Red LEDs to Grow Lettuce


Apparently red LEDs are 60% more efficient than fluorescent light when growing vegetables hydroponically.

According to IEEE Spectrum Online: Of all the colors of the rainbow, red is lettuce's favorite. Chlorophyll, the electrochemical engine of photosynthesis, runs on red photons. So if you are growing the vegetable indoors in a factory, why waste energy on colors you don't need?

Using a red LED-based growth process developed by Cosmo Plant Co., in Fukuroi, Japan, instead of a fluorescent lighting based one, cuts a factory's electric bill by 60 percent, the company told Agence France Press.

Cosmo's customers uses the technology to produce 7000 heads of lettuce per day all year round in a 10-floor building on just 1000 square meters of space. The lettuce matures more than three times as fast under the LEDs than outdoors. While growing lettuce in an open field is still less costly, growing it inside under LEDs means you don't have to worry about crop-decimating typhoons and other nasty weather.

"lettuce", huh?

this just in:

the price of marijuana dropped 20%

Monthly?????


Hahahahahahahahahahahahaah!!@!!

Not surprising you would see intrest in LEDs as  high electric consumption and heat blooms  are very common clues to clandestine growers
lettece yep , silly pot heads

Are you referring to me? Thats a pretty vague statement.

From what I understand, floursescents are not the light source of choice for indoor growers; they prefer HID lamps. I wonder how the LEDs compare to the HIDs.

Uh, No!

Really? We just picked a few oranges off the tree a few weeks ago. I was playing around with coffee plants but...well.....Even I'm not that patient.

Guess I forgot, this is GD and not the Survival forum.

Those are just Tomatos on my porch Gotta have your Veggies heh.....
