Hello.

I am wondering if somebody could give me a hand or an idea. I've looked all over the place for an answer but I can't find one.

I have a couple of mini-greenhouses on the go with a bunch of little sprouts that came up in the last two weeks. (Tiger's Jaw and Lithops.). I have them under a grow light for 16 hours a day with the lid on.

I saw in a video that after 5 days you can start lifting the lid 2 x a day for 15 minutes each time.

So that its where I am confused. I know with other plants, I remove the lid once the plant sprouts. What about these guys? Do I remove the lid, or continue to give them air two times a day. I don't want to remove it too early, nor too late.

Any friendly help is welcome, please.

Leave the lid on (without removing it) until the baby plants are about the size of a small (cooked) pea. A few millimeters wide. The actual time you have to wait depends on the species and the rate of growth. The reason you want to leave the lid on is to avoid microorganisms drifting into a moist, rich environment where they can easily multiply and overwhelm the succulents. When you do remove the lid, you are doing it to begin the process of reducing the humidity in the chamber from 100% and getting the plants on a cycle of wet soil and drier soil. Try to make baby steps along the way, so that when you do remove the lid, you mist the surface with water fairly often (at first) and don't allow it to dry out too much right away. The idea is that eventually (at months of age) the plants will prefer the soil to go nearly or completely dry in between watering, and you want to help them get there without too much stress along the way.

So you know, Lithops are not the easiest plants to keep going long term. The Tiger's Jaw should be much easier.

Perfect! Thank you!

That's interesting about the Lithops and Tiger's Jaw, from what I've read I would think it would be the opposite! I'm sure I'll be rounding the learning curve for a long time.

If at some point down the road you want to share pictures here and get more advice, I'm sure people would be curious to see how your baby plants develop.
