how to germinate cannabis seeds in winter

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.

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.

We all know that cannabis grows best in areas with warm summers and plenty of sunshine. But, being such a versatile and hardy crop, you might be wondering whether it’s possible to grow cannabis in cold weather. Thankfully it is, but there are some key tips and tricks you’ll need to keep in mind.

Can You Grow Cannabis Outdoors In Winter?

Old school HID growers may be able to avoid turning on the heating during the dark cycle if they run their lights during the cold winter nights. Daytime temperatures are usually a little higher, so it might be possible.

In this article, we’ll walk you through everything you need to know about growing cannabis during those chilly winter months.

LED lighting systems are rapidly overtaking HID bulbs as the cultivation lamps of choice for Millennial weed growers, but the technology is still to be perfected. LED lights run cooler, because they emit almost 75% of their energy as light. This is fantastic most of the time and usually makes for easy environmental control in the grow tent.

Moisture from rainfall, snow, or frosts can build up and become trapped on a plant’s leaves or flowers, triggering mold issues that can be extremely hard to get rid of. That, in turn, can cause the flowers of your plants to rot well before they’re ready for harvest.

Let’s say that plants born from auto-flowering cannabis seeds and fast growing cannabis seeds are more resistant to low temperatures than seasonal plants. They come from Cannabis Ruderalis varieties crossed with Indica or Sativa. But don’t expect them to resist frost and extreme temperatures!

Alternatively, if they are in a region with an extremely favourable climate, they can grow in pots and then you only have to shelter them during the evening, at night, and when the weather conditions turn bad.

Please note that our in-depth studies are only for information. We do not advise you to grow weed seeds because, if you are in the UK, you will commit an administrative or criminal offence depending on the situation. If you currently live in a state where it is allowed to grow marijuana for personal use, then you can rest assured.

The perfect conditions for cannabis plants development

Although automatic cannabis strains flower not according to temperature and light conditions but according to their age (they are usually ready for harvest about 10 or 11 weeks after germination). If grown outdoors in the middle of winter they may still die or stop growing. At best, they may produce very few flowers with low THC and CBD content.

The answer to this question is no! Marijuana plants need special conditions to develop and flourish at their best.

Besides, it is not uncommon for rainfall, frost and other situations to occur during the winter months. They will be the perfect conditions for mould and fungi development, which are very harmful to cannabis plants.

Growing marijuana seeds on winter is undoubtedly possible, but not outdoors. For marijuana plants to develop outdoors in the best possible way, they need favourable climatic conditions.
