Seed to produce cannabis

Hot Cannabis Seeds To Grow in 2022

Three cultivation experts fill us in on what they are excited about as we enter the outdoor planting season.

Luckily for us, cannabis was made illegal. After all, if the U.S. government had not decided to criminalize marijuana, starting with a tax for growing it, we wouldn’t have nearly as many different types. When cannabis growers and breeders were forced underground, they used male and female plants to create their own seedstock. The illegal distinction borne by the cannabis plant has led to it being one of the most diverse botanicals on the planet. When the War on Drugs meant Americans could no longer get landrace genetics like Acapulco Gold from Mexico, we looked further toward Amsterdam’s marijuana melting pot. The fusion of American cannabis enthusiasts and High Times legends like Sam the Skunkman, Ed Rosenthal, and Steve Hager with Dutch seed companies blessed the world with delicacies like Super Lemon Haze and provided the platform to promote them. Today, the worldwide cannabis seed market is a thriving industry.

Seed germination for outdoor growing starts in spring. Seeds require 10-15 days longer than clones, so the end of April is an excellent time to pop them to get the 2022 outdoor harvest outside by Mother’s Day. We checked in with three ganja growing all-stars to see what cannabis combinations they’re excited about this year.

What seeds are you excited about for this planting season?
For this planting season, I’m super-juiced to re-run Humboldt Seed Co’s Squirt (feminized) for year three. I can smoke that super-optimized modern Tangie cross all day, every day, and it makes a great salad with another sativa during the day or some gas at night.

I’m also hyped to bring back HumSeedCo’s Hella Jelly (fems) for year two as a super-agronimized modern sativa that finishes early and has mad cherry and cotton candy taste and zippy daytime effects.

I’m stoked to run Archive Seeds Dosi-Tree outside for the first time for that Dosi gas plus Lemon Tree’s size and syrupy lemon smell. Yum! Last year it was In-House Genetics’ Slurricane IX—that killed!

And lastly, I’m pumped to run Terp Hogz Geneticz Z3 for the first time this year! I think I’ll always want some Zkittlez in the garden, and Z3 is a way to get at the root of some optimized Z terps, as opposed to chasing new Z crosses. I can’t wait to have a pound of Z3 for Thanksgiving! Terp Hogz is selling seeds direct to your door on NXTLVL delivery in the Bay Area—if you don’t know how cool it is to shop, buy and get Terp Hogz genes delivered in a couple hours—now you know! It’s so clutch.

Do you typically grow from seed? If so, why?
Yes! I like the vigor of seeds, especially regulars—they get huge outside! There’s also less chances of a virus or pest infection from seeds vs. clones. I buy seeds all year and they keep well until it’s time to plant. (But I still might get a clone of Jokerz from Compound Genetics for this year, and if I do, I’m all about it!)

What does your grow setup look like?
I start popping indoors the first day of spring and raise babies inside where it’s warm, then sex the juveniles, and harden them on the porch in The City, before transplanting the keepers into 30-gallon fabric pots outdoors in the NorCal sun by Mother’s Day! We try and KISS (keep it simple, stupid). We use Fox Farm Ocean Forest soil plus amendments and well water on a drip timer. And BT to fight the caterpillars!

Are there certain types of cannabis or specific cultivars that do well where you are growing?
Yeah, I’m an outdoor NorCal Bay Area grower, and I’m deliberately running Humboldt Seed Co, Archive, and Terp Hogz because I think their gear tends to be tested and screened for outdoor runs. I know HumSeedCo does a bunch of mixed-light testing, and Terp Hogz in Mendo also works in mixed light. Archive’s stuff seems to be developed more indoors in Oregon, but I know that Lemon Tree has killed it outdoors in Santa Cruz.

I want to run stuff that’s been tested outside, for sure. Lots of the latest crosses are bred and tested inside and many breeders and growers don’t know how they’ll react to the variations in heat, humidity, etc. outside. I want stuff that’s hard to fuck up, as opposed to some diva that molds the second it rains, or some crazy sativa that won’t finish until November. But that’s just me! Everyone’s needs are pretty specific!

Do you typically grow from seed? If so, why?
No, but I have done so with Oaksterdam University students over the years often.

What does your grow setup look like these days?
A simple 4′ x 4′ area light up with LED lights in a larger room that I have found no need for AC to cool.

What has been your experience growing autoflowers?
To me, this is the best reason to grow from seed. They only come this way and are getting better varieties all the time.

Are there certain types of cannabis or specific cultivars that do well where you grow in Oakland?
We have a mix of urban growers that are survivors. Many obstacles to keep from having a successful harvest in tight city living. I grow inside due to this better neighborhood policy. I find less issues and arise with having long-term success. But I do know a few good areas that have outdoor gardens with little to no worry for either the garden or neighbors with bad smells.

