Would anything special besides me letting it grow? - Could you rephrase this?

And yes the dried up seeds from the bud you buy will work. You will want to use the darkest ones you can find like the black seeds work the best and wrap them in a wet paper towel then put that in a clear plastic ( Sandwich) Bag and put it on a window sill or anywhere it will get sunlight and Don't check on them more than once a day as the bag will lose its humidity. in about 2-3 days they should germinate and you can plant them. Not so sure about the fertilizer because this is my first grow too and i haven't used any yet and my plants are doing fine. But search around a little i learned everything i know so far from just this site...and Google.
