This is a personal choice , if you think your buds are dusty and dirty from being grown outdoors I would advise you "bud wash" them . The easiest way to do so is to get yourself a decent sized bucket like a 5gallon one and fill it with distilled water . take your buds and dunk them in the water swaying them back and forth quickly and with a fair bit of force . Once you have done this hang the bud to dry immediately and hang it somewhere with humidity as low as you can humanly get it . I would even get a dehumidifier and try to get the humidity to like 10 % in your curing space . I say to get it as low as you can due to having washed your buds your going to have alot of extra moisture and you dont want mould at this point so its best to be preventative . They should only stay really moist for the first 24 hours or so then it will greatly reduce every day until you're ready to put them into jars for the final curing steps . There are a variety of different ways to do a "bud wash" but the way I described here is the easiest way to do so . You can also look up various techniques on youtube from a grower called Lex'sWorld or Pigeon420 . I hope this information helps you understand the choices you have in that you can bud wash but you just have to be prepared for it and know the risks your running when doing so . All in all your grow is really well done . -Happy Growing!
