LED and BUD QUALITY

[Ca++]

Lots of LED powered farms use solar arrays to generate power. It's just a slightly longer trip round the houses, to pass 120v on the way.

The guy that invented LED as we know it today, jumped ship to laser 5 years ago. He knows LED is a passing phase. A 1w Laser diode is smaller than a 1w LED, and actually gives out 1w. This is something that scales up, while LED just gets less efficient with more power. A laser grow trial exists, where the laser is outside the grow, and piped in with fiber-optics. Ultimately we might see a very even ppfd as the light moves across like a crazy roboscan. Much as the acres seen above are scanned. It's not just an interesting fim method

No one can tell what is good from a pic. How something smokes is way more important than how a plant looks.

Who is he? Can you provide a bit more info?

There was a start-up called Oaesis using lasers with fibre optics for grow lighting. Looks like they’re out of business.

Edit -
This company is using lasers:

He is Dr Shuji Nakamura, but his work revolves around lighting in general. My post was elements of a few things I have read. Your search engine is your best bet, for finding the latest info

It's still a bit rough round the edges, but people are making progress in the field dubbed laser agriculture

Exx Terrr Meee Nate!

That's not true, there will always be some energy loss when converting electronic excitation energy into photonic one. At least, for commercial hardware. And you cannot grow with lasers, since these exert an overhelming energy/heat input at the same locale site which then quickly cause damage and destruction.

Also it's an apple to orange comparison when comparing the radiant flux energy of a laser with the energy consumption of a light diode...

This looks like a dupery/ scam/ fraud

You misunderstand. It's a matter of energy density, rather than efficiency. A 1watt laser diode, is 1w output, and tiny. This is how you can use fibers to transmit enough light to make it worth doing. Which people are doing, so the idea it doesn't work, is just not right. Our use is more likely to be like a roboscan, which is again, where energy density matters. You can't be spinning around an LED panel, like the optics in a laser projector.

Agreed.

Oaesis appeared to be a legitimate company with a working laser product. Perhaps it was not economic.
There were a couple of published papers by a Chinese team last year also.

I was refering to your statements of comparing normal LED technology vs laser-diodes in the context of growlight and energy efficiency. Wanting to make it sound as if laser diodes are promising for the future. Well, they are not. LED pump technology is still in further development and will get more efficient in the near future.

Have you read any of these? The very idea sounds horrible just in theory. Photons brought in similar phase will travel the exact same path and thus hit the very same molecular structures. This will quickly cause an over-excitation relaxing itself by causing dangerous reactive oxygen species. If anything plants want is to have light dispersed as homogenous as possible, and on any dimension we're looking at.

No, only the abstracts. It seems the research in this area is embryonic. There are few studies and they are recent. If there is promise I would expect to see further research in future. Based only on these and the failed Oaesis company I would hesitate to offer any conclusions one way or another regarding laser lighting. I think it would be premature to dismiss it entirely.

I will say it yet again, I'm not talking about power efficiency. If you insist on putting words in my mouth though, today's lasers can be 80% power efficient. LED is not. Both will evolve, but I will leave telling the future to you. I know we can direct laser light with great accuracy. Car manufactures have gone from HID to LED, and now to laser. Which doubles the distance drivers can see. The guy that created our LEDs got a Nobel Prize, and thinks laser will be better.

Who are you again. You don't think I know?

 

[JKD]

It does look promising.
While research into horticultural applications is currently minimal, there is a lot looking at converting blue laser to white light.
BMW claim 30% less energy input for their laserlight headlight vs LED, though a full headlight replacement unit is ~270% higher than the LED at ~$5000…

$5000!!
Excuse me while I run around in circles flailing my arms about for a moment.

No wonder the owners refuse to dip them.
I wonder what your insurance is like, and just how long until your car is uneconomical to repair. Because you have a headlamp out..

Edit: I think we should get back to talking about LEDs again

my headlight is broken! It's totaled!

Interesting about the effect of fulvic acid. I have read the paper that shows humates depressed THC content. However that researcher applied humates every watering.

Is there paper showing a correlation between terpenes and fulvic?

Wondering how these Cherry Bomb buds will shape up.

This plant smells great not bubblegum scented more toffee, lavender

Maybe its that sour pheno if it smells sour. Lavander flower can be description of it.
Like in RiriSD that sour lavanderish tones.
