Bud boosters are supplements that claim to increase the yield and potency of THC-rich cannabis plants. Some popular bud boosters include fertilizers, lime, soil amendments, and heat treatments. Bud boosters are controversial because there is no scientific evidence to support their efficacy. Some people argue that they can be harmful if used excessively, while others believe that they can only marginally improve yields. Finally, many people dismiss bud boosters as gimmicks aimed at exploiting consumers who are desperate for enhanced weed quality.
