A lot of the bs products at the grow store will increase defensive trichs (cat tongue texture of stems) and will also elongate (mutate) the resin stalks which the heads are suppossed to grow on.
Nothing in the grow store will add trichomes, but the big twisted stalks (mostly with no heads on them) can make a bud look like that, and it sells.
Back home, the resin heads didn't have long necks under them. The shorter the 'neck' the better the smoke, almost always. You wanted resin glands hugging the calyx. Not suspended from deformed stalks that make your bud look frosty. With all the chemical weed, its all long twisty white stalks, less heads than stalks!
You can smell PM. Youll probably smell milk h202 and neem first though.
