I grow Pure Power Plant which is a South African sat that behaves like an indi.
A trick to control stretch is keep them under the HALIDE the first 2-3 weeks of flower on 12/12, and THEN after stretch swap out for your HPS. Also, keep the difference between night and day less than 15, preferably less than 10' F.

That being said, PPP doesn't give me troubles.

For a lot of other sats... haha better you than me! (I don't have space or patience)
