eventhough clones dont have roots,by u constantly misting them your not allowing them to dry out alittle.mist them once a day and leave them in the humidity dome,if the humidity dome has droplets on it then u dont need to mist,i mist once a day and get 100%success,its that u want them to be encouraged to seek out roots and by keeping them misted ur making them feed by foliar and not really tryin to make roots.a few times i kept my clones constantly misted and two weeks later after bein cut off the mother,they would die off.its when they died,is when i cut back on misting,ive even had success with harder plants like a lilac witch is now throwing roots out.its my opinion that worked for me,maybe if u try it,it might work and might not.i also have them 2ft away from a 125w 6500k cfl wit a mogul base.it keeps the temp about 75 with 75% humidity level,its when i mist that makes it 100%humid.some ppl find it easier to do things a certain way and others will swear up and down that there is only one way to go.all im saying is with time and patience is when you will find a way that works for you.dont give up just keep hope,and one day you will enter your grow room and see that they have roots.it still gives me the giggles when i see them root.ive been growing since 2002 and ive been researching for years aproximatly 10yrs.
ps im 18 almost 19,seems young but im 100%serious,and im not a punk grower,i do it for the fun and excitement and plus its free smoke.my parents are real cool about it aswell.my mom cant wait till i harvest my current grow btw.
keep your head up and hope that today will be the day that u see roots.
