Marijuana Cultivation/Producing Seeds

Sooner or later every grower is going to want to produce marijuana seeds. Developing a new stable strain is beyond the scope of this discussion and requires the ability to grow hundreds or even thousands of breeding plants. However, just about any grower can manage to preserve some genetics by growing f2 seeds where they have crossed a male and female of the same strain, or can produce a simple cross which would be referred to as strain1xstrain2 for instance white widow crossed with ak-47 would be referred to as a WW x AK-47. You can produce some excellent seed and excellent marijuana this way.

To Feminise or not to Feminise Edit

There are numerous myths surrounding feminized seeds. Feminizing seeds are a bit more work than simply crossing two plants naturally. However it will save you a lot of time in the end. If you make fem seeds properly then there is no increased chance of hermaphrodites and all seeds will be female. This means no wasted time and effort growing males and it means that all your viable seeds produce useful plants. Since roughly half of normal seeds are male this effectively doubles the number of seeds you have.

Feminized seeds are bred to contain no male chromosomes, which will be able to produce the crop of resinous buds sought by most growers. For gardeners who require a quick and easy cultivation process, feminized seeds are the ideal choice. Some medicinal cannabis users may be deterred from growing their own supply because of the perceived difficulty of growing or of identifying the different genders and removing males early in the blooming period. Feminized seed-strains offer a simple solution to these issues, as there is no need to spend time in the first weeks of flowering checking for male plants.

Other times you will have no choice but to produce feminized seed because it will be a female plants genetics that you want to preserve and you won’t have any males. Perhaps you received these genetics via clone or didn’t keep males.

The new thing on the market for commercial Cannabis cultivation are auto-flowering feminized strains. By crossing of the cannabis ruderalis with Sativa and Indica strains many cultivators have created interesting hybrids which boast benefits from both sides of these families.

The first ‘auto-flowering cannabis seed’ which came on the market a few years ago was the Lowryder #1. This was a hybrid between a Cannabis ruderalis, a William’s Wonder and a Northern Lights #2. This strain was marketed by ‘The Joint Doctor’ and was honestly speaking not very impressive. The genetics of the ruderalis was still highly present which caused for a very low yield and little psychoactive effect. Not very attractive.

Auto-flowering cannabis and the easily distributed seed have opened a whole new market in the world of the online grow-shop, making it easy for home growers with shortage of space to grow rewarding cannabis plants in many different varieties. To grow plants indoors, a growing medium (e.g. soil or growing Potting soil, irrigation (water), fertilizer (nutrients), light and atmosphere need to be supplied to the plant.

Auto-flowers have been rising in popularity fast and there are now auto flower growers communities. These Web properties allow users to get information on how to grow these non photo-sensitive plants and what are the best practices when producing and germinating auto-flower seeds.

Selecting Suitable Parents Edit

There are a number of important characteristics when selecting parents. First are you making fem seeds? If you are then both parents will be female. This makes things easier. If not then the best you can do is select a male with characteristics in common with the females you hope to achieve from the seed.

Obviously potency, yield, and psychoactive effects are critical to the selection process. But some other important traits are size, odor, taste, resistance to mold and contaminants, early finishing and consistency.

Collecting and Storing Pollen Edit

In order to collect pollen you simply put down newspaper around the base of the plant. The pollen will fall from the plant onto the newspaper. You can then put this newspaper into a plastic bag and store it in the refrigerator or freeze it. Pollen will keep for a few months in the refrigerator and can be used on the next crop. Filtering the pollen through a silkscreen, drying, and freezing can extend viability for decades. At least one reader indicates success using pollen treated in this manner and stored at -30 c for 17 years. The chance of viability does decrease with time, even in the freezer, so the more fresh the pollen the better. Wrapping the pollen in a layer of aluminum foil and then a layer of plastic should help to protect it from freezer burn. Additionally, oxygen evacuation such as with a heavy gas like nitrogen or vacuum sealing should provide additional assurance of preservation.

Pollinating a Plant Edit

To pollinate a plant you can brush the pollen on a flower with a cotton swab or you can take the plastic bag, then wrap the flower inside it and shake, trapping the pollen inside for easier transportation. In this way you can selectively pollinate plants and even individual buds and branches.

Male Isolation Edit

A male plant or a plant with male flowers will pollinate your entire crop rendering it seedy. You probably don’t want THAT many seeds so how can you avoid it? Moving the male to another room might work but if that other room shares an air path via ducting or air conditioning then pollen may still find its way. One technique is to construct a male isolation chamber.

A male isolation chamber is simply a transparent container such as a large plastic storage tub turned on its side (available at your local megamart). Get a good sized PC fan that can be powered with pretty much any 12v wall adapter, by splicing together the + (yellow or red on fan, usually dotted on power adapter) and the – wires (black on fan, usually dotted power adapter) just twist with the like wire on the other device and then seal up the connection with electric tape. Then take a filtrate filter and cut out squares that fit the back of the pc fan so that the fan pulls (rather than pushes) air through the filter. Tape several layers of filter to the back of the pc fan so all the air goes through the filter. Now cut a large hole in the top of the plastic container and mount the pc fan over top of it so it pulls air out the box. You can use silicon sealant, latex, whatever you’ve got that gives a good tight seal.

