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.

Get Started Growing Feminized Cannabis Seed

Growing your own cannabis for personal use is a rewarding practice—as well as a great way to save money. Today there are quite a few options open to home growers, and cultivating high-quality cannabis is easier to accomplish than ever before.

Commercial growers rely on clones for their mass production, and seed plays a much smaller role, mostly for breeding to create new strains. Growing numerous seeds from a new cross or true strain and selecting the best phenotypes, which are then cloned for large production, is the goal of these companies. For the majority of home growers, however, the opposite is true, and clones play a smaller role. Although cloning is done in home grows, seed reigns supreme!

Most seed companies present a few options for seed buyers: normal seed, auto-flowering seed, and feminized seed. For home cultivators—particularly beginners—feminized seed is a great choice.

What Is Feminized Seed?

Simply stated, feminized seed is seed that will only grow into female plants, which is the goal of nearly every home grower. Female plants, of course, are the sex that grows the lush, sticky, trichome-covered flowers that the grower will harvest and use for medical purposes or recreational enjoyment.

For seed companies to create feminized seed, the process is fairly straightforward. The fact that plants will reproduce when under stress is widely known. In fact, when some female cannabis plants are in full flower but not in the presence of a male cannabis plant, they will resort to self-pollenization by producing a very small number (sometimes only one or two) of male sex organs, which they then use to pollinate themselves to create seed and ensure future generations of their kind.

Known as hermaphrodites, these aberrant female plants with minor male traits are sometimes difficult to detect in a grow with other females. Usually, these “hermies” are an undesirable thing, but since they can be difficult to detect in a large grow, they slip by undetected when harvested, producing good flowers, but flower that also contains a very small number of seeds, usually just a few.

When a cannabis enthusiast discovers a seed or two in an otherwise excellent bag of cannabis flowers, the seeds are a result of a self-pollinating female plant. When germinated and grown, these “selfed seeds” will invariably grow into female plants, because the female that pollinated herself lacks the male chromosome to produce a true male plant. By reproducing herself without being pollinated by a true male, the best she can do is create more females just like herself. For this reason, “bag seed” often grows into plants that produce surprisingly good flower, although these plants also have the tendency to self-reproduce once mature—just like their mother.

How Is Feminized Seed Made?

True feminized seeds sold by seed companies are created intentionally by using select female plants. Feminized seed is not true self-pollinated seed, but is quite similar, created by using more than one female plant.

To create this seed, seed companies will select prime females of the same strain. These females are the best phenotypes of that strain—the best of the best. They’re the stickiest and hardiest females, the ones that have amazing terpene profiles and rich, tantalizing aromas. One of these select females is then stressed to encourage hermaphrodite traits.

There is more than one way to intentionally stress a female plant, but probably the most common method is to apply colloidal silver to the female. Exposing her to colloidal silver will cause the female to produce a fairly robust amount of male sex organs—the pollen sacks seen on pure male plants. The cultivator then collects an ample quantity of this feminized pollen, which is the consistency of fine dust. Dusted or brushed onto the flowers of other prime females of the same strain will result in an abundant amount of feminized seed of that particular strain.

6 golden rules for growing feminised seeds

Feminised cannabis seeds hit the market more than fifteen years ago and gradually conquered it. Even the growers that were reluctant at first have given in to the qualities of these genetics, which allow the size of the crop to be calculated from the start without having to germinate more seeds than the strictly necessary. In fact, with the certainty that they will all grow into female plants, sexing becomes superfluous, which has contributed to their exponentially increasing popularity in recent years.

If you want to make the most of our best feminised seeds this season, here are six Golden rules to help you get the perfect crop. Ready? Let’s get down to it.

1. Too much care: if you are taking your first steps in cannabis cultivation, you might fall into the trap of paying them too much attention. What do we mean by that? Well, observing your plants and understanding their needs is good for them, actually it is crucial for a successful crop. That said, a common rookie mistake is believing that if you give them tones of nutrients, for instance, they will grow more vigorously. This normally leads to overfeeding, plant stress or overwatering. So just relax, learn to understand your plants and give them what they need, nothing more.

2. Underwatering: try to keep humidity under control but without the plant showing obvious symptoms of thirst. If your cannabis plants get too dry during the early growth stages, they will develop further problems later on, particularly at the roots.

3. Overwatering: avoid flooding the plants with excessive, too frequent watering and allow time for the plant to “breath” between waterings. Overwatering and overfeeding the crop is not a good idea; more marijuana plants are lost to overprotection and excessive attention than to a bit of procrastination.

4. Space planning: cannabis plants grow vigorously, so even if they are smaller at first, keep in mind that you will have to arrange them according to the size they will be once the vegetative stage is over. Otherwise, the plants will be too close to one another and the crop density will be too high, which might lead to lack of aeration and contribute to the development of fungus.

5. Nitrogen: nitrogen is essential for the growth and natural development of plants, so make sure it is always available.

6. Prevention: the golden rule to stop insect and fungus pests from colonising your cannabis crop is PREVENTION. Once they set a foothold, some plagues such as spider mite, thrips and whiteflies are hard to eradicate, let alone fungus such as powdery mildew and Bortrytis, which can well ruin your whole crop. That said, there are organic methods and preventive measures you can use to beat these uninvited guests and stop them from colonising your cannabis crop. Have a good harvest!
