I have to add my opinion which I can only base on one of there strains.
Red Dragon was a very nice strain. Very little pheno's. Could of been he Seeds I got but only really got one pheno to show up. Smell was amazing and end date was the same for all. They were feminized seeds and under severe stress they didn't herm. By severe I mean that a High pressure aero line running 60PSI froze and burst from the cold when the heater went, and then had a cooling problem right after giving them a nice 109 degree day and roughly around 34 or less degree night. They didn't yield much that run due to a few failures and a jackass that did check on things like they were asked to do. But yeah, still had very good luck with them none the less.
one thing I have used as a sign of good breading is uniformity, quality and yield. all attributes stuck out at me when I grew them and I was impressed since I have yet to find another strain that was that consistent.
Maybe that just was a fluke. I only used them once and for one strain, I will find out when another arrives and will try to venture back and leave another post.
