started out using rw cubes and changed to Rapid Rooters, to much salt in RW for the long run. Using Roottech gel atm and not real impressed with it, looking forward to changing over to Clonex. We use tap water dropped down to 6.0 with a drop or 2 of ST. Tray, heatmat, dome, temp range 75-80 and couple 23w daylight cfl's overtop on 24/7. Survival rate over past year or so about 90% or a point or 2 higher :thumbsup:
