Unlike indoor growers, outdoor growers have to deal with the sun. This constant light source is a great thing for those looking to grow all season long. However, those seeking a fast harvest will need to find ways to reduce light exposure. As mentioned above, altering the light cycle is perhaps the most powerful way to speed up growth. When it comes to achieving a 12/12 light cycle outdoors to initiate flowering from the get-go, growers can cover their plants with a tarp for periods in the morning and evening to avoid excess light exposure.
Lastly, some growers who cultivate for personal use, whether for recreational or medicinal reasons, simply want a stash as fast as possible. Luckily for all these groups of growers, cannabis is a versatile species that can handle a broad range of environmental conditions. Environmental factors ultimately dictate how cannabis grows, and humans have mastered agriculture to the point that we can influence growing speed—at least to a degree.
The cannabis grow cycle features two distinct phases: the vegetative phase and the flowering phase. Manipulating the light cycle during both of these phases can result in a faster pace of growth. During the vegetative phase (when plants feature only fan leaves and have not started to bloom), indoor plants are usually vegged under 18 hours of light and 6 hours of darkness per day to provide the best conditions for photosynthesis and respiration to occur.
HOW TO CONTROL LIGHT EXPOSURE OUTDOORS
Vanilla Ice Autoflowering is a speedy lady that will explode from seed to harvest in as little as 55 days, without any of the above methods being implemented. She was created using the original Vanilla Ice, which was then infused with ruderalis. This indica-dominant specimen provides a giggly, happy, and relaxed body high with flavours of vanilla and sugar.
Regardless of whether you intend to speed up cannabis growth indoors or outdoors, genetics will play the most fundamental role. Some cannabis varieties have been selectively bred over generations to strengthen the trait of faster growth and flowering. Autoflowering strains in particular are famed for their speed, with most emerging from seed to harvest in a couple of months or so, without any intervention at all. Here are some of the fastest-growing autoflowering and photoperiod genetics you might want to consider for a lightning-fast harvest.
However, by providing 24 hours of light per day, you will force your plants to remain in an anabolic state (the process of converting smaller molecules into larger molecules). This is because they will be photosynthesising around the clock and constantly using light, CO₂, and water to create glucose as an energy source to fuel growth.
Lemon Kush is a fast-flowering photoperiod strain derived from Chemdawg, Lemon Thai, and Pakistani Kush. With a flowering time of approximately 55 days in normal conditions, this indica-dominant cultivar induces a stoning and meditative high shortly after being smoked. The terpene profile within her flowers features notes of spice and citrus.
Pruning your weed plant encourages them to focus their energy on producing buds rather than leaves. Extra stems and dying, yellow leaves should be removed to allow your plants to concentrate its efforts on growing buds.
It may sound obvious, but one of the easiest ways to reach harvest quickly is to choose seeds with short flowering times. Always buy seeds from reputable and established sellers who will display growing and flowering times on their websites. The aforementioned Northern Lights feature a two-month flowering phase, while others, such as Sour Diesel need to flower for more than 2,5 months. Strains with longer flowering times generally tend to perform better outdoors because they receive more sunshine. However, varieties with short flowering phases often produce cannabis of equally good quality.
Santa Maria, Gorilla Glue and White Widow x Northern Lights are among the many cannabis varieties that flower quickly. All of these strains have a flowering phase of six to eight weeks, shaving around a month off the entire process.
5. Start pruning
When your cannabis plants receive less than 13 or 14 hours of light a day, they will automatically start to flower. In the natural world, harvest occurs in the autumn, when the hours of daylight begin to decrease. Indoors you can mimic this and speed up the time of harvest.
You have to decide whether you want more weed or faster weed. It’s a question of weighing up the balance between your patience and the final result. If you are keen to learn how to make weed grow faster, we’ve compiled our favorite tried and tested tricks to help you reap the rewards of your labors in as little time as possible.
When growing cannabis indoors from ordinary seeds, the grower has to decide when to switch the plants from the vegetative phase to flowering. This is usually done by altering the lighting schedule. Reducing the total hours of daylight stimulates the plants to produce buds and will start the flower stage. This is usually about two to three months after sowing, depending on the variety.
A practical solution, if you are really impatient, is to cut short the vegetative phase. The yield will be less but much more than by entirely skipping the vegetative stage. Let your plants vegetate for a shorter period than that accepted in order to switch to flowering more quickly. The yield will certainly not be extraordinary, but always more than by making the plant flower from the sowing stage. It could take three more weeks, for example, in which case you will be able to harvest after about 14-15 weeks.
If you let the plants veg for longer, they grow larger and are able to grow a lot more buds. Of course, the size your plants can achieve is also constrained by the size of the pots they are in and the amount and strength of the grow lights.
The primary factor that influences how long it takes cannabis to grow is the strain. Choosing a fast-growing strain can shorten the time considerably.
The length of the bloom stage varies greatly. The primary factor that determines how long a plant takes to reach harvest time is the strain.
We begin before the grow even starts, with a stage we called “preparation”, because you will need a number of supplies to successfully grow cannabis. If you already have everything you need, you can obviously skip this stage entirely.
Growing from clones instead of seeds speeds up the process a bit, since the clones are already fairly well developed. You have to wait for them to root, but once they do, you have a huge head start over a seed.
If you’re starting from scratch, you’ll need to get all of the necessary supplies together. This can take a few weeks, depending on where you source your supplies.
But that is just an average. The time it takes for weed to grow varies greatly. As mentioned, it depends on a number of factors and can range from 8 weeks to well over half a year.
