will cannabis seed germinate in cold

If you are fed up of having to wait for warmer seasons to grow marijuana, we invite you to continue reading this post, as it will be very useful to improve your winter harvest.

-If we use indoor lighting: Continuing with the previous point, and if we want to enlarge the photoperiod of the plant with the purpose of promoting its growth, we will have to use indoor lighting, as for example, LEC. In PEV Grow you can find a wide range of lighting equipment to help you getting the best results.

How cold affects marijuana

-Be careful with the humidity! Although the truth is that during the winter, plagues are less common, humidity can always cause pest problems. We must bear that in mind. We must always use preventive fungicides, especially during the rainy season.

For a long time and specifically in countries where it is not particularly cold all year round, as is the case in most European countries, a large number of marijuana growers devote to this task in the less hostile months of the year, i. e. those that range from April-May (germination and transplantation of seedlings and cuttings) to September-October (harvest), approximately, which is the time of outdoor harvest. The rest of the year, they devote to enjoying the production and prepare the next harvests.

-Smaller plants: Considering the previous point, it is logical that the plant we grow in winter does not reach a large size. In fact, it is estimated that they do not usually exceed 100 centimetres in height, but they can give us between 20 and 60 grams per plant. Although it’s not a good idea to do this with autoflowering plants, as these genetics will not have the photoperiod or the proper light intensity to provide an acceptable amount of vegetal mass.

Place one sheet of damp kitchen towel on a flat surface. Space your seeds a few centimetres apart before placing the second piece of kitchen towel over the top. You need to ensure both pieces are damp, not wet. Once again, when the white root tips reach 2–3mm, move the seeds (carefully) to soil pots. Use the same guidance found above for planting techniques.

To avoid disappointment, seeds that have a darker colouration stand a better chance of germinating, while pale green or white seeds are likely to fail. Even if dark seeds look slightly damaged, they should be planted anyway. There is a good chance they will still germinate, even if the outer shell is somewhat crushed.

You will need to invest in a few pieces of unique equipment, but by using stone wool blocks, you can create a perfect utopia for germinating cannabis seeds. Soak the stone wool blocks in the same way you would a soil medium. The wool will retain the moisture and prevent the need to water during the early stages of germination. After the wool blocks are soaked, stick them in a plastic tray that also has a lid. Large cake tubs are ideal.

GLASS OF WATER APPROACH

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.

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.

Small, fragile, and in desperate need of a helping hand, there are several ways you can germinate your cannabis seeds. All methods have varying degrees of success, with both advantages and disadvantages. It is important to note that even with advanced growing expertise and top-of-the-line equipment, you may still end up with a few failed seeds. This is a natural part of dealing with a living organism. At Royal Queen seeds, we only sell feminized cannabis seeds, so there is no need to worry about removing male plants.

Flowering with HPS lighting and vegging with MH bulbs usually requires serious air cooling. The old school grower can turn cold weather to his/her advantage and save some cash on the air conditioning bill at the same time. Some even add extra lights to boost yields when the weather gets cooler.

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.

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).

Force Flowering Outdoors

Once soil temperatures drop below 12°C, a cannabis plant’s metabolism starts to slow down considerably. As it does, the plant will struggle to take up water, nutrients, and oxygen from its soil, and many of the enzymatic processes needed to fuel its growth will come to a standstill. Over time, the plant will likely suffer from stunted growth or may even start to wilt.

No. Unless you live in an area with very mild winters and low rainfall, we don’t recommend growing cannabis outdoors during winter, as you’ll usually end up with sickly plants and/or poor harvests.

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.

Cannabis is a plant that loves being warm, sure, but that doesn’t mean you can’t grow it in other climates. With a bit of preparation, enough knowledge, and just a pinch of technical ability, you might just be able to grow healthy cannabis plants even in cold conditions.
