    All Trichocereus are now included in the genus Echinopsis.

    this is what i know by now (thanx to thenook.org):

    t. brisgesii
    t. pachanoi
    t. peruvianus
    t. ?
    t. pachanoi (typical ecuador/peru var.)
    t. pachanoi
    t. peruvianus

    what you are thinking of as "Trichocereus bridgesii" IS ACTUALLY Echinopsis Lageniformis

    The name "echinopsis bridgesii" was already taken by another, non-psychadellic cactus.

    The people at thenook.org will confirm this for you.

    ALSO, the first one looks far more like E. cuzcoensis than lageniformis. But with all the hybrids and mutations you'll NEVER know the truth. I can guarantee however it's NOT E lageniformis (t. bridgesii)
    number 4 is some sort of e. peruvianus/macrogonus species, with highly etoliated offsets.

    Interesting that they are all hallucinogenic species. Its a shame they are being so poorly grown.

    One should consult Anderson's "The Cactus Family" for the current correct names in Echinopsis and synonymy.

    I have a lot of non-hallucinogenic cacti too ;), it started with these though :p
    can you tell me what I'm doing wrong?
    very new at this, I give them as much light as I can and not too much water, what should i do differently?

    more light. make it possible :) 1000W in a mylar room should do it. with regular feedings, and pest control
    you WILL have pests.

    its correct if you also ensure the temperature does not exceed 15C or go below 0 for more than a few hours at a time.
    and you dont water or feed them. 5-10c is ideal for dormancy. as close to 5 as possible Id say.

    save yourself the effort of maintaining the light all winter.

    Nice looking cactuses. I read somewhere the only way to tell for absolutely certain is to examine the blossoms --- but yeah, it looks like San Pedro (spaniards 'St Peter', so called because he's supposed to be the keeper of the keys to the gates of heaven).

    I've got a witches garden of alkaloid-producing plants just for the curiosity factor, not because I'm actually into ingesting alkaloids (god forbid) --- and there's laws (and stuff) against that sort of behaviour, also.

    By the way,

    Forgot to mention --- check the soil pH - they love alkaline soil at pH of 7.5 to 8. If pH is less than that add lime, crushed shells and the like.
