What strain will produce the hardest nugs?

Northern Lights, White Widow, Skunk.

Use an HPS, they'll be as hard as my nuts.

I know what lights to use. Certain strains just grow denser buds, period.

yeah i got an oz of purple kush( and ine the south, that shit was 650!!) ridiculous..... but i got one seed from the bag, it germinated, was a damn male. so i took the pollen and shook it in a bag, saving it to pollonate my mp5k wich is a afghnx AK-47 so at least ill get somethin out of it, hopefully its just as good

Hashberry is definatly pretty dense

this is a stoner threrad... thats for sure..
