EDITO: Finalmente compré 2 x Area51 XGS para una carpa de 1,2 mt x 1,2 mt (4x4 ft)
Última edición:
no los habia visto, parecen buenos.. pero sin reviews ni seguimientos de cultivo no me arriesgaria.www.gothamhydroponics.com/ ya buscaste aqui?? checala!!
pues eres la primera persona que leo que NO los recomienda PARA NADA mas que iluminar un dormitorio o cocina.Yo no los recomiendo para nada , he probado esos leds , los Cree de 5W y dan mucha luz pero se desperdicia casi toda. Aparte el warm white es blanco calido, no blanco frio.
Hay paneles mucho mejores y más baratos que llevan leds especificos y no de iluminación para una vivienda...
podrias indicarme donde estan esos fantasticos paneles con mejores leds, mas economicos y especificos ?Re(d)garding ....
Warm White leds (3000K 80 CRI ) ,
do provide a 5-10% of blue wls ( all what's needed,actually ....)
All what's needed is WW 3000K 80 CRI ....
(Or maybe NW 4000 K + WW 2700 K ,both 80 CRI )<= Another great white combo ...
No blue ,no red ,no NW ,No high CRI ...
Nothin' ...
Blast 'em with 600-800 umols/ sec / m^2 ,of WW 3000K led light ...
And just watch the SSL version of HPS ,how it ' helps' mj to grow thick dense crazy buds ...
So fuckin' simple ,is the best spectrum ...
Su post:To my eyes ,it seems as a rather exceptional panel ...
It lacks absolutely nothing ...
....
:roll:
Ok ...
Maybe ....
Some more power,would not have been an 'overkill' .
..Just maybe .. :dunce:
Cheers .

Además, en estos dias estan con una rebaja de $100 dolares por cada panel, osea, puedo conseguir 2 por $950 y en todo grow led los 3 paneles TGL100 me sale por $820 dolares. esto para mi carpa de 1 mt cuadrado x 2 mt alto. Garantia de por Vida v/s 1 año garantia.Re(d)garding ....
Red wls of 640-680 nm are mainly absorbed by the PhotoSystem 1 of each single leaf cell ...
These red wls provide vast numbers of photons ( >4.5 umoles/sec/ Radiant Watt ) which
get absorbed (mainly) by Chlorophyll A .Magnesium atom in the center of the chlorophyll A is
"biased" (with protein(s) ) towards absorbing light maximally at 640-680 nm range.
(Peak ~662nm ,not on alive cells,but measured at dilluted ChA ) ...
PS1 is considered the "High Energy Photosynthetic " system...
For high irradiances ..
For clean bright sky,at noon.
(Water/Vapour absorbs -thus 'filters out' mostly at red/FR wls ...
Under a cloudy sky blue and Green wls dominate (at PAR range ) )
Those wls (640-680 nm ) get highly absorbed by top layers of leaf canopy.
Where the younger leafs / shoots are ...
Older leaves ,are not able to efficiently absorb and use those wls.
Those wls also can cause Photosaturation of the PS1 in no time ...
If exposure is prolonged and or of high irradiances ....
Older leaves have to avoid the exposure ..
Younger (and more photosynthetic efficient ) leaves 'protect' thew older/deeper/lower parts of canopy ,
by absorbing the 'high Power Red wls ..."
Thus they grow like crazy ..
From the other hand ,older leaves have larger photosynthetic area ....
Thus they absorb and utilise very efficiently the Green,Yellow ,Amber and Lower red wls ...
( 500-630 nm )
They can photosynthesise for longer period of time ,than from top -young- canopy and almost in as high irradiances
,but on different wl range... (photons are also less than 640-680 nm range ,per radiant Watt ..But of higher energy each ...
That translates to heat ..Thicker older leaves ? )
The result is that plant(s) 'capture' as many 'energy quanta ' as possible and use them
accordingly -depending on 'quanta' 's characteristics (energy / wl / frequency/ numbers ) ,
to satisfy the different needs ,of different 'parts'- subsystems - of a living organism ....
Plants can adapt of course ...
To light quality and quantity ...
To altitude..
To growing techniques ..
To plenty of things ..
Warm White leds (3000K 80 CRI ) ,
do provide a 5-10% of blue wls ( all what's needed,actually ....)
About 15-20 % green wls ( 520-550 nm )
(pretty useful feature when irradiance (quanta flux ) is over ~300 umol/sec,
if irradiance is less than ~300umol/sec ,then some Shade Avoidance 'kicks in 'and that's
if only illumination used is WW leds ....)
At least 50% of their radiant power is at the range 550-640 nm ....
Some 15-20 % of power at 640-700 nm ....
And 1-3 % at 700-750 nm....
I trust that at average irradiances and above that ...(300 up to 1500-2000 umol/sec )
All what is needed ...
(And probably could not get better ..Ok ..
Maybe some ..Some UVA-UVB ..Maybe ...Some ...)
All what's needed is WW 3000K 80 CRI ....
(Or maybe NW 4000 K + WW 2700 K ,both 80 CRI )<= Another great white combo ...
No blue ,no red ,no NW ,No high CRI ...
Nothin' ...
Blast 'em with 600-800 umols/ sec / m^2 ,of WW 3000K led light ...
And just watch the SSL version of HPS ,how it ' helps' mj to grow thick dense crazy buds ...
So fuckin' simple ,is the best spectrum ...
