Decide on a grow method

One of the most common ways to grow cannabis is by growing cannabis seeds. You will need to decide on a grow method before you can start growing cannabis seeds. Some common grow methods include hydroponics, soil, and aeroponics.


To grow cannabis indoors, you’ll need to start with a grow room or grow tent. These are designed to create an optimal growing environment for your plants, and they come in a range of sizes to accommodate small-scale and large-scale growers. You’ll also need to invest in some key pieces of equipment, including grow lights, fans, and an exhaust system.

Once you have your grow room set up, you’ll need to decide on a grow method. The most common methods for growing cannabis indoors are soil, hydroponics, and aeroponics.

Soil is the simplest and most forgiving grow method, making it a great option for beginner growers. Hydroponics is a more complex method that can yield quicker results, but it requires more knowledge and experience to set up and maintain. Aeroponics is the most advanced grow method and it can yield the highest yields, but it is also the most difficult to set up and maintain.

No matter which grow method you choose, there are a few key things you need to do to ensure your plants thrive: provide them with adequate lighting, water them regularly, keep the temperature and humidity at the right levels, and ventilate the space properly.


If you live in a state where it is legal to grow cannabis, and you have the space to do so, then growing outdoors may be the best option for you. Outdoor cannabis plants can grow very large and produce a lot of bud. The main drawback to growing outdoors is that your crop is subject to the whims of Mother Nature—if it doesn’t rain, your plants might not get enough water; if it gets too cold, your plants could die; if there are pests in the area, they could decimate your crop. Luckily, there are ways to mitigate these risks (e.g., by choosing a strain that is resistant to cold or pests).

Another consideration is that growing outdoors means that your plants will be visible to anyone who happens to walk by, so security is a concern. If you decide to grow outdoors, make sure to choose a spot that is not visible from the street or any public areas.


A greenhouse is a great option for the new cannabis grower. It offers complete control of your growing environment and can be as simple or elaborate as you desire. Greenhouses can be purchased or built to suit your needs and budget.

Advantages of a Greenhouse:
-Complete control of your growing environment.
-Can be as simple or elaborate as you desire.
-Ideal for small scale growing.
-Inexpensive to set up and maintain.

Disadvantages of a Greenhouse:
-Must be located in a suitable location with adequate sunlight.
-May require additional ventilation and cooling in hot climates.

Choose a growing medium

No matter what growing method you choose—soil, hydroponics, or aeroponics—you’ll need to start your cannabis plants in some type of growing medium. Growing mediums provide support and nutrients for your plants, and they can also help to regulate the temperature and moisture of your plants’ root system.


One of the most important factors to consider when growing cannabis is choosing the right growing medium. The three most popular choices are soil, coco coir, and hydroponics, each with their own set of pros and cons. Soil is the most forgiving medium and is therefore a great choice for beginners. It holds moisture well and provides nutrients to the roots, but it can be susceptible to compaction and pests. Coco coir is a favorite among experienced growers because it drains well and is easy to control, but it can be expensive. Hydroponics is a popular choice for those looking to maximize yield, but it requires more attention and experience to set up and maintain.


Hydro growing, often called hydroponics, is a method of growing plants in a soilless solution. The plant’s roots are suspended in water that contains all the nutrients the plant needs to grow. There are many advantages to growing cannabis in hydro, especially if you are growing for medical purposes.

One of the biggest advantages of hydro is that it is possible to control the nutrient levels very precisely. This is important because different strains of cannabis have different nutrient requirements. By carefully controlling the EC and pH levels, you can make sure that your plants are getting exactly what they need, when they need it. This leads to bigger yields and better quality buds.

Hydro also allows you to grow your plants faster than in soil because the roots have direct access to all the nutrients they need. This means that you can go from seed to harvest in as little as two months.

There are some disadvantages to hydro growing, however. It can be more expensive to set up a hydro system than a soil system, and it requires more knowledge and experience to get right. If you don’t have enough experience, it is easy to overwater or over-fertilize your plants and cause them serious damage.

Select your grow lights

To get started, you will need to purchase some quality cannabis seeds. You can find these seeds at your local dispensary or online. Once you have your seeds, you will need to select the right grow lights for your setup. Cannabis seeds need a lot of light to germinate, so make sure you select a grow light that is powerful enough for your needs.


