Hello growers!
So, is anyones went to the french website?
And honestly are you sure only white and red good enough for growing from a to z?!?
Cause all the (good) seller i know use (minimum) 6 band for flowering and there's no white in it and 5 for vegging with bleues, uv, and 2700k white + 6500k white and that work great.
So if anyone want to talk about it...no problem. Andi agree that many little lamp spread in the box are better than a big oone.oh!, and this kind of lamp cost 25 $ on aliexpress, but i buy the first one from a french shop 79 € and they are the same.
See you Ja friends

It's me again...
About your little "war" cob/diode for me cob is for penetration and pannels for more coverage.that is the difference.So if you scrog or suppercrop pannel or lamp are ok but for a "classic" crop you need cob (who exist in 7 and more wavelength)
C u guys!

Yes Jacob I am sure white and red will flower/veg from a to z, the white in the W/R LEDs has a lot of blue in it already so you don't need more blue chips. Here check this LED manufacturer out they use very good quality parts and such www.a51led.com . Thanks @littlejacob .

The white LEDs are effectively "broadband" LEDs, they put out a wide variety of wavelengths of light. The color they are rated at is where they produce the most light or the center of their band. A 6500k LED will put out light from red to very blue, but it puts out much more intense blue than it's weak red output. A 3000k LED will put out little blue and a lot of red. Using a 3000k and a 6500k together covers even more spectrum than using a 6 band LED system. If you add in UVB with 3000k and 6500k you hit every spectrum the plant can use. (All visible wavelengths, deep blues, UVA, UVB)

My goal is to hit all spectrums, but to have much higher intensity where it's most useful (3000k and 6000k line up with the most usable/absorbed wavelengths.)

Hello growers!
Ok we don't have the same approch in E.U, maybe it is because we like the beautiful purple light in our box (or i went to too many rave party...).
And i saw new diode 3w full spectrum and they are purple too, so i will keep my kind of spectrum
Just try it...you'll thank me later! And they make cob 7 band too
And i know area51 but it too expensive for something I'm gonna change in 1or2 years
See you U.S friend

Must of us have tried the blurple spectrum and also the R/W spectrum and prefer the R/W, at least I do. The blurple is more for growing leafy greens, not flowering annuals. I'm thinking about reusing my Chinese panels to grow some dank spinach and lettuce.

Did you see the picture of the lamp i use? It's not only bleu and red i have 2 kind of bleue, 2 kind of red, orange and I.R and i know only red and blue is not enough but the combinaison i use work very well.for a 18*3w lamp with your w/r spectrum which diodes will you use? And how much of each?
Thanks
See you mates...

My lights are 18*3w but really 20w and i use it since 1month so no result yet...but a guy i know made 2, 4g/w with the same, so... (with 4 in veg and 6 in flo)
See you soon

2.4 g/w !!! with a light mover??..........stationary is hard to believe, only a handful have done it since the internet exists..

g/watt is hard to believe unless using to measure your own grows. Very easy to cheat run the light for 24 hours divided up into 2 12 shifts, double the yield same light :)

If your talking about smoke able non-popcorn/trim , 2.4gpw sounds beyond impossible , if I can get 150 grams from my 160w area 51 light I consider that strain a very large yielder and the grow very successful, maybe I am just not a very good grower but I have grown some of the biggest yielding strains under HPS and couldn't ever get near 600 grams with my 600watt HPS light honestly 300-400grams is a successful grow for my hps.

HID or other light source? Hydroponics or organic? What strain? Size container? Veg time?

I had two plants in the cabinet and both did over 1.3 g/w, LSD and Death Star in 5 gal of soil with Cree CXA's and I think it was less than 8 weeks of veg, DS was about 3' tall and the LSD was maybe 2.5' tall.

Did you train them for your height restrictions? And using DIY lights is almost cheating for gpw numbers
