Worry not, we have got you covered. We will give you an in-depth guide to everything you need to know about growing cannabis in your home.

First, You Need to Choose Your Strain

The first and most important step in growing cannabis is by selecting your ideal strain. In this step, you will need to be very careful. It’s because different strains require different environmental conditions for them to strive. For instance, indica cannabis strains are likely to grow to be quite bushy. You will, therefore, need to prepare this environment in advance.

Always consider aspects the following when choosing your strain;


  • The estimated size of a full-grown cannabis plant


  • Your size of the garden


  • The lighting


  • The expected yield will it be big or small


  • The effectiveness of the strain


These factors will give you insight on the type of marijuana strain that you wish to grow. If you do have the resources, you can also opt to grow a couple of different strains.

Step 2: Select a Grow Room for Your Plants

The next step after identifying your ideal type of strain is designating space for growing your cannabis. It’s not a must that you build a greenhouse. You can find a suitable space in your basement, closet, or even backyard. As long as you tailor that “space” to meet the conditions for the growing of marijuana.

For beginners, it’s advisable that you start small and gradually increase the number of plants as you gain experience. Why start small? It’s because, in case of any setback, the loss will be minimal. The selected space for growing your cannabis should be able to accommodate the plant when it’s fully grown and other equipment such as fans and grow lights.

The ideal space for growing marijuana should be light tight, clean, cool and dry, stealthily located and convenient. The environment plays a key role in ensuring the growth of the plant. If it doesn’t meet the criteria above, you should then try to create such an environment. A grow tent is a better alternative if you are growing cannabis on a small scale level and if you are doing it indoors. However, you should choose a greenhouse, if you intending on growing a lot of plants.

Step 3: The Grow Lights

Similar to all other plants, marijuana also requires light in order for it to flourish. Because you intend on growing it indoors, you will need to use grow lights. There are different types of grow lights and you should choose which light setup is suitable for your plants.

Below are the most popular grow lights.

  • HID Grow Lights – fully known as high-intensity discharge lights, they provide a spectrum that is much closer to that of the sun. They are a great alternative but produce some heat. It’s best if you use them alongside exhaust fans.
  • Fluorescent Grow Lights – these type of lights are also a favorite of most indoor cannabis growers because they are affordable and don’t generate a lot of heat. The only setback of this lighting system is that they are less efficient when it comes to light produced per watt of electricity.
  • LED Grow Lights – amongst this list of grow lights, LED stand out to be the best. They don’t generate heat, they use the least amount of electricity, produce a full spectrum of light and are long-lasting. The problem is that they are quite expensive.

You can choose one of the above grow lights depending on your budget and preference. Nonetheless, you need to be a bit cautious when purchasing them because nowadays there are a lot of grow light manufacturers. Some are genuine whereas others are only after exploiting innocent indoor gardeners.

Step 4: The Grow Medium

You need to find the proper medium where your plants will grow in. in this step, you will have three options. You can either use soil, hydroponics or coco. The three are good mediums but they all have their advantages and disadvantages.

Our first medium alternative is the good old fashioned soil. It’s a great source of nutrients. Moreover, if it’s your first time growing cannabis then the soil will enable you to take readings and much more. But, you must have patience when it comes to soil because it will take longer for your plants to grow.

Hydroponics is a less messy way of growing cannabis compared to soil. Moreover, your plants will grow faster than growing them in the soil. It also encourages fast nutrient intake by the plant. Using hydroponics will however extreme care to avoid growth of fungi, mold or even root rot.

Coco, on the other hand, lies in between soil and hydroponics. It’s great at holding nutrients compared to hydroponics but not as much as soil. It also enables plants to grow faster than soil.

Step 5: Air Supply

CO2 is also another element that is very essential for the growth of your cannabis. It aids in photosynthesis. You should ensure that is a fresh air supply in your grow room at all times. Having an exhaust fan is an excellent way of ensuring this happens. The exhaust fan should be strategically placed in one corner and on the other end, you can place an air inlet that will filter the air getting in. if you have a relatively smaller grow space, you can then just use the ordinary fan to ensure air moves freely.

The fan also plays a great role in minimizing and regulating the heat generated by the grow lights. The typical temperature for the growth of cannabis is in between 70degree F and 85 degrees F.

Step 6: You will need to Install Control and Monitoring Equipment

Now that you have all the above four requirements, you will need to take control of the environment and monitor the progress of your plant. For beginner cannabis growers, all that you will need is a timer for the grow lights and a thermostat for the exhaust fan. However, for large-scale growers, you must install units that will regulate the temperature, light, CO2, and humidity.

During the growing stage, the lighting should be on for around 16 to 20 hours per day. But, when they start to bloom, you should reduce the lighting period to 12 hours.

A timer will help you know when to switch on or off the lights for your plants. You should be consistent with this to avoid stressing of your plants. The thermostat, on the other hand, will allow you to set the desired temperature and you can then plug it into the fan. Having a PH kit is also essential because it will help you determine the acidity or alkalinity of the water, soil or nutrients. The required PH level for cannabis growth is between 6 and 7.

Final Step: Water, Feed Your Plant with Nutrients and Watch it Grow

When you finally reach this step, all you have to do is water your plants regularly and feed them with all the required nutrients. The main nutrients for your cannabis are Nitrogen, Phosphorous, and Potassium. Copper, magnesium, and iron also make good micronutrients for the growth of your cannabis. Also, check the chlorine level of the water before pouring it onto your plants.

The above is everything you need to know about the growth of cannabis in your home. As you can see it’s quite simple but it requires consistency and determination. Nonetheless, it’s doable. All you have to do is just start. With time, you will gain experience and you can increase the number of cannabis plants. Growing cannabis is a whole lot fun than laborious, especially if you think about the numerous benefits it will provide you with.
