Female Cannabis Plant Producing Seeds

"Hermie" cannabis plants can look like normal female plants at first glance, but they produce pollen that causes seedy buds. Hermies are to be avoided!" New growers usually start from seeds. When a gardener decides to maintain an ongoing garden, the first step toward consistent results is to make a mother plant Learn about feminized seeds, or seeds that are bred to only produce female cannabis plants.

Do Feminized Cannabis Seeds Make Hermies?

What Are Feminized Cannabis Seeds? These seeds all grow up to be female plants. That means every plant produces buds. With “regular” or unfeminized seeds, about half the plants will turn out to be male, which don’t produce buds. They can also pollinate your female plants (causing seedy buds). Therefore most growers will remove male plants from the grow room as soon as they’re identified. Learn more about male vs female plants. Feminized seeds let you plan your grow more effectively because you don’t have to throw half the plants away once they start flowering.

Every plant grown from feminized seeds will produce the buds we know and love. This plant was grown from feminized Swiss Cheese seeds.

What Are Hermies? “Hermie” is short for “hermaphrodite.” Hermie cannabis plants usually look like normal female plants for the most part, but they also grow some male parts that produce pollen. This causes seedy buds just like pollen from male plants. Hermies are to be avoided! Read the full tutorial on hermies.

It’s no good if your “female” plants start growing male flowers or parts of male flowers. That can cause seedy buds just like a male plant!

This bud got completely seeded due to a hermie in the grow space. Notice the lumpy round bits. Those are seeds forming.

What’s the matter with a few seeds?

Cannabis growers are trying to grow sinsemilla (seedless buds). A few seeds won’t hurt anything. But if you have very seedy buds, it significantly lowers your yields because plants are putting all their energy into making seeds. The buds also tend to be less potent if they are full of seeds. Seeds are not the end of the world, but it’s good to avoid if possible.

“Sinsemilla” means “no seeds.” Sinsemilla is the highest quality and most potent of all buds

Since most growers are trying to grow sinsemilla, having only 100% female plants in the flowering grow room is crucial to prevent pollination.

Feminized cannabis seeds can be a blessing for small-scale growers. While male plants produce pollen sacs, feminized seeds ensure all your plants will end up being bud-bearing females (instead of growing half male and half female plants like with regular seeds).

If you don’t have room for extra plants, feminized seeds can make planning your grow a lot easier!

Good feminized seeds should produce only 100% female plants, with no hermies or male plants. So starting with feminized cannabis seeds lets you make the most efficient use of your grow space. You don’t have to worry about identifying male plants and throwing them away before they pollinate your female plants. With good feminized seeds, you know that if you’re growing 10 plants, all 10 of them will make buds, and that makes it easier to plan out your grow ahead of time.

With all these bonuses, why would any small-scale grower use any other type of seeds?

Pros of Feminized Cannabis Seeds

All plants produce buds

You don’t have to throw away half your plants after nurturing them for weeks

You don’t have to worry about your buds getting pollinated, causing seedy buds, reduced bud quality and lower yields

But is there a dark side to feminized cannabis seeds?

One of the biggest worries growers have about feminized seeds is that they will produce hermies instead of 100% female plants as advertised.

This hermie is growing both male and female flowers. Can this be caused by feminized seeds?

Unfortunately, hermies can be a lot easier to miss than a male plant since it may just be a small part of the plant that’s affected. A male plant makes itself known at the beginning of the flowering stage, but a hermie plant may grow only buds except for just one or two tiny pollen sacs. A few yellow hermie bananas hidden in the buds can also produce pollen. Any type of male flower part that grows in your garden can add seeds to your buds, and hermies are some of the worst offenders.

This grower didn’t notice that the buds had been seeded until harvest. As he was trimming, he noticed seeds popping out. Since there were no male plants, chances are this was caused by an unnoticed hermie somewhere in the grow space.

Is it True that Feminized Seeds Sometimes Cause Hermies? Yes!

Many growers believe that feminized seeds can cause hermies, and there is some truth to that. In order to create a feminized seed, one of the parent female plants had to be forced in some way to produce pollen.

That pollen is used to pollinate another female plant, and the offspring of those two plants will all be female since both of the parents were female. That’s how you get feminized cannabis seeds. But that also means every time you have a feminized seed, that seed had a plant that produced male flowers in its recent genetic history.

There are different ways to feminize seeds, but only some methods produce seeds that turn hermie on you.

