Happy Carrots?

Happy Carrot Tub #1

As most of you know, I planted carrots a few months ago. They are the cool "kaleidoscope" kind, with different colors and all. They seem to be growing great!

Happy Carrot Tub #2

Problem is, I don't really know when to pick carrots. Or rather, dig them up. I couldn't stand it the other day (go figure, lol) and started pulling.

Here's some of what I found:

You see these carrots? They are really... small. Now the tubs they are in are super deep, so it's not a matter of not having depth. And I water them a lot, put the occasional fertilizer. And yes, some have been moved because when I thinned them, I put the others in other tubs. And those seem to be growing, too.

And if you look here - the greens on the carrots are big and bushy and green!

The carrots though... really small. 

Yes, I know, I need to get on the internet and look all this up and see what I'm doing right and wrong. But in the meantime, I can't decide if these carrots are happy or sad. And the rest - still in the tubs for now. *sigh*
