Which strain to start with?

if you sog, can do many of them.. use books, blocks of wood or anything else to even their differing heights out... mainline is cool, but likely is slower initially. scrog helps support floppy plants, but if they are thick stems, usually not needed. Still in thos contexts it helps organize and keep things spaced out for airflow etc.. still many benefits from it. these are all personal preferences. I'd want to grow them long enough to take some clones... then of the buds i like best, keep those and kill others.. rinse and repeat throughout time :P the donor list changes over time, slowly for me :)