High Pressure Sodium (HPS) lights are popular for cannabis cultivation because they emit a spectrum of light that is beneficial for plant growth. HPS lights are available in different wattages, ranging from 150-watts to 1000-watts. The higher the wattage, the more light output and the higher the electricity bill. HPS lights produce light in the red and orange part of the spectrum, which is ideal for plants during the flowering stage. HPS bulbs also emit a lot of heat, so be sure to use a ventilation system to remove the heat from your grow room to prevent your plants from getting too hot.


MH or Metal Halide grow lights are perfect for the vegetative stage. MH grow lights emit a blue spectrum light, which is perfect for growing sturdy leaves and stems. The MH spectrum also promotes short internodes, which means your plant will grow more compact and stocky.

Once your plants have begun to flower, you will want to switch to a HPS or high-pressure sodium light. HPS lights emit a red/orange spectrum light that is perfect for the flowering stage. The red/orange light encourages your plant to produce more buds and flowers.


LEDs are newer technology and are becoming more and more popular for growing. They are more expensive than CFLs, but they use less energy and last longer. They also emit very little heat, so you won’t have to worry about your plants getting too hot. LEDs are available in different “kelvins” or color temperatures, so you can choose a light that will mimic the sun more or less closely.

Get your cannabis seeds

You need to start with getting your hands on some quality cannabis seeds. You can find these at a local dispensary or you can order them online. Once you have your seeds, you will need to decide on a growing method. You can grow your cannabis plants indoors or outdoors.

Buy from a reputable source

If you want to grow your own cannabis, you’ll need to purchase some seeds first. But with so many different seed banks and sellers out there, it can be hard to know where to buy from. Here are a few things to look for when choosing a reputable seed source:

– A wide selection of strains: A good seed bank will offer a wide range of cannabis strains, giving you plenty of choices for your grow.
– Good reviews: Take some time to read reviews of seed banks before making a purchase. This will give you an idea of the quality of their products and customer service.
– pricing: Compare prices between different seed banks to find the best deal. However, be sure to also consider the quality of the seeds when making your decision.
– shipping: Make sure the seed bank ships to your country before placing an order. Some banks only ship within the US or Europe, for example.
– customer service: A good seed bank will have friendly and helpful customer service representatives who are available to answer your questions.

Select the right strain

Selecting the right cannabis strain is critical to having a successful grow. With so many strains available, it can be hard to know where to start. But don’t worry, we’re here to help.

There are three main factors to consider when selecting a strain:

-Flowering time: The amount of time it takes for the plant to flower and be ready for harvest.
-Yield: The amount of usable product you can expect from each plant.
-Climate: Make sure the strain you select can thrive in your grow environment.

Start your cannabis seeds

To start your cannabis journey, you’re going to need some seeds. You can either buy them online or find them in person. Once you have your seeds, you’ll need to germinate them. Germinating your seeds is simple and only requires a few supplies. This guide will show you how to start your cannabis seeds so that you can grow your own plants.

Soak your seeds

The soak is a crucial step in getting your seeds to germinate properly. You will want to start by filling a cup with lukewarm water and adding your seeds. Let them soak for about 24 hours, making sure to check on them periodically and top off the water as needed. After the soak, your seeds should have swollen and cracked open, revealing the beginnings of their taproots.

Plant your seeds

The first step to germinating your seeds is to plant them. You can do this by placing them in soil or, my personal favorite method, planting them in coco coir.

To plant your seeds in soil, simply poke a small hole in the center of your soil about ¼ inch deep using your finger or a pencil. Then, place your seed in the hole and lightly cover it with soil. Add water until the soil is evenly moist and place the pots in an area where they will receive indirect light.

To plant your seeds in coco coir, first soak your coco coir in water until it is saturated. Then, hold the coco coir in your hand and make a small divot or indentation about ¼ inch deep using your thumb. Place the seed in the indentation and lightly press the coco coir around it until it is covered. Add water until the coco coir is evenly moist and place the pots in an area where they will receive indirect light.

Water and fertilize your plants

Water and fertilize your plants regularly. Start with a low-nitrogen fertilizer and increase the amount of nitrogen as the plants grow. If the leaves start to turn yellow, that’s a sign that the plant is getting too much nitrogen.
