How To Grow Marijuana From Seed Canada

All you need to get started on the road to grow your own weed at home quickly and affordably. Learn how to grow weed from the pros. With any luck, Canadians will be able to legally grow recreational marijuana in their own backyards, maybe even by this spring with the feds expected to introduce legislation legalizing weed this week. The president of Nextleaf Labs says the process isn’t too difficult and Canadians have plenty of good reasons to give home growing a try.

How To Grow Weed: A Step-by-Step Guide For Beginners

Looking for the basics of how to grow marijuana? Here are the tools and information on how to grow weed affordably and effectively. All you need is a small discreet space and a little bit of a budget to get started on your indoor pot production.

Grow Tools

The first thing you’ll need is a place to grow. I recommend getting yourself a decent grow tent. They’re cheap, made to grow inside of and can be put up and taken down quickly by one person. Some tents come with packages that include all kind of complicated hydroponic equipment. Your best bet is to purchase only what you need inside the tent and to learn how to grow weed without the expensive plastic. Some even have separate chambers for vegetative growth and cloning, making them perfect for people living in one-bedroom apartments or studios with limited room to grow.

First, you’ll need a growlight. I like HID (High-Intensity Discharge) lighting – HPS (High-Pressure Sodium) or MH (Metal Halide) systems with ballasts, bulbs and reflectors. If heat from these lights will be an issue, there are also LED (Light-Emitting Diode) and CFL (Compact Fluorescent) systems you can employ. Be sure to get a light that covers your tent’s footprint and invest in a decent timer to control when your light turns on and off.

You’ll also need an exhaust fan and activated carbon filter to reduce heat and eliminate odors. Be sure to get one that’s rated for your tent’s size with the proper ducting size. A clip-on circulating fan will keep air moving and stop it from being stagnant. A thermometer/hygrometer is also a must for keeping track of temperature and humidity.

If you don’t have access to marijuana seeds or clones from a dispensary or friend, you’ll need to get some cannabis seeds mailed to you. Don’t have them mailed to the same place you plan to grow if you’re not growing legally. Don’t just learn how to grow weed, learn how to be discreet and not brag or bring attention to yourself.

A simple loose and airy soil mix in 3-5 gallon buckets are great for beginners and much more forgiving than any hydroponic system. Be sure to cut holes in the bottom of the buckets and use saucers under them to catch any overflow. You’ll need to purchase nutrients to feed to your plants as they grow and a watering can as well.

How To Grow Weed

After you’ve planted your seeds or rooted your clones, it’s time to get them growing. Lower your reflector so that it’s closer to the plants rather than making them stretch to reach for light. Raise the lighting system as your plants grow. Set your light timer to be on for 18 hours per day and off for 6 hours. During this vegetative stage, the plant will grow leaves and branches but no flowers (unless it’s an auto-flowering plant).

Avoid overfeeding and overwatering your plants at all costs. Err on the side of caution as it’s always easier to add more nutrients or water than it is to take them away. Marijuana roots prefer a wet/dry cycle so lift up your buckets and you’ll get a better idea for if they need watering or not by the weight. The first sign of overfed plants is burnt leaf tips. The first rule of how to grow weed is to learn to stay off of its way sometimes.

Anytime space is limited for growing, some basic rules apply: Since square footage is at a premium, plans must take full advantage of each available inch. This means choosing between growing indica-dominant strains such as Hashplant, Afghani #1 or planning on using drastic trellising and training techniques if growing out sativas such as Super Silver Haze, Jack Herer or Kali Mist.

Pruning For Higher Yield

When pruning, start early and often. Cut or pinch branches just above the node where two new shoots will emerge. If you stay on top of this process, you’ll have plants that look like bonsai bushes, with plenty of bud sites but not a lot of stretching out and big gaps between nodes. This is the efficient way to get bigger yields out of small spaces but your vegetating time will increase so factor that into your schedule.

