Hey DV, They all look pretty darn happy! Obviously you live somewhere warmer, pretty much frozen solid here now! We are limited in Canada to 4 plants, so not much choice other than to grow them big if you want some production.
Are you 1 week in from flip or first pistils?
I didn't think 10 days was bad at all. I'm usually around 20 days in my aquacloner. Those are very nice flowers on Karolyn.
