theres some indicas that are, sometimes they have really small node separation though(this means DENSE ass buds though, so not bad, just afraid of mold out here). 12/12 from seed works good with some strains, its good to know if they're yielders before doing so. theres just so much variation these days, theres a long flowering indica out there im sure, and a really tall growing indica so i cant really say all are good for it. i believe any plant benefits from lst really, just redirecting the flower of energy from the top bud helps out big time, you can harvest everything on the plant on the same day, without it, you should probably run the bottoms for a week or 2 so the bottoms can catch up.
