I'm having some doubts about the Lophophora's and the E. Bridgesii-s: A couple of them are turning red... They're not standing in the full sun. Today I've watered (and fed) them for the first time. All of them (accept the Aztekium-s) are slowly using to dryer air. (each week I'm making more holes in the plastic that lays on top of the boxes.
Am I forgetting something or lacking something? Or are they just doing right? The red ones aren't thin or dry. They actually look very strong!
