Thanks!
I started just a few seeds two days ago - don't covered. They germinated after less then 48 houres! I saw the small sprouts today in the early morning. Amazing
I guess, TPS's need light to germinate. Will start new seeds today.
Gunnar - I cover the pots with a transparent foil to keep moist, and lift them up every day for air circulation. They can't dry out.
