8 Tips for Growing Banana Kush Cannabis: Grower’s Guide

If you are fortunate enough to live in an American state (or in Canada) where it is legal to grow weed, it is now possible to grow your favorite strain without fear of arrest. This is why we have increased our range of guides that offer steps and tips on cultivating cannabis. In this article, we provide a growing guide for Banana Kush.

Remember, you could end up growing a different Banana Kush strain each time if you change a few things during the plant’s life cycle. Even something as simple as harvest time has a huge effect on how your weed looks and tastes, not to mention the different type of high.

Tip #1: Strain Review – What to Expect from Banana Kush

Banana Kush is a Californian strain and is a cross between Skunk Haze and Ghost OG. It is an Indica dominant (60%) hybrid that smells and tastes like fresh bananas. With a THC content ranging anywhere from 16% to 27%, this is a strain capable of being extremely potent.

As its effects hit hard and fast, novice smokers should be cautious and use only a small amount at first. If you are feeling stressed, Banana Kush is ideal because it helps you relax, unwind, and occasionally, enable you to slip into a daydream state. Once the full effects take hold, you will be couch locked and very hungry due to a serious attack of the munchies.

It is a popular medicinal strain and is used to treat appetite loss, stress, anxiety, chronic pain, and depression. As Banana Kush is so powerful, it can cause dizziness and occasionally exacerbate feelings of anxiety and paranoia.

Tip #2: Difficulty Growing Banana Kush

Banana Kush’s grow difficulty is classified as moderate, primarily due to its issues with mold. The most common problem is powdery mildew, a disease that is found on the buds and leaves of Banana Kush, and many other marijuana strains. You’ll normally discover it on the lower branches of plants because there is less airflow, lower exposure to light, and greater humidity levels.

It is easy enough to spot as it manifests as a white powder on the surface of the leaves. If you spot it, treat it ASAP because it spreads extremely quickly as it makes its way to bud sites. Prevention is better than cure, so prune your plants regularly, keep the humidity level in the grow room down, and spray your plants with organic products.

If you discover powdery mildew, mix a tiny amount of 3% hydrogen peroxide with water. The resulting solution sterilizes the plants and eliminates the mildew. It is a royal pain, but it prevents your entire crop from being infected.

Tip #3: The Best Growing Techniques for Banana Kush

With Banana Kush, it is all about hydroponic growing. Here are a few tips if you decide to grow your weed using an inert growing medium:

  • Make sure all equipment is sterile. This includes tanks, reservoirs, filters, pipes, and any other physical part of the system. If everything isn’t properly sanitized, pathogens such as root rot can take hold and spread rapidly. Disinfect your equipment with hydrogen peroxide and isopropyl alcohol regularly.
  • The water running through your system should be 65 degrees Fahrenheit to ensure good nutrient absorption and also to keep algae at bay.
  • Begin with clean, pH neutral (7.0) water. Use a reverse osmosis (RO) system if necessary. Keep the pH of the soil between 5.5 and 6.3.
  • Invest in a proper lighting system. If you have a small grow room, CFLs are okay. If your grow room is on the larger side, get HID or LED lights.
  • Air must be moving around properly in the grow room as good air flow keeps temperatures in check, reduces the risk of excess humidity impacting the plants, and prevents the smell of weed becoming too noticeable!

Tip #4: How to Get the Highest Banana Kush Yield with CO2

One expert tip is to increase the level of carbon dioxide (CO2) in your grow room during the flowering stage. Banana Kush’s yield is classified as moderate as it provides up to 18 ounces per square meter planted indoors. However, if you add the right level of CO2, you could boost your yield by around 20%.

When you introduce CO2, it increases the amount of light that your plants can use. As you know, the longer and more intense the light exposure, the fatter the buds. Normally, you can run into problems with light burn if you use high-powered lights such as a 1000W bulb or strong LEDs.

It is important to note that merely adding CO2 on its own is not enough. If your plants are exposed to a moderate light intensity, adding carbon dioxide to the room will achieve nothing. You should only use this tactic if you believe your Banana Kush plants have already maxed out on light.

When you use CO2, make sure you seal off the grow area and pump enough of the gas into the room to significantly alter the CO2 ppm (parts per million) in the air. Natural CO2 levels in the air have increased to almost 400 ppm. You will need to maintain CO2 levels of around 1500 ppm in a room with extremely bright and intense light. One final point: Exposure to high CO2 levels is harmful to humans so be careful!

Tip #5: Feeding Banana Kush

If you want to get the best out of Banana Kush, it needs to be fed heavily. While it is common for novice growers to overfeed their marijuana plants, it is less of an issue with this strain. As you probably know, light is the real food for your weed, because it is what your crop turns into energy through the process of photosynthesis. This energy fuels vegetative and flowering growth.

As well as ensuring your Banana Kush plants receive enough nitrogen, phosphorus, and potassium, you must not forget micronutrients such as zinc, manganese, iron, copper, boron, silicon, and cobalt.

A bonus tip is to add a spoonful of molasses heavily diluted in water near the end of the flowering stage. A teaspoon per gallon every time you water your plants should be enough to improve flavor and fatten up those buds. Molasses works just as well as the most expensive supplements and costs a fraction of the price.

Tip #6: Should You Grow Banana Kush Indoors or Outdoors?

You can attempt to grow Banana Kush outdoors. It should be ready for harvest in early October and provide up to 21 ounces per plant. However, it will thrive in an indoor environment where you can remain in full control of climate conditions. Remember, pruning and training this particular plant is essential, as is ensuring the grow room has excellent airflow.

Tip #7: Banana Kush Flowering Time

Banana Kush’s flowering time is 7-8 weeks. There are several ways to tell if your marijuana strain is ready for harvest. The most common is the pistil and trichome methods, but you can also take a look at the leaves to determine when the crop is ripe. Once you get towards the end of flowering, take a close look at your plant’s leaves.

In the earlier stages of growth, yellow leaves can be a sign of nutrient burn or a deficiency. Late into the flowering stage, however, they are often a sign that the weed is ready for harvest. This is especially the case if leaves begin dropping off by themselves. If you use fertilizers, leaves won’t fall off.

Curling leaves is another potential sign. This is because marijuana consumes less water near the end of its life cycle. Make sure you examine your plants if you see curling leaves to make sure it is not a sign of disease or pest infestation.

Tip #8: Best Climate for Growing the Banana Kush Strain

Regardless of where you decide to grow Banana Kush, it performs best in a stable environment where the temperature is in the 68-80-degree Fahrenheit range. The most important thing to consider is relative humidity (RH). As it is a strain that grows thick, Banana Kush is susceptible to mold and powdery mildew in excessively humid conditions.

During the vegetative stage, keep the RH in your grow room to around 55-60%. Lower it by a few percent each week. Make sure that the RH is around 40% while flowering to reduce the risk of mold growth.

Final Thoughts on Banana Kush

Banana Kush is unquestionably a treat for the senses. The banana and tropical fruit scent lure you in, and once you have had a sample, you will find it hard to stop! This could become an issue if you find a version with 27% THC!

In any case, Banana Kush grows best indoors, and the main problem you will face is the possibility of powdery mildew. Keep the grow room temperature in the 70s for the most part, and reduce humidity all the way to 40% or even less during the flowering stage.
