How to Grow Bubba Kush Marijuana

If you’re keen to grow your favorite marijuana strain, we advise you to check out our large number of grow guides, which provide you with important steps and tips to help you achieve a rich, bountiful harvest. Today’s growing guide is for Bubba Kush, a strong indica-dominant (90%) hybrid with a THC content of up to 25.25%.

Bubba Kush is no doubt one of the world’s most popular strains of marijuana. This descendant of the legendary OG Kush strain has a long and illustrious history. Whenever people use the term ‘Kush’ to describe a strain, we are transported to the remote Hindu Kush mountain range, which extends from Afghanistan to Pakistan. According to the breeder who claims responsibility for introducing Kush to the U.S., no one had a clue what they were planting!

Bubba Kush: What Is It?

As for the Bubba Kush strain itself, we can trace its origins back to Denver in the early 1990s. According to legend, a grower called Bubba and his friend Learch germinated some cannabis seeds that they had ‘gotten from a friend’ – even they didn’t know the name or origins of the seeds. They called the strain ‘Kush,’ apparently without knowing anything of the existence of the Hindu Kush mountains.

Next, Bubba and a few other growers crossed Skunk varieties with their version of Kush. They ultimately created some new strains called KX, KY and KZ, with KY being the pick of the litter. Bubba was so happy with the KY strain that he named it after himself.

In 1996, he moved to LA with a college buddy and set aside the KY strain to create Kush and Bubba plants. Bubba and his friends had a major problem while in LA, though: the Kush grew too tall!

What they failed to realize was that their hermaphrodite Kush strain had pollinated the newly-minted ‘Bubba’ strain! They named the ensuing strain Bubba Kush. (It is also claimed that a member of Cypress Hill got hold of the seeds and was responsible for making it famous).

Regardless of how Bubba Kush came into being, it is a strain known for providing an extremely relaxing effect.

Initially, your muscles will lose tension before a period of heavy euphoria envelops you. As time passes, Bubba Kush also provides you with a hazy head high. Due to the nature of these effects, Bubba Kush is best suited for evening use or before you go to sleep.

If you are interested in growing Bubba Kush, check out these eight tips to achieve the best, most potent yields.

1 – Should Bubba Kush Be Grown Indoors or Outdoors?

If you want to enjoy this potent strain with its chocolate and coffee flavors, is it best to grow it inside or outside? In truth, you can grow Bubba Kush either indoors or outdoors with excellent results. This hardy variety is not too difficult to cultivate, barring the usual differences between the two growing methods.

If you elect to grow outdoors, you can do so in a dry, springtime location. However, this plant is tough enough to survive slightly lower temperatures. It is usually ready to be harvested at the end of October. It is also capable of yielding as much as 20 ounces per plant.

An increasing number of growers prefer to grow Bubba Kush indoors because of its large, dense buds. If you attempt to grow it outdoors in a moist climate, there is an increased risk of disease. The most common is bud rot, which thrives in wet conditions.

When grown indoors, Bubba Kush’s flowering time is approximately 8-9 weeks. You can expect medium buds and a yield of 15 ounces per square meter planted.

We spoke to indoor growers who placed feminized Bubba Kush seeds in Jiffy Pots. They told us that these seeds germinated within three days. They later became dark green plants after remaining in the vegetative stage for a month. After nine weeks, the plants produced their indica-dominant fat buds, which were laden with resin glands.

2 – Growing Bubba Kush with Hydroponics

The use of non-soil growing mediums, also known as hydroponics, has become extremely popular in the world of marijuana. Although you should try to use soil for outdoor growing, it doesn’t always make sense indoors for the following reasons:

  • Increased susceptibility to pest problems. Once a disease or pest gets into your indoor grow room, it can spread very quickly and devastate your crop.
  • You need to purchase excellent soil because its quality has a considerable influence on the quality of your harvest.
  • It isn’t always possible to recycle soil.
  • Monitoring soil pH is essential and challenging to do (as you’ll find out in section #6).
  • Determining the right amount of nutrients also requires a lot of work (as you’ll see in section #3!)
  • In contrast, a hydroponic system enables you to control nutrient and pH levels more precisely. Once you understand how it works, you enjoy total command, which boosts the quality and quantity of your harvest.

