I had to bud wash for the first time in about 10 years. Had a minor thrip issue during flower, so I used Diatomaceous earth, instead of an insecticide (it worked quite well). You don't want to smoke DE (or breath large amounts of it). So bud washing was necessary to get the residual off (plus the thrip residue). Of course if I look back at the Mexican ragweed we used to get in the 70's, aside from the copious amounts of sticks, stems, and seeds, it had, bugs of all kinds, butterflies, feathers, even found a dead bird in a brick once! But we smoked the weed.
