So, wash out the grow racks, treat heavily with systemics, flush with
contact, what the hell some throw some neem and phytosan on just for
fun

AKA Nuke them all.

got it, no wonder they are such a freeking pain, in the past I could
manage to keep them from doing serius physical damage to my plants
(yeah yeah I know about virus and all that) but could not manage to
elimniate them.

I will have to make a dedicated effort

Thanks