The Best Hydroponics Systems for Growing Bubba Kush

If you are a new grower, it is best to choose a ready-made system that comes with everything you need. Although there are several hydroponics methods, a Drip System is one of the most popular. This enables you to choose between a variety of growing media. It is also an excellent option if you are growing on a large scale.

It involves adding individual drippers to each plant’s growing medium. These drippers deliver equal amounts of oxygenated water nutrient solution to each plant. Any solution that doesn’t get absorbed by the plants is drained into the reservoir and pumped back through the dripper system.

One of the big advantages of a Drip System is that you can enjoy several harvests per year when you grow your Bubba Kush indoors.

You also have full mastery over the amount of nutrient solution received by each plant. Finally, you maintain control of the watering schedule, which means you can water your plants according to their specific needs.

3 – Feeding Your Bubba Kush Plants

The Nitrogen (N), Phosphorus (P), and Potassium (K) rule applies to all plants, and Bubba Kush is no different. This particular plant also needs calcium and magnesium during the vegetative stage to ensure it develops properly before flowering.

In addition to the above, it is advisable to use non-mineral elements such as carbon, oxygen, and hydrogen. You also need to provide adequate amounts of Sulfur, Manganese, Silicon, Chlorine, Molybdenum, Copper, Bore, and Cobalt.

Soil vs. Hydroponics

Nutrients are more of a consideration when you grow indoors using a hydroponic system. If you grow outdoors, you can use the ‘super soil’ mixtures we discussed in #4.

Once you use these types of soils, there is little need to add nutrients. All you need to do is check for signs of nutrient burn or a deficiency now and then. It is essential that you also ensure the plants are adequately watered too.

With hydroponics systems, you can also purchase a premixed powder or liquid solution. However, you will need to take more care when adding nutrients. It is advisable to pay close attention to the pH and Electrical Conductivity (EC) readings. We will discuss pH a little later, so let’s briefly talk about EC.

The EC reading tells you how strong your solution is and the number of nutrients in the water. Ideally, the reading should be between 0.8 and 2.0. You can use the 500 or 700 scale to determine the parts per million (ppm) reading of your solution.

Once you have the EC reading, multiply it by 500 or 700 to get your ppm level. For example, an EC reading of 1.4 would mean 700 ppm using the 500 scale and 980 ppm using the 700 scale.

It is best to err on the side of caution and use a lower amount of nutrients at first. The ppm of your nutrient solution should increase as the plant grows. Aim for around 300 ppm at the beginning of the vegetative stage. Gradually increase this until you are over 1,000 ppm, when you are close to harvest time.

4 – Creating a Super Soil for Your Bubba Kush

Although you can purchase premixed soil, it is fun to try and create your own organic super soil. The key is to understand the types of soil amendments you can add and how they impact your soil. For example, bat guano is high in nitrogen, bone meal is high in phosphorus, and wood ash is high in potassium.

In fact, with nothing more than an organic base material such as peat moss, compost, and an aerating agent like vermiculite, you can ‘amend’ the organic soil your Bubba Kush is growing in.

Simply create a base mix by combining equal parts of your compost, vermiculite, and peat moss. The base should make up around 20% of your total mix. Next, add kelp meal, mycorrhizal inoculant, and humic acid to establish a population of fungi. Fungi develop crucial mycorrhizal relationships with the plants’ root systems.

You also need to establish a bacterial population to break down complex sugars and convert them into micro and macronutrients. Adding bacteria also helps boost your plant’s immune system and increases its ability to fight off disease. Add bat guano and worm castings for this purpose.

The final step is to add extra-macro and micronutrient sources. Examples of these include Epsom salts, dolomite lime, azomite, bone meal, and rock phosphate. These additions bring magnesium, phosphorus, nitrogen, potassium, and other nutrients to the table.

5 – Climate Considerations for Bubba Kush Marijuana

The ideal temperature range varies slightly, depending on the strain. Most marijuana plants prefer relatively warm temperatures, close to 70 degrees Fahrenheit. Some strains can even thrive in the high 80s.

As for Bubba Kush, it grows best in a temperature range between 68 and 80 degrees.

You can bump this up to 82 degrees during flowering. When the lights are off, make sure the temperature doesn’t fall below 60 degrees.

