Sounds like great intentional breeding goals Maha.and why it appeared there? I think it is due to diesel, which contain northernlightsskunk, dont know how much, and believe it or not, these genes of NLskunk found those little colombian genes in toms haze, and got it together, in this one pheno... it seems that nlskunk loves colombian haze.
for thaihaze hybrid project, such pheno is unwanted. I am done with any form of sour diesel for this project.
edit: it is apparent for me, that I cant exceed certain portion of indica. too much indica, and cross cant keep tropical quality. Tom Hill crossed haze with deep chunk and pine tar kush, and although these are known as very cerebral indicas, he said he got mexican-like effect, dirty and muddy, in contrast of smoking thai haze with high activity of all senses, high clearness of brain activity, no stoniness, dizziness or something like that.
too much indica crossed with haze equals the lost of tropical quality. talking about F1s.
thats why mindblower, grandfunk and juicy are so succesful, as mothers are from lines which were bred to have some indica properties, like shorter flowering time etc. but keeps strong thai high characteristics. not even close to haze. but very suitable for making thai haze hybrid which is not so long flowering, but still gives tropical quality of the effect.
Happy to hear you are finding success and it sounds like the lessons you have learned along the way have really made an impact.
Salute!
