The basics to know about a Grow Box

Gardening at home, or starting an indoor cultivation, requires a minimum of space and installation beforehand. And the most common is to install a grow room. Let's find out together what this is all about and how to go about it.

The basics to know about a Grow Box

What is a "box"?

In indoor growing, a box is a tent or growing room that allows you to reproduce the weather conditions outside, for example, you can grow your own tomatoes, herbs or orchids.
You can place it in your home, in a room, in the basement or in your garage, where the temperature remains constant.

What is it made of?

A grow room is made of canvas (reinforced or not), held together by metal bars joined by plastic or metal fittings. Usually equipped with one or more reclosable doors with zippers, it is generally black, airtight and waterproof. The purpose of this is to recreate in your home the external conditions close to nature.
Thus designed, it allows you to establish and control a certain climate without disturbance from the outside (you are the master of the seasons):

  • light thanks tohorticultural lamps
  • air by goodventilation
  • temperature and humidity usingclimate control
  • protection against undesirable insects throughinsect treatments

Its internal material, made of mylar or a simple white tarp, reflects the light from your horticultural bulbs (amplified by reflectors). This coating also promotes appreciable heat conservation for plants.
In addition, depending on the brand or model, the hydroculture tent is equipped with small windows, holes or socks (a kind of "hole pocket"): these are passages for cables and connections, as well as for air extraction/intraction and to facilitate the passage of ventilation ducts.

Of course, by investing a little more, you can find more resistant models that offer other options as well:

  • larger dimensions,
  • storage pockets,
  • suspension straps for attaching a lamp,
  • of the side doors,
  • ventilation grilles,
  • of the floors,
  • separations to have 2 tents in 1, or more,

Another alternative is to have a "hard room" to grow your indoor garden. This involves directly investing one of your rooms and/or placing solid partitions in it. A solution to the soundproofing problem and the inconvenience caused to your neighbours or your own comfort. Indeed, a fabric is less effective against noise pollution than, for example, a ventilation system (noise ofextractors) or lighting (noise of the ballast). Also, during the flowering phase, the plants may smell more or less strong. Think about equipping yourself for odour treatment (with a carbon filter, for example).

How do you know where to place and furnish your stall?

It all depends on the type of indoor garden you want to create and how much space you have at home. Because you have to take into account that a tent has a certain basic volume, even the smallest one. Your growing space must therefore be thought out in advance.
The minimum height required for a growing room is about 1.40 m. Please note that, because of the pots, the plants are at least 30 cm above the ground. And that the lighting must be suspended at a distance of about 30 cm from the roof of your tent. Add to this the plant-lighting distance.

A tent can have several sizes, to be chosen according to your needs. The most comfortable height is 2m, which gives you enough room to not limit yourself. Because you have to think about the development of your plants. And yes, because a garden of shoots or mother plants during the growing phase takes up less space than during the flowering phase.

That's why, for a permanent culture, it is recommended to have one space for growth and another dedicated to flowering. To do so, some solutions:

  • one of them is to divide the growing area in two, if the space in the stall allows it. Moving the pots from a growing to a flowering arrangement requires more space, practice and investment. This installation can be done as you go along, but it is a good idea to prepare for it at the beginning of your cultivation.
  • Another requires even more space and experience: a growing room and a flowering room. For good results, two different climates will have to be managed simultaneously.
  • Or, as mentioned above, the Grow-Tent Dual Silver 2 in 1 with a growing space below a larger room for flowering. It is also possible to have more compartments in a tent: we have an example of this with Secret Jardin's Lodge type.

What can there be in a box?

Example of a growing tent dedicated to growth
(where it is possible to put germinations, cuttings, and/or mother plants):


  • temperature: between 20°C and 25°C during the day - around 18°C at night
  • hygrometry rate: between 50% and 70%
  • lighting: cold/blue light under reflector (glass, ventilated, or cooltube), with for example a 110W double fluo-compact lamp, MH, neon, Ecolight, or LEDs

Example of a growing tent dedicated to flowering :

  • temperature: between 25°C and 27°C during the day - around 18°C at night
  • hygrometry rate: between 40% and 60%
  • lighting: warm/red light under reflector (glazed, ventilated or cooltube), with for example a HPS 400W lamp or LEDs
  • climate: extractors, fans, charcoal filter...
