How to grow weed in the cold

Seedlings and young cannabis plants can be particularly sensitive to colder temperatures. Instead of planting your seeds outside, start your cannabis indoors and wait until they are strong enough for transplanting. Put them outside in late spring when there is no more risk of frost.

Most of us are not so lucky as to live in a warm climate like Southern Europe or California. Growers in those locations can cultivate their ganja all year round without much trouble, but the short summers and long winters in our climate (Northern Europe) aren’t exactly ideal if we want to grow cannabis. Then again, growing cannabis in cold weather is possible if you know how to go about it. Even better, the chillier temperatures in our climate can actually have some advantages for growing weed.

Tip: If frost is expected, water your plants in the evening. This protects the roots from freezing.

Modern LEDs are now almost, if not equally as powerful as HID lamps, yet they use only a fraction of the power of HID lights. This can add up to significant savings on the grower’s energy bill over time.

To ensure your plants can survive any threat of frost, make sure to place them in a spot that gets direct sunlight in the morning. The reason for this is that it is better when plants can slowly defrost after a night of chill. This way, your plants may even be able to survive nights that drop below their healthy threshold for development. Growing spots near a lake or river can also be very good. They are naturally a few degrees warmer, so there is less risk for frost at night.

If you’re growing cannabis indoors, as many do, the cold temperatures in fall and winter can actually be an advantage. This is true for growers who still use HID grow lights with MH or HPS bulbs. Although LED grow lights are becoming increasingly popular, the “old-fashioned” HID lights are still widely used among many. They are also the most affordable type of grow light, and cannabis growers have used these lights to successfully grow cannabis for a long time.

HOW TO GROW MARIJUANA IN COLD WEATHER

Those places around the world where cannabis grows out in the wild have plenty of sunshine, fertile soil, and an optimal outdoor temperature of 20–28°C. In Northern Europe, including the UK, the Netherlands, Germany, and many other parts of Europe, we can feel lucky if we get such optimal outdoor growing conditions for a few short weeks in summer. Then again, this doesn’t have to be a problem if we grow indoors.

Contrary to what some might say, it is possible to grow weed with good results outdoors in cooler climates. You can in fact grow outdoor marijuana all year round if you plan your grow well. For example, it can help to know the weather particular to your area so you can time your harvest to beat mould and frost. Here are our tips on how you can grow marijuana in cold weather.

It’s true that the ideal season to crop the vast majority of cannabis seeds is when it is not particularly cold and the hours of sunshine are abundant (long photoperiod), helping its growth and proper development. However, cold temperatures should not prevent you from growing cannabis all year round. In this post we’ll give you some techniques to achieve it.

In addition, these seeds need less time to develop and, although they will not give large plants, the results will be good if we take into account the advice given in the previous section.

Hot grow lights help keep plants warm. If it’s getting cold at night, change your timer so grow lights turn on in the evening during the coldest hours.

Let me elaborate a little more on changing the light schedule. It’s common to grow in a garage or attic that is an okay temperature during the day but too cold at night when the grow lights go off. In this case, change your plant’s light schedule so the grow lights turn on at night (during the coldest hours) to help equalize day and night temperature.

Be prepared for a power outage

One challenge for growers in wintry climates is the impending chance of their electricity going out during the winter months. Indoor growers rely on electricity to keep plants alive, especially in the winter, so it’s a good idea to prepare ahead of time.
