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.
Start by filling a small pot with soil, no more than half a liter. Water it before even thinking about planting your seed. Once the soil is damp enough to weigh down the plant pot, use the tip of your finger to create a small 0.5-0.1cm hole in the middle of the soil, and deposit the seed in the hole with the root facing downwards. Then, cover the seed with a little soil so that it’s just under the surface. The last step in this process is to put your plant pot in the sun or under your lamps (wherever you’re planning on growing it). Within a couple of days you should see that first sprout, that will keep on growing right until the end. In some cases, it may even take a matter of hours.
Submerge your seeds in your B.A.C. X-Seed liquid for an hour. Give it a stir every now and then so that the seeds are thoroughly soaked.
Step 6: Temperature adjustments
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.
One of the downsides to using starter cubes is that they’re not very handy if you only want to germinate one or two seeds, because they’re usually sold in packs of 50 or more, and once they’ve been opened most cubes tend to dry out within a couple of weeks. Another downside to Rockwool specific cubes is that they’re bad for the environment, can be bad for your health when inhaled, and they’re not the best method for new growers.
After your seeds have been in the B.A.C. X-Seed liquid for an hour, by using a spoon you can carefully extract the seeds from the liquid and spread them evenly across the bottom of your plate or container. An even spread is important, so as the roots of each seed do not get tangled – about an inch apart is good.
We highly advise against using this method, as it’s incredibly easy to accidentally drown your seeds. This method involves soaking your seeds in a glass of lukewarm water – it can be any type of cup, although people usually use a normal glass. This method can be effective for much older seeds or for seeds that have abnormally thick shells.
Depending on the flowering time of the particular strain you’re growing, your plants could be harvest-ready either by mid-winter (if you germinated your seeds in fall) or mid-fall (if you germinated in summer).
In some strains, cold weather may also trigger hermaphroditism, meaning that the plant grows both pollen sacs and buds, leading to self-pollination and dramatically decreased yields in turn.
What Effect Do Cold Temperatures Have On Flowering 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.
If your plants have started to flower, you’ll need to be even more careful. If you give them more light indoors than they’ve been getting outside, they may revert back into their vegetative cycle. This process is known as revegetation, and causes extreme stress for the plant.
In this article, we’ll walk you through everything you need to know about growing cannabis during those chilly winter months.
Greenhouse growers are similarly affected by the reduction in daylight hours during winter, and unlike those growing on their windowsill at home, additional lighting may attract unwanted attention.
It is also highly recommended that winter growers purchase a device called a hygrometer. This device can test the relative humidity of your soil as well as your grow room. It is essential to regularly measure the relative humidity in order to stay on top of it and avoid huge spikes or drops in the concentration of water in the air.
Other things to consider when growing in winter
I am doing my first winter greenhouse crop. The lighting in the winter is not sufficient to bud out my plants so can I use flourescent lighting or must I use sodium lights?
If you think that growing cannabis in a European winter is impossible, then you’ve been misinformed. With the right conditions in an indoor growing operation, you can successfully yield good quality cannabis. We are here to teach you how to set up and optimize your grow room in the winter time.
A temperature gap of 2-4°C (3.6-7.2°F) is ideal for the first 2-3 weeks of flowering. A gap of no more than 10°C (18°F) should be maintained for the rest of the flowering period.
