if you put a tiny bit of pollen on just a little bud on a female plant will the whole plant have seeds or just the part you pollenate??

That depends on a lot of factors, including amount of pollen, amount of wind and bud placement. If i was to do this i would pick a small amount of pollen and put it on a branch bud, nowhere near the cola. And turn all fans off for a while, maybe even the day if you can.

turn off all fans and mix a dip a q tip in a lil veg oil then dip it into some pollin then pollinate were u want. the veg oil keeps the pollin on the q tip

so in theory, if conditions were dead on if i just pollinate just one hair and one hair only what would happen??
