I would avoid Herbies all together. I really like how they provide literature to guide you through the process and provide assistance when question arise, however a 25% success rate is far from acceptable results. If this is common, then by all means take this review with a grain of salt. But if a 25% success rate is not common then you should pay close attention and not waste your time, money, or efforts. After much reading and researching I followed their suggestions and literature to a "T." From nutrition, watering, humidity, conditions, etc. this was my experience a 25% success rate. Needless to say, I was extremely disappointed in the results and after reaching out to Herbies I was told there was nothing that could be done. Item shipped and arrived on time was well packaged but produced 25% of the quantity purchased. Just an honest review from a real experience that I hope can help someone make an informed decision and I will not utilize them in the future.
