I found this cactus for sale, and was wondering if anyone could identify it for me. I think it could be a bridgesii.

yep Trichocereus bridgesii its good stuff!

Let's hope I can purchase it then.

That one looks like a peruvianus or maybe even cuzcoensis to me. It's a little hard to tell without a sense of scale, but it looks too fat to be a pure bridge. How are you so sure its a bridgesii, DreemMaster?

So it's more than likely a magic species then. I'll try my best to purchase it. It's a good size (79cm long), and I'm crap at sprouting seeds. :S
