well as a first timer you came to the right place! just remember theres only so much you can get out of random genetics the first time. even 2 or 3 grows from now youll realize that you stressed about things you now know arent worth a second of thought and have all new thoughts to stress out about.
the main thing is to get one set of genetics and run with it for a while. until you get it dialed in perfectly. by then youll be able to do that with anything thrown your way.
as for seed sites i personally have used
THE SINGLE SEED CENTRE with great results everytime.
especially if you only like growing a plant or 2 outdoors. get a respectable strain thats tried and true for years and start there.
they have a "no bullshit shipping" option which i highly recommend. and its only 3-5 dollars more than standard shipping so its for sure worth it.
also they have great customer service. once i got impatient with how long it was taking and told them they needed to refund me or resend my order.
what a surprise when i got both packages.
and another time i accidently chose to sign for the package WHICH NO ONE SHOULD EVER DO!!!
and i wasnt awake when my mailman came by so i told them and they resent the package free of charge minus the $15 for shipping which was well worth it.
everyones like you at some point all the way to the admins on here.
but congrats on your first harvest! well soon to be harvest.
Feel free to pm me or post on any of my journals asking as many questions as possible.
I hate seeing noobs get shot down for asking common questions.
also i mean no disrespect by the word noob strictly a new to growing reference.
