first hyacinths out of the dark

I've heard that forced hyacinths need to come out of the dark and cold by December 1st if they are to bloom by Christmas - but some bulbs grow faster than others - certainly a better chance of Christmas blooms the sooner they come out into the light and warmth.

these have been out for a couple days and have started to green up, initially the stems are yellow after being in the dark
