Royal Runtz cannabis plants can be grown successfully even by novice growers. This strain grows medium to tall, so whether it is grown indoors or outdoors, it requires ample space to thrive. This strain can reach heights of between  4-6 feet tall, which means you will need to give it enough space to grow laterally and vertically to hit your anticipated yields. This strain performs better indoors than outdoors, but will grow similarly to an indoor plant if you have access to a greenhouse. While some cultivators prefer to grow in natural sunlight and fresh air similar to that of the Mediterranean, others prefer the more predictable, controlled environment of growing indoors. Ideally, the temperature should be between 70 and 85 degrees Fahrenheit, with relative humidity between 65-70%. If you are going to grow this strain indoors, you will need to replicate the ideal climate to hit its maximum growing potential. If your local weather is similar to these conditions, your crop will perform well outdoors. However, setting up your grow inside will help you keep the right lighting, humidity, and temperature. To increase your yields, utilize Sea of Green (SOG), Low-stress training (LST), and Screen of Green (ScrOG) techniques. Royal Runtz plants have heavy buds that tend to bend the branches of the plant without support from screens or stakes. You will want to add these techniques to your training regimen to ensure you get to harvest with healthy, THC-rich buds.
