What's the fastest way to grow weed

If you are using weed either as a stimulant or medicinally, in all likelihood you have already thought about growing your own. Fortunately, growing weed indoors isn't as difficult as is often portrayed. Here are 10 easy steps to get started growing weed indoors today:


The first step in growing weed indoors is finding a good grow space. While novice growers often think they need a lot of space to support their plants, that's actually not entirely true.

In fact, it's surprising to learn that great weed can be grown almost anywhere, including closets, garages, basements, and guest rooms.

Of course, a larger room that allows you to distribute your plants nicely and to be able to work more comfortably is ideal. But don't forget that larger rooms also need more lighting and ventilation, which in turn increases costs.

When choosing your indoor grow space, keep the following things in mind:

  • Cannabis plants have strict light needs. Your plants will need strict periods of darkness, during which time no external light should penetrate the grow space and disturb your plants. This can cause stress and affect plant health and yields.
  • Temperature / Humidity: When growing cannabis, temperature and humidity are extremely important factors. You will want to grow in a room where you have as much control over temperature and humidity levels as possible in order to maximize the potential of your plant (s).
  • Cannabis plants need plenty of airflow. Air circulation helps keep temperature and humidity levels stable throughout the grow room. Poor air circulation can create a lot of problems for your plants, putting them at risk of mold and other diseases.


Once you've found the right grow space, you can start preparing it for your plants. The first step in doing this is installing reflective walls.

Reflective walls help focus as much light on the plants as possible, resulting in large, potent yields of delicious bud. This essentially allows you to increase the power of your lamps without driving up your electricity bills.

In fact, reflective walls can increase the power of your lamps by up to 30%. Best of all, adding reflective walls is actually really easy.

There are a few options for installing reflective walls in your grow space:

  • Grow tents: Grow tents are a very popular option among indoor growers. They come with reflective walls specifically designed to cope with cannabis grow lights. This means they won't melt due to the heat from your grow lights and will have the best reflectivity of any of the options listed here. Grow tents are also very easy to set up and usually come complete with everything you need to produce a great harvest. Just be on the lookout for any bubbles or pockets that form in the tent wall as these will decrease the reflectivity in your room.
  • Matt white latex paint: Matt white latex paint is available at every painter's supply store and offers great reflectivity (between 85 and 95%). It's also very easy to use and doesn't create pockets or bubbles (like grow tent walls) that can reduce the reflectivity of your grow space.
  • Panda Plastic (black and white plastic film): Panda Plastic is a type of plastic film that you can easily install along the walls of your grow room using nails or Velcro. It also has great reflectivity values, similar to matt white latex paint (85 to 95%). However, Panda Plastic can get very expensive, especially if you need a lot of it. Also, the plastic can melt if it gets too much heat from your grow lights. As with grow tent walls, avoid letting the plastic form bubbles or pockets.


Keep in mind that cannabis plants are very sensitive to light, especially during their dark phases. Any light that enters your grow space during the dark periods can disrupt the rhythm of your plants and cause stress.

Growers often discuss how light leaks affect plants. Some argue that even the smallest leak can stress your plants unnecessarily, while others think it makes the problem bigger than it is.

We tend to believe the former, and we always advise novice growers to take the time to check their grow room for light leaks.

Light leaks can ultimately stunt plant growth and affect both the size and quality of your crops. In some cases, light leaks can also trigger hermaphroditism.

Checking light leaks is easy. If you're growing in a room, just turn on your lights, stand outside the room, and look for tiny rays of light shining through to the outside. When light comes out of your room, you can be sure that it will also come inside.

Then do the opposite: stand in your dark grow room and look for incoming light. You will usually find light leaks around the doors and windows.

If you're growing in a tent, closet, or any other room you physically can't fit into, do the test from outside the grow room. Look for any rays of light emanating from the space of your grow lights.

If you find any leaks, make sure to cover them up. How you do this will depend on the size and location of the leak. Some common options include:

  • Blackout Tape: This stuff is inexpensive and can be easily applied to small leaks around the cracks in doors and windows, as well as cracks in reflective walls.
  • Panda Foil and Poly Foil: This is great for covering larger leaks and can be used to cover larger areas like entire doors and windows. It is more expensive than blackout tape, but it is also very effective.


If you're not fortunate enough to live in an area where weed growing is legal, chances are you're going to want to keep your venture a secret. Therefore, you will want to minimize the smell of your plants.

One of the best ways to do this is by using an air filter. These filters literally filter the air in your grow space, essentially clearing it of any odors.

Most cannabis growers opt for activated carbon filters. These are the same type of filters that are used to filter out the smell of car exhaust, so you can be sure that they will do a good job of cleaning the air in your grow room.

The science behind these filters is simple: the air goes through the filter, which contains activated carbon that absorbs odors and other impurities from the air before the air is pumped out again.

The typical way to install an activated carbon filter is to attach it to your exhaust air system (see below). This way, hot air from inside your grow room is drawn through the filter and cleaned before it gets outside.

If you only grow a plant or two, you will likely be able to mask the smell in your grow space without the use of a filter. However, every medium to large grow room should use a high quality filter and an exhaust system so as not to attract unwanted attention.


At the beginning of this article we mentioned the importance of air circulation for cannabis plants. Installing a good quality ventilation system is the best way to ensure that your plants get adequate fresh air throughout their growth cycle.

In nature, cannabis plants thrive in a gentle breeze. This protects the plants against mold, bud rot and powdery mildew, as well as against pests such as fungus mosquitoes, spider mites and more.

Furthermore, constant air circulation can also help to control the heat / humidity around the plants and to keep moisture away after weather events such as rain. Finally, gentle winds also help the plants develop strong branches and stems as they sway and bend in the breeze.

