Yeah, you did it a little early but if you had screwed it up, they'd at least be drooping a bit so I think you're good. Congrats... and figure out whether you're going to be doing an indoor or outdoor... this will be crucial when it comes time for decisions about techniques and shape/height of your plants... additionally, as Roberts mentioned, there will be considerable difference in lighting - if you take them from outdoor where they've been enjoying the sunlight for several weeks/months and stick them under lights, they may become stressed and you'll face another set of issues!
Good luck!
