You won't really need to do anything extra after the bucket method. The bugs will release even if they're feeding.I’ll look that method up, I imagine making it all into bubble hash with a serious amount of rinsing in RO and ice Cubes will help too.
A lot of people worry about knocking off Trichomes when they're doing a wash. As long as your water's not cold you're not gonna breaking any off and being reasonably gentle with the Wash.
I've only washed outdoor plants. And I know one thing........ I will always wash outdoor girls! LOL!
I'm like you man! I'm just leary as hell of spraying any sort of 'pesticide' on my cannabis. As you said, that's why you grow your own and that's exactly my reason also.
Like with my stupid gnat infestation of my previous run, at least you know what to do now to avoid another infestation. And just like with my gnat infestation, It wasn't something you already didn't know! I didn't isolate that Oly compost and make sure it didn't have any problems. I'm not doing that again! It cost me production wise and monetarily trying to rein those fuggers in!
