What is Boveda? – Marijuana SA


The Boveda is a game changer for humidity control

The Boveda is a small sachet that acts as a reactive humidity control system. Inside the sachet is a mix of salt and water contained by a reverse osmosis membrane. The sachet works to control the humidity based on the scientifically proven fact that when certain salts are mixed with water they naturally regulate the humidity around them.

Hows this related to marijuana?

Humidity is an extremely important factor you need to think about when storing your stash. Too high a humidity level you get mold, too little and your bud will get dry. So instead of having to ‘burp’ your jar, to ensure fresh air and the right humidity, you just have to pop a Boveda in there. The sachet will keep it at the perfect humidity, meaning you wont need to burp the jar and your stash will keep for a much longer time. The sachet’s can also be used for curing, once again keeping the buds at he perfect humidity to develop the flavour and smell.

How do you use it?

Boveda’s are really easy to use. You just throw the appropriately sized Bodeva in the jar with you bud, and let them work there magic. That’s it! So then to decide which humidity sachet to use. They offer the 58% and the 62% humidity sachets, keeping the jar they are placed in at their respective humidity levels. A rule of thumb is the 58% humidity should be used during winter or on wetter and denser buds, while the 62% sachet should be used during the summer or on lighter, dryer and less dense bud.

For a guide for the minimum boveda needed for the amount of bud, they are nice enough to offer a useful chart:

Boveda 4 gram: 7-14 grams of medicine.
Boveda 8 gram: 14-28 grams of medicine.
Boveda 60 gram: 112-450 grams of medicine.
Boveda 320 gram: up to 5 pounds of medicine. (2267,96 grams, phew!)

However, the more Boveda’s you use in the jar the more effective they will be!

Are you convinced?

We sure are convinced with this amazing product and its applications with storing and curing bud, so if you are interested be sure to check out our store or the number of other vendors that sell in South Africa.

Using a PH meter for Cannabis

pH is the cornerstone of healthy plants

Your pH level is really important for growing cannabis. If you do not have the right balance you can have issues like discolouring and a lack of growth. So one of the most important things a budding grower must do is test their pH. In our MSA video we demonstrate how to use our pH meter.

Cannabis plants like a slightly acidic environment. They grow the best when the pH level is at 6.0 – 7.0. Why is this important? Your plant needs nutrients to be healthy and grow. Cannabis plants only take in nutrients when the pH is between 6.0 and 7.0. Even if the nutrients are there, if the pH is wrong, the plant will lock them out.

So to keep a good pH level you need to be consistently testing the water and nutrient levels. That is where our pH tester comes in. Its unbelievably simple and accurate. All you have to do is insert the meter into the water or nutrients and it will give you a reading. You can see in the video how simple it was to use.

So if your pH is wrong what do you do? Well it is really important to fix this as soon as possible but luckily its super simple. You will need to buy some pH ‘up’ and pH ‘down’ products. So if your pH is high you add ‘down’ and if its low you add ‘up’. Tap water is usually in need of pH ‘down’ as its normally quite alkaline.

So do not wait until you have problems with your pH. Buy a pH tester to ensure your plants are happy and healthy.

Growing Cannabis in Winter

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 shouldnt be a probelm 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

Personally, I wouldn’t bother growing without getting a good seed first.

In South Africa there are numerous seeds suppliers that have popped up lately. However, you should do your research before make a purchase.

If you are looking for a supplier have a look at our stock under Marijuana Seeds. However we know that there are thousands of different strains and breeders out there so we cant help you with everything you need. Not to mention the stock fluctuations in the business.

From being in the industry there are a couple of suppliers and breeders that we have identified.

Autoflower Cannabis Explained

Autoflower Cannabis

As you have already noticed MSA hosts a good variety of Autoflower seeds. With our next shipment arriving early next week all of your favourite autos will be back in stock soon. We thought this was a good opportunity to take some time and talk about what exactly Autoflower Cannabis seeds are and where they come from.

Sativa, Indica and Ruderalis

Cannabis can be traced all around the world resulting in genetic differences. Everyone knows of a Sativa and and Indica however there is a third less common strain out there known as C. Ruderalis and she is the one that makes all our autos possible. Ruderalis originates from Asia, Eastern Europe and specifically Russia. Due to the more harsh conditions and varying light periods the Ruderalis has evolved to rely on maturity rather than light cycle. This allows for the Cannabis to flower basically under any conditions.

By breeding stronger Indica or Sativa with Ruderalis one gets a plant that goes from seed to flower in around 10 weeks while still producing a powerful bud. Its short life and smaller size makes it perfect for beginner growers who are still testing the waters and are not quite sure what setup they need yet. As well as more experienced growers who maybe have some space in their grow room they need filled. Because the light cycle doesn’t matter you can flower out your autos in your veg room and have something to smoke while you wait.

Characteristics of Ruderalis

Cannabis Ruderalis is a shorter plant compared to is Cannabis Sativa and Indica counterparts. Typically growing to around 50 – 60cm it has a rugged growth pattern and shape. The buds are spread out and are typically quite dense and supported by thick stems.

What really makes the Ruderalis so valuable is the flowering cycle. Instead of relying on photoperiod it relies on maturity. This allowed for the modern day Ruderalis hybrids that generally start flowering 21 – 30 days after the seed has been planted.

MSA Most Popular Autoflower

These seeds emerge from the successful crossbred between one Tangie Dream selected clone and one new Skunk generation clone, to end up crossing them with a Rudelaris genotype, in order to obtain its autoflowering gene expression.

Black Mamba Autoflowering from MSA is a mid-sized plant although this does not prevent it from having a high productivity, its buds have an earthy aroma and a characteristic Skunk-like flavor. Aromatic nuances of very little sweet skunky plant.
