Understanding Brix Readings
Now we understand how plant sugars can improve cannabis yields and how a brix refractometer can tell us the amount of sugars in the plant . The last question to be answered is what a high and low brix reading means . Low brix readings for cannabis are in the range of 0-12 and usually indicate high nitrates , poor nutrient density , and an overall unhealthy plant . Nitrates are usually distributed in water with higher nitrate concentration . This means sugars are lower . That may cause a decrease in bud growth and an unhealthy plant . A watery brix reading also indicates other mineral deficiencies that can increase insect attack and disease . Low brix further indicates more stress for the plant . Low brix tells growers a change to the growing conditions is needed and may show pest control measures need to be taken . Average brix levels are typically in the range of 12-20 . An average brix level tells cultivators the plant is doing well . It will also allow you to slowly increase brix levels to produce the tastiest and heaviest yields .
Higher Brix Measurements
High brix readings are typically in the range of 20-30 . A high brix reading shows a plant at the peak of its health . These plants may grow faster , weigh more , and have higher-quality buds compared to others . For breeders producing seeds , higher brix indicates high-quality seeds will be produced . These seeds typically germinate better , grow stronger , and give the best value to the buyer .
Conclusion
Brix is an easy method of understanding how your plants are performing during the grow . Brix gives the grower an indication of how healthy or unhealthy the plant is . It allows growers to get a glimpse into the future of the plant ’ s lifecycle . It is important to have your brix level at 12 to ensure the plant is poised for a good yield . By adding supplements to the watering schedule , the plant can easily go above a brix level of 20 — the most desired level on the cannabis market .
By using a simple brix refractometer , growers can expect the heaviest and tastiest buds they have ever produced .
