Clones will Not Root

I built myself an aerocloner using the widely available instructions. My first try was a success. 100% success ratio. That was also in September. I've tried twice now and am 11 days into my 2nd try. The clones I took are mostly all still green but still no roots. The water temperate is at 68.5 in the cloner. I am using straight tap water. Could the temperature be the problem? Im doing everything pretty much exactly the same and none of the clones are rooting.

Some strain's don't take that good to being cloned. have you taken clone's of that strain? It could just be a few more day's , just wait it out if they are still alive.

If they havnt keeled over, just be patient...theres a ton of Info on here regarding cloning as I'm sure your aware..i was recommended to use root riot plugs by one of.the guruz on here..personally my advice would be too clone during the cooler part the day....have a lil patience and be tempted to touch them... If there not wilting ..more time

Warmer will help. The quick clones in the summer? I run about 78f.

Going in tune with the comment above, if clones take longer too root;

-Warm up the temps
-Increase humidity

Clones love jungle type environments

Ok, I will give it some more time. Question, does it matter how big of a clipping I use as a clone? Is it that import that I am only including the top node and a couple inches below? Some of the clones I cut off of my mothers were like 6-8" tall.

Neither will the missus.
Seriously though its the water temp, bump it up to 80-85.
