Oh, and Boveda paks are fine as long as they are not crystallized, correct?I have heard that too. The idea, I think, comes from a research paper (pointed to if not funded by Grove Bags, naturally) that suggested that salts (the stuff in the Boveda is a mixture of salts) harm terpenes. However, as I recall anyway, the research is not that applicable because it was designed around direct contact between salts and terpenes, it did not actually measure the decrease of terpenes in buds inside a jar with Bovedas. Further, the study may or may not have used either the exact salts or anything like the degree of exposure to salts that would result from normal use of Bovedas. There may be something to the idea, but the study provided by Grove does not in my opinion prove it clearly for our application.
I have used Bovedas for a few years, and have never noticed any difference in terps. If there is a real impact in our application, I think it is small and not worth worrying too much about. Overdrying early would have a far worse effect on flavor than using Bovedas. I don't hesitate to use them when I think they would help. I have some now in the last of my Grove bags that overdried my bud. I expect that not too much damage was done, the bud still smells nicely cured - better now than when I put the Bovedas in a few weeks back.
FWIW. I think the big advantage with Groves is more to do with their gas exchange during curing - I suspect that they are permeable to oxygen which, if the bud is properly dried, allows continued curing without burping. The big advantage of Bovedas for comparison is that the humidity control works in both directions - if the jar/bag is too dry, they actually release water, if too wet, they absorb it. The Grove bags do not add humidity to the same degree, and they can add none unless the humidity outside the bag is higher than inside. In my humble of course, you may get different opinion elsewhere.
Given your travel plans, I think your best bet is to lay in a supply of Grove Bags and Bovedas. One way or another the combination should keep your harvest in good shape while you are away. I deal with the same issue with just about every grow, I am always trying to get the dry and cure sorted before the dearest and I take off for a month or so. Pain in the butt, but it can work.
I tried steaming some after they got crystallized but it didn't work.