Don’t prune or pinch plants at all once they’ve begun flowering – you’ll only be decreasing your harvest at that point. If the branches are threatening to reach the light, bend them or tie them down to keep them from burning. A trellis system constructed from chicken wire at canopy level (aka the ScrOG or Screen of Green system), will further spread out bud sites and increase your yields considerably. Simply train growing shoots to grow horizontally along the bottom of the screen to fill empty spots.

Flower Power

Indoors, The decision of when to induce flowering in your plants is entirely up to you. If you want to learn how to grow weed, it’s important to determine how much space you have and to factor in the fact that your plants will stretch for at least a few weeks after flowering is induced. I usually recommend one week per gallon of container, so a plant in a five-gallon bucket should get approximately five weeks of vegetative time.

When you’re ready to begin the flowering stage, switch your timer to a 12 hour on/12 hour off light cycle. Be sure never to interrupt the 12-hour dark period with any light. This confuses your plant and can cause serious problems.

Change your feeding regimen to one suited for flowering. Plant nutrients generally come in vegetative or flowering formulations so switch over to a “blooming” solution. Depending on the flowering time of your strain, determine when you have two weeks or so left and begin the flushing process. If you’re growing a 60-day flowering strain, start to flush your grow medium with only plain water around day 46.

Harvesting, Drying and Curing

Knowing when and how to harvest your buds is as important as knowing how to grow weed.

Use a loupe or a strong magnifying scope to take a very close look at the trichomes; the tiny glandular stalk and head sometimes referred to as “crystals”. Up close, they resemble little glass mushrooms with a stem that forms a bulbous round clear top. Inside that gland head resides the psychoactive compounds (THC, CBD etc). Harvest when the majority of the gland heads begin to go cloudy white and before they’ve gone completely amber. Harvest when they’re mostly amber if you desire a more lethargic stone.

Post-harvest, you will trim and hang up your buds to dry. This process should take about a week or two depending on the humidity and heat in your area. It’s always best to keep this process slower than 3-4 days in order to ensure you aren’t locking in that “green” chlorophyll taste. Add a humidifier to your drying room if you think your nuggets are drying out too quickly. Never leave a fan blowing directly onto your drying colas but make sure air is circulating to avoid mold and bud-rot.

After you’ve determined that your buds are sufficiently dried you’re ready to jar them up for the cure. The stems should snap instead of bending and the outside of the flowers should feel bone dry to the touch. The truth is there is still plenty of water stuck in the bud and the curing process will slowly “sweat” out the remaining liquid.

Always use opaque jars (ones you can’t see inside) and place them in a cool dark place. Open up the jars to determine the level of moisture and leave them open if there’s any condensation forming on the inside of the glass. Slowly but surely, if you open and close the jars once or twice a day, the moist air will be replenished by dry air and the water that’s stuck in the middle of your bud will work its way to the outside and then out into the air altogether. After three weeks to a month or so curing, your buds should burn and taste perfectly.

Pro Tips for Proper Drying and Curing

A key part of learning how to grow weed is mastering drying and curing techniques. You do not want marijuana to dry too quickly or too slowly, as the ideal drying time for a healthy and flavorful marijuana plant is 10 to 14 days. In this video, you will learn the perfect temperature and humidity to dry and cure weed, as well as pro tips that will teach you how to grow weed and trim your plants like an experienced veteran, leaving you with a grade-A product.

Tips on How to Grow Weed: The Smart Pot

Attention to detail is essential if you are a beginner who is trying to learn how to grow weed. Even the most inconsequential detail could be the difference between a healthy plant and a dud. In this video, learn about the best type of container to use to grow your marijuana plant. We recommend a “smart pot,” which is a container that is made of breathable fabric that allows the roots of your plant to grow much larger. Larger roots mean a larger marijuana plant, which means a more bountiful weed yield when the time comes.

Could you send me directions to grow marijuana outside from start to harvest. Please.

