I am guessing you are talking about using coffee grounds indoors on you succulents & herbs? Unfortunately I have no experience with that, but I have used them as a soil amendment in my veggie garden, incorporated them in my compost pile and used them as a mulch around plants. For all 3 of those uses, coffee grounds are great. They are actually neutral in PH. Sometimes as a mulch they can harden a bit & shed moisture. I just break up the crust.
RE indoor use of coffee grounds, I gave seen them grow mold (I once left coffee grounds in my coffee maker before going on vacation). So indoor use may not be a good idea.
