Reddit reviews Succulent Container Gardens: Design Eye-Catching Displays with 350 Easy-Care Plants [Hardcover]

Good effort. I like the idea but here's some things you'll run into as far as issues I think.

So, for starters, you have Euphorbia...something like trigona but I think it's a different species. Then maybe a graptoveria behind and to the right (with a sedum next to it?), then an Aloe aristata - the green spiky one in the front middle, then opuntia microdasys in the back right corner, and then I think Mammillaria elongata in the front right.

The Aloe needs less light than the rest (although I'd still shoot for 4-5000 lux, which for me is a couple of 2 ft T5HO lamps about 6-8" away).

The cactus will not want much watering.

The graptoveria may want a ton of watering compared to the rest (at least my echeverias and graptoverias seem to soak up the water). Similar but a bit less for the sedum.

The bottom needs drainage (preferably holes not just a layer of gravel) or water will pool and make a bog - maybe it has drainage and I don't see it.

If I was redoing it, I would pot up the two middle back together, the aloe by itself, and the two cacti together and maybe the euphorbia with them - I've had issues rotting out Euphorbias too if I water them as often as some of my succulents.

I've had some limited success with keeping different kinds of sedums together, or different kinds of echeverias, or say a graptoveria fred ives with an echeveria nodulosa and then a carpeting sedum like sarmentosum as the 'ground cover.' This is just a sample, and I am by no means an expert at arranging.
