how to grow weed indoors steps

You’ll likely yield about the same amount of weed in both cases, but more harvests mean you’ll have fresh weed to smoke more often and have more opportunities to grow different strains. But more harvests also means more work in cleaning up the space between harvests, trimming, etc.

Controlling temperature in your indoor grow room or cannabis garden can be achieved by manipulating these factors:

The two factors you need to control to dial in the environment are temperature and humidity.

Remember, a common mistake newbie growers make is to overwater plants.

That’s a big variance, but it really depends on how big you want your plants and how often you want to harvest—you can have multiple harvests of smaller plants, or less harvests of bigger plants.

Daily maintenance checklist for your indoor marijuana grow.

The flowering stage will always take about eight weeks—some strains take seven, some nine, some even more, it depends on the strain.

Inexpensive options include standard plastic pots or cloth bags, while some growers choose to spend more on “smart pots” or “air pots”—containers designed to enhance airflow to the plant’s root zone.

Think of all the equipment in your grow space as organs in the body—if one fails, the others will have to work a lot harder for a bit, and then will fail in a matter of time.

Terra cotta pots offer a unique set of benefits to growers in hot climates.

The first step in odor control is making sure temperature and humidity are under control in your grow space—high temperature and humidity will perpetuate odors.

Fans should be positioned to provide direct, even airflow throughout the garden. This typically involves using multiple fans that work together or fans that have oscillation capabilities.

When growing weed indoors, you’ll likely have to add nutrients to your plants. You won’t need to add nutrients every time you water, but get on a schedule where you water every other time, or two on, one off.

As your plants get bigger and especially when they start flowering, they’ll start to smell more. Outfitting your grow with a dehuey or AC can help bring odor down.

You will definitely want to invest in a timer for your lights. Because the amount of light a plant receives dictates its vegetative or flowering stage, it’s important to give it a consistent amount of light every day, and that’s done with a timer. It’s a good idea to check your timer at least once a week to make sure it’s working properly.

Many growers will start plants in a one-gallon pot and then transplant up to a bigger pot as plants get bigger. A lot of growers will transplant once, from a one-gallon to a five-gallon pot, and harvest from there. If your plants get bigger, they may need a seven- or ten-gallon pot.

Regulating Humidity.

The biggest variability in how long a marijuana plant takes to grow will happen in the vegetative stage—after the seedling phase and before flower.

But the benefits are great: LEDs last much longer, use far less electricity, create less heat, and the best designs generate a fuller spectrum of light, which can get bigger yields and better quality.

You’ll need a dedicated space for your marijuana plants—you won’t be able to move them around. Ideally, the space is next to a window so you can vent air from the grow space outside. Growing weed plants smell! Especially when flowering kicks in, you’ll want to redirect air so your house doesn’t reek of weed.

Plants need 18 hours of light a day when in the vegetative stage and 12 hours a day when flowering. The reduction in light from 18 to 12 hours a day is what triggers the flowering cycle—when weed plants start to grow buds.

For growers who have a little extra money to spend and want full control over their indoor garden, environmental controllers will allow you to automate the process. These devices are essential for if you’re away from the garden for a long period of time.

For the most part, weed prefers these temps at each growth stage for optimal health:

If you can’t afford both MH and HPS bulbs, start with HPS as they deliver more light per watt. Magnetic ballasts are cheaper than digital ballasts, but run hotter, are less efficient, and harder on your bulbs. Digital ballasts are generally a better option, but are more expensive. Beware of cheap digital ballasts, as they are often not well shielded and can create electromagnetic interference that will affect radio and WiFi signals.

Tools to measure temperature and humidity.

Proper air circulation will help maintain temperature and humidity, and also bring down odor. Ideally, air needs to move through a garden every few minutes, and you should create a vent to the outside. Oscillating fans, and intake and exhaust fans can move air through your garden quickly, taking odors out with them.

While shopping for soil, you might be overwhelmed by the options available at your local garden store. The soil type is the basic structure of your soil. From there, look at nutrients, microorganisms, and other amendments that improve the soil. Your choices will be flooded with words like:

You can connect a controller to fans, dehumidifiers, humidifiers, heaters, or air conditioners, and set thresholds whereby each device will power on and off based on your ideal environmental settings. Some units run autonomously, making changes based on set parameters, while others allow you to control each element via an app on a phone, tablet, or computer.

These come in different shapes and sizes and are a great way to get rid of odor in an indoor weed grow. Also known as “carbon scrubbers” for their ability to get contaminants out of the air, these employ activated and highly ionized carbon to attract particulates responsible for carrying odor, such as dust, hair, mold spores, and volatile organic compounds, and traps them in a filter.

As much fun as growing marijuana indoors is, having a home that perpetually smells like fresh weed can be a serious inconvenience, if not to you than possibly your neighbors. Although weed odor from a small indoor grow in a closet is much easier to manage than a large grow with several flowering plants, both can produce pesky odors that will permeate an entire home if left unattended.

Unless you’re growing in a large, open space with a lot of ventilation, you’ll need air-cooled reflector hoods to mount your lamps in, as HID bulbs produce a lot of heat. This requires ducting and exhaust fans, which will increase your initial cost but make controlling temperature in your grow room much easier.

What type of container you use will depend on the grow medium, the system, and the size of your plants.

Fans are a must in a grow space to move air around, so buy some of those before an AC unit. If you find that fans aren’t bringing down the temperature enough, then you may want to invest in an AC.

Growing cannabis at home can be a fun project and a nice way to have your own cannabis plants on hand. You may want to grow cannabis indoors due to inclement weather in your area or due to a lack of green space in your yard. Start by germinating the seeds. Then, plant the seeds in soil or in a starter cube. Once the seeds have been planted, care for them properly so they grow and thrive.

