I have 5/6 of the plants you mentioned but before I get to your question, just a disclaimer, probably 90% of the other people on here probably know more than me so if there’s conflicting info, don’t trust mine! For me and in my climate, I water my Haworthia around once a month since it’s in a glazed pot and keep it in relative shade. My P. afra on the other hand, get water between 5-10 days depending on conditions and get as much sun as I can possibly give them. I’m not sure those two together would get along overly well

Dont make mini gardens, the plants will not prosper. Youll find the rhipsalis and the faucaria problematic to grow together, because one is a moderate drinker, the other likes to stay heavily on the dry side. Haworthia likes moderate light, but little water,the kalanchoe you mentioned likes to roast in the sun. Same could be said for other plants, most dont work together. The only ones ive actually seen do that, are dracaenas... and most arent succulent.

Grow lights will not provide sufficient light, and are only used for overwintering in the northern regions(and ive read arguments about those). Since this is at work, maybe wasting power could have repercussions, so i wouldnt try.....

Your tray isnt even deep enough btw.....

Thank you for the help thus far everyone. Just to answer a couple questions:

- the tray is an example. I will be getting a slightly larger, deeper one ( app. 8 inches square and about 4 inches deep) but wanted to give an example of the general type.

- re: grow lights, I don't have any windows in my department but I do live in the tropics. If the grow light is not enough, I'll place the plants out in the morning sun daily (app. 3 hours) and leave the grow light on at nights. Power, luckily is not a concern.

Can I be given some examples of a few plants that may work together please? I have very little space on my desk (less than a foot), so I'd ideally like to plant them together. Thanks again :)

Nope, thats the point, different plants, have different root needs, different watering needs, light needs, growth speeds, etc. Even if you planted, lets say, a zebra haworthia, and another haworthia, its not going to work out. If you plant 2 very close species of cacti, its not going to work out.

If you think on moving your plants on a daily basis, forget it, its a really bad idea. it will stress them.

Might i suggest growing medium light plants like tradescanthia or sanseveria or pepromia? they have much lower light requirements than your plants, and provided you plant them deeply, and have some kind of separation barrier between them you might just pull it off.

Personally, I wouldn't aim for 5 or 6 succulents in one planter for an indoor work station. I think that's too many. Personally, I like to keep succulents individual -- easier to work with light requirements, watering requirements etc. Three hours outside in morning sun is BRIGHT sun. Then moving plants indoors to a desk is a start change. I think milevskistefan above is correct -- perhaps a peperomia or Sansevieria would be easier to care for in an office setting.
