Yes i do know and they got around 12 -14 hours of dark and temps in the 50's.It was only the ones i started last year,they may just need to grow up a little bit more.
Here's some of my girls blooms,i wish i could get names for my noids.
'Polka dancer'
NOID
Peach's & cream
This is a noid i was given a cutting of and it bloomed while i was rooting it,i couldn't believe it actually bloomed after only about 2-3 weeks of being put into soil.
another NOID that i got from a wonderful lady,she thought it was going to be pink,but you can see it doesn't look very pink.It was lighter than the one above it.
another noid,I don't know how CC's are named,i believe it's by the color of the bloom so i just call them by their colors,I don't think they mind that they are nameless
I only had problems with the ones i propagated last year,that might say something for my propagating skills.Oh well i will wait until next christmas when they are older and more established maybe they will bloom then.
