rosalux 660nm bulb?

[guineapig]

has anyone heard of this contraption or is it another phantom product like the Vari-ballast and the Wicked Roots super-vaporizer....

The ROSALUX is a new and revolutionary lighting product being introduced by HOTBOX INTERNATIONAL for the serious grower.

Light between 650 – 680 nanometers in the red region of the spectrum coincides with the maximum absorption of chlorophyll in plants and the greatest photosynthetic efficiency.

Trials dating back 20 years have shown that red light in this band is beneficial to many plants but no comprehensive work has been done to establish the exact benefit to each particular genus or variety or to record the most sensitive stage of growth.

HOTBOX are primarily encouraging sales to professional growers who wish to experiment and monitor the beneficial plant growth on their particular crops and the cost effectiveness of the treatment.

The ROSALUX can be supplied at 110 volt or 230 volts. Running costs are less than 1 cent/hr.

HOTBOX are offering special low trial prices and generous discounts. Enquiries from potential distributors are sought worldwide.

Hmmm, brings a whole new meaning to red light district!

yes....really the only wavelengths of light a plant needs are 420nm (blue light) and 660nm (red light)......so if you could attune a bulb to these specific wavelenghts i don't see why you wouldn't have good results......it would be a good experiment anyway....

as well as red light receptors (phytochrome) and blue light receptors (cryptochrome), scientists theorize that plants have specific receptors for UV light that have yet to be discovered.....

Interesting information GP. Nice work. Got any information on prices of their units?

Plants will respond to narrow range light like you mention above but to say thats all that a plant needs is a bit much. Plants can and do use a much broader spectrum. And will also adjust themselves to the qualities of the ambient light. Phytochromes mediate responses to red and far-red light as well as showing partial activity extended through the green, blue and near-UV wavebands, not just at 660nm. Cryptochromes respond to blue through to uv-a , not just at 420nm. Phototropins react from the bluegreen interface {500nm} through to uv-c. And there are still receptors undiscovered.

The grow room of the future might look like a lazer light show.

Seems to be contrary to the nature of PAR which contends use of the whole spectrum from 400-700nm.