What seeds are you excited about this year?
Since I live on Vashon Island in the Pacific Northwest, I have to choose seeds that will finish flowering fast enough during our short summers. I’ll mostly be growing autoflowers so I can germinate them on June 1 and harvest at the end of August before the rains start. I am excited to grow the Purple Pope collaboration between Gnome Automatics and Night Owl Seeds. The flowers smell of sandalwood, lemongrass, and yuzu. Northern Cheese Haze from Mephisto Genetics is always a winner for me too. It captures some of that fresh sunshine-dried linen sweet smell of haze with the bloomy-rind cheese funk that we love cheese strains for.

The most reliable photoperiod for where I live continues to be Mandelbrot’s famous Royal Kush from Mendocino, which will often finish in 50 days. There is a new collaboration between Emerald Mountain Legacy and Mean Gene From Mendocino called Royale with Cherries that blends the gas and shorter flower times with Mean Gene’s Cherry Lime Pop which contributes a complex Maraschino cherry sweetness. It is exquisite. Last summer, it finished well ahead of all the other photos. And it hashed well for us too.

How was the 2021 Autoflower Cup? Are you experimenting with autoflowers?
The 2021 Autoflower Cup was a great gathering. For so long, autoflowers really didn’t perform as we wanted. But the modern era of autoflowers are so much better tasting and yielding. And because they can be grown nearly everywhere in the U.S., they are quickly gaining a following. And, of course, since autoflower enthusiasts are so often ridiculed by photoperiod growers, it is nice to hang with a big group of people who share this special interest.

I am past simply experimenting with autoflowers at this point and have fully embraced them. Before this season, I have grown 156 varieties. I’m at the point now where I believe in them, understand their advantages and disadvantages and can really work with them to meet my cultivation goals.

Grow Weed Starting From Seed

“Don’t judge each day by the harvest you reap but by the seeds that you plant.”

Growing your own cannabis plant starting from seed is a remarkable journey. Understanding the biology of the plant is one thing, but comprehending how a little miracle bean can turn into a gigantic tree producing flowers that can affect your body and mind is nothing short of an evolutionary miracle. Or rather a co-evolutionary story of plant and human.

Start Growing Weed From Seed

Our favorite thing about growing your own weed starting from a seed , rather than a clone, is that you get to see the full life cycle and enjoy a plant that is unique, just like you. An entirely new genetic makeup will enter the world for the first time, and if you’re lucky, something remarkable might be born.

Raising a cannabis seedling , however, requires some patience, gentle hands, and a smidgen of luck. Thankfully pot seeds are remarkably vigorous because they are what’s called endosperm seeds , which means they have almost pre-formed cotyledon leaves before you even add water. Below is a brief guide on the techniques we have found yield the most success when starting seeds and raising your seedling to a healthy plant ready for transplanting. And, don’t forget, a Pot for Pot’s Complete Grow Kits take the guesswork out so you always wind up with a splendid harvest!

1) Germinating Your Cannabis Seed

To accelerate germination, soak your seed in a small container with lukewarm water and place it in a dark and warm place (like a kitchen cabinet) for 12-24 hours, but no longer. By drenching the seed, it absorbs the water thoroughly, activating the germination process on a physical and chemical level. Doing this helps to loosen the shell as it becomes a little softer making it easier for the embryo to crack it open. When your seed sinks to the bottom, it is ready to be planted, and sometimes the seed will pop out a small taproot. A seed can still be planted though if it does not sink or put out a taproot. When a seed pops a taproot (often called a tail), it becomes more vulnerable and it is better to plant it before this root emerges.

2) Planting Your Weed Seed

We see best results with seedling pellets that are made of a mix of compressed peat moss and coco husk. To expand, soak it in water for 10 to 15 minutes. Using warmer, lukewarm water, instead of cold water, will speed up the time the pellet takes to fully expand. Once your seedling pellet has absorbed enough water and has expanded to its maximum size, gently squeeze to remove excess water. The growing medium should be like a damp sponge that would not leave streaks on the table. Dig a small hole about 1/4 inch deep for your seed. Use a spoon to lift the seed out of its bath. If it has popped out a taproot be careful not to damage it. Gently place the seed into the hole and lightly cover it with dirt from the pellet. Now that you have started the germination process, your seedling will come above ground within two weeks. The older the seed, the longer it takes for it to germinate.

3) Weed Seedling Sprouts

Perhaps the most exciting stage, your plant baby will come above ground in 1-2 weeks, with the average popping up in 5 to 7 days after planting. As your seedling comes above the soil, its shell might take a few days to fall off. It’s best to leave it alone, nature has the job covered. If it does not come above ground after about two weeks, the chance of success is dramatically reduced, and it’s best to try again. Even the best seeds have an 85% germination rate. When your seedling comes above ground, it is going to want to see a direct light source.