Germinate your seed, put it in the soil, water daily and wait for the right season! :p

When you say right season, do you mean plant in spring and harvest in the fall ?

start your seeds 6 weeks before the last frost date in your area. place them in a sunny window over a heating pad. remove the heating pad once they germinate. if you are using feminized seeds expect one third to be males. if the seeds are not feminized expect 50% to 75% to be males, so germinate
enough seeds to cover that which gets pulled out in august as male plants. i use a jewelers loop to look at the crystals on the buds. harvest when halve of them are amber. it is best to harvest when the moon is in an air sign, plant when the moon is in a water sign.

I live in spokane wa and want to try a outside grow could you. Could you send me some info. from start to finish including best time to start a outside grow? Plz & Thank you fellow stoner.

In LaK’esh Ala K’in my Friends, i have a question regarding nutrients. i am growing 4 plants indoors under a 600 watt Halogen bulb, i would like to grow all natural and am using fish fertilizer during veg growth, is continued use during flowering a good idea or is there a natural flowering fertilizer that i can use? Gratitude for this site and the life giving info that is provided here.

Switch to a fruit bat guano for the phosphorus and drop the nitrogen mutes as they’re not necessary after budding commences

Nice article and useful for someone with a bit of xp under their grow belt. However this is not a step-by-step guide for beginners as a beginner doesn’t know how to setup their light, how to nurse their plant, when to shift stages, how to setup their grow space and etc etc…

This is a general overview of how to get your plant to yield and not be a dried up husk at the end!

I am definitely interested in seeing more research. Is anyone else concerned about a company that sells nutrients telling us to keep using nutrients through harvest? All I am saying is that the possibility of bias or marketing strategy is there. I am not saying they are wrong…

Not flushing would be one less change in routine and easier for most growers, I would think.

Grow journals are strongly encouraged. If you do not have one, make one! No better way to learn than through trial and error.

I’m growing a couple of plants and I need some advice I’ll send you a pic of my plants and if possible can you tell me what I’m doing wrong please and explain the to me the pic of the one flowering

I live in the desert where 100+ temperatures are normal in summer. I saw you recommended a thermometer/hygrometer to monitor temp and humidity, but I never saw what ranges we should be going for?
With lights and outside temp versus house ac my grow area is topping at 88-92F, is that ok?

what are the best things to feed your plants during bud stage?

what are the best things to feed your plants during bud stage?

i used starter fertilizer once and burn the plants. today i use fish emulsion once a month during growing and every two weeks during bud. i grow outside. i would not want fish emulsion indoors

I am a beginner and need info on how to grow.

any body else growing outside and having trouble with spotted lanternfly? they are not on the hop bines, but are all over the marijuana. Any helpful hints?

Use BTK it will take care of any pests.

I’m an unexperienced young rookie to growing pot plants, I smoke quite a bit so I decided it might be a good idea to grow to save cash. I have helped grow once before, and I’m using the same soil from that plant in a new cup. I started the process with the paper towel trick, its been 5 days and it has a long white stem like thing. I put it in a cup with the stem facing downwards and the three decent sized holes at the bottom. I’m using some sort of bright white light and I have my window open with a screen and ac periodically kicks on every 20 minutes or so. I put it on the windowsill, I was wondering if this will even grow, I’m not really that worried about it since I have a bunch growing outdoor around the same age, plus extra seeds, but I want to start growing indoors with what I have available. the light is a Intertek household use light, 250 watts, but bright as all hell. house base temperature usually never breaches 80. window is facing where the sun rises, therefore, I think it will get enough orange light to be healthy. And I’m supposed to be getting larger pots very soon, where I’ll transplant then seedling once it gets to a decent 5 or 6 inch tall. That will be the final transplant. I realize the light isn’t ideal, but is the air flow ok? also I live in Florida so that may or may not change things, and if you have any tips I’m happy to hear them.

straight up indoor growth is the easiest to master
there is no way a window will provide you adequate light, I tried and I am in the same area as you.
you will need at least a decent grow light I use a 1000 watt from GrowKing off amazon about a 100 bucks has a blue and a yellow setting grow and flower, and you will see amazing growth with them. make sure you have a big enough container for them, at least 2 or 3 gallons and decent soil like foxfarms

Hey, here is a small piece of information. Every first time grower should be aware of.

