First Feminised Seeds Company Since The 1990’s

Dutch Passion were the first company in the world to create feminised cannabis seeds back in the 1990’s. Feminised seeds changed the way people grew cannabis as the grower can use a smaller grow room with fewer seeds for each grow. Each feminised seed will eventually grow into a mature female plant. Feminised seeds account for the vast majority of cannabis seeds used, these days over 95% of all cannabis seeds are feminised.

The process to create feminised seeds was discovered in the 1990’s when Dutch Passion allowed some female cannabis plants to bloom for many weeks longer than normal, just to see what happened. The plants eventually produced male flowers, the pollen was collected from these. To everyone’s great surprise this (‘female’) pollen produced seeds which only gave rise to female plants. Today, different techniques are used to produce and collect this ‘female pollen’. Feminised cannabis seeds have made growing your own cannabis easier than ever before.

Since the invention of feminised seeds, we have continued to improve feminised seed performance and results. Dutch Passion’s main focus is to provide the best performing cannabis seeds to professional growers and home growers. We source the finest cannabis genetics from our unrivalled network of breeders and genetic specialists around the world. When you buy your next feminised seeds buy them from Dutch Passion, the original creators and masters of feminised seeds.

What Are Feminized Cannabis Seeds ?

Around 95% of feminised cannabis seeds grow into mature photoperiod female cannabis plants. Before feminised seeds were invented people grew from regular cannabis seeds which produced roughly equal numbers of male and female plants. Growers are usually only interested in the buds which grow on the female plants, male cannabis plants are normally discarded.

When Dutch Passion first created feminised seeds back in the 1990’s it was a revolution for growers who could grow their weed easily with fewer seeds, fewer plants, smaller grow rooms and less energy. Feminised seeds have remained popular with the majority of growers ever since.

Feminized vs Autoflowering Seeds

Feminised seeds have 2 main phases to their lives, veg and bloom, these can be controlled by the grower. During the first ‘veg’ stage of their life, feminised seeds grow vegetatively. During ‘veg’ growth (usually under 18-24 hours of daily light) plants grow leaves, roots and branches but no buds. Buds start to appear when daily light hours are reduced to 12/12 light which induces bloom (flowering). This requires around 12 hours of darkness and 12 hours of light per day.

Autoflower seeds grow from seed to harvest under 20 hours of daily light indoors. No change to the amount of daily light is needed for the autoflower plant to start flowering, it happens automatically (hence the name, auto seeds). Some growers regard autoflower seeds as a slightly simpler/faster way to grow cannabis. You can achieve very high quality cannabis levels from either feminised seeds or autoflowering seeds. Note that autoflowering seeds from Dutch Passion will only produce female auto plants, meaning that you never need to worry about male auto plants.

And Autofem Seeds Were Born

Autofem seeds are simply another name for autoflowering seeds. In the early days of autoflower seeds they were occasionally called autofems by some growers. The ‘fem’ part of the name refers to the fact that the seeds only produce female autos. Autoflower seeds/autofem seeds are one of the easiest ways to grow your own cannabis quickly. You don’t need to be an expert grower to get seriously impressive results from autofem/autoflower seeds.

Feminized vs Regular Seeds

Regular cannabis seeds produce roughly equal numbers of female and male plants. Some old-school traditional growers prefer regular photoperiod seeds if they are e.g. collecting male pollen for breeding projects. But most people strongly prefer to grow from feminised seeds which give rise to mainly female plants.

When using feminised seeds the grower can use a smaller grow room with fewer plants, compared to regular seeds. Dutch Passion are one of the few remaining seed companies to offer a full collection of regular seeds from the best classic varieties.

Some medical growers find that THC rich cannabis strains are the most helpful. Others find that CBD rich strains offer better physical effects with a slightly milder (less intense) high. Much depends on your own personal preferences. Dutch Passion offer a range of THC rich strains, CBD rich strains and strains with balanced levels of THC:CBD. It’s important to state that each medical user will have their own preferences for indica or sativa, THC or CBD. This means the medical grower will need to research the strains most likely to help them.

