The dome of the plastic container will create your seeds’ own mini tropical climate. If you then place all the components in a temperature-controlled cupboard, you will have created a self-perpetuating supply of moisture—no need to touch the seeds again until they are ready to be transferred to your final growing medium as a young seedling. Using the stone wool block method, your seeds should germinate in one to two days.
After 3–5 days, the seeds will start to open, and you should see tiny white tips appear. Once these roots reach 2–3mm in length, use extreme care to transfer them from the water to pre-prepared soil pots.
Start by filling pots with a premium-quality soil that has been soaked in water. Many growers also choose to lace the water with a root stimulator. Make a hole roughly 10–15mm deep. This will be your seed’s new home. Remove the seeds from their packet and place them into the pre-dug holes. Loosely cover the seeds, but be careful not to compress the soil above the seed too much. The root will struggle to penetrate solid soil, slowing plant growth. Lightly spray the top of where you placed the seed so that your growing medium stays moist.
PLANTING DIRECTLY INTO SOIL
Before we jump straight into the germination methods, there are a couple of germination golden rules. For the best results, we recommend staying within these guidelines, no matter how you choose to germinate. That being said, of all the factors to consider, temperature is one of the most critical. Seeds will always seek out even the smallest amount of moisture, but they use temperature as a sign that they need to do so.
Probably one of the most common methods of germination. The kitchen towel method comes in several iterations. Some growers use cotton wool pads or absorbent pieces of paper. For this guide, we will be using kitchen towel as it is readily available and holds moisture relatively well.
The soil pots will need small holes (roughly 10–15mm deep) for the newly germinated seeds to be placed into. Once the seeds are secure, you will want to place a fluorescent light 13–15cm (5–6 inches) away to encourage growth. Finally, don’t risk overwatering your seeds at this early stage. Use a plant mister to make sure they stay damp but not soaking wet.
Your growing pots will need to be placed in a damp climate that is within the temperature range listed under our golden rules. After 4–10 days, you should see a young seedling sprout, while the roots will have begun to develop underneath the soil. The entire plant and its soil can now be transferred to a larger pot, where normal growing routines should start.
This method is the method we recommend all readers and customers use, as it’s the one that has proven to give us the highest germination rate. We’re going to give an in-depth step by step guide on how to use this method. Keep in mind that you can skip the rooting hormone part if you prefer all natural results, although X-Seed does provide impressive results to start with.
Once you’ve finished covering your seeds with paper towel, cover them with another plate or put the lid on your container; if doing this in a container, the paper shouldn’t dry out as fast. A mistake made by many growers is that they add too much water to their paper towels if they’ve dried up, but by using a spray bottle you can moisten it some more without overdoing it. If your container is transparent, all you have to do is line the inside so that absolutely no light can get in.
Material Needed to Successfully Germinate seeds
There are a few myths surrounding germinating in water overnight – some people say that if your seeds sink, they won’t germinate, however the truth is that most seeds start off by floating and then as they soak, they sink to the bottom of the glass. This has nothing to do with germination indication.
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.
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.
Every cannabis grow is dictated by genetics. In turn, if you’re planning a winter or cold weather grow, your best bet at achieving a respectable harvest is investing in the right genetics from the start.
How Cold Weather Affects Cannabis Plants
This leads to another question: How cold can cannabis plants get before problems arise? Well, to answer that question, we first have to consider the perfect temperature for cannabis plants.
Note that this technique only works in regions with a mild winter or a warm spring. Don’t try this technique if you’re living in an area with harsh, cold winters and unstable spring temperatures. In these areas, you’ll need to build a greenhouse to protect your plants from the elements.
Ideally, you’ll want to look for strains with genetics linked to cooler areas of the globe. Indica-dominant strains and landrace varieties from mountainous areas of Asia, for example, tend to be much better suited to cooler temperatures than sativas.
