Marijuana Growing Tips: Protecting Marijuana from Cold Weather

Some parts of the world, like California and British Columbia, are famous for growing incredible cannabis plants, but many of us aren’t lucky enough to live in a climate that’s naturally conducive to the cannabis plant. For those who grow while battling the elements of winter, we’ve got some tips and tricks that will have you producing excellent crops all year long.

The first thing you’re going to need to think about is how plants grow and flower according to the amount of light they receive, and when the days begin to get shorter your plants should begin flowering. This works the other way around too; if your plants are flowering when the days start getting longer they’ll begin revegetating and they’ll go back into the growth period. When purchasing seeds, make sure you have a good understanding of what you’re buying, especially if you plan on doing your growing during the winter months. Most seed banks will sell seeds designed for cold weather; they’re the toughest and take the shortest amount of time to flower.

It’s important to create the perfect growing environment for your plants. Maintaining a grow room at 70–80 degrees Fahrenheit is ideal as cannabis plants will suffer if they’re in an environment below 60 degrees. One of the most important things to keep in mind is that the temperature of the roots can’t go under 16º or they’ll stop absorbing nutrients, causing your plant to stop growing as much. Planting in flowerpots is not the same as planting straight into the ground; flowerpots are much more likely to get cold, whereas underneath the ground tends to be much warmer than above. Plants can but up with cold on their leaves as long as there’s no frost, but if the roots get cold you can kiss your harvest good bye.

The most common winter grows are done in greenhouses. You can grow in flowerpots or straight into the ground because they won’t be as cold in the greenhouse as they would be outdoors. You’ll need to let them grow for around a month or month and a half indoors and then transplant your plants into the greenhouse where they can get a bit more heat at night time. You can also germinate them in the greenhouse from the get go around September, but your plants will definitely be smaller.

By using high-pressure sodium bulbs rather than LEDs and CFLs, you should be able to keep a small to medium grow at ideal heat so you can produce cannabis all year long, despite the cold. When plants are under lights they behave quite differently, because although it may be winter your plants are getting the summer sun every day. They have the perfect climate and you can adjust the parameters as needed. It’s extremely hard to grow indoors during the summer without air conditioning, but it’s perfect for growing in the winter.

Marijuana needs both the proper temperature and humidity to grow. For cannabis, a humidity level of 60 percent is ideal. This high percentage can be hard to maintain during the winter months when the humidity tends to drop, usually because of indoor heaters drying the air. If more moisture needs to be added, consider buying any standard humidifier to do the job automatically or take a manual approach and dampen the leaves with a spray bottle regularly.

If you’re planning on growing this winter you just need to follow these techniques and pay close attention to your plants, harvesting by the end of the year. Remember, tricking your plants with the light periods is something you can do all year round if you want to, not just during the winter. Growing cannabis is a passion that shouldn’t be limited to the summer season. It is, of course, a challenge to battle Mother Nature but it’s not impossible to grow cannabis during the winter months. Visit your local hydroponic store to discuss the best growing options in your area and ensure you’ve done ample research before investing money in your grow. Inexperience is usually a bigger killer than the winter’s chill.
