Hey there budman, some strains just have more pistills than others some strains have more trichomes (frost) than others, simple as that. Other strains that have a lot of hairs are gorilla glue, I had mine have way more hairs / pistills than other strains I knew... In the end yeah I do like that bag appeal as well... And it doesn't mean the weed isn't absolutely killer right ? Anyway hope this helps ! 🚀
Different strains hace different amount of frost. Light color temperatures produce different amount of frost, more blue light makes frostier buds, more red light, yields more, but with less frost
