Sexing marijuana plants can be a time-consuming process, and if you don’t catch males, there is a risk that even one males can pollinate your entire crop, causing all of your female weed plants to produce seeds.
Seeds for these varieties are now widely available online and through dispensaries. It should be noted, however, that any plant grown from these seeds is not guaranteed to produce high levels of CBD, as it takes many years to create a seed line that produces consistent results. A grower looking to produce cannabis with a certain THC to CBD ratio will need to grow from a tested and proven clone or seed.
Pros and cons of using cannabis clones
Within a week or so you should see a seedling begin to grow from the soil.
But sometimes you get lucky and find a mature seed in some really nice herb. Strains like the legendary Chemdog wouldn’t be possible without adventurous smokers planting and proliferating the seeds they found in a bag of kind bud.
In some cases, even if a seed isn’t completely mature, there’s still a chance it could be viable. But often these are extremely weak, take long to develop, and express other unfavorable characteristics. Growers usually discard weak plants to free up space.
We’re going to go through the X-Seed method – if you want to skip this, you can simply skip the steps involving X-Seed and place your seeds straight into your paper towel as stated in step 4. Before you start, make sure you have everything you need at hand, so that you don’t have to waste any time looking for stuff.
There are many different germination methods that growers tend to use, all of which involve water and heat, although they’re not all as effective as others. Some people prefer germinating by planting straight in the ground, using starter cubes or by letting them soak overnight, although our preferred and recommended method is the paper towel method using either plates or an opaque kitchen container. We’re going to give you a brief rundown of the other methods, alongside their pros and cons.
Once you’ve isolated your seeds from light, you should leave it somewhere with a nice, neutral temperature. During winter it’s often harder to find a good spot, so you should try and find a heat source that isn’t excessive. You can use a computer modem, or even a softly powered electric blanket. Items like play-stations can get too hot and could end up cooking your seeds, so take care where you put them.
Step 1: Soak the seeds
Some cubes are made out of peat and soil, and you can move them straight into your flowerpot once they’ve popped. However, hydroponic growers can use rockwool cubes which can hold quite a lot of moisture.
This can be the hardest thing to work with, because temperatures that are either too cold or too hot will mess with your seeds and they won’t germinate. Springtime temperatures are generally what you should be aiming for – seeds can still germinate in colder temperatures, although they can take longer.
Germinating cannabis seeds isn’t a complicated process, although it does require a few specific parameters in order to happen successfully. If you’re reading up on how to germinate weed seeds, you’re in the right place; it’s a relatively easy process, you just need to have some patience on hand. The first thing to keep in mind is that your seeds are going to need water, heat and air in order to germinate.
Now that your seeds have officially germinated, you need to move them to the medium in which they will remain for the rest of the growing process. Germinated seeds are generally moved to soil, but they can also be planted in rockwool for hydro growing, or in a coco jiffy if you want to cultivate in coco coir. In this article we’ll be dealing with the most common method: planting seeds in soil.
Soaking cannabis seeds during germination causes them to stagnate.
As shown by the video, perfect germination occurred when the cannabis seeds were germinated between lightly sprayed (i.e. moist) cotton pads. All 15 seeds germinated perfectly. However, of the 15 seeds that were placed between soaked (saturated) cotton pads, only 3 seeds were able to survive. The others showed brown coloration on the embryonic root, this is a sign that the root had started to rot in the waterlogged conditions.
Note that the moist cotton pads were placed on a dinner plate and the plate was sealed with transparent kitchen film. This ensured that the moist cotton pads didn’t dry out. If this happened, the germinated seeds would eventually die. The experiment took 4 days, though many home growers would perhaps inspect after the germination after a couple of days and re-plant the germinated seedlings into a grow container.
The disadvantages and problems caused by trying to germinate cannabis seeds in soaked conditions
For the 15 cannabis seeds that successfully germinated in moist conditions, we ensured that the cotton pads were lightly sprayed (3 times for the lower cotton pad, 3 times for the upper pad).
In the Dutch Passion ‘moist vs soaked’ cannabis seed germination experiment, some simple cotton pads were used. This is usually a reliable way to germinate seeds, whether you are using feminised seeds, regular seeds or autoflower seeds. Note that for the successfully germinated seeds in moist conditions, a minimum amount of water was used and delivered the best results. Just 3 light water mist sprays were given to each cotton pad.
What’s the best way to germinate cannabis seeds? Let’s pursue our germination test series with another critical matter: should the seeds be placed in moist conditions, or is it better to completely soak the seeds to ensure the highest germination rates and the fastest germination speed? The answer may surprise you!
Experienced cannabis growers know the dangers presented by soaked/saturated seed germination conditions. That’s why many of them avoid using e.g. toilet tissue, which can hold a lot of water and not drain well. In the Dutch Passion moist vs soaked seed germination video, only 3 of the seeds just about survived the waterlogged conditions. All the rest were ruined by the soaked/saturated germination conditions.
