Beginners Guide Growing Cannabis Indoors:
Before you begin an growing cannabis indoors you will need the following:
Tools to monitor your grow environment
- LED Glow Light Timer
- PH Testing Kit
- Temperature and Humidity Sensor
- Intake Fan placed at the bottom
- Exhaust placed at the top
There are 2 different types of nutrients your plants need, macro and micro. The main ones are macro: N -nitrogen, P- phosphorus, and K- potassium. Nitrogen will help improve leaf growth, and potassium improves bud production. Read about the best nutrients for growing cannabis here.

Beginners Guide Growing Cannabis Indoors
Best Grow Tent for beginners?
To grow Cannabis at home you should prepare a space that is easy to control factors like humidity, temperature and light . The simplest would be to use as little space as possible for your cannabis plantation to save on energy costs with specialized lights. For example, the Grow Tent on the side carries from 10 to 12 plants and comes with Removable Floor Tray 48″x24″x60″ Grow Kit Mylar Ventilation Box Vegetable Seedling Sprout for Carbon Filter Exhaust Fan. This is a great Grow Tent for beginners and has great reviews.
Choosing the right seeds, how big does a marijuana grow
As you will plant indoors, choose seeds that are adapted for indoor planting.
Usually this is always indicated on websites that sell seeds, but you can get an idea of the size by looking at the genetics of the plant.
Usually the plants with the highest percentage of Indica are more robust and smaller.
An Indoor cannabis plant usually grows around 1.5m.
However in outdoor this same plant can grow 3 meters in height!
Best Soil for Growing Cannabis
As this is a guide for beginners, I’d recommend buying Organic Potting Mix.
The quality of the soil is essential to get a good result in your marijuana planting.
This is what kind of soil to get if you don’t have any “good” soil available, but want something that is known to work for growing cannabis.
Generally, anything labeled as an “organic potting mix” will work. This type of mix doesn’t have chemical slow-release nutrients, which is a major thing to avoid when growing cannabis. I would recommend the “Black Gold All Organic Potting Soil” which works really good, because it doesn’t contain these chemical nutrients and it has good drainage. Your plants will be happier if you select the best soil.
Usually an organic potting mix does not have enough nutrients to last your plants for more than a few weeks, so it’s a good idea to always supplement with cannabis-friendly nutrients, especially in the flowering stage when your plant is making buds and needs lots of extra Phosphorus and Potassium.
Size of Pot For Indoor Plantation
Usually three pot sizes are used for each phase of the planting. Germination (less than 1L), Growth until finding the sex of the plant (5-10L) and final growth until the end of flowering (20-40L)
In the germination stage, you can plant many seeds in a large pot (distance 5-10cm) or in several pots less than 1 liter for example until the first stage of growth.
Marijuana bud, first stage of growth.
However in the second stage of growth it is recommended to plant in pots of 5 to 10 liters.
Be careful when transplanting the small, fragile cannabis shoot into the second pot. For this use a tablespoon can help.
Once you can identify the sex of the plant transplant into the a 20 to 40 liters pot.
Tip: The larger the pot the more your plant has a chance to grow healthy. Be careful of small pots, they greatly influence the size of the buds!
When transplanting to the final pot (minimum 20 liters) add about 40% perlite in the bottom, for air circulation and drainage
When your cannabis plant reaches the 5th stage of growth, that is between 6 and 8 weeks after the first phase. The first pistils of the female plants are already seen all over the plant and it already has 5-8 layers of branches.
Ideally, in any planting that is indoor or outdoor, we can see if the plant received sufficient light by observing the distance between the nodes at the end of the growth phase. In this step, the shorter the space between each branch the better.
When your plant is ready for the flowering process to begin, the light cycle is changed to a regimen of 12 hour on and 12 hours off. The increasing hours of uninterrupted darkness helps the plants to respond as if was almost Autumn, and begin to flower. By using these two light cycles, you can control when your plants flower.

Types of lighting for indoor cannabis planting
There are three main types of specialized lighting for indoor planting and more specifically for marijuana. The lamps HPS, CFL and LED. In this guide we will briefly go over the characteristics and appropriate uses of each.
HPS (sodium) lamps are the most efficient and undoubtedly the most used. But they can produce a lot of heat in enclosed spaces and consume a lot of energy. I wouldn’t recommend this type of lighting for a beginner.
CFL lamps do not heat very well and are therefore used in small spaces such as Grow Tent or Grow Box of 4 plants for example. They are similar to the economic ones sold in the supermarket, but much more powerful. The only disadvantage is that they tend to yield less than HPS.
LED Grow Lights are no longer new in the indoor growing market. There are already many lines that present surprising results in the collection and greater energy savings than the CFL. The only problem is that, although they have a longevity far greater than any type of lamp on the market, LED is still very costly, with that said I’d still highly recommend choosing LED Grow Lights.
Fluorescent tubes are mainly used until the second stage of growth and in the production of seedlings.
TEMPERATURE, IDEAL HUMIDITY, VENTING AND FILTERING OF ODORS
To plant cannabis indoors, you will want to keep the temperature between 18 ° C at night and 30 ° C at day. The marijuana plant likes a relative humidity of about 60-70% in the vegetative growth phase and 40-60% in flowering.
The ideal temperature and humidity in an indoor planting are mainly controlled by ventilation, the time of day to switch on the lighting and the proximity of the lights to the plant. If you live in a very hot place, leave to turn on the lights at midnight for example.
Good ventilation is crucial for the development of your ganja plants. The grow tent you use should have at least one air extractor at the top, and a fan to make air movement and “work the plant”
