thats odd. i usually take cuts, dip in clonex gel, use room temp water to start, a lil clonex solution for aero cloners and turn it on. i come back in a week and always have roots. 100% now with over 60 done.
If you are referring to the slime problem as odd it basically boils down to your city water...You either have it in it in your area or you don't (thats what the icmaggers say anyways).
