I don't expect R/B/G leds coverage will improve much, however, a grower on another site is vegging under mostly Cree Neutral Whites. His DIY fixture had ~ 40% 660s, but he replaced most of them with more NWs, and is loving the veg results. One ~ 6" wide fixture is doing a very nice job covering a 20 x 30.
As I have been saying for a long time, the future was/is in NWs, and now that they light a bigger area, well...
Companies like www.rapidled.com make solderless kits that allows you to select the diode spectrums @< $2/watt

Oh, riu breeder seeds... So cryptic. I'm intrigued. lol. As long as it isn't more subcool shit.
So whats the story with the panels? If hans gives you another one you'll do an all hans grow and if not you'll purchase an indagrow 100 and do a side comparison?
Cpt M: This is an indirect answer to your question. I think it's important to bring others up to speed on LED tech.
Slowly, we are learning that the 460-590 are important to highest quality, meaning RB alone never was the answer 100%. The majority of led manufactures focused on R/B, any other spectrums were hard to come by and very expensive, up until ~ 2 years ago. But it takes fixture mfgs that long to incorporate new tech due to things like inventory. Until they draw down their inventory they aren't releasing newer tech. And if they do, it is many times more expensive.
LED tech is a lot like computer chip tech- storage=white diode tech is doubling ~ 9 months, BUT, we don't see it commercially for several years, not so with DIY.
If you think of the sun in electrical terms it's Analog, whereas indoor lighting is like Digital. Sony introduced the SACD music format~ 10 years ago. It is the closest medium to this day to matching analog, but Sony priced its' use beyond main stream mfgs, let alone DIYers. The existing commercial digital formats will never reproduce analog 100%. For most people that missing ~ 10% doesn't matter, but in mmj? MMJ requires roughly 10-20% of 460-590nms, which act as a catalyst to the others.
Today, companies like CREE have introduced Neutral Whites which provides ALL the spectrums indoor gardens need in a single bulb in ample quantities.
A DIY led thread on another site: a guy uses a Kessil 350 but has built parallel runs of CREE NWs (~20w). These and just about anything you want is available as DIY solderless kits! On that site another has a DIY who started a grow where he mixed R + NW. He decided to remove all but 4 Rs (I forget which nm, but probably 660s) and is blown away by the vegging performance AND coverage. My idea is R (660) should be on a separate circuit/on off switch to be used from flower- harvest.
Rapidled has solderless kits using 5w CREES (nms buyer choice!), outputs range 60-120 watts. The 4.5 X 23 @ ~150w is $250 (covers ~ 20 X 30"), including tapped/drilled heat sink. They are made with better quality parts, use no fans (noise) with the BEST leds currently available
On the issue of heat with my 8 lamp T5,it has dual ballast with 2 switch's. How much heat could I remove from my cabinet by rewiring it and moving the ballast's outside the cabinet? What percent of the heat do you think the ballast's put out compared to the lamps?
psuagro they llook good other that they are taking longer I really dont know how you could be so upset man 56watts and you are getting some nice looking buds. I am sure you will easily do better next time around but this isnt too shabby !!
