How to Grow Cannabis Indoors

Growing cannabis indoors with cannabis seeds from SuzySeeds gives you the opportunity to grow those strains that are less effective outdoors. Cannabis strains with a long flowering period and strains that are sensitive to temperature fluctuations and high humidity. By imitating the ideal climate in an indoor space, the plants come into their own better. An indoor grow room doesn't have to be high-tech, as long as it's safe and doesn't cause a nuisance to other people. But the attention you pay to your grow space and grow equipment is reflected in the end product. And a good end product starts with good seeds.

Pros and cons of growing cannabis indoors

Growing cannabis indoors from seed has advantages but sometimes also comes with disadvantages. These depend on the space and location that you have at your disposal.

Advantages of growing cannabis seeds indoor: 

  • One of the advantages of growing indoors is that you can grow clean cannabis. By keeping your grow room (and the space around it) clean and well-conditioned, you keep it and the plant free from pests, fungi and diseases.
  • With an indoor cultivation you have the opportunity to constantly create an ideal climate for the plant. You regulate and control everything yourself, from growth phase to flowering phase.
  • Due to a short growth phase, you can grow several rounds in one year with an indoor grow. This also allows you to grow multiple varieties and always have a stock of fresh home-grown cannabis.
  • You can grow varieties indoors that you can hardly grow outdoors, if at all. Cannabis strains with a long flowering period, such as sativa strains, can be left to full bloom indoors.

Disadvantages of growing cannabis indoors:

  • Improperly constructed grow installations are dangerous! Some technical knowledge is not superfluous here. Therefore, be well informed when purchasing your equipment. There are also more and more fully equipped and coordinated grow tents available with approved equipment such as lamps and extractors.
  • The purchase costs are high. It is quite an investment to set up a proper grow room. As growing marijuana for personal use becomes more popular, more and more cheaper grow products that are unsatisfactory or even dangerous are coming onto the market.
  • An indoor grow must be closely monitored. Light, air, water and food. All factors must be given at the right time and in the right amount.

Three important factors

You add water and nutrition to the soil. Temperature and humidity determine the air. And sun is the light of your grow light. So soil, air and light are the three important factors in indoor growing.

Soil

Soil is potting soil and the medium in which the plant grows its roots. Although there are several mediums for growing plants such as coconut, clay granules or rock wool, soil is by far the best known and gives the best results. There are various brands of potting soil on the market that are specially tailored to growing cannabis. Clean soil with the capacity to retain water well and with the right nutrition ensures healthy soil life. Every food is based on nitrogen, phosphorus and potassium (N-P-K). Check the acidity (PH) of the medium and the feed water. EC is a term that you often hear. This is the electrical conductivity that determines how much food should be administered. This is especially important in hydro-culturing. Nutrient intakes for a cannabis plant on Earth are best done between PH 6 - 6.5. Preferably give organic food. There are complete food lines on the market that regulate the PH themselves. Healthy soil life promotes root growth and plant health. So give them space and grow in spacious pots.

Suzy's Tip: Never use soil from outside for indoor cultivation. You run the risk of bringing in harmful parasites, insects and diseases.

Light

There are many lighting sources that can be used when growing weed. HPS, CMH and LED are the most common.

  • HPS lamp, High Pressure Sodium lamp, is the lamp on which most indoor weed is grown. This lamp has proven its worth for years. Available in 250, 400, 600 and 1000 watts. A disadvantage of these lamps is that they become very hot and, if installed incorrectly, can even pose a fire hazard because they are filled with gas. After three to four breeding rounds, the lamp needs to be replaced.
  • CMH lamp, Ceramic Halide lamp. The amount of light emitted by a lamp is indicated in Lumens. The CMH lamp is still a gas-filled lamp, but with a lumen output of almost twice as much as an HPS lamp with the same wattage. To light a CMH or HPS, you need ballasts to start the lamps.
  • LED lamp, Light Emitting Diode LED lamps have been on the rise in recent years. The techniques are getting better and better and nowadays achieve the same results as an HPS or CMH lamp. They are cheap, safe to use and have a long service life. They produce much less heat and do not require a separate ballast. The amount of the purchase price is what often prevents the grower.

Once a lamp has been selected, take into account the distance from the lamp to the plant. If the lamp is hung too high, there is a loss of light. If it hangs too low, there is a risk of damage to the plant due to the heat and bright light. It is recommended to use a dimmer for young plants. Keep your grow room light-tight! Make sure no light shines outside, this way you keep your grow space hidden. But it is also important that no light enters and disturbs the night's sleep of the blooming ladies, resulting in stress.

Growing your own cannabis Air

Depending on the heat emission of the lighting and the environment of the growing area, it is important to create an ideal temperature and humidity in the room. Fresh air is drawn in from below. The warm air is discharged from the top by an exhaust fan in the exhaust. By controlling the extraction quantity, you can regulate the temperature and humidity. Sometimes it can be useful to use an air conditioning system. Make sure that the air drawn in is clean and that no insects can enter through the inlet. Always place a carbon filter on the exhaust side to remove the air without odor. This way you prevent nuisance and thunder. A fan in the grow room is necessary to simulate a breeze. A small wind makes the plants strong and ensures good airflow. With a combined temperature meter-hygrometer you can check the temperature and humidity in the room.

Suzy’s Tip: Replace the carbon filter after three to four cultivation rounds to prevent odor nuisance
