The link you send is about a led that is 275nm..this is a very short wavelenght..very dangerous to you and the plants...You should look for leds that have 285-310nm... The 280nm ones are easy to find and cheaper..but in my opinion in also dangerous cause what you really need is in 285nmk and 310...

The 285 nm seoul viosys I bought was about 20$ per unit at digikey...There are cheaper options..but I bought the most efficient ones.

They have a beautiful spectrum..sadly are expensive and not efficient at all...

I did two aluminium bars with 2 seoul viosys 285 nm leds per bar. Each bar has also 9 UVA leds 365,385,410nm..well the 410 is near UVA..So..two different channels one for the UVAs..and one for the UVB.. There was also another group of 3 UVA leds per bar that were connected in series with the UVB...

Yes..you are right...Thats what I used.. You remember well! Have to say that I used the plants to UVB since veg...upping the potency slowly. I posted about it in other forum.. but for you to see the results here are some pics...genetics are personal from old landraces , not commercial, Can...

The best UVB led in market today is the seoul viosys regarding performance and self life, it cost about 20 $ each one..you need 4-6 leds per square meter...about 100 $. They should last about 3 years minimum...so 30 $ per year.. but probably less..uvb tubes should be changed every year... This...

Remember that with these short wavelenghts also need skin protection... What I did was insert some visible leds in series as a signal, so if I forget that UVB ones are running ..those leds will tell me the UVB are on. Also that signal notify me that UVB is doing its work..the UVB leds emit so...

I have used succesfully 60 mw output power of 285 nm UVB leds (seoul viosys) starting 30 minutes in veg and upping until 3,5 hours at maximun in flower. This mixed with cheap 365,385,410nm leds about a max of 30 watts of input power Area one square meter 280nm should be more tricky to...

You dont know what you are talking about.....Teknik knows lighting better than most of us and has spent his time for free educating some of us....

I have done it a few times...Viable for me about 8 months later...I did not try it more time than that...Just dry the pollen before freezzing it...works nice

Genetics plus UVA/UVB also cold temps

Look at the website, they give some advice on times https://www.solacure.com/superb.html

They are usable the two..the new Super B seems to be less potent in the 280-310nm range and slightly more potent than the Flower Power from 300-320nm.. So Super B is safer to use..but at the same time needs more time of exposition to provide same quantity of 280-300 UVB...it is a question of...

Solacure is much better option than Agromax..this has been stated here in RIU lot of times ....Agromax has an incorrect UVA/UVB ratio... One of the effects of UVA is protect from UVB damage...UVA/UVB ratio in nature is much more similar to solacure than to Agromax... IMHO avoid Agromax... But...

Nice work !

It works for me! Yes... lot of days waiting for the LIbreoffice Software to open it.. Lol! Nice done! Sadly my base leds are 3500K not 3000K

So beautiful....

I think they received similar PPFD if I remember well

Interesting to notice also the increase in CBD with the UVA/UVB suplemental...about a 20% or more

Probably much better distribution with 9 leds and use it at lower amps...but I was in a low budget ...
