Successfully growing indoors is a bit like orchestrating a plant symphony. 🎶 You need the right notes, the right instruments! 🎻 The magical recipe includes special techniques and futuristic equipment to recreate the perfect ambiance your plants love.
What is Indoor Culture? 🌱
Imagine a corner of nature in the heart of your home, where plants thrive in a pampered ecosystem. Indoor cultivation is this plant bubble within your home, an oasis of greenery where the magic of growth operates all year round.
Advantages of indoor gardening 👨🌾
Indoor gardening is a ticket to a botanical adventure without seasonal boundaries. Goodbye to the vagaries of the climate, hello to absolute control over growing conditions. Light, temperature, humidity: everything is in your hands to pamper your plants and reap benefits in abundance.
Managing pests and diseases? Child's play compared to the outdoor garden. With well-thought-out precautions, your indoor garden remains an impenetrable fortress for undesirables.
And the icing on the cake? Fresh products, at your fingertips, to enhance your dishes. Succulent tomatoes or aromatic herbs picked on demand, this is the luxury that indoor gardening offers you.
Create the ideal conditions for indoor cultivation 🍃
Now, let's talk seriously, or rather brightly:
The importance of lighting in indoor gardening
Light is the magic wand that transforms the daily life of your plants. Choose carefully between:
- Fluorescent Lamps : Gardeners choose them not only for their soft, warm glow, but also for their lower cost than most of their horticultural counterparts. They offer a very beneficial light spectrum for plants , and, while emitting discreet heat, they act as ideal accomplices for the germination of seeds .
- High-intensity discharge (HID) lamps : High-intensity discharge (HID) lamps stand out as champions of lumens , this unit of light measurement. HIDs have undergone constant technological developments. However, it is essential to note that these lamps generate a significant amount of heat.
- Light-emitting diodes (LEDs): Light-emitting diodes, commonly known as LEDs , have entered the cultural realm with a bang. More and more farmers are now opting for this technology . Although their light intensity may seem lower than that of high intensity discharge (HID) lamps, LEDs are a more efficient and economical choice . Despite their potential need to be used in greater numbers, the proper configuration of LEDs can achieve results that often surpass those obtained under HID lighting.
The photoperiod , for its part, is the conductor of the plant ballet. By manipulating the weather of light and dark, you orchestrate the symphony of growth, flowering and fruiting. (more information in our guide page 41 )
The basic rule is: plants continue to grow
grow when the days are long, and begin to produce flowers
when we give them more darkness.
The role of air circulation and ventilation 🎈
Air is the breath of oxygen for your plants, but also the key to a healthy indoor garden.
Choosing the right fans for your indoor grow room is a crucial step, closely linked to its dimensions. In a grow tent , floor space is often limited , precluding the option of a traditional fan. Instead, opt for a small model fixed in the upper corner , ensuring efficient air circulation.
An expert tip to remember: avoid positioning fans directly above your plants. Favor an arrangement that allows air to circulate around or below the plants. This strategy will help maintain optimal humidity levels by preventing any unwanted drops.
Temperature and humidity control 🌡
Imagine that your plants have their weather preferences, much like you have your favorite clothes. Their comfort depends on a well -adjusted temperature and humidity . Thermostats, air conditioners, humidifiers, and even ultrasonic misters are your allies in this weather dance. For example, cannabis grows at daytime temperatures between 20 and 30 °C. During the night, or during dark hours, it is normal for this temperature to drop a little. However, the temperature should never drop below 16°C in your grow room. (more information in our guide page 74 )
Humidity level is the precise measure of the quantity of water present in the air . As an indoor growing enthusiast, you need to be able to evaluate the relative humidity content of your growing room based on your feelings. An overabundance of humidity will be felt instantly, while an overly dry atmosphere can be a little harder to detect.
Cannabis , a demanding being, favors specific humidity levels at different stages of its growth cycle. During the vegetative phase, the optimal humidity level fluctuates between 40 and 60 %. During flowering , it is recommended to maintain humidity between 40 and 50 %. Finally, during the final weeks of flowering , the ideal humidity is between 40% and 45% . Careful control of these parameters will greatly contribute to the prosperity of your indoor culture. (more information on humidity levels in our guide page 7 6)
The importance of watering 🚿
One of the common mistakes made by novice growers is a tendency to overwater. Although plants have a notable water appetite, it is likely that they do not need the amount that many novice gardeners imagine. The demand for water evolves throughout the different stages of their development. (more information in our guide page 44 )
Water, the elixir of life for your plants! Water sparingly, as too much or too little can lead to root disasters. Listen to your plants, observe their needs, and water with love.
