Yes, but which molds? I'm discovering that where I live, I get hot temp, high humidity mold issues, not cold, foggy mold issues, and the plants bred for cool, foggy falls, often don't do well in Oklahoma summers.Best strain I've found for Mold resistance is AMS (anti mold strain) from Greenhouse Seeds..
