Growing Cannabis Plants Indoor: Guide for Beginners

Growing cannabis indoors is no longer difficult today. The market is now full of strains bred to grow successfully indoors. People are calling them the best indoor cannabis seeds.

These strains thrive well indoors and respond well to different growing methods. If you’ve never cultivated weed indoors before, then it’s time for you to get started. Please read on and know these simple recommendations that can help you make your first attempt a success. 

Where Should You Grow Cannabis Indoors?

One of the simplest ways to start here is to grow your plants in a purpose-built indoor grow tent that is widely available today online from various sellers. It is a sturdy tent that you can easily assemble and use after a few minutes. It is also lightproof. It comes with the needed holes for air extraction and cables.  An indoor grow tent costs around $100 to $500 for the basic model.

Should You Grow Your Plants Hydroponically or in Soil?

Weed can grow successfully in many ways. Maybe, the easiest method to grow cannabis indoors is to do it in soil. However, cannabis can also grow well when you use clay pebbles, coco fiber, rockwool, and other hydroponic systems without soil. 

Whatever growing medium you choose, the key to success in growing cannabis indoors is to help the roots get the oxygen and nutrients they need. 

Soil for Simplicity

Growing cannabis in a hydroponic system can offer excellent results. However, the extra technical aspects involved such as the pH level and electrical conductivity can be a little confusing for first-time cannabis growers. Since you are new to cannabis cultivation, it is best for you to get started by using soil instead of any hydroponic system. 

The Quality of the Soil

The easiest way to begin growing cannabis indoors is to buy a ready-to-use soil for cannabis cultivation. This product comes from various companies, so feel free to choose a brand but make sure you go for a reputable one. 

That is not the cheapest way to get started but is the simplest because everything has been done for your convenience. Also, you are more certain of the result. 

In growing cannabis indoors by using soil, you can also use something like soil additives that can help maximize the yields. If you prefer compost, add 30% perlite that promotes root aeration. If possible, add worm castings or light soil enhancers like bat guano. Also, make sure you plant the best indoor cannabis seeds by using big pot containers. You can use at least 4 to 5 gallons.

You have nothing to worry regarding nutrient deficiencies and bad pH levels. Your number one concern here is to water your plants lightly twice every week. Perhaps you can add some liquid feed at the end of the flowering stage if the nutrients in the soil are getting worn-out. 

Be sure not to overwater and overfeed your cannabis plants as they can cause stunted growth and decreased yield. In worse cases, these common issues lead cannabis plants to death. 


Make sure also that your grow room maintains the right temperature. The ideal temperature for growing cannabis indoors is around 77 degrees Fahrenheit. If the temperature goes more than 86 degrees Fahrenheit or less than 68 degrees Fahrenheit, your plants will start to grow slowly. It can even lead to other issues.


If you grow cannabis in a tent, you must release the air from it. You can use a special type of fan that can absorb the air through the tubes that are typically 4” in diameter. The air must pass through the carbon filter which will remove the traces of natural weed odor. 

The extracted air is typically vented outdoors or in a well-ventilated attic. Experienced cannabis growers are using ozone generators in removing even the slightest, lingering smell of cannabis.  You can visit and get more help at homegrown cannabis Co.

If you’re growing cannabis indoors, you should use carbon filters. Marijuana plants require a consistent supply of clean and fresh air to keep the plants healthy and thrive successfully. 

Choosing a Strain

You’ll get two choices here. You can either grow auto seeds or just settle for the regular photoperiod seeds. The autoflowering seeds will take 7 weeks to sprout and grow into mature, high-yield plants. These seeds grow under a 20/4 light cycle, which means 20 hours of light and 4 hours of darkness. 

Traditional strains often grow under 18 hours of life and 6 hours of darkness. This setup is ideal for the vegetative phase in which your plants grow roots, leaves, and branches without buds. 

Usually, most cannabis growers change the light cycle into 12 hours of light and 12 hours of darkness after 4 to 5 weeks. It causes the marijuana plant to go and reach the flowering phase and produce those THC-rich buds. 

Generally, the flowering time for cannabis plants takes 8 to 12 weeks, except for the auto seeds that often take 6 to 7 weeks to flower. It may also depend on the strain. 

When the buds are ready to harvest, growers cut the mature plant, and trim and dry buds in a few days. They often cure the buds in a glass jar for one to two months that will make them more flavorful. 

Marijuana plants can be male and female but only the female plants can produce buds. When buying cannabis seeds for indoor growing, look for feminized seeds to be sure that all your seeds will grow into female plants. 

Novice growers like you should be more careful when buying cannabis seeds. Make sure they originate from a reliable seed company.

According to there are many good seed companies out there. The best thing to do is look for those established companies that have good customer reviews to be sure of the seeds’ quality.
