I’ve got a bunch of succulents in my office, with a couple that have colonized another cubicle. They’re pretty easy, mine get watered once a week, occasionally every other week. They’ve mostly come from the local big-box store.
This is my main colony, on a modified Ikea shelf with an LED aquarium light on a timer (the black thing along the edge of the upper shelf is the light hood, keeping glare out of my eyes).
And my windowsill group (yes, there is one deceased in the right-hand window, but the farthest left pot is still hanging on).
