

If you grow a seed in something like a solo cup, the average amount is 3.5 grams. You can get around 14 grams from a plant with a slightly larger pot. Some cannabis growers prefer to use containers of up to a gallon. They can get up to 28 grams for each plant.

However, you can get much more from your crops if you grow them with the SoG method.

How to Grow Cannabis 12-12 From Seed

Growing a cannabis seed with a 12-12 light cycle only has a few steps. They are simple to do, and you do not need much when it comes to equipment. If you decide to use this method to grow weed, what you need to do is:

1. Germinate Seeds

For germination, the seeds need some dampness and a warm environment. There are multiple ways you can go about germinating cannabis seeds. Some growers buy starter cubes since they are convenient.

They contain some micronutrients to encourage the roots to grow. Add some water and wait a few days for the germination process to complete. Instead of a starter cube, you could use a non-porous paper towel instead.

Take a paper towel and make it damp. Then, you would fold it over the seeds and wait around 1-4 days. It is helpful to have a spray bottle around since the paper towel can dry out. You can check periodically to see if the taproot emerged.

Once you see roots, carefully remove the seeds and move on to the next step. For tougher seeds, some growers leave them in a glass of water overnight. You could soak your seeds in water and place any stubborn ones in a paper towel afterward to get them to sprout as well.

2. Plant Seeds

Now, you need to plant your germinated weed seeds. You will need to gather tweezers, growing medium, and a pencil. You should also have a small container or lightproof pot. Once you have everything you need, fill the container with soil or another type of growing medium.

The soil should reach just below the top of the container. Many growers fill it up to about 1 centimeter from the top. Then, you would make a small dimple in the dirt with a pencil. The hole should be a couple of centimeters deep.

Use the tweezers to pick up the seed and carefully place it in the dimple. When it is in the hole, you can cover it with a layer of soil. It is necessary to avoid pressing down firmly on the growing medium. The sprouting seedling could have a harder time emerging from the topsoil.

Spray some water to dampen the soil, but you should not add any nutrients at this time.

3. Switch Lights to 12-12

After a couple of weeks, you will see the seedling get bigger. You then can switch the lighting schedule to be 12-12 around the 3-week mark. The plant should start flowering as early as possible. Once it does, you can expect most strains to take roughly 12 weeks to be ready to harvest.

Many seedlings do not begin to flower immediately under a 12-12 light cycle. They usually do not start producing buds until they are 3-4 weeks old. It will not be long until you see some desirable results.

Tips for the Best Results on Growing 12-12 From Seed

Stay On Top of Your Plant’s Need

Even though the life cycle is shorter than usual, you should still pay attention to the plant’s needs. You have to monitor airflow, soil pH levels, and water quality like you would during regular marijuana growing.

Pests and mold can still be a problem. The plants can experience stress, which may mean stunted growth. Not to mention, the number of nutrients a plant receives can change as it gets bigger. You do not want the young seedling to suffer from any deficiencies or burns.

Some growers are concerned that growing 12-12 from seeds reduces yield sizes, but all these factors can ensure a maximized harvest.

Use the SoG Method

If you want to boost your yield size, you can use something called Sea of Green (SoG). The SoG method involves growing many small plants together instead of larger ones. You would place one or two plants down for every square foot.

The SoG setup does not require much effort, and you can grow various strains. However, you would need at least four plants for this method.

The technique works well with growing 12-12 from seed. You would change the light cycle around the third or fourth week, which increases how much you harvest in the end.

Do Not Use Autoflowers

Growing seeds under a 12-12 schedule would not be effective for autoflower plants. You would not be able to get the results you want. The reason is that autoflowers do not need a light cycle to transition to the flowering phase.

As a result, it would not matter if you use a 12-12 or 18-6 schedule. The autoflower plants have their own timeline, and you have less control of their flowering pace. A few autoflower strains might reach harvest sooner than other seeds.

You can buy one that reaches its harvest time quickly if you need to finish growing cannabis sooner.

Final Thoughts on Growing 12-12 From Seed

Many growers like to grow 12-12 from seed, and others do not. You can try it out to see if the method is something you will enjoy. A part of marijuana cultivation is figuring out what works best for you.