If the temperature is too low, evaporation through the leaves is reduced. The suction force, which absorbs nutrients via the roots, becomes smaller, and necessary nutrients that aren’t absorbed stay in the growing medium and disintegrate in the root environment. If the growing medium’s acidity level is high, the roots don’t function as well, which causes a reduction in absorption. The result is slower growth.

As for humidity, try to keep it in the 60–70% range during the vegetative stage. Too many new growers maintain a humidity level of over 80%, which is simply too high. It is important to remember that excess moisture increases the chances of disease. Reduce the humidity weekly, and by the middle of the flowering stage, it should be close to 40%.

6 – The Importance of pH

Also known as Potential Hydrogen, pH levels measure the acid-alkaline balance in soil and water. The pH scale ranges from 0 to 14; 0 is the most acidic substance, while 14 is the most alkaline. 7.0 is a ‘neutral’ reading and is given to pure water.

Marijuana plants prefer slightly acidic soil. Ideally, growers who use soil as a medium should keep pH levels between 6 and 6.8. If you have a hydroponics system, it should be in the 5.5 to 6.5 range.

The pH range of your growing medium dictates how well your cannabis plants absorb nutrients. For instance, an acidic medium enables better absorption of Manganese. Also, the nutrients you add or subtract have an impact on pH levels. You should invest in a pH meter to measure the levels of collected runoff water.

Once you know the pH, you can take action as necessary. For example, if the medium is too acidic, use lime to balance things out. If it is too alkaline, use soil sulfur to make it more acidic.

Commercial potting soils and topsoil are already pH-balanced, which takes a lot of guesswork out of things. If you purchase a hydroponics medium such as Rockwool, you have to soak it in a solution with a pH of 5.5 for several hours.

7 – How Do I Know When My Bubba Kush Is Ready for Harvest?

Knowledge of when to harvest marijuana at the right time is something you only gain with experience. You may have read the phrase ‘trichome-covered buds’ multiple times, for example, but what does it mean?

Sure, you can use flowering time as a guide and prepare to harvest your Bubba Kush eight weeks after flowering. However, this isn’t a guarantee of an accurate result because plants mature at different rates. And that even goes for those in the same crop.

The pistil method involves waiting for at least half of the plant’s white hairs to darken and curl in. They should attain a reddish/brown color. At this stage, you could harvest, but it’s too early if you’re seeking a genuinely potent crop of Bubba Kush.

Instead, wait until around 70% of the pistils have turned brown for premium THC levels. If you wait until the 80% mark, you enhance the sedative and calming effect of the strain. Once you go beyond this point, you have missed your opportunity, as the resulting weed will be weaker.

The trichome method requires a magnifying glass or a jeweler’s loupe. You are looking for the little mushroom-style trichomes that grow on the buds.

When the trichomes on your Bubba Kush are clear, your weed is NOT ready for harvest. If you see a majority of cloudy trichomes with mushroom heads, it is time to cut down your crop!

8 – Choosing Between Wet & Dry Trimming

When harvest day arrives, you have come a long way! However, there is still a lot to do before you can enjoy a potent and satisfying smoke.

One of the most important tasks ahead involves trimming the plants. You need to remove as many leaves as possible, or you will suffer from a weaker and harsher smoke. You will also need to decide whether you want to attempt ‘wet’ or ‘dry’ trimming.

Wet trimming involves getting the job done soon after cutting down the weed and before it has the chance to dry. It is a better method for novices because it is easier and more practical.

When the plant is wet, it is easier to reach in and remove a full leaf stem. Also, if you wait too long, mold can appear. Mold tends to appear between the stalk and bud at this point, but wet trimming eliminates the problem.

Those who practice dry trimming do so to prevent the nugs on their Bubba Kush from drying out too quickly.

When you take your time drying, you end up with a smoother and more pleasant smoke. That is, of course, if you remove all of the leaves! For many growers, wet trimming is not an option, so they have to remain patient and wait.

Ideally, you will use both methods and derive their full benefit. After harvesting your Bubba Kush, trim away big sugar and fan leaves. If you keep the smaller sugar leaves, you protect the buds and their trichomes while reducing the risk of mold.

Once the branches are thoroughly dried, begin trimming the rest. We recommend keeping these leaves because they make excellent additions to edibles and tinctures. In our opinion, the Bubba Kush plant is too valuable to waste!
