So true...

Yes..is easy with soldering paste.

You can grow perfectly with only with warm white lights... I make my own lights as do lot of people here...combining different leds and drivers. Each person can choosee its own recipes... Explaining you how to build a light is too long. You have all the information in this forum. I have a...

I use a DIY lamp..3500 K samsung, 660 osram, 730 osram, UVA and blue leds , UVB leds ..5 independent channels.. Yes I have spectrometer .Yes I have temp gun, I am using this kind of spectrum now, too high in blues and far red ..but I am just experimenting.. and also this..

I am using this Arcadia lamp for infrared and heating purposes...day and night It can be dimmed..it does not interfere with flowering photoperiod at night.. Much more efficient than ceramic black bulbs..but much more expensive The shape type of the emission due to the lamp form is not...

Forget the 55 degrees viewing angle...is not appropiate this kind of light spread...if you want 365 ...look for more 120 degrees or more.

295nm and 310nm are difficult to find , 285 is much more easy, and probably cheaper, but if you find them I think they are better and more safe... Better than using watts as a way to calculate UV irradiation...use radiant output power...cause same wats can give different amounts of UV...with...

Well.. when you have a 285 nm led..of course 285 is the peak of its emission and it emits some light in closer wavelenghts...Lower than 285 and you are in UVC territory...So even a 285 is dangerous...for this reason you should use it with caution...But if you initially use a 280 nm or lower...

Dont use that lamp..has UVC not UVB..is dangerous It is worth! UVA itself has benefits of course, shorter plants, more colors, denser buds, and probably certain increase in THC..probably not as much as with UVB addition... Whatch results of UVA and UVB leds added...

HI again, solacure is a good brand , they sell quite potent lamps, I have not used then , before leds I was using arcadia tubes, but I think solacure are much better..I like their broad UVB/UVA spectrum. Their specs in that model said to use two lamps every 1000 Watts HPS...well this is more or...

Well..first..emerson effect can be used all plants live cycle..exactly as it happens in nature...just mantain a good red/far red ratio with a bigger amount of red so a positive ratio..like happens with the sun.. Other thing... EOD treatment is always after lights are off...and of course you...

That luminus UVB led is interessting but if you read the specs ..you will see that to emit more light in the correct wavelenght (285) you have to drive it at high amperage.. 800ma..and they give 80 mw output power..this means that you need only one led each square meter..and this will not...

Feliz navidad desde el Pirineo! Yes, Teknik has sent me recently some UVA leds and a prototype of his blue buddies among other goddies. I will test all in next grow..still need to solder the bare leds to the starboards cause he sent me some bare nichias. in roll packet...Right now I am using...

Its ok, it was not clear and maybe confusing the way it was posted in the previous post....385 nm and probably any UVA wavelenght and even probably just near UVA or blue light also protects the plant of the potential negative effects of the UVB light.

A better approach ..could be use 295 nm leds for a longer time, this way you provides a little more 310 nm light...and still have good activation of the UVR8...but those leds are expensive and rare to find...
