Surviving Load Shedding: Tips for Indoor Cannabis Cultivation in South Africa

Updated: Aug 11, 2023



South Africa has been experiencing frequent power outages, or load shedding, due to its struggling power grid. While this can be inconvenient for most people, it can be particularly detrimental for indoor cannabis cultivators who rely on electricity to power their grow lights and other equipment. However, there are ways to mitigate the impact of load shedding on your cannabis plants.


Firstly, it's important to understand the load shedding schedule in your area and plan accordingly. Make sure you know when the power will be cut and for how long, and adjust your watering and feeding schedules accordingly. For example, if you know that the power will be out for a few hours in the evening, water your plants earlier in the day so that they have time to absorb the moisture they need.


Secondly, consider investing in a backup power source such as a generator or battery backup system. While this can be costly, it can provide you with peace of mind and ensure that your plants aren't without light and ventilation for extended periods of time.

Another option is to use low-power LED grow lights instead of traditional high-power HID or HPS lights. LED lights are much more energy-efficient and can save you money on your electricity bill, as well as reduce the impact of load shedding on your plants. Additionally, LED lights produce less heat, which can help keep your plants at the optimal temperature even during a power outage.


Lastly, consider using natural light to your advantage. If you have windows in your grow room, try to position your plants so that they receive as much natural light as possible during the day. This can help supplement your grow lights and reduce the amount of electricity you need to use.


In conclusion, load shedding can be a challenge for indoor cannabis cultivators in South Africa, but it's not insurmountable. By planning ahead, investing in backup power sources, using low-power LED lights, and utilizing natural light, you can help ensure that your plants stay healthy and strong even during power outages. Remember to always prioritize safety and follow any relevant regulations or guidelines.
