Vegetative plants appreciate healthy soil with nutrients. Feed them with a higher level of nitrogen at this stage.
Outdoors, flowering occurs naturally when the plant receives less light each day as summer turns into fall. Indoor growers can trigger the flowering cycle by reducing the amount of light marijuana plants receive from 16 to 12 hours a day.
We can’t stress enough that the timeframes in the above graphic are ranges of time for the Northern Hemisphere. You’ll need to adjust them based on your specific region and local weather and climate.
The weather will start to turn and the sun will begin descending in the sky as your plants fatten up with sweet, sticky buds. It might be tempting, but wait until around the Fall Equinox to start harvesting.
Buds typically grow the most toward the end of the flowering life cycle. You probably won’t notice much budding out at the beginning of the flowering stage, and it will slow down toward the end of the cycle, when buds become fully formed.
If you’re growing indoors, you can force a weed plant to flower after only a few weeks when it’s small, or after several weeks when it’s big. If you’re growing outdoors, you’re at the whim of the seasons and will have to wait until the sun starts to go down in fall for it to flower and then to harvest.
Once your seed has germinated, or sprouted, it’s ready to be placed in a growing medium, like soil. The tap root will drive down while the stem of the seedling will grow upward.
Once you confirm you’ve got a ripe marijuana crop on your hands it’s time to break out the trimming scissors and get harvesting. After two weeks slow drying in paper bags or hung up, at room temp and approximately 50% RH, you’ve got a stash.
Now that you know when to start harvesting your buds, it’s time to learn how to trim them.
Harvesting is the most rewarding part of the cultivation process for many growers. Watching your plants grow over several months is mesmerising, but finally harvesting the fruits of your labour truly is the peak of the experience. The flowering phase of the grow cycle typically lasts between 7–11 weeks, after which it’s time to strip your plants down of their buds. However, you don’t want to do this too early and prevent your flowers from fully maturing. Likewise, you don’t want to wait too long. Timing harvest is a crucial step, and there are multiple signs you should look out for to know when the time is right.
STAGE 3: VEGETATIVE PHASE — 2–8+ WEEKS
It’s always best to evaluate if a cannabis plant is ready to harvest by taking a closer look at those resin dripping buds. Using an inexpensive scope to zoom in on those resin heads to make sure they are milky and amber rather than clear removes all the guess work.
Royal Queen Seeds produces some of europe’s best cannabis seeds, ensuring hobby growers everywhere have access to the finest marijuana strains around.
Growing cannabis comes with a lot of uncertainties. That said, cannabis cultivation itself can be broken down into five distinct stages, regardless of which seeds you’ve selected.
Of course Autoflowering strains don’t follow the rules due to their Ruderalis genetics, so they will begin to bloom in about a month post-germination. Auto’s prefer to stay in 18+ hours of light for flowering and will be more productive on a light-dark cycle that would inhibit photoperiod strains from blooming at all.
Get equipment: 0 days – 2 weeks
This includes purchasing your equipment and/or waiting for it to show up in the mail. This goes much quicker if you buy everything locally, for example at a hydroponics shop. Once you have your marijuana growing supplies, you’ll need to setup your growing area and equipment. A standard setup should take an afternoon at most. Depending on how you purchase your equipment and how quickly you setup, you could be ready the same day or in two weeks (after factoring in shipping time).
This article will give you the total time breakdown, so you can plan out the details of your grow in order to achieve the harvest times you desire:
Before You Start Growing Weed
These auto-flowering plants spent about 3 weeks in the vegetative stage before they automatically started flowering, and were ready to harvest just 5 weeks later. They were about a foot tall at harvest and yielded approximately 2 ounces each. Read the step-by-step tutorial to grow plants exactly like this.
Total preparation time needed: Up to a few weeks
In general, most strains (besides auto-flowering strains) are in the medium range as far as how long they take to flower.
