I bought a 24 inch aqarium light that the output closely macthes the absorption peak of blue chrorphyll used in photosynthesis. Is this good If I have one normal full spectrum florecent light bulb with the aqarium light bulb?????? flp420
i dont know thats what it said on the box. I read somewhere that lights that give of the blue light of the spectrum is good for the plants. ( seedlings) have u heard of it. flp420
420. Plants appear green because they reflect green light, while absorbing the other colours of the spectrum. The green pigment in plants is chrorophyll, essential for photosynthesis. The green portion of the light spectrum is relatively unimportant to photosynthesis, since it is mostly reflected by the plant. Chlorophyll absorbs light energy from the blue and red portions of the spectrum, to convert carbon dioxide and water into sugars to be used by the plant. Without red and blue light rays, the plant will weaken or die prematurely. The orange-red portion of the light spectrum is very important to plant reproduction. Pigments called “photochromes” absorb the red and far red portions of the light spectrum. Photochromes regulate seed germination, root development, tuber and bulb formation, dormancy, flowering and fruit production. Therefore, the red portion of the light spectrum is essential to plant growth, particularly during the flowering, fruiting, and reproductive stage. Plants need light from the blue end of the spectrum, as well. Blue light stimulates chlorophyll production more than any other colour, promoting thick leaves, stocky stems and strong vegetative growth. Carotenoids, the yellow-orange pigment in plants, absorb blue light and control leaf fall and fruit ripening. Riboflavin, containing another pigment, absorbs violet light and influences “phototropism,” the movement of plant foliage in response to a light source. “Positive tropism” is the movement of plant foliage toward a light source, while “negative tropism” is the movement of plant foliage away from a light source. Positive tropism is greatest in the blue end of the spectrum at about 450 nanometers. At this level, plants lean towards the light, spreading their leaves out horizontally to absorb the most light possible. Lack of blue light will make plants tall and spindly, since the plants will stretch out in search of blue rays. Adequate blue light helps ensure each plant’s natural shape and prevents “legginess,” or unnatural elongation of the stems. Hope it helps. Give it a go but you'll need to suppliment the lighting to get the whole range. All grows should have supplimentary blue to give a stronger, denser and overall healthier plant. If it works, share the knowledge. GA.
thanks for the info!!!! Thats alot, u must know ur stuff. LOL Anyways I am gonna try the aqurium blue light bulb and see what it does> If It does good I will let u know. Thanks flp420
hey I tryed the light bulb> the thing is, is that It looks like a black light Its not as strong but the bulb when its on is blue. So I am gonna try it still but if anyone says anything else please let me know thanks flp420
Guys just experiment and see how things go. Your thinking outside the box and may come up with something. Just let everyone know what happens?
