It is not possible to harvest hops automatically without modifications to IC2. The harvest function in the mod's code is directly tied to the player's right-click button (even on servers). Any other action will break the crops and will not drop the hops. I'd suggest removing the challenge from your profile.

P.S. are you able to unlock the Nuclear Reactor page? I can add more information about the explosion radius etc.
