Bud worms are bad here in OKlahoma as well! Another advantage of large plants is losing a limb or a cola here and there is a relatively minor loss. Bud worms are inevitable outdoors. Some strains are way less tasty to them than others. Zerotol handles PM all the way to day of harvest and I try to run strains that will finish in late Sept, or early Oct.. We get a lot of wind here so strong support is mandatory, regardless of plant height. But the better the genetics are adapted for your region the better you will do! Lots of trial and error, you have to get pretty Zen about it, you will loose plants! Just like in any outdoor gardening.
