Using a t96, tap water, and following the clonex solution exactly.. and dip cuttings into the gel about 2'' deep I get very nice 4-5'' roots and lots of them... loving this t96. BTW I don't even use the humidity dome.. I have a 3x3x6' tent flipped on it's side with my T96 in there inside of my mother room.. I keep the door flapped shut but not zippered which keeps the humidity in there up a little compared to the rest of the room. Follow the directions on the Clonex... and use tap water.. let the solution run for 24 hours before you put any clones in there.. Make sure you wash the whole cloner in the shower before using it at all.