It’s important to understand that hermies can happen a couple of different ways. And the different types of hermies affect what genes are being passed on to the seeds.

What Causes Hermies?

Hermies can be caused by many things, including…

bad genetics – the plant comes from a line of plants that naturally create hermies for no reason, even in good growing conditions

high stress – high temperatures, light leaks, inconsistent light schedules, as well as other types of major stress can cause a healthy plant to hermie, though some plants/strains are more susceptible than others

letting buds over-mature – this is also known as “rodelization;” basically when the plant’s buds have gone past maturity without being pollinated (if the grower waits way too long to harvest), a female plant may make male pollen within its buds as a last ditch effort to pollinate itself and make seeds for the next generation

chemical stimulation – by exposing a female plant to certain substances like colloidal silver or gibberellic acid during the early parts of the flowering stage, you can force any female plant to create pollen. This is how seedbanks get female pollen to produce feminized seeds.

Seeds created from “female” pollen will turn out being female (or at least as female as the parents).

The pollen from a hermie plant makes feminized seeds

The pollen sacs on this masculinized female plant have opened and pollen has spilled onto the leaf below

Another type of hermie: a yellow “banana” can appear in your buds and make pollen. This male flower part would normally be inside a pollen sac. When it’s in the open like this, it becomes a little pollen generator.

Feminized seeds are susceptible to becoming hermies themselves when exposed to the same conditions as their female “father” who produced the pollen. But since any plant can be chemically induced to produce pollen, it doesn’t mean that the ability to hermie in a natural environment is passed on to the seeds.

So only some feminized seeds come from parents with bad genetics, and that’s what’s the grower cares about most.

The bagseed gamble… When you find seeds in your buds, that usually means that the buds were pollinated by accident. Seeds that were accidentally created are suspect. It could be that a stray male plant caused them, which means there were no hermies and you will get about half male and half female plants. But accidental seeds could also be the result of herming by an indiscriminate grower, and that means you have feminized seeds, sort of. Some of them may produce pollen on you just like their parents. Growing with bagseed is a big gamble… you never know what you’re going to get.

Are your cannabis bagseeds viable? Viable, good seeds usually appear either dark and striped or solid gray/beige.

If a seed is pure white it usually means it’s underdeveloped and won’t sprout. But it can sometimes be hard to tell. In the end, if a seed sprouts and grows it’s a viable seed! I’ve had very pale, flimsy seeds sprout into gorgeous fast-growing plants, so if you’re not sure the best thing to do is try to germinate it!

Seed Banks & Breeders

Commercial breeders and seed banks use chemical stimulation to create feminized seeds. What that means is they put specific compounds on developing female plants to force them to produce pollen. You can actually do this yourself at home.

This technique works on nearly any female plant, including plants that would never hermie naturally. So it can be used to take two plants with great genetics to produce female seeds. But the same process will also work incredibly well on plants that do hermie easily all on their own. That means it’s up to the breeder to test and make sure that they have a solid plant with unbeatable genetics before using the feminization technique.

The pollen that results from chemical stimulation is used to pollinate another female plant and make feminized seeds. If the parent plants would never hermie without chemical stimulation, then you have created feminized seeds that won’t ever make pollen in your grow room.

But if one of the parent plants was chosen because it does hermie easily, you’ll end up with seeds that likely will herm. The breeder might not have done any testing on the parents or the resulting offspring to even know.

Without testing, a breeder can’t tell whether they’ve created quality feminized seeds

Choosing the Right Cannabis Breeder

Unfortunately, some cannabis seed breeders are more trustworthy than others. The great ones have created stabilized strains that have been bred over several generations to produce a consistent product without any problems with plant sex.

Less scrupulous breeders might breed two random female plants together and sell the resulting seeds as a new strain without any testing. In this second case, you don’t know what to expect, and neither does the breeder.

If the breeder hasn’t tested their strains extensively in many situations, they won’t know whether their seeds tend to hermie or not. If they have carelessly bred plants that have a tendency to herm, then it’s really likely that at least some of the resulting seeds will have the same problem.

Breeder choice is important!

I have to admit I may be biased towards feminized seeds. I’ve grown almost exclusively with feminized seeds over the last decade. It has made my life so much easier! I only purchase seeds from breeders that I trust and all the resulting seeds have been bud-bearing females. I haven’t had any real problems with hermies.

