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.
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.

The 12/12 Method: The New Craze in The Canna-Cultivation World
Cannabis growers all over the world are constantly seeking new methods and ways of cultivation; this is especially true for indoor growers because of space restriction. They believe that having limited space should not hinder their plant growth and yield.
The introduction of a new method known as the 12-12 from seed method has gained wide acceptance among the indoor cannabis growers. The photoperiod cannabis strains usually flower based on their light cycle, this is usually recreated by the indoor cannabis growers to keep them in their vegetative phases and enable them flower. The 12-12 in the name refers to the 12 hours each of light and darkness the plant is exposed to immediately after germination.
The normal method which has been used for a long time is to use an 18/6 cycle in the vegetative phase which takes about 2-4 weeks before switching to a 12/12 light cycle for the flowering phase. However, the 12/12 technique skips the traditional vegetative phase entirely to force them into flowering immediately by making use of the 12/12 light cycle. Rather than the plant focusing on developing its size and leaves, it is tricked into flowering immediately in a bid to reproduce.
It is especially appealing for growers who have serious space problems as the plants grow much smaller and manageable than the regular plant which went through the vegetative phase. They are a lot less bushy and have fewer branches and can produce an average of 5 harvests per year in some cases thus making it more attractive for those growers who don’t have a lot of time. The 12/12 photoperiod growing method is an economical and space-saving way of growing your cannabis plant. It takes an average of only 7-9 weeks straight from seed to harvest which is quite faster when compared to the regular cannabis growth.
The 12/12 method of cultivation does not need any special care except changing the duration of its light cycles. The plants are still to be treated as always, receiving care and love from the grower as always in terms of growing medium conditions, nutrients, pest and disease control among others. This should be monitored most especially while the plants are young just like it would be during a normal bud cycle.
They are easier to maintain as there are far fewer leaves to handle while trimming thus freeing up your valuable time.
It allows for good light penetration to the plants and an easier maintenance routine as the plants are accessible and can be moved around.
They are capable of growing in a tiny area
it is money-saving as there is a reduction in demand for resources like water, nutrients, and electricity across the board and reduces wear and tear on the moving components.
It allows for efficient space-saving as the plants have fewer side branches and do not spread excessively like those grown using the regular method.
The 12/12 cannabis growing method has both its opponents and proponents as some believe that plants that are produced using this method give growers lower yields as a result of being unable to produce budding sites and have lower concentrations of THC. On the other hand, some growers say it is so effective that it produces very good and bountiful cannabis harvests with some of them claiming to get as much as one gram of weed per every watt of light used. Although this might not be the case, the 12/12 cannabis growing method has its merits and will continue to be adopted by many cannabis growers over time.
Resterilizing the grow area after every crop is important to keep it clean and sanitized.
Keep mold and mildew at bay by regularly checking your plants especially those in areas with less light.
The right cannabis plant variety is important for this cultivation method as some varieties like Indica are known to not work well with this method. Hybrids and the Sativa varieties are known to work well as their growth and root development make them ideal candidates for this method.
Powerful lighting and air circulation system ensures that your plants get strong lighting and enough air to develop well.
Your plants will notice any abrupt changes in lighting so use the right one such as the HPS lamps from the beginning and a poor lighting system will result in stunted growth.
It is important to keep in mind that a cannabis plant that has undergone the 12/12 method of cultivation will look different from your regular plants. This is because the photosensitive hormones on your plant make the largest cola its highest point and the plant will likely have a few short branches with only a major bud. However, this is where the difference ends as there is no means of identifying cannabis grown through this method through flavor and effect.