This can be used as is, or you can cut a small intake in the bottom to improve airflow. Pollen won’t be able to escape the intake as long as the fan is moving but you might put filter paper over the intake to protect against fan failures. You can also use grommets to seal holes and run tubing into the chamber in order to water hydroponically from a reservoir outside the chamber. Otherwise you will need to remove the whole chamber to a safe location in order to water the plant or maintain a reservoir kept inside the chamber.

Making Feminized Seed Edit

To make feminized seed you must induce male flowers in a female plant. There is all sorts of information on the Internet about doing this with light stress (light interruptions during flowering) and other forms of stress. The best of the stress techniques is to simply keep the plant in the flowering stage well past ripeness and it will produce a flower (with seed).

Stress techniques will work but whatever genetic weakness caused the plants to produce a male flower under stress will be carried on to the seeds. This means the resulting seeds have a known tendency to produce hermaphrodites. Fortunately, environmental stress is not the only way to produce male flowers in a female plant.

The ideal way to produce feminized seed through hormonal alteration of the plant. By adding or inhibiting plant hormones you can cause the plant to produce male flowers. Because you did not select a plant that produces male flowers under stress there is no genetic predisposition to hermaphroditism in the seed vs plants bred between a male and female parent. There are actually a few ways to do this, the easiest I will list here.

Colloidal Silver (CS) Edit

This is the least expensive and most privacy conscious way to produce fem seed. CS has gotten a bad name because there is so much bad information spread around about its production and concentrations. It doesn’t help that there are those who believe in drinking low concentration colloidal silver for good health and there is information mixed in about how to produce that low concentration food grade product. Follow the information here and you will consistently produce effective CS and know how to apply it to get consistent results.

Simply construct a generator using a 9-12 v power supply (DC output, if it says AC then its no good) that can deliver at least 250ma (most wall wart type power supplies work, batteries are not recommended since their output varies over time). The supply will have a positive and negative lead, attach silver to each lead (contrary to Internet rumors, you aren’t drinking this so cheap 925(92.5%) Stirling silver is more than pure enough. You can expose the leads by clipping off the round plug at the end and splitting the wires, one will be positive and the other negative just like any old battery. Submerge both leads about 2-3 inches apart in a glass of distilled water (roughly 8 oz). Let this run for 8-24 hrs (until the liquid reads 12-15 ppm) and when you return the liquid will be a purple or silver hue and there may be some precipitate on the bottom.

This liquid is called colloidal silver. It is nothing more or less than fine particles of silver suspended in water so it is a completely natural solution. It is safe to handle without any special precautions. [ citation needed ] The silver inhibits female flowering hormones in cannabis and so the result is that male flowering hormone dominates and male flowers are produced.

To use the silver, spray on a plant or branch three days prior to switching the lights to 12/12 and continue spraying every three days until you see the first male flowers. Repeated applications after the first flowers appear may result in more male flowers and therefore more pollen. As the plant matures it will produce pollen that can be collected and used to pollinate any female flower (including flowers on the same plant).

Silver Thiosulfate (STS) Edit

Silver Thiosulfate is a substance that has similar principle, application and results of CS, but is more difficult to make. STS is more difficult to acquire, but it can still be obtained directly from a chemical supply company. STS is not an expensive or controlled substance.

Gibberellic Acid (GA3) Edit

This is probably the most popular way to produce feminized seed, but at the same time the least effective. GA3 is a plant hormone that also causes the plant to stretch uncontrollably. It can be purchased readily in powdered form, a quick search reveals numerous sources on e-bay for as little as $15. Simply add to water to reach 100ppm concentration and spray the plant daily for 10 days during flowering and male flowers will be produced.

Cannabis in the Stone Age, the origins of breeding

We know that the history of cannabis goes back for millennia, but when and where was it first domesticated? Today we travel back in time to the Stone Age to find out and see how cannabis has been at the side of humanity since the beginning of agriculture itself, something that our ancestors knew how to take advantage of!

20 paintings from the Golden Age of stoner art

Ever since tobacco landed in Europe from America, brought by the Spanish conquistadors, its fusion with cannabis was a logical response to society’s craving for the more recreational side of life, in a world that was escaping the dark Middle Ages to enter the joy and abundance of the modern period. And this was all captured by the painters of the time, with special emphasis on the exponents of the so-called Golden Age of Dutch Baroque painting, of which today we bring you some examples that show that smoking cannabis in a pipe was already fashionable much earlier than you might have imagined.

Cannabis gifts for your stoner friend or partner

Finding a good present to give is not always an easy task, although if the person we want to give a gift to is a cannabis lover, things will be a little easier. Today we want to inspire you and give you some ideas for choosing the ideal gift so you hit the spot the first time.

