>> but I have to dump trays of ice cubes on them in winter to make them bloom well.
Wow, I thought I was crazy! But it's a real thing!
Well, I probably AM crazy, but not because of that.
I red someone who did alternating warm/cold +moist stratification using periodic additions of ice cubes.
Anyway, I think i should quit and go home while I'm ahead. Thanks, zuzu!
