How to re-veg marijuana plants
Cannabis is an annual flowering plant, its life cycle limited to just one season. In the wild, it grows from a seed, flowers, and dies, all between spring and fall. Once a female plant dies, it will drop seeds, which are responsible for carrying genes through to the next growing season.
But it’s possible to hack this process to give cannabis plants a second growing season. A grower can manipulate a plant and force it to revert from the flowering stage back to the vegetative stage again. This process is known as re-vegging, or regeneration, and it allows you to harvest buds from a plant, then grow the same plant again for a second harvest of buds.
Cannabis has a short-day photoperiod, meaning it transitions from a vegetative period to a flowering period—when it starts growing buds—because the amount of light it receives reduces. This happens outdoors as autumn approaches and days become shorter. Indoors, growers “flip” weed plants into the flowering stage by manually reducing the amount of light they get each day.
Altering a cannabis plant’s photoperiod schedule after harvest will allow you to re-veg it.
Benefits of re-vegging cannabis plants
Reduce vegetative periods
A cannabis plant that has undergone a full growing season will have a complex and robust root system. If re-vegging a weed plant, it will move through its second vegetative phase quicker if it has a mature root system, whereas clones or seeds will take longer to establish roots.
Eliminate mother plants
Growers will sometimes keep mother plants, which are plants that always stay in the vegetative stage for the purpose of cloning only. But keeping mother plants takes time and space. Re-vegging allows you to get rid of mother plants, freeing up space in your grow for plants that only produce buds. It also saves time and resources, as you won’t have to tend to mother plants.
The process of taking a clone from a flowering plant is a re-vegging technique known as “monster cropping” (more below), and it can produce more vigorous and bushier plants. If done correctly, monster-cropped clones have the potential to create plants with higher yields the second time around because of an increased vegetative mass, stronger stems and branches, and more nodes for potential buds.
Cloning/Preserving a phenotype
If cloning a weed plant, growers usually need to take a clone of a plant before it begins flowering. But if a grower neglects to for any reason, that phenotype, or the genes of that specific plant, will get lost. Re-vegging is the only way to preserve an exact replica of a particular phenotype once it has transitioned into the flowering state.
Disadvantages of re-vegging cannabis plants
Re-vegging is hard to successfully pull off, even for seasoned growers. It takes a few weeks for new growth to appear so you might be wasting time and space waiting for new growth only for it to not happen.
Most growers who re-veg say that yields decrease the second time around. So while re-vegging may cut down on the amount of time it takes to grow a plant, it might not produce as much.
Stress on the plant
The re-vegging process is highly stressful on a plant and even if it does re-veg successfully, aberrations often occur, such as unusual leaf growth and hermaphroditism. Re-vegged plants are more delicate and must be given more attention and care.
Types of re-vegging
There are a few ways a cannabis plant can revert from its flowering stage back to a vegetative stage.
Probably the easiest method, this will allow you to harvest a plant for buds and then re-veg it for a second growing season. This is typically done with indoor plants, as you’ll need to control the amount of light they receive.
When harvesting a weed plant, leave a few healthy buds and branches intact at the base of the plant. Reset the plant’s photoperiod back to a vegetative schedule: 18 hours of light/6 hours of dark a day (as opposed to the 12 light/12 dark schedule it had when flowering).
Also, change the plant’s nutrient regimen, giving it nutrients more conducive to early-stage growth. It will need more nitrogen for root and leaf development, as opposed to the high amounts of potassium and phosphorus it likely received during flowering.
Post-harvest re-vegged cannabis plants often take a little bit of time to take off at first and some strains may not even be receptive to this method at all. Early growth on a re-vegged plant may exhibit stress-induced mutations like single-fingered leaves and odd node patterning, but these issues should go away after a few weeks if re-vegging is successful. Plants that re-veg successfully can display increased vigor after the initial transition.
As mentioned above, cloning a plant while it’s in the flowering stage is called monster cropping. To successfully do this, take clones from the lower branches of a plant when it’s in the second or third week of flowering.
Take a clone as you normally would, but be sure to remove all visible flowering nodes from each clone. This will improve the clone’s ability to root out by halting flower production within the cutting.
