Selecting The Ideal Location

Alright, let’s dive into one of the most crucial aspects of setting up your own cannabis grow room: selecting the ideal location. Obviously, an ideal location for one person may differ from another, but generally, most people choose to set up their grow rooms in a spare bedroom, a closet, or even a dedicated growing tent that can serve as the perfect environment for your cannabis garden. 


When selecting the ideal location to cultivate your marijuana seeds, there are several features to keep in mind to guarantee thriving growth and success: 

Lots Of Space

Your grow space should be large enough to accommodate the number and size of plants you plan on growing. It should also have enough height to allow your cannabis plants to grow vertically without running too close to the grow lights, which causes light burning.

Light Sealed

Next, your grow room should be light-sealed to prevent natural and artificial light from the outside world from flowing in. In other words, keep it as dark as possible. This is where spaces without windows, such as closets, really thrive. 

Reflective Interior

An ideal grow room will have white or reflective interior walls and ceilings to maximise light distribution within the grow space. Remember — dark surfaces absorb precious light which is essential for healthy and thriving cannabis plants. So, don’t waste any of those rays. 

Floor Drain or Waterproof Tray

Unless you’re looking to flood your home (bad idea), it’s essential to have a floor drain or waterproof tray in place. This will ensure that any runoff from your plants is effectively managed and prevents water damage to the surrounding areas.

Ventilation Openings

Ventilation openings are an absolute must-have in your cannabis grow room as it allows for proper airflow that is vital in keeping pesky mould growth at a minimum. It also helps to regulate the temperature in your grow room, so aim for at least two openings for ventilation fans, typically positioned at opposite ends of the room. 

Electrical Outlets

Make sure there are several electrical outlets available for plugging in equipment such as grow lights, fans, or anything else you need for your grow setup. Alternatively, you can provide an opening for power cords wiring to ensure safe and convenient access to electricity within the grow space.

Privacy and Security

Lastly, your grow room will ideally be situated in a quiet nook of your home that is private and secure — you don’t need any nosy neighbours sticking their beaks into your business! 

Investing In The Right Equipment


Now that you’ve (hopefully) identified the perfect space in your home to set up a cannabis grow room, it’s time to invest in all the equipment you’ll need for a successful harvest. First and foremost, the most important piece of equipment for any indoor grow operation is none other than lighting. Cannabis requires a lot of light to grow properly, so high-quality grow lights are crucial. LED lights are popular with indoor growers because they are energy-efficient and offer a full spectrum to which your plants need to grow.


And remember those ventilation holes we talked about? Well, another crucial piece of kit you’ll need is a combination of fans and exhaust systems to ensure proper air circulation and prevent mould and mildew from developing on your precious cannabis plants. 


Now that the two most important bits of kit are out of the way, here are some other essentials that will aid in keeping your cannabis plants in tip top condition: 

  • Carbon filters – these will help to eliminate odours from your grow room, keeping your cultivation discreet.
  • pH metre & pH adjusters – essential for maintaining the proper pH levels of your nutrient solution.
  • Temperature & humidity monitors – these monitoring technologies will allow you to keep track of environmental conditions in your grow room and make adjustments as needed.
  • Timers – these can help automates your grow lights, ensuring consistent light schedules for your plants.
  • Trellis netting or plant supports – these will help support heavy buds and promote even canopy growth, preventing overcrowding and maximising light penetration.
  • Pruning shears/scissors – essential for all gardeners, these tools can help trim leaves and prune your plants to encourage optimal growth and airflow.
  • Irrigation system – allows you to efficiently water your plants while minimising the risk of overwatering or waterlogged soil.
  • Propagation supplies – if starting from seeds or clones, you’ll need trays, dome covers, and a rooting medium to propagate new plants before transplanting them into your grow room.

Selecting Your Growing Medium

You’ve chosen your grow room location and you’ve invested in a variety of equipment and tools…now, it’s time to choose your growing medium — things are getting exciting!  As a general rule, plain old soil is probably the best medium if you are just starting out with growing cannabis. It is easy to use and provides a stable base foundation for your plants.


Another option is to go the hydroponic route — this method is gaining popularity because it delivers nutrients directly to the roots, resulting in faster growth and higher yields. However, creating the perfect hydroponic nutrient solution is a delicate art and requires precise monitoring of nutrient levels. As such, hydroponics is often considered the “next stage” for beginners, but  the choice is ultimately up to you.


Alternatively, coco coir might be the ideal growing medium for you if you want a happy medium between soil and hydroponics. Derived from the fibrous husks of coconuts, coco coir has the advantage of both water retention and aeration. Your plant roots will have a stable climate in which to grow, but there’s also plenty of room for good drainage and oxygenation. 

Cultivating Your Cannabis Plants

After all the preparation that’s gone into setting up your grow room and stocking it with equipment, you’re ready to start growing. Regardless of whether you choose to grow your plants from seeds or get them as clones, the first step to successful cultivation is lots of care and attention. 


Inspect your plants frequently for any sign of insects and pests, disease, or nutrient deficiencies and adjust our care routine accordingly. Remember to water your plants, but don’t overdo it. Overwatering plants will suffocate roots, causing root rot and other problems. Moreover, be sure to watch the temperature and humidity levels in your grow room because fluctuations can stress out your plants and retard their growth.

Harvesting and Curing Your Buds

Assuming all has gone well, it’s now time to harvest and cure your buds.


Generally, the timing of your harvest will depend on the strain of cannabis you are growing and your personal preferences. Most plants are typically ready to be harvested after 8-12 weeks of flowering. However, some strains can take longer, up to 16 weeks. You can also pay attention to the colour of the trichomes (the tiny resin glands on the surface of the buds) to know when your plants are about to be harvested. When the trichomes are mostly cloudy with a few amber-coloured ones, you can start harvesting your buds for drying & curing.


Drying and curing your cannabis buds is an extremely important step in the cultivation process. Proper drying and curing will help preserve the taste, potency, and smell of your buds, as well as vastly improve their overall quality. Hang your buds upside down in a cool, dark place with good airflow for about 7-10 days. Once the bud is bone dry, you can transfer it to an airtight container and store it in a cool, dark place for a minimum of 2-4 weeks for curing. Oh, and don’t forget to burp your containers on a regular basis in order to get rid of excess moisture and prevent mould growth.

It’s Time To Embark On Your Cannabis Growing Adventure 

Now that you’re equipped with all the know-how on setting up your own cannabis growing room, it’s time to get to work! Remember to be mindful of choosing the ideal location, buying high-quality equipment, and selecting the optimal growth medium for your plants.


After a few months of constant care, you’ll be rewarded with a generous harvest of premium-quality cannabis that will last you for months on end. Good luck and happy growing!