Top 10 Tips For Growing Feminised Seeds

Growing your own cannabis is really easy. With the best feminised seeds you will grow better quality cannabis than you can buy. Home grown cannabis is easy and enjoyable to grow and cheaper than buying it. Here are our top 10 tips for growers.

1. Choose your feminised cannabis seeds and your supplier carefully!

Even the very best growers can’t produce top quality buds from second rate genetics. You need to use the best quality feminised seeds, grown from the finest quality genetics. Dutch Passion were the original inventors of feminised seeds. Since inventing feminised seeds, the Dutch Passion team have constantly strived to further improve the results achievable from them.

Don’t cut corners when it comes to the choice of your cannabis seeds. The cost of the cannabis seeds is a very small part of the final overall harvest value. It pays you to research your options carefully. Does your seed supplier have a good track record in feminised seeds? Have they been able to gain any professional recognition with cannabis cups? Has your seed supplier stood the test of time and remained at the top of their profession for decades?

2. Try not to over-complicate your grow

Gain experience slowly, don’t be tempted to try complicated grow techniques (such as deep water culture hydroponics) until you have completed several successful grows. Often, people will start growing in large containers of soil. This minimises the need to quickly become an expert in nutrients, and allows an easy way to understand the basics. Cannabis isn’t difficult to grow, it’s called weed for good reasons! The new grower is encouraged to learn the fundamentals of cannabis growing before attempting to learn more technically demanding skills and techniques. Organic growing in soil is recommended and Biotabs is good nutrient line for beginners to start with.

3. Continual improvement of your grow room

Try to learn something from each grow, improve your skills and grow experience, learn what you can from the internet and books. Avoid temperature extremes, indoor plants don’t like temperatures above 30ºC, nor do they like being much below 20ºC. Indoor growers typically like to keep the temperature around a steady 24-25ºC with the lights on, and a couple of degrees cooler at lights out.

Many growers prepare their water the day before it’s required. This allows the temperature of the water to match that of the grow room. Never use ice cold water, it will shock the roots. Some growers feel that allowing the nutrient mix to stand for a day before use allows any Chlorine (often used during water treatment) to be released from the water.

Experienced cultivators insist on using pH meters to ensure their water and feed solutions are at the correct pH. Likewise, they will often use EC meters to monitor the electrical conductivity of their feed solutions. EC, or electrical conductivity, is a measure of nutrient concentration. Meters should always be calibrated and checked before use. Professional growers will always have spare meters available in case one fails.

4. Growing feminised seeds outdoors is easy too

Growing feminised seeds outdoors is even easier than growing indoors. In the northern hemisphere, feminised seeds are often harvested around October. Often the grower will germinate the feminised seeds indoors. (see the Dutch Passion guide on best ways to germinate cannabis seeds). This gives the seeds the best possible start, and protects the seedlings from the worst of the early season weather while they are at their most vulnerable. After a couple of weeks of indoor cultivation, the seedlings can then be planted outdoors when the weather is warm and the last frost has gone.

5. Experiment with different periods of vegetative growth

It’s common to use around 4-5 weeks of vegetative growth (before bloom) when growing feminised seeds indoors. But some growers get great results with longer veg periods of 6-10 weeks. The extra time spent in veg allows for a larger final plant size. This is great if you prefer to have smaller numbers of XL yielding plants and have the space to accommodate them.

For some growers who don’t mind large plant numbers, it’s possible to grow feminised seeds with just 1-2 weeks of vegetative growth (or even none at all!). The result will be a fast ‘Sea Of Green’ harvest of medium size plants which may often have the bulk of their buds on the main bloom.

For outdoor growing it is recommended to pre-grow (18 hours of light per day) the plants indoor for at least a few weeks. Between 3-4 weeks will usually do, use even longer VEG periods if you are looking for the biggest outdoor plants as possible. It will ensure a stronger and healthier plant that will cope better with tough outdoor growing conditions than a young, freshly sprouted, seedling.

