How Long Does It Take to Grow Weed? A Beginner’s Guide

Have you been thinking about opening up your own plant nursery? Growing weed might seem as if it would take quite a while. However, depending on the plant, it might not take as long as you’d guess. Generally speaking, it’ll take at least two months before you’ll be ready to harvest. Harvests can also take much longer in other instances. Proper technique ensures you’ll be ready to harvest in as little time as possible. For that reason, we put together this guide. That way, once you’re ready to start planting, nothing will hold you back.

What Do You Need to Grow Weed?

Before breaking ground, you’ve got to understand everything you’ll need to accomplish. Plants grow better if they’ve been given access to the right conditions.


Fortunately, creating those conditions isn’t all that difficult. Thus, as long as your mindful, growing them should be a piece of cake.

Soil and Water

First, let’s consider the growing medium. In nearly all instances, that would be some sort of soil. Of course, you could also grow them hydroponically. Either way, you’ve got to plan how to water them and how to maintain their pH level.

Adequate Ph:Aim for a pH between 7.0 and 7.4. Anything outside of that range would be less than ideal.
Sufficient Water:When it comes to water, air on the side of caution. Although it’s essential, too much of it could be harmful.
Plants That Receive Too Much Water Could Wilt:Suppose you’ve been watering the plants a little bit too much. How could you tell? Well, most of the time, you’ll notice the leaves don’t look as perky. They may also start to lose a bit of their color. In either case, cut back on how much you’ve been watering them. They should start to appear as if they are rejuvenating.


Growing outdoors eliminates a lot of guesswork since the sun provides all the light. However, on some occasions, people would like to grow their plants indoors. To grow them inside, you’ll have to give them plenty of light. Usually, we suggest working with a quantum LED array. These provide light in the broadest spectrum so that your plants benefit maximally.

For Every Watt of Light, Expect to Grow 1 G of Weed:

Assuming everything is perfect, for each watt of light, your plants ought to yield at least 1 g. Experienced growers might get up to 1.5 g per watt in ideal circumstances.

Don’t Forget About Your Timers:

Are your seeds photosensitive? If so, don’t forget to install timers for your lights. Otherwise, those beautiful plants won’t bloom. Photosensitive plants must experience regular darkness to mature appropriately. Timers simplify things so that you don’t have to remember them.

Humidity and Ventilation

Humidity tells us how much water vapor is in the air. Low humidity dries things out. At the same time, excessive humidity promotes the growth of mold and mildew. Thus, for the best results, maintaining stable humidity is vital.

Humidity Shouldn’t Exceed 65%:We’d suggest maintaining the humidity above 55% without exceeding 65%. This range promotes plant growth without enabling molds to spread.
Dehumidifiers Could Be Helpful:How can you reduce the humidity if it becomes excessive? Typically, we’d suggest throwing a dehumidifier into the room for a little while. Keep an eye on your hydrometer to ensure it doesn’t drop too low.
Align Your Fans in a Circuit:Place fans at one end of the room so that they blow air out of it. This way, the air is constantly recirculated throughout the plant nursery.

How to Grow Weed?

If you’ve grown anything before, growing weed isn’t all that different. Nevertheless, plenty of people lack such experience. If you happen to be one of them, don’t let these concepts overwhelm you. Plants aren’t too complicated. In fact, once you’ve learned the basics, it’s rather straightforward. They grow in three stages. And, you’ve got to care for them in different ways during each.

Three Primary Stages

Seedlings:From the time he first planted them, seeds ought to take a few days before they sprout. At most, you shouldn’t expect them to take much longer than two weeks
Saplings:As young plants, they might appear a little different than you would expect. You’ve got to ensure all the right nutrients are delivered during this time. Otherwise, they won’t grow appropriately.
Mature Plants:Mature plants are simple to care for. Just provide them with plenty of light and water them, and they ought to do just fine.

Planting the Seeds

Putting them into the ground tends to be more intimidating than necessary. The following three tips should clarify things for you. That way, once you’re ready to start planting, nothing should surprise you.

Digging a Hole About Half an Inch Deep:

Typically, we’d suggest using a ruler of this part of the process. Stick it into the ground about half an inch deep. If you don’t have one of them, you can use your thumb. Staff your thumb into the dirt until it reaches the first knuckle. Then, put your seeds into that small depression.

Space Your Seeds About 6 Inches Apart:

Spaced appropriately, plants grow much faster, speeding things up in the end. Most of the time, 6 inches between your plants ought to be enough.

You Could Also Plant Them in Separate Containers:

Let’s say you’d like to get the most out of each of your plants. To do that, you’d want to plant them in separate containers. That way, they won’t be competing with each other for nutrients. Instead, they’ll have gotten all the space necessary for maximal growth.

