Thanks for the tip Sake! I normaly use google to search forums, but you provided me with great links!
So I'm thinking a 1 to 1 ratio of H2O2 to H2o for a couple mins should do the trick. As far as I know I have fairly hardy plants. I guess I'll find out. I see archarnis(sp?) will die, but then again what doesnt kill it(ferts, flourish, ect)? And I dont like/grow that crap.
