I haven't had any issues with germination..........probably close to 96+% overall after sprouting maybe 200 seeds altogether. Hermies, on the other hand, can be rampant depending on the strains you grow. Some are riddled with hermies, others have been absolutely clean. Most hermies I've seen become apparent around weeks 3-4 in flowering, low on the plant off the main stem- this is where hormones tend to concentrate highest.
