My two cents from what I read-haven't done it yet but read as much as I could. 2-1/2 minutes for vaporization, disconnect current, wait 2-1/2 minutes more, remove wand, re-seal hive for 10 more minutes. Think that's the instruction. I built a top mounting shim/box and plan on doing it that way but just did FA and we're starting what looks to be a very good fall flow with lots of knapweed, goldenrod and aster everywhere here-rains been reasonable every few days-usually at night. Once we get to the end of the flow near the beginning of October, I'll be doing the 4 treatements over 20 dyas and a final, hopefully broodless after Thanksgiving.
