Money no object: I want a 1000w LED full and adjustable spectrum light. Your opinions matter!
Adjustable Spectrum Fixtures

You don't have to spend a lot of money to grow weed with LEDS anymore. Check our vendors sub-forums for some prices on 1000w LEDs. You would be surprised.
I do have a Mars Hydro FC 3000 for the veg. I would like a fixture in the 1k range that I can tweak the spectrum for the flower tent. I am not too savvy about the various manufacturers and their products.
.. and I seem to gravitate to that old adage : Buy Once Cry Once.

Do you have the option to veg with about 600 of a colour you like. Then add 400w of warmer light?
Presuming that is what you want. Perhaps you want IR and UV to play with.
A 1000w watt light, will be rated with everything switched on. Anything not in use, might be a waste of time having. Just power you are not using. I have not seen a light divert it's power between different banks of LED. Though one may exist, I think it's mostly all about cool whites and warm whites, with their own drivers. Maybe a separate 660, and the IR and UV tend to be grouped. Maybe with a driver, maybe just with the 660s.
To build with separate control of UV, IR, 660, Warm and cool, you need 5 drivers onboard. I have not seen this outside of crazy money experimental lighting. Where more people would just buy separate lights/bars instead.

About 10 or 12 years ago, I had a hard on for adjustable spectrum lights. Pretty sure luma grow was the first manufacturer to market these adjustable spectrum lights. Bought two of these for $750 a piece:
Concentrated on a blue dominant during veg and red dominant during flowering. After a couple of grows, came to the harsh conclusion that it really didn't make _any_ difference adjusting the frequencies. The plants that did consistently the best were on 100% of all colors, 100% of the time.
However, it was a hell of a replacement for this 1980s monstrosity that I used for 20 plus years
:Bottom line for ya HJ, and obviously this only my opinion, but I would concentrate on getting the best possible light for your square footage and wouldn't worry about it being adjustable for spectrum.
Here's my lighting history, so you'll know I'm not talking out my ass
:What is your lighting history?
I've been following the LED and Bud Quality thread for a while now and even an old geezer like me can't believe growers are still debating this topic. With various participants slamming their dicks/clits down, saying either LEDs suck or they're the best, I thought it might be a good idea to see...

Yowsa!
If I were a rich man and not a retiree living on a fixed income (Hyman Roth from The Godfather
), I'd be all over giving this one a shot. Wish it had a 5-year instead of a 3-year warranty.
Woo wee!! $1800.. I know I said money no object but.. yikes!
@CharlesU Farley their website specs state that the fixture does carry a 5 year warranty.
What parts of the spectrum would you like to adjust? Its fairly easy to build. But anything like that is going to cost you even if you diy
Take a look at the new Mars hydro "adlites"...you could pair an fc8000 with the addition uv, ir, and far red bars which allows you to time each bar separately independent of main light. Total wattage would be over 940w.
Would be around $1000 all in, or less with a sale.
Or something like this light

I'm imagining giving the girls increased blue at the beginning of veg, full spectrum later veg into 80% flowering then a blast of red and UVB towards the end of bud cycle. Waste of time and money? I dunno.
When I was younger I enjoyed building little projects.. now, tiny parts and me dont jive
I added the old style uva/ir bars to my MH fc8000's and run them 2hrs on 1 hr off with main light schedule. I noticed better terps, potency and bud density. Played around with all kinds of different schedules with them but they are limited by design, both uv and ir are wired to the same ballast which makes it difficult to time them separately.Thanks for your suggestion. All options open at this juncture
uva will do what you want without the damage uvb inflicts....."Emerson effect" is an interesting rabbit hole to run down.
Hey harley i have a present for ya! I haven’t forgotten about ya pal check out how healthy daz has gotten the skunkbud cut aka rks he was pleasantly surprised!Thanks for your suggestion. All options open at this juncture

Ive played around enough with this to see that its beneficial and worth it for the grow i work on but theres a big "its complicated" in there; the effects of adding spectrum depends partially on what spectrum you start with.I'm imagining giving the girls increased blue at the beginning of veg, full spectrum later veg into 80% flowering then a blast of red and UVB towards the end of bud cycle. Waste of time and money? I dunno.

Its also important to figure out what it is that you want from your light and design from there; adding +2 channels is a bit of a mess since it is hard to get an idea of what each one does to your plant on its own vrs whats the effect of total spectrum.
From what I gather the blue spectrum will reduce the plant's vertical growth in veg; especially helpful when dealing with leggy sativas. The full spectrum -- well, that goes without saying. At the near end of flowering the red and UVB would make her extra hot & horny; bringing out the finishing touches to the oils and terps.

From the mid '80s, until I obtained the Northern Lights seeds from @Gypsy Nirvana in 1999, I grew nothing but sativa dominant plants that were developed by the Zion Coptic Church in Jamaica in the early '70s:
I always put this pic in from back in the day, film and photo developed and printed at Fotomat.
That's why I used the MH, once I had to move indoors due to a vindictive ex-wife.
I used to argue/debate with Vic High on the BCGA website regarding MH versus HPS for shortening internode length.
I used MH to tame those wild sativa hybreds so they wouldn't grow so tall.
Glad you're doing so much better medically!!! As long as you don't die when they insert them, aren't stents fucking wonderful???

Would I like to get my hands on some of those Jamaican beans! Sativa/dom cultivars are my medicine. Its strange.. Sativas alleviate my neuropathic pain while indica/dom acts as a trigger.
The stents are fuckin great. I have more energy and I can even breathe better. Miracles of modern medicine!
