I just meant safer, as in compared to a newb making his first soldering attempts on creating an AC line. Not questioning that what you came up with isnt great stuff or isnt superior. Was talking about something like this...

Hi, would it not be easier, safer and cheaper just using a nano arduino ebay thingy for like 3$ and a compatible 2 1-2$ optocoupled relay shield?

Can you confirm that in agri greenhouse led lights have to be ip65 rated, Jet of waterstream resitant? That 50W design light for about 2000$ with passive cooling guod posted came to my mind ;-) I know it was a "design" thingy...but the heatsinksystem needed there seemed large

I asked someone who "said" (cant prove it) he works in that industry and he told me: -Initial capital Investment for quality IP65 (means to be able to shower with it) Led lighting is still too high -dual electrode HPS can use pre existing ballasts, which means nice gain and low Investment costs...

I rebuilt my cabinet with the air Intake at the top and exhaust at the bottom I also raised the flower section. My floor is very cold. This way now during lights out the air isnt that cold anymore and during lights on the temp is about perfect as im also "using" the leds heat that way.. Change...

Hgrow, that blue round led light in the first picture. It looks really nice, where can i get it? Do you have more photos?

I thought it would be finally over. For me that has nothing to do with honest reporting, seeing you mentioning it every 3rd post. Typing spydr into search and your name, confirms that you are overdoing it. (166times) Actually made me hate it.

Thx, I was just wondering, why not just make a close up photo of the diodes. Epistars are easily to be spotted. And if there is even one epistar.... trying to find that amare thingy with google all I find is you posting the same thing, same posts in several forums. Do you get money for that...

yes the text above the pics refers to the pic ;-) I was searching for what could be the cause and found pics similar with the description that that is lightbleaching. Im not a very experienced grower, could be something else I dont know of. I havent read anywhere that albino tops could be...

even my chinese WW/R combo gave one plant standing in the middle 3 albino bleached tips. Completly green besides that. I raised the lights and (dont know how long) later it was gone/ hidden edit: but my light is symmetrical and other plants were unaffected, so I think it might be straindependant

you find him on RIU in this very led section

can you show photos of what the 730nm light looks like for comparison purposes? I got some epistars. They are 15$ for 12pcs 3W on ebay

just type "cxa3070 bin" into google.. first hit

Why does AT write that on their homepage? lacking an update is one thing...

HPS emitts also heat in rays, directly heating the canopy. While a heater would just heat the air, as mostly would the led panel..

Phototropism. Discussed few posts before yours on last page. I was hoping you d bring something new to the table with your 61 led panels. :-(
