Ok, since i live in an apartment, I have no choice but to grow my lithops under grow lights. Can't seem to find any info on the net with regards to growing lithops under growlights. Anyway, here goes... I place a 38watts PL Philips light over the plants. The lighting is about 3-4 inches from the plants. Hope the light is sufficient. I am giving them 16 hours of light at the moment.
Been searching the net on their growing media too and found a few source saying that we can use cactus mix with more sand and course sand added. So that's what I did. Then I top up with stones etc.
I also have transplanted them into a community pot. Hope I am doing everything right. Just grouping around in the dark so to speak... and hope for the best.
I have turned of the PL lights for the picture. So it's look kinda dim.
