i just recently bought a few tiny succulents from a "rescue" sale at my school's greenhouse... one is Haworthia minima, one is some variety of echeveria as far as i can tell (very short, chunky sage green leaves with a faint blush on them), and one was called "lavendar scallops" but beyond that i can't identify it (scalloped leaves with white and pink on the edges, pale green in the centers & stalk). i put all three under a light with my flytraps, since i was told they all like strong light (the VFTs are right out of tissue culture so they're still on a 15-hr photoperiod). while the "lavendar scallops" is doing beautifully, the Haworthia is looking a bit brown at the base of some of its leaves and the echeveria-thing has some wrinkly looking leaves at its base. now i got these plants two weeks ago and watered them once, a little bit. are they lacking water or getting too much? what exactly do these guys want?
