sweet seeds which seed?

i want trainwreck, but my main goal for this auto run is max yielding my veg cab, so i looked on sweet seeds

devil /dark devil and devil2 say they have best yeilds with only real difference the flower time which i am doubtful on most seeds anyway,
are they any good?
so wondering for yield who would you go for? sweet seeds? or another breeder?
i have around 3ft head space so sativas are out

I find breeders are often accurate on their yields. For example if they say they yield very well they often do. Though nothing is a given growing from seed, bear that in mind!

Why not heavy LST? Trouble with most indica autos I find is that they stay smaller than the sativa. With bigger plants come more bud sites. So you could aggressively train a sativa leaning plant and create more bud sites.

For that I’d deffo recommend Blue Dream by fastbuds. Very forgiving plant with loads of bud sites! But there’s loads to choose from

I am growing my first sweet seeds autos next grow... But they will be smaller strains. Some of their new strains are supposed to be very good. I was once told that anything with gorilla glue tended to be easy to grow and naturally good yielding. So maybe gorilla girl or red gorilla glue by sweet seeds? Also some of the Mephisto sativa's along with Ripley's OG are supposed to be heavy yielders. And a lot of Dutch Passion strains are supposed to get big. With autos I find a lot of the time, big yields and big plants kinda go hand in hand.

Lots of god auto breeders out there with Sweet Seeds being one of'em. With limited space as you have, some lst is gonna be needed for most plants.
I use topping and lst to keep all my plants canopies at the height for optimal penetration etc. So I say, just pick one and plan on your favorite lst method. FWIW.. there's not many autos that aren't hybrids and seems they all wanna show their legs sometimes...

Well from sweetseeds there flashback#2 green poison sweet cheese sad and killer kush i tried all those and they were all good i especially liked the killer kush and sad