On the flip side, I’ve heard of growers buying feminized seeds from untrustworthy breeders and having a big portion of their seeds turn male or become hermies even in perfect growing conditions. So there is truth to the fact that you can run into hermie problems with feminized seeds.

Yet there are good and bad breeders out there, and with good breeders, you have a very low chance of running into cannabis sex problems.

So if you do choose to purchase feminized seeds (or any seeds really), please make sure you get them from a trusted breeder!

Conclusion: Feminized seeds from a trustworthy breeder have a low chance of producing hermies, but the odds are much worse with feminized seeds from an untrustworthy source

The truth is it takes a hermie of some sort to create feminized seeds. That means that you always run the risk of running into hermies when growing feminized seeds… yet that is true for non-feminized cannabis seeds, too! Lots of regular seeds produce hermies.

What’s most important, whether you get feminized seeds or not, is to get your seeds from a breeder who has a reputation for producing quality genetics. That is the best thing you can do for any strain to ensure a smooth grow. With a great breeder, you have a very low risk of running into any sex or gender problems.

I personally prefer feminized seeds, and that’s the only type of seed I grow. It makes it easier for me in my limited grow space. I haven’t run into any significant problems with hermies, so I’m satisfied with growing only bud-bearing plants.

Yet a lot of growers grow with regular seeds because they’re easier to breed and produce at home. Many growers have created a system for weeding out male plants that is more convenient for them than using feminized seeds.

In the end, when it comes to feminized cannabis seeds you need to decide whether the small chance for hermies is worth the convenience of all-female plants. It’s up to you to figure out what’s best for your needs!

Female Plant Producing Seeds

New growers usually start from seeds. When a gardener decides to maintain an ongoing garden, the first step toward consistent results is to make a mother plant or plants (this is covered in chapter 2). Once a quality mother is chosen, a gardener can propagate plants by taking cuttings for each successive garden. Since the cuttings or clones are identical to the mother, they are all females. The gardener can concentrate on getting the conditions and harvest time right for optimum results.

When I pick a female for a mother plant, I always choose something that I just adore to smoke, the type of marijuana that one hates to run out of. The thing is, sometimes pot thats great to smoke is a low yielder or takes too long to finish. That’s when the breeder’s creative energy can put a magic touch on the cannabis plants.

Gardeners also decide to try breeding when seeking a more ideal high and flavor. Whether the goal is enhanced qualities of the high or improved growing characteristics, breeding takes time, space and patience.

In order to reproduce an already-great female, all you need is a mother to clone from, but in order to breed you need a few good males, too. Actually, one male can be sufficient to pollinate hundreds of females.

In my opinion, the best way to breed is to start out working with quality genetics. Then you can enjoy the experimental nature of the whole thing. Breeding is an exercise in imagination. Start off with something you like and then think about what would make the plant better to grow or smoke.

It is necessary to start with plants that have already exhibited different desirable qualities. For instance, maybe one variety has a terrific flavor and high but is a finicky grower or takes a long time to finish. Another variety might be a hardy plant and finish quickly, but the high isn’t as mentally stimulating or the flavor isnt as tasty as it could be.

Once the gardener decides which plants have traits that would make a good combination, one variety becomes the donor parent (male) and one the recipient parent (female). These two parents are known as the PI generation.

The female is the plant whose traits you like but want to improve. The male is used to add traits to the female in order to improve a certain characteristic, such as finishing time. In other words, the male is used to “donate” new characteristics to the female.

The best way to identify a good male candidate is to experience a female from the same strain. After a suitable strain is identified, the most vigorous male is chosen. Sometimes it can be difficult to get a male plant of the variety you want. It may require obtaining additional seeds of the variety. If you think you might undertake any breeding, this is one reason to preserve seeds or possibly even males from the varieties you are working with.

When different varieties are crossed, the resulting plants are hybrids; that is, they are a genetic mix of the two parents or PI plants. This cross is the F1 generation. When grown out, the Fl’s have only subtle variations. Significant variety in this generation probably means that the parents were not completely stabilized strains. The F1 generation is like a big family of siblings. They are similar but none are precisely the same. They will exhibit slightly different combinations of their parents’ characteristics, but will still be more alike than they are different.

The first time you cross two different kinds of cannabis together, you get a phenomenon that’s called “hybrid vigor.” F1 plants often exhibit impressive vitality. When F1 plants are made into mothers, their clones possess a near super strength.

