running super dense strains outdoor..............?

it seems like the denser the bud the more prone to problems, do you guys feel the same way and what do you do for these plants? i got some gsc that is really dense but iam worried about mold outdoors

Mold shouldn't be too much of a problem unless you live in a moist environment that gets foggy and misty n all that stuff but if you are worried about mold and want to prevent it from happening just trim the water leaves where needed so that airflow can get to the buds more. more airflow less chances of mold.

some strains are bred for mold resistant and are dense.

Depends on your humidity and rainfall too, if its between 50-70% consistently and you only get 600-1000mm of rain a year I wouldn't worry too much about 'super dense strains'.
In my opinion the big fluffy buds tend to get rot easier than small dense nugs.

You need to grow in area where you get sun first thing so they're not sitting in moisture till 12pm.
