Help ID these Trichocereus!

Hi everyone!
I'm back after a fair while
Now i've been after some T. Terschekii/Pascana/Atacamensis for a while because I like the idea of a Saguaro look alike that will grow a lot faster and be able to cope with the climate here on the Gold Coast
I've bought a couple that I thought could be any of the Trichos I stated, but would like others opinions because I'm not sure exactly what they are
Here is a very young one I bought a few months ago, it has pushed out another set of aereoles since the pic was taken and is maybe 30% bigger


Here is the second one I bought that is a bit older but doesn't look in the best of shape because it was sat in a dark corner for months


These are both now out in the open and recieve full sun mid afternoon and any rain we get. They are next to my Flowering Mam and Opuntia which both seem very happy
Thanks

Hi 19jacobob93

I think you might have some trichocereus pasacana/atacamensis, they are just seedlings and the spination is variable

Hope this could help

Okay thanks! I hope you are right and hopefully I chose wisely

You may wish to compare your plants to those in this pic which are of similar age.

I grew them from seed labelled T.Pasacana.  To my eye they look similar to the plant in your first pic. The plant in your second pic has noticebly curved spines so I'm thinking it may be something else.

Thanks, those look amazing!
Maybe the other one is a Terscheckii, very similar to a Pasacana but with curved spines

the curved spines could be an influence from the tacaquirensis complex maybe they weren't pure breds from like species.Anway love those plants they look great.
