Newbie. Flowering advice please!!!!

Have 4 plants in the SE area of the US. they are about 24 inches tall in preflower. If placed outdoors under full sun til harvest will the buds be dense by the end of the season???????? any reccomendations??? STRAIN is Crystal from nirvana. Thank you everyone

Its getting a little bit late. I assume these plants are still in the veg stage? What's the flowering time on that strain? If its a quick flowering indica, you can probably pull it off, depending on the first frost in your area. What's the weather like in your area in late October/early November?
