hey man. if you're going to be growing for a while i highly suggest you try washing for yourself. maybe wash half and dont wash the other half and compare the results
personally I wouldn't bother with washing if you're growing in indoors unless you have mildew or excessive dust present at some point during the grow all of which can be avoided easily indoors. animal fur is notorious for working its way deep inside of buds and i dont think a rinse is gonna get that out. its just not really feasible to keep the fur off the buds if theyre gonna share a space.
outdoor bud should be washed at harvest 100% of the time.
washing, done correctly, is not risky, and has no negative effects whatsoever. it won't remove potency, flavor, or smell. won't add to it either.