Cannabis deficiencies and other cannabis leaf symptoms can be a nightmare for any grower. But fortunately, many strange weed leaf spots, marijuana leaves turning yellow, the whole marijuana plant turning yellow, and other strange cannabis leaf problems or deficiencies can be fixed.
1- Solution For Calcium deficiency:

– Supplement with extra Calcium

– Dolomite Lime – For Soil Growers (Organic)

2- For copper deficiency:

– Adjust pH to Correct Range

– Give the Right Nutrients

– Take Good Care of the Roots

– Watch for Leaf Recovery

3-For Heat Stress:

– Keep roots cool

-kelp extract for roots

How to grow your own marijuana in Toronto

Few things are more satisfying than growing your own stash. With any luck, Canadians will be able to legally grow recreational marijuana in their own backyards, maybe even by this spring with the feds expected to introduce legislation legalizing weed this week.

The federal government task force that submitted its report in December recommended allowing the personal cultivation of cannabis for non-medical purposes, to a maximum four plants per residence. They haven’t completely freed the weed, but you can still get high thinking about the savings from growing your own stone.

My local storefront dispensary sells dry leaf for $10 to $15 a gram. A single plant can yield about 125 grams on average, though double that and more is possible, which works out to a little less than a cool $2,000 you won’t have to spend on weed. The only investment you’ll need to make is for seeds going from $60 and up for a package of five that you can order online and have mailed to your door.

In advance of the happy day when Canadians can grow their own, here’s some basic advice on planting successfully outdoors. (Let’s leave indoor growing for another day.)

Don’t let males spoil the party

Pot plants are either male or female. For stoning purposes, you want female plants, and you don’t want them to make contact with male pollen. A female plant pollinated by a male stops producing THC (the ingredient that gets you high) and concentrates its energy instead on making seeds.

I recommend buying “feminized” marijuana seeds that grow female plants. If a male plant gets into your grow, yank it out and get it away from the females as soon as you can tell the difference, which will take a few weeks.

How to tell the difference: the female will develop two upraised feather-like stigmas that are usually white- or cream-coloured, generally found on the main stalk. The male plant grows little clusters of bell-like sacs that give off a yellow- coloured pollen.

Preparing your seeds for planting

Start in early April. First soak seeds in water over night. Then place the seeds between thick paper towels, lay them on a plate and cover with water. Place the plate in a warm, dark area and wait for the seeds to crack open. Good seeds can take two to seven days.

Let the taproot grow a little, up to 0.5 cm. Then carefully plant the seeds in a small container in no more than 1 cm of soil. When shoots appear, the seedlings need lots of light, about 16 hours a day, and it has to be of a decent intensity, so put them under a grow light. You want the seedlings to grow to no more than 10 cm, which means the lighting system needs to be elevated to maintain a healthy distance (about 95 cm) as the plants grow taller. Plan on keeping your seedlings under lights for 30 to 45 days before moving them outdoors.

Important tip: don’t just stick them on a windowsill. They’ll be too stringy and likely won’t survive the move outdoors. You want these babies to grow sturdy stalks with a robust root system. Use a plant starter fertilizer (with a 10-52-10 mix) to promote root growth, readily available at hardware stores and garden centres.

Tricks for the move outside

Your plants need a spot with good soil and full sun.

But before they go in the ground, you have to toughen them up. You do this by giving them short bursts of direct sunlight – a minute or two on the first day and five minutes on the second day. Keep your plant in a shady area outside after each dose.

On the third day, give the plants 10 minutes of direct light, 15 the next, 30 after that, and then your plants should be hardy enough to go into the ground.

It’s a good idea to transplant using a starter fertilizer again. Also, pot needs room to grow the more space you give it, the better the yield.

From here on in, the plants need regular watering (a couple of times a week should suffice). Pot plants do not like continuous irrigation, but at the same time you do not want the roots to dry out. Let the surface soil dry out to about a depth of 5 cm before watering.

