Wow, thanks so much all!
@ZenMan - I SO appreciate the detailed explanation of how you're doing this. Makes all the difference and really is a true help. Yes, I'm in CO! I've got the heat pads and dome covers both on :)
@shadegardener - great idea!
@Lily_Lover - I like the transplant idea. That's really creative. I'll keep an eye on the soil tops. Thanks for the advice!
Really grateful for all the help so far! Really means a lot, everyone!
