Hello.Hello @Lerugged ! What is the potency of these landrace strains? Can you flower these early indoors to keep them from getting too tall?
I would say the potency is around 18 to 20 %. The High is completely different from hybrids and modern strains. It's all high and no stone. No ceiling either.
You could grow them on 12/12 to keep them smaller. Otherwise you could quadline it like @StoneOtter did, which kept it quite low.
Hope that helps
