Elizabeth - the game was crappy. I was hoping the falcons would win. Anyway - there are a few things that need to be taken care of with your plants. Light, temp, relative humidity, nutrition, and air circulation/exchange. Let's leave drying and curing for another date. Any one of these factors - left unchecked - can mess up your grow. Anyone on this boardn with a few grows under their belt will tell you - they have all messed it up once or twice. The losses can be staggering especially give the time it takes to nurture your crop from start to finish. Learn. There is no magic bullet but there is a mountain of information. Take what you learn, apply it to your grow, pay attention to the results. Next grow should be better. As far 27%RH you'll get a lot of answers depending what the strain is and time into the grow cycle.
