Now that you have an idea of how long it will take to grow weed indoors, we can start to break down some of the specifics so you can get the most out of your operation.
A DETAILED TIMELINE ON CANNABIS GROWTH
You may already be set with some seeds and your grow room is ready to go. Great! In this case, there won’t be much prep time needed to start your grow. Otherwise, this period takes into consideration how long it will take to order and receive your seeds, as well as source any equipment such as potting containers and soil. This period will therefore vary depending on what you need, where you are buying from, the speed of your mail, etc. Expect the preparation time to take anywhere from 0–4 weeks if you still need some equipment before you can get started.
If you ask most growers how long it takes to grow weed, chances are you won’t get a straight answer. This is because the time it takes to grow weed can depend on many factors such as strain genetics, growing methods used, and certain environmental factors. All things considered, it could take anywhere from 8 weeks to 7 months until you can actually smoke your harvest. Below, we offer some guidelines on the timescales involved when growing weed, so you can plan your grow accordingly and reap the final rewards!
Your cannabis plant’s vegetative growing stage starts at about the time when it has outgrown its seedling pot and is ready to be transplanted into a larger pot.
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.
At this stage, the plant is vulnerable to disease and mold. Keep its environment clean and monitor excess moisture. Be sure to give it plenty of light.
How long does it take to grow a marijuana plant?
If you’re growing weed indoors, you can grow whenever you like. Keep in mind that the outside environment will affect your grow space—you may need to add heaters in the winter or fans and ACs in the summer. Other than that, you can start seeds whenever you like and flip them into flower whenever you like, depending on how big you want the plants.
Cannabis plants are considered seedlings until they begin to develop leaves with the full number of blades on new fan leaves. A healthy seedling should be a vibrant green color.
