So i have started clones about 10 days ago in rock-wool cubes with rooting hormones and they are still not showing any signs of growth, about 2 days ago i remove the humidity dome completely since they where not showing any more signs of wilting when off for long periods of time, i figured this was good sign but still cannot see any roots coming out the rock wool and no new growth. They look very healthy though, so at this point am i just inpatient or their is something that is stopping roots from growing out the rock wool?
