I have had good luck with KC Brains. I find the strains to be stable. Most of their strains yield well and are easy to grow. Grew some SwissXT last fall. It was a nice berry skunk type plant. I thought I had pictures, but I couldn't find them. Their Northern Lights would be a great strain for noobs, though I thought it was a bit weak potency wise. The yields were great though. I have grown a few singles of a few other strains. The KC33 was decent. It was a nice mellow lemony sativa.
I have grown a lot of the Cali Special. It is one of my favorite strains for taste. I've been looking for that orange taste for the last year or so, and I finally got it. I need to run some more and look for the whiskey sour pheno. That used to be one of my favorites. Potency wise, it is similar to a skunk or ak strain. Good daytime weed for me.
I would say it is an above average yielder. My eye scales tell me around 2.5-3 ounces, but that was in a two gallon container. I think the yield descriptions may be for outdoor. I have seen some monster TNR outdoor growlogs.
