Most growers choose to let plants vegetate for longer because giving them more time to grow results in bigger plants, which tend to produce bigger yields as long as you have enough light to cover all the bud sites. That being said, you can still produce quite a bit of bud with a lot of small plants growing at once as long as you fill up your grow space. Flowering Stage (5 weeks – 16+ weeks) – This is when plants start making buds. The length of the flowering stage depends heavily on the strain/genetics, with an average of about 8-12 weeks for most strains.
Some strains are bred to have very short flowering stages (for example, most auto-flowering strains will naturally start flowering at around 3 weeks old and some are ready to harvest just 5 weeks later, for a total of only 8 weeks from seed!). Other strains can take months in the flowering stage before they’re ready to harvest. Typically, longer-flowering strains produce higher yields than short-flowering ones because the buds are exposed to more light-hours and have more time to fatten up, but that’s not always the case. Post-Harvest (This is when the smell/taste/look you love shows up) (2-4+ weeks) – After buds are harvested, they still need to be dried for about a week (sometimes a bit less or more), then placed in glass jars to “cure” for at least 2 weeks. This post-harvest processing dramatically improves the taste, smell and the perceived potency of the buds. It also reduces the chance of buds causing headaches or unpleasant “speedy” effects. It will account for nearly 50% of your final bud quality! If you choose the right strain, you could be smoking your own buds as soon as 3 months from germination! Here’s the breakdown… Get equipment: 0 days – 2 weeks This includes purchasing your equipment and/or waiting for it to show up in the mail.
Once you have your marijuana growing supplies, you’ll need to setup your growing area and equipment. 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). Check out examples of new grower shopping lists to learn exactly which supplies you’ll need. Get seeds or clones: 0-4 weeks: If you have instant access (like knowing a grower, or ordering seeds from a seed bank in your country), this should take only a little time. If you order from a seed bank overseas (especially US residents), expect a wait of about 1-4 weeks to get seeds. Time Needed to Grow Weed, From Seedling to Harvest. Here’s the breakdown… Seedling Stage Germinate your seeds: 1 – 7 days Seedlings can sprout in as little as a day, but by 3-5 days they should be good to go. If you have access to clones, you can skip this wait. Learn my fail-proof method to germinate your seeds in soil/coco or hydro. Vegetative Stage Vegetative Stage: 3 weeks – 2+ months. The length of this stage is a matter of personal preference. Most cannabis plants need at least 3 weeks in the vegetative stage before they will start making flowers, but after that you get to choose how long your plant spends in this stage (unless using an auto-flowering strain), because you’re the one to ‘flip the switch’ and get your plant to enter the next life stage: flowering. When you start with a seed, even with an auto-flowering plant, you will always have at least 2-3 weeks of vegetative growth before any buds start forming no matter what you do. Growers generally allow their plants to stay in the vegetative stage from a few weeks to a few months. The size your plant achieves in the vegetative stage has a very large effect on your final yields since bigger plants produce more bud sites than smaller plants. However, you need enough light to cover all the bud sites or they will never develop properly. These vegetating plants are about 4 weeks old from germination. To give you an idea as to what your FINAL marijuana plant may look like depending on how long it spends in the vegetative stage… This plant didn’t spend any time in the Vegetative Stage. It was given 12-12 lighting almost immediately after sprouting. It’s so small that it spent its whole life in a solo cup, and its only light came from CFLs. I weighed down the bottom of the cup so it didn’t fall over. 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. This marijuana plant spent about 6 weeks in the vegetative stage before being changed over to flowering and yielded just over 6 ounces at harvest. View the complete grow journal with instructions on how to grow your plant so it looks just like this at harvest! These cannabis plants were vegetated for about 8 weeks before being flipped to the flowering stage.
Although they were grown in the exact same conditions from seed to harvest, their final heights are remarkably different because their strains had vastly different genetics. The smaller plant produced 6.6 ounces, while the big plant produced 9.3 ounces. These cannabis plants were vegetated for about 9 weeks before being flipped, in the exact same setup as above, and produced over 10 ounces each. Besides an extra week of veg, the biggest difference between this grow and the one above was simply the strains. This human-sized plant (one of my very first plants) spent a little more than 3 months in the vegetative stage before I realized I needed to turn it over to the flowering stage. It then spent another 12 weeks in the flowering stage before it was ready to harvest because it was a long-flowering strain. It got way too tall for its space (taller than me!) and started falling over.
However, despite the huge size and more than 5 months of growth, it only ended up yielding about 6 ounces. Though there was a lot of buds, the lack of strong light made them airy, without a lot of weight. 🙂 Some people put their seedlings or clones right into the flowering stage if they want to harvest quickly though this makes for extremely small plants.
