Boveda users have many different ways of using Boveda. Some like myself, dry slowly trying to keep the RH in the area about 50%. Then cure with Boveda immediately. While others don't cure with Boveda but add it in for storage. We've heard a trend in the US with large growers who use the 58% to cure but then the 62's to store. The only part of your technique is the time spent in the "risk" zone which is 65% or over. 65 is where microorganism growth begins. In the end, I'd say that yes, you're good at 59%
