I've found that super hots tend to take longer to germinate and can be more difficult to grow. Don't know why. That's just my experience.

The seedlings in question are Giant Ghost, something I have not tried before. I have grown Carolina Reapers, Habaneros, 7-Pot, Caribbean Reds and regular Ghost. I am also growing Bubblegum at the current time and that does not seem to have any difficulty. Maybe it is just days like this when it is in the seventies that has me itching to be outside.
