Ferocactus ID?

[truffula]

I grew these from seed, out of one of those cactus kits from the craft store. I think the big one is a Ferocactus, but I can't tell which species. I'm not sure about the two small ones either,, they might be golden barrel cacti, but I don't know if they are still to small to ID. Any help would be appreciated. Thanks!

The small ones are golden barrels, i'm sure about that. The big one, definitely a ferocactus. But one can't be too sure at this age. Could be stainesii, could be emoryi, could even be gracilis...
You just have to wait a couple of years to be sure.

Thank you so much!

Nice little cacti. Also be sure that the jar that you're using has drain holes.

Ferocactus latispinus "devils tongue barrel"

Ferocactus latispinus "devils tongue barrel"

I'm quite sure it's not this! The spination is very different, even allowing for it being very young. F. latispinus has very wide flattened central spines, there is no sign of these.

F. emoryi could be an option. As Elie says, there are other possibles at this age, it's hard to tell.

I'll go for F. emoryi too.

Upon looking again I think you're right it'd definitely not

My first thought was Ferocactus stainesii. But indeed, hard to tell.