Salaries in the cannabis industry

Despite the unemployment crisis caused by the Covid pandemic, job opportunities in the cannabis industry have been steadily increasing. With many sectors still struggling to make ends meet economically, the weed industry continues to soar like a rocket, and that is reflected in the salaries earned by its professionals. Do you know how much a cannabis dispensary employee earns per hour? Or what is the annual salary of a director of operations of a commercial greenhouse? And the wages for a trimmer? We will try to answer these questions by looking at the US, the world’s largest cannabis market, so everything that happens there serves as a mirror for what one day, hopefully not too far away, may happen here.

How to grow feminized seeds indoors

Do you want to know how to grow feminized seeds indoors? These tips from Dutch Passion will help you grow the best feminized seeds indoors. More information can be found in our extensive indoor growing guide.

Choose a grow system that you can understand

Deep water culture may be one of the best ways to grow feminized seeds indoors, but it requires a good working knowledge of nutrient management, nutrient measurement and plenty of experience. Growing cannabis in coco fibre is easier and produces heavy crops. Many first time cannabis growers start growing with a soil mix bought from the local grow shop. Once you have grown a few crops your confidence will improve and you will understand the basics, and feel able to tackle more complicated grow systems. Keep your first cannabis grows as simple as you can, and use the local grow shop for advice. Your local hydroponics store is a one-stop shop for materials and advice.

Choosing feminized seeds for indoor growing

It’s never been easier to buy feminized seeds online. Although you have hundreds of varieties to choose from, your first decision is whether to buy feminized autoflower seeds or feminized photoperiod seeds.

Growing feminized autoflower seeds indoors

Feminized autoflower seeds grow from seed to harvest with 20 hours of daily light, taking around 75 days. First time cannabis growers are often recommended to grow feminized autoflower seeds, they are easy to grow and the best autoflower seeds can produce huge yields of several hundred grams per plant in good conditions. The Dutch Passion feminized autoflower seed collection is one of the best available, with lots of customer grow reviews.

Growing feminized photoperiod seeds indoors

Feminized photoperiod seeds are often simply called feminized seeds. They have two growth phases controlled by the amount of light. When growing feminized seeds indoors under 18+ hours of daily light they grow in a vegetive mode, producing leaves, roots, branches but no buds. When the amount of daily light is reduced to 12 hours the plants start to produce buds, this is known as the bloom phase, sometimes called the flowering phase. Depending on the variety, the bloom phase takes around 9 weeks of 12/12 light. One of the best tips for growing feminized seeds indoors is to provide plenty of light during bloom to maximise your harvest. For a 1.2 x 1.2m tent a 600W HPS is a good solution, and some growers will use higher light levels to maximise their harvest.

Feminized seeds indoors. Avoid over-feeding and over-watering

When growing feminized seeds indoors the two main mistakes we see are plants being over fed, and (for soil grown plants) over-watering is a common error. Cannabis roots need oxygen to thrive, they don’t like waterlogged soil. Allow the soil to partially dry out between waterings, this allows some root aeration. Over feeding plants can really slow down development, the tips of the leaves go brown and crispy – a condition known as nutrient burn. Experienced growers monitor their nutrient concentrations using an EC meter to measure Electrical Conductivity, they are a recommended grow room gadget to help optimise your grows. Over-feeding your cannabis plants is particularly damaging to young plants which can remain permanently stunted, never fully recovering afterwards. When growing feminized seeds indoors, start your plants at low nutrient concentrations and gradually increase nutrient concentration, backing off at the first sign of over feeding.

Feminized seeds indoors. Maintaining the nutrient sweet spot

The experienced cannabis grower is able to steadily increase nutrient concentrations throughout the grow without under-feeding or over-feeding his plants. Keeping your plants in this nutrient sweet spot will ensure that you feminized seeds grow into healthy, heavy yielding plants. If light levels are high, the root mass is healthy and plenty of fresh air is supplied to the grow room then you should get healthy plants with heavy blooms.

The best nutrients for feminized seed indoor growing

All of the major nutrient companies offer products that will grow good quality cannabis. Many growers will eventually settle on their own preferred nutrient brand and feel that using the same brand with increased skill and experience is the best approach.

High THC results with feminized seeds grown indoors

Combine good quality cannabis genetics with an optimised environment and you will get heavy harvests of THC rich buds. The latest research is showing that crops grown under high intensity LED grow lights have routinely higher THC levels compared to identical cuttings grown under HPS. Use of UVA and UVB supplemental light, such as the SolarSystem UVB during bloom can also increase THC levels. A selection of the best LED grow lights on the market can be found on our sister companies website, Crazy LEDs. As well as offering higher cannabinoid levels, LED grow lights produce less heat than HPS lights, use less energy and last longer. LED grow lights are the preferred choice of the serious hobby grower as well as the professional legal cannabis producers.
