Cultivating Cannabis Indoors for the First Time? Follow These Tips

If you’re a seasoned stoner willing to cultivate your own cannabis, then you can always set up your own grow room by following this DIY. However, you could feel that you’re completely lost if you do not have any idea where to start or how to even begin in the first place. As a first-time grower, it’s perfectly normal to feel utterly bewildered or confused when it comes to growing marijuana in your backyard.

If you go through this beginner’s guide for setting up a grow room for cannabis, and follow the cultivating tips, you could be well on your way to reaping your first crop in just 2-1/2 months. Before you begin, you’ll need the following:

Getting started

Grow tent or any other ready space

By opting for a grow room or grow tent, you’ll be spared the hassle of turning your cellar into a greenhouse that could be laborious and time-consuming. Grow tents are available in a wide array of sizes, choose one as per your needs and preference. Always go for a product that has a reflective inner surface for thorough reflection of light from lighting equipment. This type of grow room also tends to be thicker, helping in screening out external light.

Starting with the basics: sourcing the seeds

Next, you’ll need seeds from which the saplings will sprout. Make sure you source the seeds from professional breeders who possess a valid trading license. Also, ensure that you order only those seeds that’ll develop into female plants-look for the tiger-stripe outline on them.

Peat pellets to expedite germination

You’ll definitely need peat pellets to expedite seed germination. Immerse them in water so that they enlarge, and after that, position the seeds about ½” deep. Water the pellets gently so that the seeds stay intact inside. The seeds should start sprouting in 4-7 days.

Taking advantage of grow lights with timer

After the seeds sprout, switch on the grow lights. Make sure that from the time the saplings are about 3 weeks old, they receive at least 18 hours of illumination every day. The saplings will rest for the remaining 6 hours when the lights will be off.

Once they’re about 3-1/2 to 4 weeks old, they’ll remain in light and darkness 12 hours consecutively for accelerating the flowering cycle. Using LED grow lights are recommended as this type of lighting will enable you to save on utility bills both for illumination and ventilation. Choose a premium quality programmable timer that’ll automatically switch on/off the lights as per your requirements.

Promoting healthy circulation of air

No matter whatever type of grow light you use, LED, MH (metal halides) or HPS (high-pressure sodium), a specific amount of heat will be generated. Though the plants will need heat up to an extent, excessive heat could scorch them. You could dissipate the accumulated heat through a duct fan or carbon filter. Using a heavy-duty duct fan will also help in driving away the odors.

Growing marijuana in plant pots

Gradually, the roots will be protruding out of the pellet edges. Once you spot the roots pushing outwards, take the sapling along with the pellet and tuck it deep inside the small pot of 1-2 gallon size. Transfer the seedlings to large size pots so that they can easily grow into fully mature plants.

You can use plastic pots provided they’re well constructed, but fabric pots are the most heavily used products. Make sure you place trays underneath the pots to prevent overflowing of water.

Soil and nutrients

Only use organic soil if you wish to get the best results, i.e., heavy yields. Buy soil bags that can be easily inserted inside the pots. When it comes to feeding the saplings and plants, steer clear of chemical-based fertilizers.

Go for basic organic nutrients, including nitrogen, phosphate, and potash in a ratio of 7%: 5%: 6% respectively.


As for watering the plants, the saplings need water once weekly, and mature plants need to be watered at least once daily. Better to water them with filter water rather than tap water. Just plug a filter on the mouth of the faucet for a running supply of filtered water. Choose a watering can that comes with an elongated spout. The appearance of the leaves and the temperature of the soil will let you know when you need to water the plants.

Checking moisture content of the soil

You can use a hygrometer or a moisture sensor thermometer for monitoring the soil’s moisture level. Using any of the above two devices will spare you from the trouble of having to depend on guesswork.

Containing the odor

You can take it for granted that the grow room will become odorous once the plants start flowering and the stalks become laden with trichomes. The intensity of the odor will obviously depend upon the variant or breed of cannabis you’re growing. A ventilation system will definitely help in containing the smell to a great extent but getting hold of a charcoal or carbon filter and enveloping the ductwork with the same will keep snooping neighbors away.

Harvesting the crop

You’ll be so busy tending to the plants that you’ll not be able to keep track of time. The buds should fully ripen at the end of 3 months if you’ve strictly followed all the breeding guidelines. How can you tell when the colas and trichomes mature? The whitish strands of hair will start to take on a brownish hue-this is the most detectable marker.

Take extra precaution while trimming the leaves and the buds. Use flexible garden clippers or shears from Black & Decker.

Processing the buds

Your buds are ready to be put in a vaporizer soon after picking. The best way to cure them is to dry them up and put inside a jar. The buds will reach their full potential in about two months, enabling you to enjoy an intoxicating high every time you toke. Place the buds in ball jars with a broad opening for curing them correctly. Replace the caps tightly to make the inside of the glass jar thoroughly airtight.
