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"
Green is the New Silver (Lining):?Crisis, Hope and Permaculture?
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.?
Someone on Quora posted this image of what colors of light that plants use. ?I don't know what the story is, but it appears that plants may use green as well as blue and red, leaving yellow as the color they don't use.?
Joan, I thought you were suffering from memory loss? It sure doesn't appear to be true. You've just written two wonderful memories!
Daniel, you continue to inspire me. I think I'll go on a peony search.
Several years ago I was scheduled to attend a conference in Ireland during the peak season of my garden's peony blossoms, which were transplants from my grandmother's garden.?
I learned of the Dublin, Ireland, Botanical Garden's Peony display and spent a most wonderful day there. For lunch, I went to a small Irish pub and had potato soup and a pitcher of beer.?
@Joan - the doggies get a bit of chicken for breakfast, and at night a frozen raw ground turkey product that's made in Vancouver (Columbia River Pet Foods)
Man (Daniel), you must really love Rufus to go to all that trouble to feed him! Makes me feel guilty just buying Dot bagged dog food, usually from Rural King (Alpo and others). I'll check the labeling today. Never thought of egg shells. But I know she rummages through my compost pile where I toss my leftovers, including egg shells.
And yes, she stays indoors during this cold snap. (Me, too!)
Oh! I can't believe it ... yes I can, with simply a little bit of imagination! Is there any healthy commercially made dog food that can be trusted? Since I don't do any of the marketing anymore, perhaps I need to become the dog food producer in the family.?
Bertold, what do you feed your?animals??
Thanks to you both!?
Daniel - you are so right about Chinese dog food. Our Tilly, no longer with us, all of a sudden was showing kidney problems on her blood test. We have a genius vet, and he said it didn't look to him like old age degeneration (even though she was 13 years old). He asked if we gave them any food made in China. We'd gotten some from Costco. We stopped giving it to them, and her kidney function went back to normal. Costco gave us the money back for the food, but they didn't stop selling it.
