If you’ve been buying weed for a long time, you likely already know the short answer to this question. Most people will tell you that it takes as long as it takes, but then again, most don’t realize that there are a lot of factors involved in the growing process of a weed plant. When it comes to asking how long does it take to grow a weed plant, the short answer is “as long as it takes”, and it’s the most frustrating answer to get to that question. In this article, we’re going to go into a little more depth than “as long as it takes”! We’re going to talk through the time it takes to get from day 1 of planting a seed to smoking your new harvest and we’re going to talk about what is included in the process and what factors will affect the time it takes for your weed plant to be ready to smoke.

How long does it take to grow a weed plant?

From day one and your decision to grow your own weed plant, you’ll find that it can take anywhere from eight weeks to seven months to get your harvest rolled into a blunt. It’s for this reason that most producers won’t pinpoint an exact date for the plant to have grown; the bigger plants take more time and anything can affect the growing time, from the strain and setup to the size of the plants. There is no exact answer to how long does it take to grow a weed plant here!

For indoor growers, the particular weed plant could take 3-5 months to grow the cannabis, and this includes the time it takes to get from seedling to harvest, plus the couple of extra weeks or months it takes to cure the buds. You want to take that time to get the better smelling, more potent buds. When you grow your weed for the first time, you should consider you need extra time to get the equipment and seeds all sorted out. This takes extra time, and you should consider that how long you should grow your marijuana really depends on the style of growth, the yield you desire and the strain. The life cycle of a weed plant is important to note that most outdoor strains depend on the weather as much as the time of year you plant.

Growing your weed: seedling to smoke

There are a few stages to consider when it comes to how long it takes to grow weed. In this section, we’ve detailed each of those stages as well as what it means for your weed plants.

Day 1-7

This is the time it takes for seed germination. You need to learn as much as possible about fail-proof methods for your seeds to germinate properly. They’ll germinate in either soil or a hydroponic chamber.

Week 4-8

This is the vegetative stage of the process. In this stage, only the stems and leaves are growing. Most of the indoor weed plants will vegetate for 4-8 weeks, and seedlings will begin to flower at around 3 weeks from germination, but the actual plant will be pretty tiny as a result. Almost all growers will ensure that the plants vegetate a little longer to get a larger plant as a result. This will mean bigger quantities of weed later on. You only need to ensure that there is enough light covering all of the bud sites to get them to grow.

Week 8-10

This is average for the flowering stage, but it does depend on the strain of weed you’re growing. Plants begin to bud around this timeframe, and the length of this stage tends to be 8-10 weeks, but it can be longer depending on the strain. Some of the strains out there can take months before they need to be harvested.


This stage is all about that sharp smell you’re looking for. When the buds are harvested, they should be dried for around a week before being moved into glass jars. This helps them to mature and you need to allow this 14+ days if you want the very best quality.

This is the part of the process that really improves the taste and smell of the weed and achieves the best possible quality. You want to reduce the chance of any headaches and “speedy” effects, and this is not a step that you want to skip!

Preparation time

It can take up to 2 weeks to get all of the equipment that you need and have it all show up in the mail. If you buy local, it won’t take so long but you still have to set it up and get it ready to go. Once you have the right supplies, you can get things set up in your growing area. You should have a dedicated area for growing your plant, as you want this to go right. You then have to source the right seeds for your weed plants. Yes, each type of seed will grow different plants, and you can expect to wait up to four weeks for those seeds sto arrive depending on the location from which you buy them.

If you want to harvest quickly, you could buy your seedlings in the flowering stage, but just remember that this can make for much smaller plants and you want to avoid that! You want to vegetate for at least a month so that you can get the best possible results too. At least 18 hours of light each day will ensure that you get the best quality bud at the end of the growing cycle.
