| Massimo. Welcome!!! Since noone else has replied...i will give you my 2 cents worth... Not an expert... but if they were mine, i would keep them as is until they get to large for the dome. They obviously love the conditions that they are in and i would give them the best growing area for them to become strong. After they get a little larger, then you could lift the lid and keep them warm and semi moist until you feel comfortable seperating them. Then let them dry out just a little. Sounds like they are fine as they are. Maybe some others will chime in and help you... Take care, Laura |
