Do you want to go from seed to bud quicker and cheaper? A faster, space saving and economical way to grow is the no veg, seed to flower, 12-12 light cycle method.
Force flowering marijuana from seed can provide excellent quality, resinous flowers, all the while saving space, time, and money. For those with space constraints, it is a win-win!
WHAT IS 12-12?
Always be sure to re-sterilize your grow space after each crop.
12-12 simply refers to the hours of light and darkness a cannabis plant is exposed to – 12 of each. Normally, a cannabis plant is exposed to an 18-6 light cycle. This tells the cannabis plant conditions are good for growth, and it focuses on building up size and foliage. When light cycle is changed to 12-12 (either naturally or through human intervention), it tells the cannabis the seasons are changing, and it is time to flower. By forcing a 12-12 light period from the start, the cannabis plant goes directly into flowering, in a bid to reproduce. You are essentially tricking the plant into thinking the growing season is coming to an end, so it needs to produce flowers ASAP.
Everything to which you would pay attention in a normal grow remains unchanged and are still just as important. pH and water quality, nutrient mixing, pest control, grow medium conditions, EC and ppm all still play their major roles in the dankness and weight of your finished product.
Like most of its relatives, this strain is usually grown indoors under lights. She also does very well outdoors, due to her mainly Indica genetics.

That’s pretty much it in terms of the negative side of the 12-12 from seed method, although some growers feel that it has a slight impact on the quality of the bud. Just give it a chance and find out if it works for you. Even if you decide it’s not for you after trying, the experience will help you learn more as a grower.

Three of the four main Jack phenotypes have a marked Sativa tendency. In contrast, the fourth has an Indica-like growth pattern – fast flowering and relatively compact, dense structure, abundant and rounded “buds” suitable for commercial cultivation. These characteristics make Jack Herer the ideal choice for the 12-12 from seed method.
Therefore, they usually use an 18-6 light cycle to keep their plants in a vegetative phase for around two to four weeks and then switch to a 12 -2 cycle for the flowering stage, so the plants receive equal amounts of light and darkness.
Jack’s Sativa phenotypes can also give a good yield per yard or per plant when cultivated with care. The trait that all Jack Herer phenotypes have in common is their dazzling double-acting potency – a stratospheric cerebral “high” reinforced by an impressive stone of seismic power. Smokers should be prepared to experience something like an earthquake – which can be a very enjoyable feeling when their head is firmly planted in the clouds.
Northern Lights is one of the last few pure Indica’s. This makes her grow robust and compact, terms that also apply to her buds. During flowering, this plant gives off relatively little odor, making it very suitable for the discreet cannabis grower!
Giving a 12-12 shedule when a cannabis plant is younger than that will not work to make the cannabis start flowering – a cannabis plant will only grow vegetatively for the first few weeks of life, and giving them less light will only cause them to grow more slowly.
Many Growers Who Want To Force Cannabis Plants to Flower at a Young Age May Be Interested in Auto-Flowering Strains – No Need for 12-12 and Often Much Better Yields!
This seedling took 4 months from seed to harvest, and yielded only 1/2 of an ounce. I think it looks kind of cool, but 1/2 ounces is not a good harvest after waiting so long. You can double or triple your total yields per plant by tweaking the light schedule a little during the first few weeks
The problem is that seedlings can’t start flowering until they’re 3-4 weeks old no matter what light schedule you give them, so there’s no point in starting right at 12/12 when they’re under 3 weeks old. When you give the plant 3-4 weeks of 18/6, THEN switch to 12/12, you will get far better results because the plant will get more light in those crucial first few weeks and end up much bigger by the time it’s ready to make the switch.
Some people say that cannabis that is forced to flower too early will not make any buds, but that’s not true. The plant pictured here produced 0.75 ounces of bud after drying. So while 12-12 from seed may not be optimal, it does work.
I have grown a few plants from seed to harvest just in a solo cup container. I was able to do this by flowering a plant from a young age – giving the plant 12-12 lighting when it was only 3 weeks old (pictured here).
There are powerful cannabis growth control techniques that will also allow you to grow high-producing plants, while keeping them short.
Keeping plants in tiny containers may be important when growing in a very space-limited grow space, such as growing in a space bucket for stealth reasons.
Some growers are attracted to the idea of 12-12 from seed, because it means that harvest will come sooner. How long does it take to grow a plant from seed to harvest?