If you grow cannabis indoors, your plants won't have to deal with rain. However, they are still susceptible to many of the pests and diseases that outdoor crops struggle with. Therefore, you will need to install a good quality ventilation system to provide your plants with just the right amount of air to circulate.

The easiest way to increase airflow in your grow room is to use fans. Most growers will strategically place a few wall fans along their grow space to create a gentle yet steady breeze over the entire canopy of their plants.

Also, to help control the heat and humidity within the grow space, most growers will install exhaust systems designed to draw hot, old air out of the grow space and make room for fresh air.

Most growers will install their exhaust system above their grow light, which is where hot air usually accumulates. Then they'll usually use a couple of regular fans to let the air move around the room.

Here are some tips for installing fans and exhaust systems in your indoor grow space:

  • Do not point strong fans directly at plants. Instead, aim to create a steady flow of air over the canopy.
  • Check all areas of your grow space after installing the fans to make sure the air is moving through the entire room / area.
  • Remember, strong winds can cause wind burns and stress for your plants. Stick to a gentle but steady breeze.


A grow lamp is the center of an indoor grow project. After all, cannabis plants need plenty of light to grow and produce delicious buds.

Grow lights should be installed so that they can reach as many of your plants as possible. You will likely need to experiment with the positioning of your plants to ensure that all of them are well lit.

Keep in mind that grow lights can get hot and should not be placed near any flammable material.

There are hundreds of grow lights available for you. Choosing the right one will depend on the size of your grow room, your cannabis experience, and your budget.

Here are some of the most popular lighting options that can be used for growing weed indoors:

  • Compact fluorescent / energy saving lamps: These are arguably the most popular lighting option among novice growers. They're reasonably priced but don't have the power of professional grow lights like the following.
  • Fluorescent Tubes (T5 / T8): T5 and T8 fluorescent tubes are typically designed for use on plants that require a lower light intensity than cannabis. Hence, they usually need to be installed very close to the top of the plant to be effective. Nonetheless, some growers get good results with these lights.
  • LED grow lights: LED lighting is much more expensive than the fluorescent option mentioned earlier. However, they are more powerful and can provide a lot of light to your plants as long as you use them properly. If you should decide to go the LED route, don't forget to research your specific lamp model to make sure you're installing it properly.
  • Metal halide (MH) and sodium vapor lamps (HPS): These are (at least for now) the best grow lights for cannabis. They are very powerful, relatively cheap, and particularly easy to set up. Most indoor growers opt for either metal halide or sodium vapor lamps.


Above we covered the larger pieces of equipment you will need to install in your grow room. Once you've got all of that organized, it's time to source and set up all of your small pieces of gear and accessories.

Here is a list of some of the additional equipment you will need for your indoor grow space:

  • Pots: The size depends on how big you want your plants to be.
  • pH meter: Used to measure the pH of your soil and ensure a good environment for your plants.
  • Thermometer / Hygrometer: Used to measure the temperature and humidity levels in your grow room.
  • Soil / Growing Medium: There are several growing media that are suitable for cannabis plants. Choosing the right one will depend on your skills as a grower and your preferences.
  • Scissors: Used to prune your plants.
  • Spray bottle: Used to apply pesticides.
  • Bucket.
  • Nutrients and fertilizers: Used to fertilize plants.
  • Timers: For the automatic control of your grow lights.


Follow the last seven steps and you will have a decent grow room. Now all you will need is a few plants and you are good to go!

Start by choosing which strain you want to grow. There are thousands of strains, each with their own advantages and disadvantages. Which one you choose is completely up to you. Most importantly, grow a strain that you will love to smoke, but that still suits your experience and grow space. If you use our strain database, you can learn more about the different cannabis strains.

Once you've chosen a strain, it's time to grow your plants. There are a couple of ways you can do this, including:

  • Growing straight from the seed: It's very common, but it means you need to know how to properly germinate seeds. If you do, we recommend using feminized seeds to avoid dealing with males (unless you plan to breed).
  • Using Cuttings: Some growers choose to buy cuttings to avoid germinating their own seeds. If you choose this option, be sure to get your cuttings from a reliable source.


Once you've started your seedlings / cuttings, it's time to be patient. Growing great weed takes time and you will need to pay close attention to the needs of your plants.

Cannabis plants have two different growth phases. The vegetative phase is characterized by vigorous vegetative growth in which the plants develop flower points. Then, after about 4 weeks, your plants will move into the flowering phase during which they will focus on developing large, beautiful buds.

The exact details of growing cannabis will vary depending on the strain you have chosen to grow and the specific phenotypes you are working with. The most important thing is to pay close attention to your plants and to regularly read our growing articles for tips on training, nutrition, pruning and much more.


After 6 to 12 weeks, your plants will usually be ready to harvest.

At first you will notice that your buds will stop developing white hairs. Your plants should also be very fragrant and their buds should look very fat.

Next, you'll notice that the white pistils slowly darken and usually turn slightly red or orange. These hairs will also begin to curl inward as the buds mature.

You should wait until at least 40% of the pistils on your buds have started to darken. This marks the beginning of the harvest time window. Flowers harvested at this point will usually be more uplifting and slightly less potent.

Some growers delay the harvesting phase a little longer until 50 to 70% of the pistils have darkened. This should be when the THC levels in the buds have peaked. Buds harvested at this point will produce a more relaxing effect.

Once you've harvested your buds, it's time to prune and dry them. This can take up to 2 weeks. You should slowly dry your buds by hanging them upside down and storing them in high quality, sealable jars once they're done.

Then, once you've harvested and cured your buds, it's time to sit back, light one, and enjoy the fruits of your labor!