It is now possible to go in two directions with the F1 generation. If the desired characteristic is present, the best F1 males are selected and crossed back to the female parent or clones taken from this parent. This is called backcrossing. Usually breeders backcross a number of times to introduce a desirable characteristic to a strain. Eventually, successful backcrossing results in a stable strain.

The other possibility is to cross F1 males and females with each other. Plants grown from the seeds of this cross are called the F2 generation. Whereas the F1 s were fairly uniform, the F2s are heterogenous. This cross increases diversity. The plants will exhibit a wider range of characteristics from which to select.

I basically get three dominant phenotypes and one recessive phenotype in the typical F2 generation. One plant will be like the father, one like the mother, one a combination of both and one a recessive phenotype that may exhibit some non-dominant genetic traits.

Selection is key in winning breeding programs. The hallmark of selection lies in the human ability to choose the best from a cluster of many. Selection is pardy talent and partly understanding the plants. It necessitates that the breeder knows what to look for and also knows his or her plants and their needs.

Selecting Winning Plants

Cannabis breeding allows a gardener to come up with an endless number of combinations.

When I choose strains I always select for medical potency first, yield and finishing time second. When assessing cannabis plants, I look for a few main things: the length of stem between nodes, the profuseness of THC trichomes, the finishing time, the aroma, and last but certainly not least, the effect.

It is desirable for the nodes to grow close together. Nodes are the places where branches come off of the main stem. Internodes is the term for the space between the branches. The less stem between branches, the better. Of course, THC glands are best when they are found in massive clusters rather than sparsely distributed. Most people prefer short finishing times. When growing outdoors, the finishing time is especially important and should be suitable to the region. Aroma and effect are more subjective. Some people like fruity, some pine. Whatever the desire, both aroma and effect will be enhanced

by using organic methods of cultivation and by harvesting and curing properly.

The first thing I typically notice about a new variety is the shape of the leaf and the tone of green it has. Even before harvesting any buds, I can tell by the shape of the leaf if it is going to be special. Flowering out strains is the ultimate way of knowing the full range of a strains qualities. Most strains take 3-4 months to finish a complete cycle, so seeing how each strain grows takes a good amount of time and space. Once you get to know your plants you can organize your garden by grouping plants according to height or similar harvest time. This can be quite helpful for cross-pollination projects that use many different females and one choice male.

It is usually trickier to select a desirable male than it is to choose a female you want to cross. This is a good reason to select several males and cross each of them with the female variety that you like, and then see which produces the most promising hybrids.

Breeding with NYC Diesel

NYC Diesel is a blend of a Mexican sativa and an Afghani. It tastes like ripe red grapefruits. Everyone I smoke it with loves it, so I thought it would be a great male.

I planted several Diesel seeds and got three males, each one showing a slightly different growth habit. I’d read that it was possible to achieve greater genetic depth by breeding with more than one type of male from the same genetic pool.

With this new information, I conducted a little genetic experiment. I placed fifteen different varieties of female plants in my grow room and crossed them to two of the male NYC Diesel’s. One of the males had closer internodes and wider leaves, and the other had more stretch between nodes and thinner leaves. I put both of these males in the room with the females, and as the pollen flew, the two of them pollinated all the plants.

I liked the results. While all the crosses had NYC Diesel genetics, i had greater variety from which to make my selections.

When deciding what to breed for, another factor to consider might be what other people want. For instance, many outdoor growers are looking for a fast finishing strain. For some growers, fast finishing strains may be desirable even though they are often less potent. Medicinal users may also be looking for specific characteristics in a strains effect.

How to Cross

Having enough space to breed is important. When working with cannabis you may have to produce hundreds of plants before you discover the winner you have been looking for, so patience is a virtue. The more plants you are able to grow out and select from, the more likely you will find something unique or precisely to your liking.

I put the females under 12/12 lighting a week before the males are added. This gives the female plants a head start, so they have more time to produce flowers. Also, after harvest when all the seeds have been removed, the leftover material makes excellent water hash.

It takes the male cannabis plant about 3 weeks to start throwing pollen. It continues for about 3 weeks. Female calyxes that are the first to get hit make the first seeds. The females continue to make new calyxes. As they become ripe, the male pollen touches them and seeds start to form. The last calyxes to get pollinated usually don’t get a chance to finish, and the seeds come out white.

In my quest for the best medicinal genetics, I am constantly trying new techniques and genetics, constantly learning about this sacred plant and all the gifts she holds. Spreading quality seeds around the world has brought me many new friends and adventures, and I truly think that it changes not only the topography of planet Earth, but her soul as well.

