Old Reviews Plant "Stress Detection Glasses" Is this voo-doo or doo-doo?

[Moe]

Came across this (link below) that says you wear these glassse and you can tell whats going on with the plant....

Anyone hear of something like this before? Sounds like its just a filter and can be had elsewhere for cheap.

PRODUCT NAME: Stress Detection Glasses.PRODUCT DESCRIPTION: Sunglass like eyewear that filter out thegreen color from the chlorophyll in plant life which gives themtheir green appearance. By removing the green, one can tell ifthe plant is stressed or otherwise healthy. Healthy plants,trees and turf will appear to be black or gray. Stressed plants,trees or turf will appear yellowish brown or pink. TARGET SITES: Trees, plants and turf that you want to inspectto help identify stress that could be from drought,fungus or parasitic pests like grubs. Since a lowPH can directly lead to turf being more vulnerableto these factors, maintaining it is very important.WHERE TO USE IT: Outside on a sunny day during the time of yearwhen the target plant has green growth.

Anyone? Anyone? Bueller?

I like the idea!!! of course... an exerienced grower can see it and feel it..

 

[mr.mcgregor]

do you think these was created in a lab, or did some random joe put on some colored sunglasses from the £1 shop while inspecting his planst and gave birh to the idea?

I got a big tin of roses & quality streets. im going to unwarp them and look through the colord wrappers to see if I can see anything.

I remmeer when I was young looking at everything with R/B 3d glasses, im sure it had rthe same sort of effect. im

True, but for those with less experience I was wondering i this could be a help or even just an earlier way to confirm something. I'm starting to think growing this plant is like sex, ie there is nothing like experience itself.

I always tend to be skeptical of these type things and see them as someone just trying to make a quick buck. I know from growing under LEDs that it's easy to miss something going on due to the coloration of the lights. I periodically take them out and into natural light to see what's going on. A good growers wouldn't need anything like that.

I tried the quality street wrappers, didnt really work (blue, yellow, brown & purple & green). however using the purple one looking at the girls under the hps hides the yellow light and they look like htere under mh

having said that, looking at the photos on the pc you can see the cal /mag deficency clearly with the purple sweet wrapper over the lens. (although I can see it with the purple sweet wrapper asewll)

I think Muddy is right here - Sunlight is composite of all wavelengths of light and will be the best option for illuminating the plant tissues for most people to conduct a qualitative diagnosis. Laser pointers that are commercially available for their use in astronomy can be used to detect various nutrient deficiencies and heavy metals in plant tissues - this is the basis for laser-induced fluorescence imaging. Confocal diodes that emitt Rayleigh scatterings in the range; 635nm (red-orange), 650nm (red), 532nm (green) and ~593.5nm (yellow), ~473nm (violet) can give chromatic-photo responses from various chromophoric (light-sensitive) leaf consitiuents. However the visual interpretation of plant-tissue content is not yet clearly defined in the botanical sciences since the trans-location of nutrients in plants is a complex observation. If any technological advances are to emerge for the detection of plant tissue deficiencies for use by the home-grower, i'd say it is likely to include novel, tissue-analysis techniques. It will be a while however before these devices become available as effective hand-held instruments. Perhaps in generations to come, our great grandchilderen will depend on these as instruments in the future agricultural industry, for the quality control of crop production in toxic soils.
