From what i have gathered candida was one of the first of these, but is no longer match to newer strains. Candida buds look like the shittiest weed you have ever seen.
And compare to this swiss dream CBD for example:
The taste on that was best weed i ever smoked hands down, it had a nice purple coloring, but not all turn purple like this. There is also a purple version of this.
I havent grown other CBD strains, so there might be better than this around. This swiss dream did stay quite small, so the yield wasnt great, but was very nice quality. Complately different world from what i have seen of candida buds