As with post-harvest re-vegging, monster cropping may result in stunted and mutated growth at first, but with proper care and training, this method can produce massive plants with increased vigor and foliage growth.
Cannabis plants will unexpectedly revert back to vegetative growth if there is a disturbance in their photoperiod schedule—for example, if they receive 12 hours of light a day for a while, and then start to get more than that.
This can occur both indoors and outdoors, usually because of a light leak or a light timer malfunction when growing indoors, or from planting outside too early in the season when growing outdoors.
Even the tiniest of changes in a cannabis plant’s light cycle can cause it to flip back to a vegetative state, and some plants may even turn hermaphroditic, growing both male pollen sacs and female flowers.
From Seed to Bud: The Plant Life Cycle of Cannabis
The popularity of marijuana plants is rife at different angles. However, it is the simple life cycle that makes the herb unique. From a seed into a mature bud, the cycle is one of the easiest to master. Below is a breakdown of how the plant grows until it reaches maturity.
The life of a cannabis plant starts immediately when the seed is sown into the ground. The rate of germination of the seed depends on the conditions it is exposed to. First, if the seed is watered regularly, it germinates at a fast pace. Colour and texture determine the quality of the seed, and to a great extent, the time it takes to germinate.
A healthy seed should be dry and hard. It should also have a dark-brown color. It is advisable to avoid sowing seeds that are white or green since the probability of germinating is negligible. High-quality cannabis seeds take between five to ten days to sprout.
The Seedling Stage
The seedling stage in cannabis takes place immediately after the seeds germinate. A standard cannabis seedling should have leaves containing a single-ridged blade. During the growth stage, the cannabis plant should be green.
During the seedling stage, it is advisable to reduce the rate of watering to protect their delicate stems. Besides, the risk of the plant developing mold and getting diseases is also higher during the seedling stage.
The seedling should be watered after two days. Overwatering the seedlings is a common mistake many growers make, which might affect the time taken for the cannabis to grow and develop. Also, the seedling should be kept in an area with free circulation of air and sunlight. This allows the chlorophyll to form and crucial cannabinoids to accumulate in the leaves.
If the right conditions are adhered to, the seedling stage should take between two and three weeks. Most importantly, the seedling stage should also be exposed to a source of light for at least 18 hours a day. Sunlight is the most common source of light used by cannabis seedlings. However, the sophistication in technology has led to the improvisation of LED lights, which provide the same light properties as the sunlight.
The vegetative stage is considered the time when the marijuana plant starts to mature. During the phase, the leaves become full, and the stems sturdier. The rate of growth also hastens, giving the plant a bushy appearance.
During the vegetative stage, it is advisable to transfer the plant to a place where it will attain the full size. In addition, the watering style should be changed. In this case, the water should be poured further from the stalk to protect the roots from being exposed. The stage takes approximately three to sixteen weeks and requires about 18 hours of light.
During the flowering stage, buds start to form on the cannabis plant. It is also during this stage that the sex of the plant begins to manifest. Once the male parts have been identified, they can be separated to prevent them from germinating the female ones.
The formation of buds is more prevalent in week 6 and 7 in the cycle. It is also advisable to avoid pruning leaves and branches two weeks before the marijuana starts to produce flower buds.
During this phase, the plant should be watered less, and the plant exposed less to light. The plant should receive less than 12 hours of sunlight in a day. Less exposure to light allows the cannabinoid levels in the plant to increase. The rate of watering during this stage should be lower.
Once the buds have matured, harvesting can take place. It involves plucking the branches from the plant and hanging them to allow excess moisture to evaporate. It is also during harvesting that bud trimming takes place. This consists of removing fan leaves from the buds together with sugar leaves. However, the removal of sugar leaves from the buds is less common since they contain a high amount of THC. Once the marijuana trimming has taken place, the seeds can be prepared for planting again.

Seeded Buds: Why Does My Weed Have Seeds?
You are browsing online and checking out all the different strains. There is a local dispensary that is selling medical cannabis at an unbelievable price. Really? Only forty dollars per ounce? And it is a great strain that you usually buy. Seeded weed? What does that mean?