For so many years, I grew only seedless ganja because it smokes the best, but sometimes I have daydreams about what would happen if every ganja smoker grew one seed crop and spread them around

The Soma Way of Female Seeds

Making cannabis seeds is an art. As in any art, there are different methods of application. I have tried using gibberilic acid, pH stress, light stress, and fertilizer stress to force my female plants to make seeds. All of these methods are harsh on the plants, and some, such as gibberilic acid, are not organic.

In my search for cleaner, more earth-friendly ways of working with the cannabis plant, I have found a new way to make feminized seeds. This method of making female seeds is Age Feminization Technique (AFT). I like to call it “Rodelization,” after a friend who helped me realize and make use of this way of making female seeds.

Stressing for Seeds

Female seeds happen from stress, not genetics. That’s right. I am saying that all cannabis varieties have the capability of making male flowers on 100% female plants. Stress is the cause of this phenomenon. In the 32 years I have been actively growing cannabis, I have come to know every form of stress a cannabis plant can experience.

It takes many harvests before you really get to know a type of weed. Just like getting to know human friends, it takes time. Some strains prefer a higher pH, some a lower one. Some like a lot of food some like much less. There is quite a lot of variety in marijuana genetics, and you cant treat every plant the same way.

I have grown the same strains now for close to a decade, and am truly getting to know every bit of body language that my plants exhibit. I can recognize them now from a distance.

After growing crop after crop of the same plants in the same conditions, I noticed that if I flowered the plants 10-14 days

First, match the female plant with the pollen from the same female in the previous crop. Turn off all of the fans in the room. With a fine watercolor brush, remove some pollen from the bag and paint it on the female flower. This is repeated for each variety. I have done this successfully with up to ten strains in the same room.

I pollinate the lower flowers, leaving the top colas seedless for smoking. This method requires two crops to produce seeds, but it is completely organic. It also lets you have great quality smoke at the same time and from the same plant you are using to make female seeds. If you have never grown seeds for fear of not having something good to smoke, you will love this method.

You can also use the collected pollen to make new female crosses by cross-pollinating. This is a great solution when you want to use a variety you like as the “male” part of the cross, but you don’t have access to seeds or males.

The second way is less controlled, or may be used when you are gardening a single variety. Rather than drying and saving the pollen, the females with male flowers are brought directly into the room with a second group of females that are 3 weeks into the flowering cycle. The circulation fans are turned to high and the little particles of pollen circulate around the room for several days. Six to seven weeks later you have ripe 100% feminized seeds. This method does not produce as many seeds as crossing with a genetically male plant, but it is productive enough to keep a variety in circulation.

Feminizing methods can be extremely valuable in the effort to preserve strains, as well as being useful for any breeding program. Having been a farmer who moved my genetics far away from where they started, I know the value of seeds. My friend Adam from TH Seeds in Amsterdam has a motto that I love to borrow: “Drop seeds not bombs.”

Feminized seeds

Feminized seeds are bred to produce only female plants, as opposed to regular seeds that have a 50% chance of producing male plants.

More about feminized cannabis seeds

Feminized cannabis seeds are important to cannabis cultivation because only female plants produce consumable flowers.

Beyond the fact that male cannabis plants produce pollen sacs instead of flowers, having males plants around female plants can ruin an entire harvest. That’s because male plants pollinate the buds of young female plants. When that happens, the flowers will be full of seeds, lowering their quality and value.

Breeders and growers developed feminized cannabis seeds to address these challenges. By increasing the likelihood that all your seeds will produce female plants, you eliminate the possibility of getting a male plant that won’t produce flowers and of having a male plant accidentally pollinate flower-bearing female plants.

How to get feminized seeds

Feminized cannabis seeds are very mainstream. You can buy feminized cannabis seeds online from seed banks around the world. And if you live in a place where home cultivation is legal, you should be able to purchase feminized seeds at most dispensaries. You can also feminize seeds on your own, but to get the best feminized seeds, buy them from a reputable breeder or seed bank.

How are marijuana seeds feminized?

