Signs of Spring On the Way. 3.1.19
We remain below freezing day and night through tonight, expect a warming trend to start tomorrow. Nights remain below freezing. Snow flurries forecasted for mid-week; with a warming trend, we expect snow on top of ice on the highways. U.S. and State highways should be worn off by traffic while the county roads will probably present hazards.?
Patricia, Williams Lake, B.C. looks cold for the coming week.?
Ruth, oh! to see spring leaves! They can withstand light frost and snow. Let's hope the spring blossoms dont\'t get damaged.?
Spud, what is happening in?Pocatello, ID?
Daniel, how are you doing with weather this winter?
Bertold, to what dog food brand do you currently use??
Spring bulbs have put up leaves here, but next week will be all-Winter. <sigh> I have a bit of Spring fever too.
Looks like our yard, Joan.
Pretty depressing, Joan! We're expected to get a dusting today.
But, spring is coming. Redbuds and forsythia were blooming from Florida to Tennessee. Another 3 weeks?
My greenhouse, March 2, 2019. It will be a while before I can even get in the door.?

Wikipedia also says that many plants do best with dark periods, the hours needed vary with the specific plant. ?It's complicated and not enough studies have been done.
I read Wikipedia article on "Grow Lights" and it indicates green light is needed besides red and blue, but the closer you can get to sunlight, the better. ?It has a chart similar to the one I posted yesterday. ?Here is some quotes from Wikipedia:
"NASA has tested LED grow lights for their high efficiency in growing food in space for extraterrestrial colonization. Findings showed that plants are affected by light in the red, green and blue parts of the visible light spectrum."
"LED grow lights vary in color depending on the intended use. It is known from the study of photomorphogenesis that green, red, far-red and blue light spectra have an effect on root formation, plant growth, and flowering, but there are not enough scientific studies or field-tested trials using LED grow lights to recommended specific color ratios for optimal plant growth under LED grow lights. It has been shown that many plants will grow normally if given both red and blue light. However, many studies indicate that red and blue light only provides the most cost efficient method of growth, plant growth is still better under light supplemented with green."
"Many studies indicate that even with blue light added to red LEDs, plant growth is still better under white light, or light supplemented with green.[27"

As we gear up for a new season of growing food, the changes in weather and climate leave us with many unknowns, we need to be flexible and adaptive. I chomp at the bit to get my fingers into the soil and am getting ahead of myself. Slow down, Joan, don't get seedlings started too early!?
Thanks for the information on absorption spectra of pigments, Spud, and the?comparison of LED vs T5, Daniel. ?I can start there and assuage my eagerness for a little longer.?