4) Lighting for Your Cannabis Seedling

Marijuana seedlings require a medium amount of light — enough to get energy to grow, but not too much light that to get burned. Leaving your seedling in direct sunlight will cause the leaves to curl, while too little light will cause the seedling to stretch. If growing outside, seedlings want to see a direct light source to stop them stretching. If inside, a sunny windowsill with more than half a day of sunlight works wonders. Otherwise, 24 to 30 inches from a grow light is an excellent supplement. Your seedling should not stretch more than 6 inches at most.

5) Watering Your Cannabis Seedling

For cannabis plants young and old, it’s best to use bottled, distilled, or filtered water as these are without chlorine. If using tap water, let it sit for 48 to 96 hours before watering to dissipate any chlorine. Chlorine can also be eliminated by boiling for 20 minutes. Under normal conditions, after soaking your seedling pellet, it should contain all the moisture your plant needs before it comes above ground. As it grows, it will only need about a shot glass worth of water at most per week to keep the medium damp. Seedlings don’t drink a lot of water, which makes sense given their size. Your plant will do better in a growing medium which is damp but not soaking wet. Overwatering is just as deadly as drying out!

Damping off happens when the seedling is in too moist of an environment. The young plant’s immune system is not strong enough to ward off a fungus that results in the plant rotting from the bottom of the stem. When this happens, the plant will bend over and die if not treated. To help fight the infection, lightly spray a 0.5% solution of hydrogen peroxide around the affected area. However, the best option is to avoid this by not exposing your seedling to too much moisture.

6) First Cannabis Seedling Leaves & Hardening Off

The first set of leaves to come above ground are called the cotyledons . These little leaves are packed with energy and will grow to about 1/4 in in size before eventually falling off. Your second leaves to emerge will be single blades and will be serrated, looking like regular pot leaves.

They will become several inches in length. During their growth your first actual set of leaves will appear. These are typically three blades. Around this time is when your plant is “hardening off”. You will notice that the stem will start to develop a thicker skin and harden off. As the leaves of the plant get bigger, they can gradually handle more sunlight, so move it into more direct light– the more light the better!

7) Transplanting Cannabis Seedlings

About 10 days after germination, when the baby cannabis plant has hardened off, roots will start emerging from the bottom of your seedling pellet and the plant is ready to be transplanted into a bigger pot. Be very careful not to damage the roots during this stage. Any stress will slow its growth.

Dig a small hole in your bigger pot for the seedling, sprinkle some rooting booster in the bottom of the hole then carefully plant the whole seedling pellet holding your weed baby.

Now bury so the base of its stalk is level with the topsoil. Give it a watering to set the roots in the ground, then hold off watering until you pick up the pot and it feels light in weight.

8. Separating the Girls from the Boys

At about 4-6 weeks into your plant’s growth , you’ll be able to determine the sex of the plant. You’ll want to separate and dispose of any male plants. This is an important step for growing marijuana because the female plants are more potent and valuable. You also don’t want male plants to compromise the growth of your female plants.

Why Do You Only Want Female Weed Plants?

Only female marijuana plants produce THC buds that are high in potency. You want to make sure your Cannabis plants are all female. If you have a male plant, it can fertilize the other female plants, and they will work to produce seeds instead of flowers and nugs.

It’s essential as a grower to know the difference between a female and a male plant so that you can remove the male plants before they contaminate your crop . Unfortunately, you have a 50/50 chance of getting a male plant when growing a plant from a seed from a nug.

There is a massive market for seeds that will only grow into female plants. But even these seeds are not a 100% guarantee you’re going to get a female plant. To ensure a good crop, you’ll want to germinate and plant many marijuana seeds and then separate the females from the males when the plants begin to show their sexuality.

How to Tell if a Weed Seed is Male or Female

As your plant matures sexually, it will develop between its nodes. Nodes are the area of the plant where the branches connect to the plant’s stalk. The distinguishing characteristics that will help you identify your plant’s gender:

  • Male Plants : Small pollen sacs will cluster in the nodes.
  • Female Plants : Stigmas will develop in the nodes. The stigmas can catch the pollen of male plants. Stigmas have hair-like veins that will extend from the sacs in the nodes.
  • Hermaphrodite Plants : These plants have both the stigmas and pollen sacs in their nodes. These are female plants that develop both sex organs when exposed to a lot of stress.

Once you can identify the sex of your plants, you’ll want to remove the male or hermaphrodite plants because they can negatively affect the harvest of your female plants. That’s why it is crucial to germinate and grow several cannabis plants to this stage to ensure you get at least one healthy female plant.

9) Grow Weed Plant, Grow!

Suddenly, before your very eyes, the plant will transform. She will grow in height and branch out, putting off leaves and a network of branches. It is your job as the grower to meet her needs so that she can reach her full potential. With a good grow kit, this means as much light as possible and lightly watering only when she is thirsty.

This is considered your marijuana plant’s vegetive stage. The goal in this stage is to keep her healthy and allow the plant to grow as big and strong as possible so that she can hold many, many flowers.