To plant cannabis seeds indoors, first soak the seeds in lukewarm tap water for 12 hours. Discard any seeds that float to the top. Then, place the seeds on a damp paper towel on a plate with 1 inch (2.5 cm) of space between each seed. Cover the seeds with another damp paper towel. Keep the seeds in a spot that remains between 70-80°F (21-27°C), and spray the paper towels with water whenever they start to dry out. The seeds will sprout in 2-3 days. When they do, fill pots or a growing tray 3/4 of the way with loose potting soil that has a pH between 5.8 and 6.3. Press the soil down lightly, leaving some air in it. Then, use a pencil to poke 1 inch (2.5 cm) holes in the soil. Place the sprouted seeds vertically in the holes and fill the holes with potting soil. Water the soil thoroughly and place the pots or tray in a spot that’s always 75°F (24°C) or warmer. Set up a grow light over the seeds and leave it on at all times. Water the seeds every day so the soil doesn’t dry out. The seedlings will emerge in 2-4 weeks. To learn how to use cool white grow lights to help your cannabis seeds grow, keep reading!

If you have limited soil options, choose an organic potting mix which is usually available in some form in the gardening section of any big-box store. As long as you use good cannabis nutrients (more on that below), a regular organic potting mix will work just fine.

Are you ready to start growing?

Pick up a bag of perlite (found in the garden section) to help the soil drain better unless it already contains perlite. Perlite looks like little white rocks and should be mixed in so you have about 70% soil and 30% perlite. Should you add perlite to your soil?

Indoor grows tend to be shorter than outdoor grows since you have more control over when the plant starts budding. Auto-flowering grows also tend to be very short. But with shorter grows, you also tend to get smaller yields. Certain strains and certain outdoor grows can take up to 7 months or more.

Step 5: Get Your Cannabis Plants (& Choose Your Strain)

When growing cannabis indoors or outdoors, you will need to ensure that it gets the proper amount of these 6 resources.

Surprising Fact: No one in the US has ever gone to jail or prison for simply ordering cannabis seeds online from overseas.

FOR SERIOUS GROWERS ONLY.

These are the most common grow mediums:

If you’re feeding your plant with additional nutrients, start at half strength as it can be easy to burn your young cannabis plants. Bring to 3/4 strength one plant starts growing vigorously and if your plant displays signs of needing more nutrients even though the pH is in a good range.

I sometimes get asked how to harvest weed… (i.e. cut it down from the plant)

Paper Towel Method:

It’s actually really easy, quick, and cheap to learn how to check and adjust the pH of your water, and there are “pH test kits” specifically made for this purpose.

In order to thrive and grow, every cannabis plant needs:

Step 4: Choose Your Nutrients.

Compact Fluorescent Light Bulbs (CFLs) & household LEDs are what people commonly use to light up their homes. They aren’t really made for growing plants, but can be a good way to get your feet wet in the growing world without a significant investment. They lack the power of dedicated grow lights, but can get the job done. CFLs and home LEDs like these are dirt cheap, and you can usually buy them from any big-box store without arousing suspicion. In fact, growing with CFLs is what I did for my first grow and I got them from a local Home Depot. I imagine that my first grow would’ve ended the same (or even better) had I used small household LEDs instead of CFLs, though they weren’t available back then. Learn more about growing with CFLs.

If you are considering this for the first time, you may be surprised to learn that, because of the way the laws about customs work in America, it is actually reliable and safe to buy your cannabis seeds online from a reputable seed bank as long as you get it from outside the US (sending seeds from one place to another in the US can get you in big trouble though!).

You can grow cannabis almost anywhere that has easy access to water and fresh air…

One nutrient system to rule them all…

LEC (Light Emitting Ceramic) is a brand name for a type of light (CMH – Ceramic Metal Halide) that has existed for quite a while. This type of light has come back into vogue after some rebranding, partly because it has some very positive traits for growing cannabis compared to HPS lighting. For one, LECs have a more natural color that makes it easier to care for and diagnose plant problems. Plus, it’s a lot better for security to have a light that doesn’t scream “WEED GROWING HERE!” like the unearthly yellow hue of an HPS. They produce significant levels of UV light, which can possibly increase trichome production. Additionally, they don’t seem to emit EMI (Electro-Magnetic Interference) as much as their noisy HPS cousins which means you’re less likely to have a HAM radio enthusiast accidentally tracking down your grow. The plants grew surprisingly fast under a 315 LEC and we were impressed by the yields we achieved on our first grow.

Only feed nutrients at full strength if the plant is showing signs that it needs more nutrients (lower leaves are turning lime green, then yellow, then falling off – the first sign of a nitrogen deficiency, the most common type of deficiency – if the plant is not getting enough nutrients).

After your cannabis buds have dried (thin stems snap, but the thicker stems are still a bit bendy), it’s time to start curing them so they’re smooth, taste good, smell good, and have the best effects.

Common cannabis-friendly potting mix brands in the US:

What space works best?

To cure your buds, put them in tightly closed quart-sized mason jars in a cool dark place. Fill each jar loosely about 3/4 of the way full.

Young growing cannabis plants grow fastest when temps a bit warmer, in the 70-85°F (20-30°C) range.

Because temps are so important, it’s best to be able to have some amount of control over the temperature of your grow area. When growing indoors, your grow lights will give off heat. Generally, the more powerful your lights, the more heat they give off.

But when you do know someone who has experience growing cannabis with a particular brand of LED grow lights, you know that the lights will work for growing cannabis. And if you have access to their grow notes, you’ll also know exactly how to use the LED to get the best results.
