The history of Banana Runtz seeds remains unidentified, but some cannabis connoisseurs believe this is the same strain as Banana Punch. Solfire gardens are the original breeder of this magnificent and high-profile strain.
Experienced growers recommend the paper towel method to germinate your Banana Runtz seeds. Not only is the technique effective, but it is also easy and cost-effective. You will not incur extra costs as the materials needed are available at home. Below are steps to follow when using the paper towel method.
Feminized seeds are an excellent choice for growers looking for practicality and simplicity. These seeds only produce female plants, unlike regular seeds, which aren't gender-specific. When growing feminized seeds, you are sure they will bloom into bud-bearing plants. However, with regular seeds, it is necessary to cultivate approximately twice as many plants so you have enough left after removing male plants. Feminized sees allow you to use your growing space better and save on substrate and products like fertilizers and insecticides.
Banana Runtz seeds produce tight, dense buds that can develop into various colors. If you cure your stock correctly, you can expect anything from neon green colors to vibrant purple tones. Growing the Runtz strain is never seamless for beginners; it requires a moderately skilled hand. That is because the Banana Runtz strain has rapid growth and can increase in size quickly during the flowering stage. The flowering time of this strain is approximately 70 days, while the harvest period is around 80 days after flowering. Using techniques like topping and trellis nets can help you produce high-quality cannabis.
You can produce Banana Runtz seeds in a controlled environment or an outdoor garden. Each method can reward you with moderate harvests.
When cultivated indoors, this strain grows only about 4'5 ft tall and yields about 16oz of bud per plant.
The Runtz strain can reach a height of 5'9 ft when grown in an outdoor garden. The yields are a bit higher – 18oz per plant.
Expect yields of about 18oz when growing the Banana Runtz strain outdoors and approximately 16oz when cultivating them indoors. Using a trellis net for your indoor cultivation can help you increase the yields. Another way to increase this strain's general yield is by fimming and topping.
A hydroponic setup is the best option for cultivators who want to speed up the growth of Banana Runtz seeds. On the other hand, mineral-rich soil is best for enhancing the flavor and fragrance of your buds.
Banana Runtz seeds flourish in a warm and sunny climate. But this strain is resilient and can adapt to growing conditions.
The Runtz strain is highly resistant to mold but may be susceptible to other plant problems. These include pests and bugs, cannabis deficiencies, and diseases like root rot. Most of the plant problems manifest through the leaves of plants. For example, if your plants have inadequate nutrients, you will notice that the leaves have drooped and may also have brown or yellow patches.
It is essential to know the symptoms of root rot disease to establish whenever they are a problem. Identifying white powdery mildew can be challenging for novice growers. However, you can easily remove that by gently rubbing it off with a damp piece of cloth.
Banana Runtz seeds require an experienced hand to unlock their true potential. That means this strain is not suitable for beginners.
Topping involves cutting the top branches of your cannabis plant to its vertical growth and encouraging lateral growth. Besides helping you control the plant size, topping is an effective way to increase the yields of your Banana Runtz seeds.
Trellising uses metal, wooden, or plastic frames to support and organize your plants' growth. It may also involve draping square netting over a plant at specific growth stages.
Trellising is especially important for the Runtz strain due to its wild and vigorous growth. It ensures enough space and airflow, promoting fuller flower growth.
Fimming is a growing technique to increase the final weight of the buds. For this method, cultivators remove the new growth tip of a plant at the end of the stem or branch. To maximize your plants' yield, combine fimming with topping.