Nutrients and diet 🥫
Just as humans need specific nutrients for growth, plants follow the same logic. Rather than talking about “plant health,” it is more accurate to refer to “soil health.” If the soil contains the right nutrients, plants will thrive. By ensuring an adequate concentration of nutrients in the soil, you also prevent any pH imbalance.
Cannabis, for example, requires three essential nutrients:
- Nitrogen (N)
- Phosphorus (P)
- Potassium (K)
Each fertilizer or soil has an “NPK” value, representing the ratio of these nutrients. Secondary nutrients such as magnesium, calcium and sulfur are also crucial. ( learn more about nutrients on page 65 of the guide )
Identifying and Correcting Nutrient Deficiencies in Indoor Culture
Correcting nutrient burn is simpler than correcting deficiencies . Simply rinse the substrate with water and hope that the plants are not stressed by excess humidity.
In cases of nutrient deficiency , careful inspection of the plants is necessary to determine which nutrients are lacking. To ensure optimal plant nutrition , it is essential to carefully monitor the pH of the substrate. An inappropriate pH can hinder the absorption of all nutrients present in the soil. ( Page 68 of the Guide )
The size of your plants, of capital importance in indoor cultivation ☘
It is crucial to prune your plants regularly to maintain their vitality and minimize the risk of wasting energy , which could hamper their growth and make it unattractive to you as a grower. However , it is important that novice growers do not give in to the temptation to over -prune with their scissors.
Some precautions are necessary:
The main goal of pruning is to direct the plant's energy to areas where it will be most beneficial. For example, you may opt to prune some lower shoots , because your plant's buds will mainly develop at the top of the stem . If several branches already seem to be doing well, you may choose to prune some lower shoots to focus energy on the branches that are already thriving.
Pruning can also be used to remove dry or yellowing leaves . This practice prevents the plant from having to mobilize its resources to save declining leaves. The energy is thus redirected towards the creation of new leaves or the production of flowers. ( in find out more about size on page 73 of the guide )
the Flowering Stage 🌹
the long-awaited moment when the fruits of your efforts begin to emerge. However, keep your enthusiasm in check for now. Vigilance remains essential during this crucial phase, because problems can still arise. It's the final act of plant growth, and the slightest mistake can wipe out your entire harvest.
How to Achieve Flowering
For indoor plants (except autoflowering varieties), you must encourage them to flower by manipulating their light cycle . As mentioned in this guide , plants in the vegetative phase follow an 18/6 day/night cycle, although some opt for 24/0, but this is less common. To initiate flowering, 12 hours of total darkness each day are necessary. All you have to do is switch the light regime to 12/12.
If you haven't yet distinguished your male plants from females, now is the time (unless you plan to pollinate them to create your own seeds). If you're having trouble identifying the sex of your plant, consult the dedicated section in this guide . And if you intend to harvest buds , it is crucial to separate the males from the females . ( in find out more about flowering on page 79 of the guide )
Pest Management 🐛
Although you're less exposed to invaders than outdoor gardeners, that doesn't mean you're safe from all problems. Pests can sneak into your growing space and disrupt the well-being of your plants, making monitoring crucial.
Aphids are among the most common pests in indoor growing , but spider mites and midges can also be a problem. Using pesticides may be necessary , but spraying your precious buds with chemicals is not ideal . This is where prevention comes in, as the preferred method of control.
Before we give you advice on how to combat these invaders, let's look at some ways to prevent their intrusion . It is always wiser to prevent than to cure. For an exhaustive list of the most common parasites in indoor cultivation, consult the chapter on parasites and predators in the section dedicated to growing cannabis outdoors. ( in find out more about parasites on page 81 of the guide )
Optimize the security of your indoor growing space: discretion above all! 🤫
Even in areas where cannabis cultivation is legal, discretion remains a key priority. Although there is interest in the plant, not everyone can start growing it. In addition, there are hostile onlookers who could compromise your efforts.
