I was not crazy last week when I said that it felt like Norway Spruce grew "over winter". It indeed is growing fast. It appears that this past winter was not cold enough to put it into too much hibernation. As soon as temperatures climbed above freezing and in fact climbed into mid 60s and even went into lower 70s one week it started growing.

I see growth on all eight trees ranging from 0.5" to 2". Here are the actual temperatures for February and March 2016:
There were two warm spells by the end of February where the temperature stayed above freezing day and night. Then starting second week of March there were some incredibly warm days where temperature was in lower seventies and night temperatures were in the fifties. That, I believe, led to Norway spruce waking up and starting to grow.
Today I opened all sequoias for direct sun exposure. This Spring has come fast and there are no signs of abating.
Most of the sequoia trees have significant purpling. Some that were under foam cones are completely green. Next week I will do a complete snapshot of the 2016 growing season starting point with measurements.
