New Led Or Not ?

I'm going to ask this is a couple areas: What is best nm mix for cloning? Or asked another way- to develop roots?

If you look at that ledgtow.eu page, he just did a root test.. FarRed promoted more roots.

They did not start out as a brown lens, they were used and the UV has degraded them.....to turn them that color. It happens all the time, i have UV diodes in mine that look exactly like it and they started out clear, they produce a blue around 410nm which its bandwidth +- 20nm dips into VIOLET And Ultra Violet.

Turns out it's the cheap materials used in ChinaCraps.. LedEngin uses a "glass" dome, so that why "they" don't discolour...

Q: Spuzzum

quick question on UV diodes

hey

I have a quick question on UV diodes. I've seen pictures of cheap Chinese UV's, where the dome has turned colour and is no longer clear. In fact, it looked like a red dome. I've been told that's what UV does to the dome. I just figured they used a red dome on a blue diode to get purple

My question is.. do higher quality diodes, such as a LedEngin UV, do the same thing?

Re: quick question on UV diodes

Most of those use a resin of some sort, and will degrade over time. The lower the wavelength, the quicker it will discolor. The picture you posted is pretty typical for the cheaper "UV" LEDs (410nm isn't UV). LEDEngin LEDs use glass domes, so they shouldn't have any issues.[/b]

Evil66 is in the coral reef community, with his own shop.. he knows his LEDs

yeh 380nm is the ones that do the degrading...

I know he has gone back and forth, but yes his last root test validates IR. I must have been high when I posted, because I meant nutrients not nms? lol

Olivia's and a couple drops of SuperThrive

so no new fancy LED from max? probably not the best field to get into atm. considering lighthouse hydro (and many others) are getting very competitive .

 

[dbkick]

so whats this about IR promotes rooting? my blackstar has IR but I thought its addition was basically for mold and mildew prevention.

So what ever happended to Max & his new light? I was considering buying one of these. I am unable to send him a private message. This thread just kinda died.

keep it that way bro buy your panel from a reputable company, not some one man in his basement making money off panels he is redirecting from china .... just sayin bro
