Can you ID these cacti? I know that they are some kind of Trichocereus/Echinopsis. They are +2 years old from seed and grown under sunlight with organic fertilizers.(neem, horse poop, alfalfa, egg shells, ewc, bat guano)

Best guesses:

Pic 1 = No real idea, and from that angle not even sure they are Trichocereus.

At least two appear to be Bridgesii (Cup #s 6 and 3).

The rest appear to be mostly Bridgesii (Lageniformis) or possibly Bridgesii X Peruvianus, and a few being possibly Peruvianus (Cup #55 and all in pic 5).

These are just guesses. I'm no expert and they are difficult to ID when young. Regardless, you have a nice collection which will reward you richly in the years to come.

Picture #1 almost looks like trichocereus grandiflorus...

Thanks for info. I think that the first ones might be terscheckii. How long do you think it will take untill I can use my cacti for mescaline extraction? You can find pics of rest of my cacti in my introduction essay.
