Indoor culture: how to grow cannabis indoors?

Cannabis is an annual plant of the botanical genus belonging to the family of Cannabaceae.

It is native to South Asia, like all plants of this family. Cannabis therefore needs a warm climate in order to be grown, between 20 and 30°C depending on the period, and needs fairly substantial, but decreasing humidity: during the growth period, we turn around 65%, 60 to 40% during the vegetation and flowering period, and 40 to 30% at the end of flowering.

It is therefore a difficult plant to grow in Europe, because it requires indoor growing equipment in order to keep it in conditions similar to those of its original environment, as well as very specific care.

Cannabis use

Let’s forget about mind-altering use for a moment. Cannabis is a plant that was widely used in Asia, already in the Neolithic period. The fiber of this type of plant was already used in 600 BC in China, but also in Europe during the Middle Ages, in order to create all types of clothing, in particular by mixing linen with this fiber.

Indeed, it is cannabis fiber is extremely resistant and was also used to make ropes, thermal and sound insulation, and even paper at the time.

In terms of legislation, what does French law say?

You probably already know it, but the possession, transport, sale and cultivation of cannabis, but also its consumption, are prohibited in France and the penalties incurred are quite significant: you incur a fine of 200 euros to be paid immediately in the event of possession of cannabis in small quantities or consumption. But that’s not all, because you can also be seized in criminal justice, or you incur one year in prison and a fine of 3750 euros in this case.

Note also that organized drug trafficking, whatever it may be, exposes its practitioners to a sentence of 10 to 30 years in prison as well as a fine of up to 7,500,000 euros.

On the practical side, what equipment is needed to grow cannabis?

If you still want to take the risk of indoor cannabis cultivation, despite what has been said about the illegal side of this cultivation and the penalties incurred, then here is the necessary material, in addition to seeds, soil and pots, of course sure :

  • Greenhouses, rooms or indoor growing cabinets
  • Horticultural LEDs, growth and flowering lamps, specific UV lamps
  • Ventilation system
  • Climatic and thermal control
  • Ventilation ducts
  • grow guide

The indoor cultivation of cannabis is done like any other type of plant that can also grow indoors, whether it is flowers, shrubs or even vegetables and aromatic herbs, except that it is imperative set up a culture chamber.

The first step is to choose the type of plant you want to grow, and this varies according to your desires. Online sales sites as well as online botanical glossaries generally explain the differences and uses between varieties.

Then comes the time to install your growing space. Here, there are two schools: home-made growing spaces, with tarpaulins, lamps and heaters, or “pro” growing spaces that are sold in specialized stores.

Of course, the second solution is the safest way to grow cannabis plants without encountering problems. You can either buy everything independently, or buy beginner kits containing several accessories as well as culture chambers, depending on the site.

Once you have installed your grow room, as well as ventilation, heating and humidity control or assembled your growing cabinet as a kit, then it is time to start sowing seeds. To do this, buy seed pots, simply fill them with normal soil if you have chosen an easy-to-grow species, or follow the advice of your seller if the variety chosen is a little more special, then plant the seed. .

You will then need to be patient and keep the soil moist, but not flooded, until the seed germinates. Once the first leaves appear, repot in a larger pot. After this repotting, water the plant moderately and watch its growth, until the plant has reached maturity, at which time you will move on to a second and final repotting.

After the latter, only one thing to do: continue to water the plant when it really needs it and keep the temperature and humidity constant and adequate.

And the price then?

The price depends on the type of room chosen, the type of seed, the number of plants, the electricity consumed, etc.

Let’s say that by taking a culture chamber of 100 x 100 x 200 cm, you are already at more than 100 euros, the necessary lamps are between 75 and 300 euros depending on the type of these as well as their size, a A good temperature and humidity controller costs at least 50 euros, and the ventilation ducts (without the system) cost around 10 to 20 euros for two, if you take plastic and aluminum ducts.

It is therefore necessary to count a minimum of 300 euros, without the ventilation system, the pots, the soil and the seeds, in order to be able to start a culture. To this will be added, of course, the price of the electricity consumed. Given the costs involved, think carefully about what you want to buy and do before making any purchase.
