I'm doing White Widow, StarTrek (Stargazer x Trainwreck), & Mazar i Shariff. Out of the 3, the Widow & Trek have by far been the best. White Widow is very compact with lots of budsites, easy to grow (loves nitrogen), and the buds and leaves are frosted the second they appear during flowering. She started flowering sooner than the others which is also a plus, as you won't go too late into fall. The StarTrek is another good one. The only girl in my garden that I didn't top, and I'm glad too. Medium height, with excellent xmas tree like branching and frosted buds that are currently coming off somewhat fruity, although as they mature they will get more of that dank trainwreck flavor. The fruity flavor has to be some of the Star genetics. In the end, it kinda comes down to what you're looking for in a strain. There's SO MANY great new hybrids out there from various seedbanks. You'll have hundreds to sift thru and choose from. Go look around, and most will tell you what is recommended for outdoors, what it's growing specs are, and all the characteristics of that specific strain.
Hope this helps!
