There are a lot of variables here. I grow photoperiod plants outdoors in greenhouses, in Hawaii. I have a veg house and a flower house. This allows me to have a perpetual grow, by way of cloning. In the veg house, I can control when the plants flower by using night interruption lighting. When I'm ready to flower them, they get moved to the flower house. If you're not going for perpetual, you can veg and flower in the same house. I grow THC and CBD varieties, which are either indica-dominant, sativa-dominant, or 50/50 hybrid. Sativa-dominant have a longer growing time, and longer flowering time. A big concern for me is mold and bud rot, because I'm in a warm, high-humidity climate. Currently I'm
investigating mold-resistant strains.
As for dense nugs, i.e. nice fat, sticky buds, that's partly a question of what strain you're growing, but also how you grow it. Generally, if the plants are getting all the nutrients they need, and proper watering, and enough warmth and plenty of sunlight, you'll maximize your chances of growing big, high-resin buds. As others have said, some varieties are known for producing big buds and lots of resin. The first decision point for you is, indica, sativa, or 50/50 hybrid.
Happy growing!