6. Avoid the temptation to over feed your cannabis plants

One of the most common mistakes, especially from less experienced growers, is the temptation to over feed their plants. Over-feeding plants can permanently damage and ‘burn’ the roots of cannabis plants, especially young plants. It is crucial to start feeding nutrients at low concentrations and steadily increase. At the first sign of nutrient burn (perhaps you will note the ends of the leaves turning white/yellow and eventually brown and crispy) you should reduce nutrient concentration immediately and consider a water flush for several days in a row.

Overfeeding your plants will not increase size or potency, but it can permanently stunt the growth of your plants. Understand your nutrients well and never add more nutrients than necessary. Less experienced growers may benefit from a simpler nutrient regime, avoiding an over-complicated array of nutrients until they are more experienced.

7. Avoid the temptation to over water your cannabis plants

Along with using excessively high nutrient concentrations, another of the most common errors is the tendency to over water their cannabis plants. This is also a frequent error seen among new growers. Cannabis roots need oxygen to thrive and grow well, roots do not grow well in water logged soil. Using excessively ‘wet’ soil will limit root growth, this will restrict the final size and quality of the plant.

Experienced growers will often use a moisture sensor in their grow medium which measures moisture content and indicates when the roots are too dry. Products like the Blumat Moisture meter are recommended to prevent over watering. Note that numerous growers find new grow containers such as fabric grow containers or Air-pots are a great way to improve levels of root oxygenation.

Compared to traditional grow containers, felt grow sacks and air-pots allow good levels of root aeration and are recommended. Another tip is to mix some coco medium through your soil, this will improve the aeration levels too.

8. Find out when you prefer to harvest your buds

Feminised seeds offer the perfect amount of grower control over the final result. You can opt for long or short veg periods and have some control over the final plant size and yield. Connoisseur growers also know whether they prefer their buds harvested on time, or perhaps a little early/late. Some growers find that giving the buds an extra week or two in bloom can give a heavier, ‘stonier’ feel to the high.

Conversely, harvesting a little earlier may allow a faster harvest and perhaps a slightly more ‘lively’ or energetic quality to the high. Much depends on your personal preference. But the next time you harvest a plant grown from feminised seeds, consider harvesting a portion of the buds earlier than usual as well as harvesting some buds later than usual. After curing, try comparing the buds and see if you have a strong preference.

9. Consider upgrading to LED lighting

As your experience improves, consider LED lighting. LED is more expensive than HPS, but it is used extensively by serious growers. HPS lights were never designed for cannabis cultivation, they were simply a cheap option which worked. LED lights have a spectrum optimised for cannabis growing and they emit less heat than HPS. LED growers find they use less electricity and have less heat issues compared to HPS growers. But the main benefit of LED is the scope for quality/potency improvements. Most growers find they can push potency and flavour to new levels by upgrading to LED, and would therefore never switch back to HPS.

10. UV supplemental lighting

Some growers are starting to use supplemental UV lighting to boost the potency of their harvests. The idea is to mimic the effects of the UV content in the sun’s rays. Professional cannabis growers have found that adding UVB to their grow room can improve cannabinoid content. THC levels can increase by 10-25% relatively.

Historically, the cheapest way to add UVB to the grow room is to add a few ‘reptile tubes’. These are fluorescent tubes with a high UVB output designed for indoor lizard owners. Usually, cannabis growers add UVB for 2-3 hours per day for the last 2-3 weeks of bloom. But some UVB specialists claim that a small background presence of UVB can be used from the start of the grow.

Other types of UV lighting, like UV-A, are being explored as well. First reports showed UV-A could have significant effects on terpenes and the aroma of cannabis, as well as having a small effect on photosynthesis. UVC is used for sterilisation, to kill bacteria or get rid of pathogens, but is very damaging to all living things in a high dosage.