At the top of the discounted ‘flash sale’ status of the cannabis, you see a phrase that confuses the heck out of you. And it stands out like kind of a warning; “heavily seeded.” Unless you are a cannabis expert, you probably think seeds are no big deal. They are still natural, right? And they probably have the same amount of THC.
When a grower makes a little bit of a goof-up, and the cannabis is allowed to get frisky with other plants in the greenhouse, seeded nugs happen. Everyone loves a discount! They are a great deal. Having seeds in your whole flower cannabis must be just an aesthetic thing that people don’t like.
Think twice before you get the bargain basement cannabis loaded up with seeds. No, it’s not going to add more fiber to your diet (although you could use seeded cannabis for making edibles). But as far as using it in your pipe? Definitely read up on why it is discounted before you buy.

The Birds and The Bees: Cannabis is a Highly Evolved Plant
Did you know that about 80% of plants on the planet are self-pollinating? Cannabis is a highly evolved plant. It is a dioecious species, which means it has separate male and female plants. Cannabis plants have three sexes. There can be male plants and female plants. And occasionally, a strain will produce hermaphrodite plants (both male and female).
If you were walking through a medical dispensary’s greenhouse, you would see plants that have zero flowers. Lots of leaves, though, but no buds. Then you would see plants blooming with buds. Guess which one is the female plant?
The male cannabis plant is worth empathizing with. He tries hard but barely gets a date. The male cannabis plant typically has a thinner stalk and fewer leaves. But the male cannabis plant grows and produces valuable pollen taken by the wind or breeze to nearby female plants. (Cue the disco music). And that, ladies and gentlemen, is how marijuana buds are born.
Every time a cannabis plant seeds, it is a 50/50 split between male and female seedlings. Some strains can produce up to 75% of male plants. But you can’t tell in a greenhouse until they have started to grow. It usually takes about six weeks in the greenhouse before female plants begin to bloom. Then the male cannabis plants are separated from the female cannabis plants.
The female plants are valuable because they will produce crops of flowers or buds. Male plants, however, are not the star of the show, and they are either mulched for fertilizer or repurposed into other cannabis products.
What Happens to Male Cannabis Plants?
Dispensaries are interested in cultivating cannabis flowers from female plants. Some of the male plants are kept if they show specific attributes that are valuable for breeding. You plant corn, you get corn? It’s a little more complicated with cannabis. Most of the male plants are incredibly low in cannabinoids. Not all of them but most. And so, other than pollination, to a commercial dispensary, the male cannabis plant isn’t worth keeping around.
During the vegetative growth phase (when cannabis is maturing into a seedling), the male plants have higher THC concentrates in the leaves. It is only when the female plants mature to the adult stage that they have a higher potency. Female plants are the only sex to create sinsemilla. That is the compound that produces the psychoactive effects in THC.
Male cannabis plants don’t have a very long lifespan. Cultivators worldwide have tried to breed in high THC and bloom production in male plants, but with no success. You can’t delay the pollination process for male plants, nor can you breed enhanced resin production for male cannabis.
More sad news for male cannabis plants; their pollen is detrimental to female plants. So, if you have a happy crop of male cannabis plants sending their pollen over to the ladies on the other side of the aisle, it can stifle the crop. It will reduce the size and production of female cannabis plants.
Hermaphrodite Cannabis Plants Have It Worse
The creation of hermaphrodites or both male and female sexed organisms is a rare occurrence in nature. But the genetic anomaly can happen to any species on the planet. And that includes the cannabis plant.
Hermaphrodite cannabis plants are considered trouble. When they are discovered, they are separated from other female plants. A few hermaphrodite plants can ruin an entire harvest and jeopardize the quality of the flowers produced. They are found, uprooted, and destroyed in a way that does not allow them to cross-pollinate with any other plants. It’s very much ‘seek and destroy’ when a cultivator finds them in the greenhouse.
The potential for genetically mutated hermaphrodite plants to reproduce with quality strains is very high. So, it is very much ‘seek and destroy’ when a cultivator finds them in the greenhouse.

What Is Seeded Weed Good For?
