Strobe Lights and Cannabis

[Forest20]

I was reading ED Rosenthal The Marijuana Growers Handbook and came upon this tidbit was wondering if anyone tried or is using a strobe light in your grow room.

let hear everyone view but bekind its just words.


STROBE LIGHTS
Some botanists have speculated that the pigments which are used in photosynthesis respond to energy peaks in the light wave. These scientists believe that much of the light is wasted by the plant because it isn't "peak". They speculate that much energy could be saved by supplying the plant only with light "peaks". One way to do this is by using a strobe unit in place of conventional lighting. The strobe flashes a high intensity of light, but it is on for only fractions of a second. The result is that the plants receive many light peaks in between periods of darkness. There has been little research on this theory, but one grower claimed to get satisfactory results. One way to use a strobe without too much risk might be to use it to supplement more conventional lighting. If a higher growth rate is noticed, the strobes could be tried alone. Should this system work, electrical costs could be lowered by as much as 75%.

they have very bright very tiny led strobes at autozone, put it on one plant and see if you can tell

 

[Forest20]

thanks Pseudo of the info was wondering if anyone in the community has looked further it this theory

I read about pulse (strobe) LED technology somewhere a few years back. Is there any other type of pulse lighting besides LED and strobe lights? If my hps cycled in fractions of a second it would melt.

I was thinking the highest light peak might be in responds to UVA and UVB in the Enviorement

i read about this years ago, i never persued it though. if you find anything more out be sure to let us know.

Technically, electronics work like a strobe light. We just visually detect it with our eyes because its so fast. Say your light operates 60hertz. Its flashing on and off 60 times a second.

At-least thats how I understand it.

We had read this years ago but never experimented with it either. Always did spark a bit of curiosity though. Any more info would be appreciated, thanks.

What I was read i came upon this information and was thinking it might relate only in flowering and intial veg. Might deal with HPS and CFL.

Light is electromagnetic radiation, particularly radiation of a wavelength that is visible to the human eye (about 400–700 nm), or perhaps 380–750 nm.[1] In physics, the term light sometimes refers to electromagnetic radiation of any wavelength, whether visible or not.

Note, n = 1 in a vacuum and n > 1 in a transparent substance, where n is the index of refraction.

When a beam of light crosses the boundary between a vacuum and another medium, or between two different media, the wavelength of the light changes, but the frequency remains constant. If the beam of light is not orthogonal (or rather normal) to the boundary, the change in wavelength results in a change in the direction of the beam. This change of direction is known as refraction.

The refractive quality of lenses is frequently used to manipulate light in order to change the apparent size of images. Magnifying glasses, spectacles, contact lenses, microscopes and refracting telescopes are all examples of this manipulation.

Light refraction is the main basis of measurement for gloss. Gloss is measured using a glossmeter, and an objects refractive index is what the glossmeter analyses.

Think about solar flairs in the Environment

 

[Forest20]

quick up date think about this a strobe light beginning LST and FIM for example

 

[Scfarmer]

Did anything come from this?

 

[Granger2]

I tried it, but the ladies got nauseated and had seizures. I'm pretty sure an HPS or MH bulb would be fried quickly with a strobe set up. And I pity you ballast. I doubt there would be any energy savings to speak of since it takes more juice to ignite a lamp than to run it. -granger

As Capn said, all lights are already strobe lights.

The two halves of 110 volt current are 180 degrees out of phase with each other with respect to ground.
HID lighting is intense enough to trigger good response so I alternate the hot wires on the row of lights. When one bulbs peaks the next one is at zero so the plant gets a more continuous supply of light.

The T5 section is wired differently as the T5's do not have the intensity for efficiency. By having all the T5 fixtures peak together the plant receives higher light levels for triggering photosynthesis.

The LED clone light used here has a strobe feature available also. For tender young clones the light can be put very very close and the strobe percentage of 'on' times can be set from 5% to 95%. This allows the intensity to be enough for reaction but the total energy is kept too low to dry the clone.

The 'strobe' effect that first came to mind is Disco era stop motion flashing which has a 99.9 percent 'off' time and to make that .1 percent of light work it would have to be a thousand time stronger than the steady state light it is replacing.

Kids like raves. Why not cannabis?

 

[RustyShcklfrd]

Lights are using the full wave when operating at 100 % (undimmed) ,its when they are dimmed using traditional methods that the sine wave is chopped and the light is actually "turning of and on" 60 times a second, and the length of "off time" or the amount of the sine wave chopped out, determines the "brightness" of the lamp. Not all dimmers work this way, but thats another can of beans.
Peace

 

[Forest20]

Whoa...never thought this would get any notice....I still believe we not look at wave length of light, but understanding of thermal footprint needed? just a theory
