Best Strains to Grow in Winter

If you’re lucky enough to live somewhere that has a climate that allows for it, outdoor cannabis growing is one of the least expensive ways to grow cannabis. However, it’s also a lot more complicated in other ways; outdoors you have to deal with nature’s wrath, changing temperatures, insect infestations and rain. For those that live in more extreme climates and are thinking of starting a late grow, you’ll want to figure out the best strains to grow in winter before getting started.

That’s where we come in – while growing cannabis is more or less the same for all strains, some deal with certain conditions much better than others, and some particular strains are well-equipped to deal with colder temperatures, which gives them a fighting chance during the colder winter months.

Some of the Best Strains to Grow in Winter

Keep in mind that the structure of the plant itself is going to influence how well it does in colder climates, which tend to be more humid too. You’ll want to go for a strain that grows airy, open buds that can easily release extra humidity, which when combined with low temperatures can cause plants to rot. Growing during the winter can be complicated enough without attempting to grow the wrong type of strain.

Northern Lights

NL is a pure indica strain that is known to pretty much every grower out there, and has been used in countless hybrids over the years since the 70s. The best thing about Northern Lights is that it’s the perfect strain for beginners, as it can deal with quite a lot of stress and mistakes before it reaches breaking point. Plus, this strain is known to do well in colder climates, and although there are many ph3enotypes on the market the general rule of thumb is that it should be ready by late October at the most, which gives it enough time to grow successfully without the harsher winter temperatures. We highly recommend trying GB Seeds’ Northern 100% Feminized.

O.G. Kush

O.G. Kush is a hybrid strain known for its ability to easily adapt to stressful situations and its fast growth. Plus, the autoflowering version takes just a total of 70 days, allowing you to grow it in colder climates with the correct care and still obtain decent results. Although it does well with cold climates, it’s slightly more susceptible to insect infestations. One of the best ways to keep insects at bay is by using Multiprotection Boom to keep your plants as strong as possible. We highly recommend GB Seeds’ Auto OG Kush 100% Feminized.

Durban Poison

Durban Poison is almost entirely sativa and it definitely shows it. This African landrace strain can easily deal with extreme temperature fluctuations, as it was originally grown in areas where temperatures can go from 40°C to 10°C in the blink of an eye. However, it can grow quite tall outdoors so you’ll need to make sure that you have enough space to do so. This strain can produce amazing yields, over half a kilo per plant when grown outdoors, and it does well with stressful issues such as extreme weather. You should be able to harvest it towards the end of September when planted on time, which is quite fast for a sativa strain. Planted later, it can grow smaller and still produce decent yields.

Wild Rose

Wild Rose is a hybrid with some complex characteristics, originating from a cross between Rossetta and The Hog, making for the ideal strain for cold and mountainy areas. It’s the perfect strain for growers looking for a special taste, offering flavors such as strawberry and sweets. It has an extremely relaxing effect, making it the perfect strain used to forget your issues after a long hard day. It doesn’t have a very long flowering period, and it should be ready for harvest around mid-October in the North, and in the Southern Hemisphere it should be ready by mid-April.

Pakistan Chitral Kush

Pakistan Chitral Kush is one of the few indicas that is perfectly capable of dealing with low temperatures, so if you’re looking for a relaxing, stoned strain then this might be your best option. This landrace strain comes from Chitral in Pakistan, where there are continuous temperature changes, meaning that this strain has gained low temperature resistance generation after generation. On top of that, in areas with low temperatures the plant will turn a nice purple color. This strain also has a high resin production rate, and you can use its amazingly sticky leaves to make extractions that have an extremely relaxing effect. Its fast flowering genes will have it ready by the end of September in the Northern Hemisphere, and towards the end of March in the Southern Hemisphere.

Snow Bud

Snow Bud is one of the most adequate strains for cold climates due to its Swedish strain heritage which makes it extremely capable of dealing with the lowest, most extreme temperatures. As long as this strain gets plenty of light it should grow strong and healthy; after generations of growing on the top of mountains, this strain is more than capable of dealing with the worst sort of climate situations. It has a complex and balanced effect; it begins by relaxing your body without making you feel “stoned” and then combines this with a happy, creative sensation. In the northern hemisphere this strain should be ready by mid-October, and in the south, mid-May.

Best Strains to Grow in Winter – Extra Precautions

Just because these strains are capable of dealing with low temperatures doesn’t mean that they’re immune to fungi, so you should still take preventive measures to avoid any nasty surprises. If you use a decent Propolis fungicide such as Propo Boom you should be safe and so should your harvest. You should also protect your crop from wind, rain or possible scavengers to get the most out of it.