When you look at a seeded flower, the composition seems similar but extra chunky. Throughout the bud, you will notice seeds of different sizes. Fully germinated and non-germinated seeds (or baby seeds). More fiber! So, the cannabis seeds must be good for you? Well, they are. Just not in your pipe or cone.
There is a market for marijuana seeds because they contain many health benefits. They are a great nutritional resource and have more than thirty (30) healthy fats. Some of the types of healthy fats include alpha-linoleic acid, which is the plant version of omega-3 fatty acid. They are also a high source of plant-based clean proteins.
Fiber! Boy, are cannabis seeds full of fiber, and they are great for digestive health. So much so that some clinical studies have suggested that cannabis seeds can reduce intestinal and colon cancers. Both soluble and insoluble fiber is found in cannabis seeds.
The soluble fiber is absorbed quickly and makes you feel full longer while providing energy. The insoluble fiber has a cleaning effect. It doesn’t digest but has an exfoliating impact as it travels through the digestive tract.
There are many supplements and nutritional products that are made from cannabis seeds. Also, for cosmetic products and skincare. Cannabis seeds are also high in an amino acid called arginine, which helps with muscle relaxation, blood vessel dilation, and reduced blood pressure. Cannabis seeds are often used for nutritional products sold for weight loss.
Why Are There Seeds In Cannabis Flower the Dispensary is Selling?
Full disclosure? Cultivators and dispensaries know that ‘seeded weed’ is a goof up. They know that it still can provide some wellness benefits. However, both the aesthetic and some of the seeded weed side-effects make the product less desirable to patients.
Does seeded weed still have THC and psychoactive properties? Yes. The cannabis potency is usually not any different, and it is still tested before being sold. The website of the dispensary will confirm the THC content in the description of the product.
Seeded weed happens when pollen from a male cannabis plant touches the female plant. Congratulations, you have a baby seed. But a lot of pollen can interact in a single exchange (from more than one male plant). That’s when you end up with bud that looks like an apocalypse of seeds in the cannabis colas.

Can You Grow Cannabis from Seeds You Find In Your Medical Bud?
If you live in a state that has legalized home-growing for personal use, you may be looking at those seeds and wondering if you should plant them? What would happen if you collected all the seeds and then tried to plant them?
Some seeds would germinate, and others would not. But when you are trying to cultivate seeds from a cannabis strain that has been prone to seedy weed, you would not want to grow plants that had the same properties. That would be lower quality cannabis. And you’d be stuck with more seeds. No one wants to reproduce a mediocre hybrid.
What Happens if You Smoke Cannabis With Seeds In It?
It’s cheap. Maybe you are thinking of just throwing it into the grinder and packing your bowl to see what happens? Well, unfortunately, when you incinerate seeds, you are changing the chemistry quite a lot. And while they can produce psychoactive and physiological effects (you will still get high), they can also produce some side-effects.
Both cannabis seeds and stems should be picked out and not consumed. They both contain cellulose, which burns at a hotter temperature than marijuana flowers. And that cellulose, when incinerated, produces carcinogenic toxins (cancer-causing). It makes the smoke hotter and harsher on your respiratory tract.
Some of the other side-effects that patients have experienced when smoking weed seeds are:
- Gastrointestinal and abdominal pain
- Sore Throat
Finally, if you do happen to roll some cannabis seeds in your cone, it’s going to freak you out a little bit—the seeds pop and crackle. Very loudly when you incinerate them, it’s kind of feels like taking a drag off a lit firecracker. No thanks!
What Do I Do With Cannabis Seeds If I Can’t Smoke Them?
Just because cannabis seeds are not ideal for smoking doesn’t mean that they will go to waste. There are other ways you can repurpose them after you separate or sift them from your bud.
Try placing stems and seeds on a baking tray in the oven for about 40 minutes to decarboxylate the cannabis. That activates it. Then, you can grind them up and use them to create a tea or a cannabis-infused butter. You can even add it to your flour if you want to bake some buzz-worthy edibles at home.
Another cool idea for seeds and stems is to add them (after decarboxylation) to a liqueur. You’ve seen vodka’s with hot peppers in the bottle, right? Same thing! You can place them into a bottle of vodka or whisky for a week and then filter them out. Repeat this process every week for a few months to build up the THC content in the alcohol.
