The following article describes the complete growing cycle for marijuana as well as the time required for each stage. Keep in mind, this articles is describing the type of weed one smokes, but you get the idea. Medicinal Marijuana is typically grown to a controlled strength or potency, and thus requires a little more time.
How Long Does It Take To Grow Cannabis?
Generally, it takes about 3-4 months to grow the average cannabis plant – but with the right tools and strategy, you can grow the weed plant you want in as little as 8 weeks. Let’s take a look at the breakdown of growing cannabis indoors and the time needed for each step.
Cannabis Growing Timeline
The timeline below lays out a seven-phase process of a typical grow schedule.
Step 1 : Getting your equipment = 1 day to 2 weeks
If you know what you are looking for then this could happen quickly. We will help you with this later on as we set up the grow-rooms and do some grows with different styles and grow mediums.
Step 2 : Getting your clones or seeds = 1 day to 4 weeks
Getting clones (cuttings from healthy mother plants) is easy to do in areas that allow cannabis cultivation. But in states or countries where it is illegal to grow, obtaining healthy clones can be a challenge. Seeds, on the other hand, can be ordered on the internet and generally take 2 to 4 weeks before they arrive by mail.
Step 3 : Germinate The Seeds = 12 hours to 8 days
If starting with clones this can be skipped. The average time to germinate is 2 or 3 days.
Step 4 : Seedling Phase = 1 week to 4 weeks
Once again, can be avoided if using clones and not seeds.
Step 5 : Vegetative Phase = 2 weeks to 6 Months!
Yes, that is correct. This stage in the plants life has a huge fluctuation in how long it needs to take. You, as the grower, hold all the power and get to choose how long this phase is. Once you change the light cycle that the plant receives to 12 hours of light, and 12 hours of darkness per day, the plants will switch to the next phase, which is flowering.
If you want to, you can switch the lights to 12/12 right away and force your plants to flower! The sooner you change to 12/12, the faster your plants will flower, and the sooner you can move on to the next crop. But, keep in mind, the less amount of time you keep your plants in the vegetative phase, meaning getting at least 18 hours of light per day, the smaller your plants will be, and the less marijuana you will have to use. If you are concerned with how big your plants will grow, maybe because you only have a small space to grow in, you can grow cannabis that only grows a few inches tall, and you could even grow it the entire time in a little plastic cup if you wanted to!
Keep in mind that buds do not form for at least 2 to 3 weeks in the vegetative phase when beginning with seeds. Most growers allow their plants to stay in the vegetative stage from a few weeks to a few months so they get big enough and will end up with a sizable harvest. Bigger plants produce more buds! But, many growers choose instead to grow small plants and to harvest more often with smaller yields each time. We recommend at least 3 weeks or more in the vegetative stage with at least 18+ hours of light each day for optimal yields. Even 24 hours of light per day is sometimes better, with certain strains.
The more light, the more buds!
Keep in mind that cannabis plants usually double in size from vegetative phase to when they are done flowering. This means it is sometimes best to change to 12 hours of light and 12 hours of darkness once the plants are one-half the size that you feel your grow room has adequate space for.
Step 6 : Flowering Phase = 6 weeks to 3 months
In nature, cannabis plants start to flower in the fall months, when they are receiving less light. The decrease in light signifies to the plants they are nearing the end of their life cycle and its time to begin flowering.
Indoors, this action is done by changing the amount of light the plants receive to a schedule of 12 hours of light, and 12 hours of uninterrupted darkness. The plants will require less nitrogen during this time than they have had in the previous vegetative phase. The needs for phosphorus and potassium will increase, so you will now use a nutrient with a higher P&K ratio. If at this time you still are not sure if the plants have revealed the sex or not, they will in about 7 to 10 days after being in the 12/12 light cycle. Look for two white hairs coming out of the nodes on the plants. These hairs are the pistils that are found on the females.
Most cannabis plants flower for around 8-14 weeks. Depending on the strain, some may flower a lot longer than others. Pure indica strains usually finish around 8 weeks of flowering, while pure sativa strains usually finish around 12-14 weeks. Some sativa strains have been known to flower for 16 weeks or longer. For this reason, indica strains are most commonly the kind that are grown indoor.
Most growers like to grow, harvest, sell, and get back at it as quickly as possible to turn a faster profit. If you are not in it for the profit, sativa strains can be fun to grow. You could let them grow real big and tall if you have the ceiling space or outdoor area for them. Make sure to research the strain your growing so you have a general idea of the flowering time.
Step 7 : Harvesting = 1 to 3 days
