its called root or die ...easy to tell after a few weeks...keep medium moist not overly wet ,,,,keep it warm with steady temps,,,,keep humidity high,,,,keep light level low...yeehaw......clones don't live too long without roots unless in refrigerator.....then they last a month or so... I generally see lower leaves start to yellow a bit and plant stretch some...I hate peat pucks they suck ass!!!!!!!!..perlite rules over any cheap medium I have used.. and I tried em all just about .......unless there is something new and overhyped...home depot has big bags like 16 $$$$ last average guy long time......perlite is just about foolproof and has perfect structure for fast root development......holds moisture but has airspace ,,,,almost impossible to over water in right container,,, but doesn't dry out fast ...cant beat that!!!!!!!!...I wish you a high success rate man ..good luck/
Ok so don't mist the clones only keep the pellets moist right

...solo 16 0z cups with perlite and holes in side near bottom ,,,,as bottom holes sometimes seal shut and don't drain I have found...
