Hello NMann, I hope you're enjoying the path of learning how to grow!
What you see there on the stems are called calyxes (the sack) with pistils (the white hairs), which tells us that is is a female plant.
A pistil catches the pollen released by male plants. The pollen will then travel down the pistil into the calyx, where a seed will be produced.
If pollen is never present during the life cycle, the plant will not produce any seeds. Instead, it will produce more calyxes rich of cannabinoids.
That is the product you are looking for, buds full of cannabinoid-rich calyxes without any seeds.
Fun fact: Premium quality weed is sometimes called "sinsemilla", which is spanish for "seedless".
Good luck with your project!
