Oops , I didn't read lower , your note is telling that's a mosaic , sory !

 

Me too I'm optimist :) Maybe the KC sold at BH is better than KCS , we'll see how it work , Chris Schur is testing the one sold at BH :)

 

Here we usualy have  60 to 80% of humidity , compared to your site , it's very humid ;) and last friday the temp was ~ 5°C but at noon it was ~20°C , we have a big diffference these times in temps at days and nights. 

 

Now it's 3:43 am here ... time to go bed ;)

 

Thanks Wei-Hao !

 

Clear skies !

 

Dom :)