Caring for the Sprouts

Sprouts pop through the soil after a few days. They won’t appear much different from anything else you’d place in the soil. However, provide them with all the necessary nutrients, and they’ll grow rapidly. Weed didn’t get its misnomer for no reason.

Soil Additives:Nitrogen can be a great additive. Often, plants won’t get enough of it from their natural soil. Adding some of it ensures they’ve got all the right stuff.
Ph Balancing:Anything above 7.5 on the pH scale would be acidic. Plants don’t tolerate acidic soil all that well. At the same time, if the pH drops below 7.0, the soil would be basic. Basic soil isn’t much better at promoting growth, either. When the pH deviates outside of that range, take action immediately. Otherwise, damage to your plants would be inevitable.

Preparing for the Harvest

Once your plants have gotten old enough, it’ll be time to plan for the harvest. Harvest produces the best results when you start planning for them as soon as possible. That way, nothing ought to be rushed.

Trimming Your Plants:Be careful while working with your plants. You wouldn’t want to damage the buds. Grab them close to the base of their petioles. Then, trim away any of the excess sugar leaves.
Drying Them:After gathering all the buds, hang them on your dryline. Several days on that should remove most of their moisture. Then, curing them comes next.
Curing Them:Similar to drying, curing also removes moisture from the buds. This time, put the dried buds into an airtight container. We’d recommend keeping them in a dark room. Open the jar once every few weeks. After about 2 months, they’ll be ready to use.

How Long Does It Take to Grow Weed?

Waiting until harvest seems to be among the most difficult parts of the process. Of course, it’s hard to blame them, considering the excitement in store.

Average Time to Harvest Would Be About 2 to 3 Months:

The fastest-growing plants might be ready to harvest in as few as eight weeks. The slowest growing plants could take twice as long.

Time to Harvest Depends on the Strain

Certain strains grow a lot faster than others. In general, you’ll find that Sativa dominant strains tend to grow the quickest. On the contrary, hybrids tend to take the most time to reach full maturity.

Indoor Plants Mature Far More Rapidly:

Wherever you decide to grow them will also have an impact. Thus, if you’d like them to grow as quickly as possible, planting them indoors would be the best idea.

Some Strains Grow Rapidly

Compare different strains to see which of them grows the fastest. We’ve got information on all our seeds, including the average time to harvest.

Fast-growing Strains Could Be Ready in As Few As Eight Weeks:

Would you like something that will be ready in fewer than two months? In that case, then we’d suggest collecting something with an eight-week harvest time. Those ought to be ready fast enough for your expectations.

Others Take a Lot Longer

Waiting for your first harvest is such a unique occasion. Pay attention while shopping for different seeds because some of them can take a long time.

Sometimes, It Could Take 16 Weeks or Longer:

At the most, you might be looking at four months. Such a long time might dissuade some growers. However, if you’d like things to go faster, look for another seed. That way, you won’t be stuck waiting around.


How to Ensure You Will Have a Bountiful Harvest

Packed to the brim, overflowing baskets ought to be the best sign of a successful harvest. To get the best results, you’ve got to provide plants with the ideal conditions. Fortunately, since we know how to grow them, creating such conditions isn’t complicated.

Proper Nutrition:Check out our page to see a full selection of soil additives. Have those plants been developing yellow spots? That could be a sign they’ve been running low on phosphorus. Throw a little bit of it into their soil, and they’ll be good as new in no time.
Fruitful Environment:How much light have your plants been receiving? Unless they’ve been getting more than enough, they won’t grow to their full potential. Put at least 100W per plant in your nursery.
Regular Care:You’d be surprised at how many plants suffer due to mold and mildew. Letting the air stay humid creates a lot of potential problems. That’s why we’ve always told people to use a dehumidifier. Otherwise, molds and mildews could ruin the whole season.

Other Growing Options:


What does it mean to grow something hydroponically? Whenever plants are grown hydroponically, their roots are placed into water directly. Instead of planting them in soil, they’ll be suspended above a container of water.


Planting this way provides them with a far more efficient nutrient delivery system. Thus, compared to traditional techniques, yields are far greater. Nevertheless, you’ll have to spend quite a bit more to get started.

Planting things this way also requires a lot more attention. Unless you’ve got the time, it might be better to do things traditionally. Still, for those interested in the largest harvests, hydroponics would make a ton of sense.

Indoor Growing

Perhaps, you’ve got an extra closet, sitting unused in the back. With one of those, you got enough room to plant a couple of saplings. Not to mention, growing things indoors tends to be much easier. Indoor environments don’t fluctuate nearly as much as outdoor environments.

So, to simplify things, consider planting stuff indoors. We’ve found people tend to have better results that way. Check out some of our other guides if you’d like to learn more about indoor growing techniques.
