Yup - you are right - high humidity. You keep them covered - and they send the roots all over, you keep them open - the roots stay in soil.

Thanks Irina. I will gradually give them some air.

I think you can keep them in the open now - after you gradually give them air of course. i looked at this variety - oh my - savoy cabbage ;-)). And variable - flowers can be green - white, green white blush, green white pink, green white pink raspberry splashes. Not even two plants bloom the same... all different...

I agree, humidity.

Yep, humidity! Yum,,,,savoy cabbage! Rosie
