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.

MSA has stocked up on all of it’s Autoflower seeds in anticipation for the winter season.

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.


Dont let the cold and wet ruin your vibe. Grow indoors or make a plan outside. We are blessed with an excellent climate in South Africa and need to make the most of our newly aquired freedom to grow our favourite herb Mary Jane

    my plants started flowering immediately ( two leaves)and now have beautiful buds even though the weather has been very cold at times. not many sigmas bud tons of trichomes. But now that the days are getting longer I am worried all the activity will now go into leaf growth and then I will be landed until May for harvesting. So the trichomes are clear and thats where I am. Shall I harvest?

    Just harvested my winter grow – enormous buds! Really great – started showing stigmas immediately ie four leaves and coped really well with very cold conditions here in the Karoo. Didn’t attract any attention because of being short. Planted the late May after summer harvest – so completed grow infer months.
