This is to the OP..
Clones root when they want to. I have taken clones from the same branch that have rooted a week apart.. It has a lot of variables such as temp, available C02 matters. You always think you have the secret but then next time you try and back to the norm.
I have upped my rooting times by running more humidity, little warmer temps and 1500PPM C02. That helped like a mofo, but even as I type this I am reminded that the batch before this batch of clones took 20 days to root out. I do grow OG, which has no where near the short rooting time of something like Green Crack but you get when I mean.. The one thing I have found to be true is tap water roots clones the fastest for me. Additives slow shit down, I have tried a few and so far always true.
P.S. FU by rep is the funniest thing I ever seen on RIU.. That is some anger right thar buddE
