I planted these around mid-november. From cacti/succulent mixed seeds from amazon. I also got a covered tray from amazon.
I water them by spraying/misting them until soil is damp. Only after a week or so when I notice the soil is dry and there isn't condensation on the tray cover.
They are on a heating pad set to 75 degrees. And I am using grow lights on a timer, 12hrs on 12 off.
