i agree with you there about mesembs seemingly being every pests favorite dish. I have read where these lithops can make great house plants....so im going to try that out...my room has a south facing window, so lighting wont be a problem, and i have a bit of protection for them with my blinds if it gets too strong for them. I would say the biggest seedling so far is a tiny little 3MM...say something like this --> O

No rush to remove the lid, they should be fine under there for a few weeks. Remove immediately if you get any rotting or fungal problems. I keep them well watered until the first true leaves come through. Provide strong light, ideally direct sun once the lid is removed, but don't let them overheat.

Hello Maria, Just close the bag and leave it be for now, just make sure there is enough moisture. You can replant the seedling when they get strong enough, I suggest to wait at least until first true leaves emerge after first shedding. Happy growing :)

I didn't think about getting information on the forum and did read many of them. Not many gave step by step at this stage and what to do after. Very interesting to hear that reaching to 2 to 3 years lithop stage is not always a success. This is my novice advice on how I did it. 1. When the flowers dried up, I rub them with my finger tips into a lined dish of water. I lifted the liner out with all the seeds (they were so small, I wasn't sure if there were any). I let them dry on the liner and folded it and placed in a zip lined baggie. 2. I used a 4" plastic pot and mixed cactus mix, horticultural sand, pumice into the pot. 3. I placed the pot onto a saucer and spooned water into the soil until completely wet and let it soak up water from the saucer. This was to be sure that it was soaked. 4. I sprinkled the Lithop seeds onto the top of the soil. 5. Next I sprinkled a layer of horticultural sand on top of the soil. I spooned more water onto the seeds. 6. Placed the pot into a gallon size baggie and closed it up with a twist tie. You can also use a zip lock bag. 7. I placed it outside away from direct sun, but where it got filtered sunlight. I didn't look at it until about 7 weeks later and found the new seedlings pictured above. 8. I removed the pot out of the plastic bag and left it out during the daytime under filtered light and drizzled water on it (once daily) to keep soil wet. 9. I return it back to the plastic bag and close it for the night. 10. I plan to repeat #8 & #9 until I see new leaves growing. Based on posts I read, it should begin to have new leaves around 4 months + Since my post, I found an additional 8 new seedlings growing. I did read that some have continued to just use the baggie......as possible new growth can happen. I'll post updates if I'm successful later this year.
