Little bit of both. One main cola in a humid tent can mold. Much smaller chance that many colas slightly less in size would have a chance of mold. A Scrog under a net is the same as LST except you aren’t tying them down, they are being held down by the net and you spread the plant out under the net allowing the same as LST and spreading out. And keeping the plant low and spread allows for the small side branches that would never reach the canopy to grow up into the center vacated by the main and stronger/taller side branches. Only difference with the two techniques is in a Scrog, you would usually prune the bottom third out and with LST those lowers get a chance to produce as well.
