Before you start setting up your grow space you should decide on the number and type of plants you are about to cultivate. If you want to grow large plants, plan that you can store about 4 plants in one square meter.  With average size plants you can plan to double the number in one square meter, therefore you can have 8 moderately sized plants or 16-20 small plants. This will dictate the size of the growing space and the type and amount of lights you should be using.  

Choosing quality soil is very important, therefore you should consider buying it from a brand that sells cannabis-friendly soil only. However, here we’ll list some of the signs that tell if the soil is good for cannabis:

  •   It is very dark
  •   Loose in texture
  •   Holds the water and it doesn’t get muddy
  •   The water easily drains to the bottom

A closet or wardrobe that is light-proof and set up in a dark and dry place can be suitable. However, it is recommended to use an indoor grow tent. You can find many different types of tents on the market and whatever your choice is you can rest assure you have a perfect space to begin growing.

Both lights and ventilation fans can be included in all-in-one kit boxes with a grow tent. However, custom design space is better for optimal results.

Ventilation is important in order to keep the plants fresh with the moving air and make them feel like home (nature). You need two types of ventilation fans – one that ventilates the air inside keeping a good temperature and controlling the humidity and other that is designed to pump the hot air out.

Ventilation is prevention for molds, mildews, spider mites and other pathogenic infections that can seriously damage your plants. It also helps in regulating the heat which is very important. 

If you are growing in a wardrobe or closet you can make holes in upper corners to install the fans. Some people choose to leave the door slightly open. However, it is advisable to choose a good combination of fans and place them according to the manufacturer’s guidelines to be sure of the proper ventilating effect. 

Regulating the Temperature and Humidity

These two factors have a great impact on the plants, thus you need to find a way to constantly control them. You can do this by installing some measuring instruments inside the grow space – thermometer and humidistat are a must. 

The temperature and humidity depend greatly on the climate in your region. Therefore you can assume what would be your pros and cons. When it comes to temperature the ideal range for growing cannabis is between 65 and 80°F or 18 – 26°C. As for humidity, the advice is to be kept between 30 and 50 percent.