Before you get started, you should buy some suitable strains for growing 12-12 from seed. The ones that react the best have a fair share of Indica genetics. The light change is not as effective for Sativa-dominant seeds.

One strain you can try is the Big Bud. The plant naturally has the potential for a large harvest, so you could get more when growing 12-12 from seed. The strain also is great for SoG if you choose to apply the method.

Grape Ape seeds can grow under almost any condition. They can have significant yield sizes and have high THC content. Alternatively, Pinkman Goo is a mixture of other great strains. While sticky, you can get some tasty buds.

Maximize Cannabis Yields With The 12/12 From Seed Method

If you’re looking to maximize your yields but you are limited on space, maybe it’s time to switch from your traditional cultivation techniques to the 12/12 From Seed method. Instead of cultivating from a clone, waiting through weeks of the vegetative stage, and growing plants that take up way too much room, the 12/12 from seed method produces high yields and maximizes your time, space and money.

Traditional indoor cultivation systems that run from clones maintain vegetative stage that lasts anywhere from 2-4 weeks, sometimes longer. The vegetative stage is maintained using an 18-24 hour light cycle, which prevents the cannabis plants from flowering. The 12/12 from seed method takes a different approach. By starting your garden from seed in stead of clone, you avoid potential problems like pests. By implementing a 12/12 light cycle from germination, you end up with a lean, dense plant, and by elimination of the veg stage, you will be able to harvest up to seven times a year. This makes it an ideal method of cultivation for anyone pressed for time and space.

STARTING WITH SEEDS

While growing cannabis from clones may seem like a quick and easy way to get started, they have their fair share of drawbacks. First off when you grow from a clone, you are limited whatever selection the local clone shop has, as you can’t ship clones through the post. Buying from a respected seed bank gives you selection and confidence that what you are buying is actually what you are getting. Next there is the risk of contamination. Grows are affected by pests and mildew not because they are inherit in the plant. They are brought in from the outside, often on clones purchased from contaminated sources. It’s just not worth taking the chance. Starting with quality seeds is a fundamental part of the 12/12 from seed method.

SKIP THE VEGETATIVE STAGE

The vegetative stage is the early stage of a cannabis plant’s life. It is during this time that the fledgling plants are fed a high nutrient regimen and are kept under either 18 or 24 hour light cycles to prevent flowering. This vegetative stage is a time when young plants grow into a rigid framework on which the heavy cannabis buds can sit. High levels of nitrogen are needed to reinforce cell walls, strengthening branches, and creating a lattice of limbs strong enough to support the weight of the incoming fruit. The 12/12 from seed system of cultivation does away with this entirely focusing the light’s energy into a single robust cola surrounding the center stalk.

Once your seeds start to germinate, going right to a 12/12 light cycle will forever change how your plants will grow. By removing the four week veg stage, you force the plant to grow a single dense cola around the central stalk, as the many branches of the plant have not had time to form. This causes flowering to being almost immediately. The central shaft will be surrounded by only a few smaller branches close to the base. The end result is 85-90 percent of the budding occurs in the single central cola.

ADVANTAGES OF 12/12 FROM SEED

High yields in small spaces is one of the primary benefits of the 12/12 from seed method of cultivation. By design, plants grown in the 12/12 method start flowering from day one. This causes flower growth to follow a very consistent pattern of short, tight, single cola plants, with few smaller branches. This allows the maximum amount of energy from your lighting system to be focused into the single central cola. This eliminates most lower branches and the space they take up along with them. This is ideal for those who don’t have much space to play with.

In eliminating the four weeks or more of vegetative time, you are able squeeze in more harvests per year. Using the 12/12 from seed method growers have been able to harvest as many as six or seven times each year. More plants per square foot plus more harvests per year equals an opportunity to truly maximize the amount of cannabis you can produce in even the smallest of spaces.

Switching to the 12/12 from seed method of cultivation produces the same dense, high THC rich nuggets of its traditional counterpart, however, is designed for those looking to maximize yields in tight spaces. By eliminating the vegetative stage, you are able to squeeze in a few extra harvests every year which will save you time and money in the long run.