Feminized cannabis seeds are created through a process of genetic manipulation. Essentially, the idea is to induce female plants to make pollen. Normally, only male plants produce pollen, but if you can somehow make a female plant produce pollen, then what you’ve got is pollen containing only female chromosomes. There are a few ways to make this happen:

  • Spray a female plant with colloidal silver while it grows and transitions into the flowering phase. This chemical promotes the growth of pollen sacs, and because this pollen comes from a female plant it carries female chromosomes. After the plant starts producing pollen, use it to pollinate the flowers on a regular female cannabis plant. These pollinated flowers will produce feminized seeds. There are some reports online that say you shouldn’t smoke or otherwise consume any part of a plant that’s been sprayed with colloidal silver. And there are also reports saying that’s baloney. You’ll need to decide for yourself.
  • In a process very similar to the colloidal silver method, spray a young female cannabis plant with silver thiosulfate. This chemical suppresses the production of ethylene, which is necessary to the flowering process. By feeding your female plant silver thiosulfate, you encourage the plant to produce pollen, which can be used to pollinate other female plants and produce feminized cannabis seeds.
  • The third main method is known as “rodelization.” This is an all-natural technique, although it does not produce the desired outcome as consistently as the colloidal silver or silver thiosulfate methods. Rodelization takes advantage of a natural process in which an unpollinated female plant will sometimes organically sprout its own pollen sacs. Think of it as the plant’s last-ditch effort to reproduce. In this method, you force a female plant to remain in the flowering phase for so long that the plant’s self-pollination mechanism kicks in. When this happens, you can use the pollen created by the female plant to pollinate the flowers on a regular female plant, which will then produce feminized seeds.

What is the difference between autoflowering and feminized seeds?

Autoflowering seeds have been bred to move into the flowering phase without needing changes in light to activate the production of flowers. Whether cannabis seeds are seeds doesn’t have anything to do with when plants enter the flowering phase. Feminized cannabis seeds have been bred to grow only female plants.

Are feminized seeds guaranteed to be female?

While feminized seeds generally grow only female plants, there is no 100% guarantee whether you buy feminized seeds or create them yourself. Every once in a while, a feminized seed will still grow up to become a male plant. For this reason, it’s a good idea to keep a close eye on your plants as they mature. If you ever see pollen sacs starting to form, remove the plant before it accidentally pollinates and ruins your female plants.

Do feminized seeds produce seeds?

Theoretically, plants sprouted from feminized seeds should not produce seeds. They should only grow into female plants, and unpollinated female plants produce buds instead of seeds. Cannabis plants make seeds when the flowers of a female plant are pollinated with the pollen from a male plant. In the absence of male plants, there should be no pollen and therefore no seed production. If you force a female plant to stay in the flowering stage too long, however, all bets are off and you could wind up with rodelization as discussed above.

Are regular seeds better than feminized?

Growing cannabis is all about your goals and preferences. There is no inherent reason why regular female marijuana seeds would be considered better than feminized seeds. With that said, feminized seeds:

  • Maximize yields by reducing the chance of producing an unusable male plant
  • Decrease the risk that a male plant will accidentally pollinate female plants
  • Simplify the growing process by making unexpected male plants much less likely

In many ways, feminized seeds can be a good option for new growers, as they eliminate some guesswork and reduce the pressure to quickly and accurately identify and eradicate unwanted male plants. However, there are no guarantees and new growers should still do their homework and know how to spot a male cannabis plant.

Tips for growing marijuana from feminized seeds

The steps for growing cannabis from feminized seeds are the same as growing from regular seeds. If you understand the laws and regulations where you live and want to give cannabis cultivation a try, keep these things in mind.

Before you plant the first seed, you’ll need to make some decisions:

  • Do you want to grow your cannabis indoors, in a greenhouse, or outside under the sun? do you plan to cultivate?
  • Will it be autoflowering or photoperiod?
  • Are you going to grow from seed or clone a cannabis plant?
  • What cultivation medium will you use? Good old soil, hydroponic solution, or an aeroponic system?

Each of these areas may generate more questions. If you grow indoors will you use natural or artificial light? If you go hydroponic, will you also use a grow medium like rockwool or hydroton? While you could just buy a clone, plop it in some soil, and hope, it’s best to think like a beginner and do some thorough research before taking the marijuana-growing plunge.

On the other hand, if that’s just not your style, you could treat cannabis like a houseplant and attempt a simple indoor grow with natural light. If you start with a plant or two on a sunny windowsill and wind up with a nice harvest, you might choose to move on to a more complicated setup or just keep it simple. Like most things in the cannabis world, it’s all up to your personal taste and how much effort you want to put into it.
