pyrethrum (spidermite knockdown) is the one i use from Dr doom its natural comes from carnations etc...mostly widely used ....i use it one spray at the base of the pots and everything dies it can be used 1 day away from harvest so...readup before you call it poisons etc....

These little buggers breed their larvae in the grow medium and they eat the roots... I need something i can spray onto the hydroton and maybe even something i can put in my buckets to kill them.

Yeah man they are tough fuckers to deal with. Yellow Sticky pads and Hot Shot Pest strips get rid of some of the adults but those fuckers have fuck fests on your medium and plant larvae. I been trying to get rid of them with predatory nematodes, a microscopic ring worm that eats critters and larvae . They pretty much fucked up two of my Larry OG's now they are weak and will be small yielders.
