Thank you, can we tell by looking at young plants which are going to grow suitably judging from the leaf/structure, I've paid more attention this time on the leaf type/shape but there's not a lot to go on tbh.The pure indica don't react so well to 12/12 from day 1 because they stay really short and produce small amounts of buds, I've had some type of Bubba Kush I tried from seed in 12/12 and it made only 6g of buds and about 2/3 of this weight of sugary leaves to make some hash, it's a small return from 1 plant and you can't really stick too many of them together because their leaves are so wide, they overlap each other making shadow and water droplets who can make bud rot. That's why I prefer to grow plants with more sativa blood, it allows them to grow enough to produce decent amounts, on average in a 10L pot of soil, I can harvest +/-30-40g by plant, that's good enough for me without veg time. Plants with more indica are more in the 20/30g range, still acceptable when you pay less electricity to grow.
A lot of what I read says 50/50 hybrids but some will grow nicely others less so, I'm wondering how do I know what's what, like how do you pick suitable strains for 12-12.