The first rule to guarantee the safety of your culture is to not share it with anyone!
Only people who share your living space, whether it's your house or apartment, need to know. Although the idea of revealing your new hobby may be exciting, avoid doing so and save the surprise for the harvest.
Maintain noise and odor control
The noise generated by constant fans , especially when it is not very hot outside, can attract attention and arouse suspicion from your neighbors. Remember that you can choose the times of day and night for your growing cycle. Urban areas are often noisy during the middle of the day due to traffic, schools and workplaces. Turn on your fans during the noisiest hours to maintain discretion, an easier task during the flowering phase with only 12 hours of "daylight" in your grow space.
Also consider using carbon filters and positioning your growing space in a part of your house away from your neighbors. For example, if your bedroom is close to or adjacent to your neighbor's, it might be best not to install your equipment there.
Traditional Gardening in Soil vs Hydroponics in Indoor Culture 💦
Traditional soil-based gardening is familiar to most gardeners and provides a rich source of nutrients. However, hydroponic systems offer benefits such as faster growth rates , increased yields , and better control of nutrient supply. Understanding the differences between the two will help you make an informed decision for your indoor garden.
The Ideal Strains for Indoor Growing 🍃
The choice of seed marks the start of a unique horticultural adventure. Some varieties particularly thrive in an indoor environment. Multiple considerations come into play when determining which variety to grow. For example, the size of the plant and the size of the growing space are crucial factors. Should the efficiency be high enough to compensate for the energy cost incurred?
The following five varieties particularly stand out in the demanding context of indoor cultivation:
- Northern Light : this indica feminized or renowned autoflowering , is known for its relaxing power on the muscles and the mind. It provides a feeling of total relaxation while evoking a subtle euphoria, providing support appreciated by many people facing insomnia or pain
- Big Bud: comes in feminized and autoflowering versions. It is distinguished by the abundance of its harvest, surpassing many other varieties available, while maintaining a moderate stature. As an indica, Big Bud offers its users a deep physical relaxation experience, plunging into enveloping relaxation.
- Amnesia: Despite its status as a sativa variety, Amnesia in the feminized variant comes in an incredibly compact form. Its development in height and width is limited, making it the ideal choice for growers with limited interior space .

Don't be surprised if the experience with this strain transports you to forgetting all your worries , but stay vigilant so as not to lose anything along the way!
- White Widow: seed ( feminized ) stands out among the most famous medicinal cannabis varieties. This sativa/indica hybrid, although only reaching a moderate height and flowering at a slightly slower rate, does offer a phenomenal yield. The appeal lies in the dense layer of white trichomes that unfurl on the buds, as well as the splendor of the White Widow flowers.
- Super Skunk: The seed (feminized version) stands out for growing indica-style while sporting the appearance of a sativa. Perfectly suited to indoor growers operating in tight spaces , but who enjoy the characteristic effects of a sativa , Super Skunk proves to be an exceptional choice. Displaying a generous yield , it maintains a moderate stature and ignores temperature rises.
Your floral gems are now ready to be savored and preserved . In an optimal state of freshness, they retain their appetizing quality for years. But don't hesitate to reap the fruits of your labor sooner if you feel like it!
The art of storage is child's play. Follow this golden rule:
- opt exclusively for glass!
Avoid contact with plastic, which can infiltrate its unwanted nuances into the buds, altering the taste when tasting. Additionally, plastic encourages moisture buildup, potentially causing your precious crops to wither over time. As for the paper, it has the unfortunate tendency to absorb all the humidity, accelerating the drying process of the buds. Use it for short-term transport, but for long-term storage, prefer the glass jar.
Concerning drying , do not overload the jar . Give your heads some room to breathe. Keep the jars in a cupboard or cool place out of direct sunlight. Heat and light, enemies of cannabinoids, could compromise their potency over time.
Homemade cannabis products 🍽
Explore beyond just burning or vaporizing cannabis . Transform it into food , into ointment, or immerse yourself in the world of powerful concentrates. However, eating raw buds or applying them to the skin is not enough to reap all the benefits. Cannabis requires specific treatment that you can easily carry out at home with basic kitchen utensils. By reading our free guide on page 151 , discover various options for transforming your buds into edible delights or cannabis tinctures.