There are a lot more strains that do well in cold climates, but here we’ve given you some distinct strains so that you can choose between tastes and effects.

Growing Cannabis in Winter

As the cold season approaches and we start to prep for the cold in some areas around South Africa. ZaOg thought it would be a good time for us to reflect over what a budding grower can do to carry on cropping during the months of the winter blues. A short write-up on growing Cannabis in Winter.

Wont the cold kill my plants

As the temperatures are set to drop around Cape Town I was always under the impression that I would be unable to grow again till September. While the conditions aren’t nearly as prime there is still a way to crop a few sneaky buds. While researching for the Autoflowers Explained blog post what I found most interesting was the information regarding the Ruderalis genetic being found in cold climates such as Russia. Extra cold tolerance and not being dependent on photo-period are two factors contributing to the autoflower being able to succeed near year round.

Short days and long nights

This is a factor to consider when growing outdoors. Regular seeds would go straight into flower while the Autoflower would only flower when mature. Keep your plants from getting too wet, bring them in if you can on super cold nights and remember the high humidity can cause mold. If you aerate enough this shouldn’t be a problem and you can look forward to an excellent growing season during winter.

Enter Autoflowers

Bred from Ruderalis a genetic native to areas with cold climates the Autoflower is far more cold resistant than its other counterparts. Also because it doesn’t rely on photo period it will reach maturity before it sets into flower.

What can I do to improve my outdoor grow in winter?

Greenhouses are an excellent way to maintain a warmer environment during the cold winter months. MSA has just sourced some excellent grow houses suited to Autoflowers and regulars and will be adding it onto the site soon. Indoor growing is also always an option, but we will go more into that in further posts. Check out our grow section so long for some ideas.

Seeds to sow in the winter

If you’ve spent the last few weeks diligently weeding, it’s time for a wonderful treat. Just as weed seeds sprout abundantly in cool, moist conditions, so will the seeds of hardy annuals, including many lovely native wildflowers.

As you tidy up beds and borders and refresh soil in window boxes and containers, scatter seeds of these cheerful annuals in the freshly prepped areas. There are dozens of hardy annuals to try, and any or all will be more attractive and rewarding than the weeds they replace.

You’ll also find that native annual wildflowers attract many different pollinators, including native bees as well as European honeybees. If you let native wildflowers go to seed (as wise gardeners do), you’ll also notice seed-eating birds feasting when the seedpods ripen in early summer.

To teach yourself to recognize seedlings of wanted plants from weeds, leave a label or marker to remind yourself what you sowed where (strips cut from plastic containers make excellent short-term markers). Next, sprinkle a few seeds in a small nursery pot and leave it near larger patches direct-sown in the ground to make sure they match. Sow various seeds in small pots in order to have extra plants to fill in bare spots and skimpy containers come spring. As the seeds sprout, take a picture of each kind every few days to familiarize yourself with them as the seedlings grow. Often the first pair of leaves (called seed leaves) don’t look like the true leaves, which appear as the seedlings grow larger. Once you can recognize both the seed leaves and the true leaves, you won’t have to worry about pulling out the wrong plants and accidentally nurturing a bunch of tansy or shot-weed (!).

It feels very hopeful to grow flowers from seed in winter, when the world can seem dim and gray. Just choosing the seed packets, with their colorful pictures, can lift the spirits on a cold, cloudy day. Alyssum and Calendulas, Larkspur and Nigella, Pansies and Poppies will all sprout quickly and be blooming by spring, as will fragrant Sweet Annie and perfumed Sweetpeas. Native wildflowers are also quick workers, from the familiar California Poppies, Clarkia, Columbines, and Lupines to less common Baby Blue Eyes (Nemophila), or Poached Egg Flower and Meadowfoam (both Limnanthes species). These wild things are generous self-sowers, so let them set and ripen seed before pulling them up. You’ll be rewarded for years to come with carpets of early bloomers that fade and vanish by the time summer flowers take the stage.

If you mulched your beds in autumn with compost, bedding straw or autumn leaves, you won’t have as much weeding to do before you get to the fun part. Where the mulching materials linger, looking much as they did last fall, don’t worry, they’ll soon molder into nutrients that feed both soil and plants. If you want to sow seeds now, just push the leaves or straw aside and scatter seeds over the bared soil. When it’s time to plant spring starts, do the same thing as you dig your planting holes. Once your seeds sprout and have several sets of leaves, and again when you plant spring starts, you can snug a little of the compost or well-rotted material around each plant. For now, just move larger clumps of leaves or flakes of straw to the back (or middle) of the bed until the new plants are off to a good start. Onward!
