Those are some nice mature seeds man. They're fatties too. I like big fat watermelon looking seeds. If you got those from a bank then they did you right for sure.
float a couple in a cup of lukewarm water--give it a few hours--if they sink chances are they are ready to go--like the dude says above--get reading --see how far you get--get the gear together you will need--keep reading........good luck
You can't judge seeds simply by looking at them.
I have seen really fat, dark, hard seeds that didn't do shit and I have had the greenish, immature looking seeds turn into monsters.
