Just a little light hearted discussion about Red and Blue!
Comments (1)"Blue light irradiation promotes growth, increases antioxidants in lettuce seedlings" I looked at the full text from http://hortsci.ashspublications.org/content/45/12/1809.full.pdf+html Under Fig. 3 - "Total photosynthetic photon flux (PPF) was 100 mmolm–2s–1 for all lighting treatments." Equal power rather than photon fluxes should have been used because it typically takes more electric power to produce 100 mmolm–2s–1 of blue light than 100 mmolm–2s–1 of red light. Since the energy of a photon is inversely proportional to wavelength, their blue light had 660/470 = 1.40 times the power of their red light. Now, if you look at Table 1, after 45 days, the blue resulted in 2026/1706 = 1.19 times more dry weight than red. Assuming that their red and blue bulbs have equal electrical efficiencies, they used 40% more electric power with their blue bulbs than their red bulbs to achieve 19% more dry weight. That's what I call "very misleading." Incidentally, a glance at the Figure 3., shows that there were no outstanding differences at 45 days. You would expect a similar variation in growth from growing all of the seedlings under one light source. "In conclusion, our results indicate that raising seedlings treated with blue light promoted the growth of lettuce plants after transplanting. This is likely because of high shoot and root biomasses, a high content of photosynthetic pigments, and high antioxidant activities in the lettuce seedlings before transplanting." No, it is because plants grown without blue light are more susceptible to the deleterious effects of ultraviolet light in sunlight. Protection from ultraviolet is likely caused by high carotenoid content....See MoreRemember the discussion about pillows?
Comments (9)I love my latex pillows, all of them have the holes in them that allows them to breathe and air to circulate. They are heavy but so wonderful to sleep on. Memory foam is horrible it is extremely hot and I feel like I will be sucked into it. I had to wrap a towel around my head or the pillow when I bought one of those kind to try. I plan on always having a good latex pillow. But I have found you don't have to spend big bucks to get a good quality latex pillow. I just had my mattress guy order a latex topper for my new King mattress. The mattress has those divets on the top that look like if it had buttons that pull down tufted and I want to lessen the up and down of those on the surface and give me a little more plush feel. My joints hurt so much I need a little plushness. He offered me a great price for a king size so I am going to go for it. Glad to hear of another happy latex lover....See MoreI had a previous discussion about kitchen paint. Can’t seem to find.

Comments (15)Don't know what thread you were reading. But you said you wanted the crust to be less thick and puffy than you are getting. Sounds like you don't want the thick armor of crust that I associate with some "fish and chips" shops. And sounds like the commercial product that was right-texture-but-too-salty was a dry mix in which you dip the moistened shrimp. So you might try making a thin batter of just water or milk plus egg, moistening the shrimp in that, then rolling lightly in your own not-too-salty dry mix of flour, salt, pepper, garlic powder, plus bread or panko crumbs, and deep-frying. I don't think it is necessary to get all mad scientist with baking soda, vodka, nanoparticles and dark matter just to deep fry shrimp - no-one's grandma ever did that!...See Moresushipup1