In late June, you can apply a 20-20-20 fertilizer to stimulate vegetative growth, and again in mid-July. Then in mid-August I recommend using a fertilizer that promotes flowering (5-30-5). No more fertilizing after this point.

Depending on the variety, your plants should be ready to harvest sometime in September or early October. Leaves can be used for cooking and the buds for smoking.

Watch out for mould – and lilacs

After growing weed for more than 40 years, I still find new and unique problems. The pitfalls are too many to get into here, and besides, you’ll learn through experience. For example, I learned a couple of years back not to grow next to lilacs, which have a tendency to get mouldy toward the end of the summer and infect your weed. You should not smoke mouldy weed.

Secrecy is paramount

The biggest threat to a successful harvest is thievery. So you may need to trim the plant to a size that keeps it hidden or do your planting a little later in the year, on the first or second week of July so the plants will only grow to about 1 metre.

Alternatively, you can stake the plant’s branches to the ground and force them to grow sideways. Branches may splinter, but that’s totally cool as long as they stay connected to the rest of the plant. Hidden bonus: staking increases your plant’s exposure to sunlight, and that means higher yields.

Drying your buds

Do this on drying racks in a warm, dry and airy location indoors, making sure to give the buds lots of room. Pack them too tight during the drying process and you risk losing the crop to mould and rot. Your buds should be ready to smoke after two weeks of curing, depending on humidity levels. Take your time and keep an eye out that the plants don’t become too dry. Trim and enjoy! 3

Grow expert Tom Ulanowski, president of Nextleaf Labs in Coquitlam, says the process isn’t too difficult and Canadians have plenty of good reasons to give it a try.

From seed to plant: How to grow your four legal cannabis plants Back to video

“It’s a lot cheaper than buying from a store or LP (federally licensed producer), especially if your grow is low-tech or if you choose to grow outdoors,” said Ulanowski, a chemist and former quality-assurance manager at Canna Farms.

“You have total control and know exactly what your inputs are. And gardening can be fun and therapeutic, as well.”

Once a grower has their gear and has legally acquired seeds or seedlings (the B.C. Liquor Distribution Branch will sell seeds in B.C.), here’s how Ulanowski recommends they put them to good use.

Fold a piece of paper towel twice into a pocket, place four seeds inside and dampen it with water. Seal the pocket inside a ziploc bag and put it in a warm place. After about a week, the seeds will open and plant tissue will show.


Carefully take the four seeds and put them in peat pellets or small pots with damp peat-perlite mix or coco coir, about 2.5 to five centimetres deep. Set an 18-hours on light cycle, with the six hours off at night. Stalks will emerge in a week or two, and nutrients and water can be added. Vegetative growth will continue for a month or two, at which point the plants should be transplanted to larger pots. Trim away larger leaves.


Once the plants reach between 30 and 60 centimetres tall, give them a 12-hour light cycle. They’ll start flowering and reach maturity within eight to 10 weeks, depending on seed variety. Trim leaves two or three times during flowering. Once the plants mature and their trichomes (hairlike glands) turn cloudy, it’s time to harvest their buds

Cut off the larger branches and hang them upside down in a dark environment with about 50 per cent relative humidity and 20 C for a week or two. The drying process is done when smaller stems snap, not bend. Trim off leaves and remove dried buds. Put them into a mason jar with a special humidity-control pack. Keep the jar in a dark, cool place like a cupboard, opening the lid to “burp” the buds every few days. After a week or two they’re ready to consume.

Ulanowski said it’s crucial home-growers keep safety and cleanliness in mind. They should abide by dried cannabis possession limits in their province (1,000 grams at home in B.C.) and make sure their landlord or strata council allows home grows.

“Stay away from pesticides, if possible, and instead rely on sanitation, environmental controls, and beneficial insects to control pests and disease,” he said. “Be discrete for obvious reasons. For example, B.C. laws require you to hide your plant — it can’t be in public view.”
