tightest outdoor grown buds?

does anyone know what strain will grow tight hard buds,preferably a medium
producer or more for outdoors?
my personal limited experience has been fluffy buds to semi firm.
there is so much info on the net that it is hard to find the info i search.alot of seed sellers state if they will grow hard tight buds but they dont say if that is for indoors or outdoors.i do know that indoor grows will provide tight hard buds from various strains all the reading i do here and else where.
im not set up for indoor grows nor do i want to.so if anyone can help me with my next year grows[ideas],i would appritiate it very much.thanx.
